+*Design decision for QuickViz point cloud selection system* +*Date: August 26, 2025* + +## Problem Statement + +The current ray-casting point selection system has fundamental limitations that prevent robust point cloud interaction: + +### Issues with Current Ray-Casting Approach + +**Occlusion Problems**: +- Ray can pass through multiple points at different depths +- Selection algorithm may pick background points instead of visible foreground points +- No automatic handling of point visibility from camera perspective + +**Camera Sensitivity**: +- Ray calculations depend heavily on camera position and orientation +- Small camera movements can drastically change selection behavior +- Ray origin often positioned outside point cloud bounds, causing distance calculation issues + +**Tolerance Ambiguity**: +- Difficult to determine appropriate tolerance values for different point densities +- Too small: miss intended points; too large: ambiguous selections +- Tolerance needs vary with camera distance and point cloud scale + +**Performance Limitations**: +- O(n) brute force search through all points for each click +- No spatial optimization for large point clouds +- CPU-bound algorithm cannot leverage GPU parallel processing + +**User Experience Issues**: +- Selected point may not match what user visually sees on screen +- Inconsistent behavior across different viewing angles +- Poor precision for dense point clouds + +## Proposed Solution: GPU ID-Buffer Picking + +### Core Concept + +**GPU ID-Buffer Picking** is the industry-standard approach used by professional visualization tools (ParaView, CloudCompare, MeshLab, etc.). The technique renders the scene off-screen with each point assigned a unique color ID, then reads back the pixel color at mouse position to determine which point was clicked. + +### Technical Approach + +#### 1. **ID Encoding Strategy** +- Encode point indices in RGB color values (24-bit → ~16M unique IDs) +- ID = `(R << 16) | (G << 8) | B` +- Point index = ID - 1 (reserve ID 0 for background) +- Handle point clouds with >16M points via tiling or 32-bit RGBA encoding + +#### 2. **Rendering Pipeline** +```cpp +// Main rendering pass (visible to user) +framebuffer_main.Bind(); +point_cloud.Render(NORMAL_MODE); + +// ID picking pass (off-screen) +framebuffer_id.Bind(); +glClearColor(0, 0, 0, 0); // Background = ID 0 +point_cloud.Render(ID_MODE); +``` + +#### 3. **Point Selection Process** +```cpp +// Mouse click event +glm::ivec2 mouse_pos = GetMousePosition(); + +// Read pixel from ID buffer +framebuffer_id.Bind(); +GLubyte pixel[3]; +glReadPixels(mouse_pos.x, mouse_pos.y, 1, 1, GL_RGB, GL_UNSIGNED_BYTE, pixel); + +// Decode point index +uint32_t id = (pixel[0] << 16) | (pixel[1] << 8) | pixel[2]; +size_t point_index = (id > 0) ? id - 1 : INVALID_POINT; +``` + +#### 4. **Shader Implementation** +```glsl +// ID picking vertex shader +#version 330 core +layout (location = 0) in vec3 position; +uniform mat4 projection; +uniform mat4 view; +uniform mat4 model; + +void main() { + gl_Position = projection * view * model * vec4(position, 1.0); + gl_PointSize = point_size; +} + +// ID picking fragment shader +#version 330 core +uniform uint point_id; +out vec3 fragColor; + +void main() { + // Circular point shape (discard pixels outside circle) + vec2 coord = gl_PointCoord - vec2(0.5); + if (dot(coord, coord) > 0.25) discard; + + // Encode point ID in RGB + fragColor = vec3( + float((point_id >> 16) & 0xFF) / 255.0, + float((point_id >> 8) & 0xFF) / 255.0, + float(point_id & 0xFF) / 255.0 + ); +} +``` + +### Advantages Over Ray-Casting + +**Pixel-Perfect Accuracy**: +- Selected point exactly matches what user sees on screen +- Automatic handling of overlapping points via depth testing +- No ambiguity about which point should be selected + +**Occlusion Handling**: +- GPU depth buffer automatically handles point visibility +- Only frontmost points can be selected +- Perfect handling of dense point clouds with layered structure + +**Camera Independence**: +- Works regardless of camera position, orientation, or projection type +- No sensitivity to camera distance from point cloud +- Consistent behavior across all viewing angles + +**Performance**: +- Leverages GPU parallel processing for ID rendering +- O(1) selection time regardless of point cloud size +- Minimal CPU overhead for pixel readback + +**Scalability**: +- Handles point clouds from hundreds to millions of points +- Memory usage scales with framebuffer size, not point count +- Easy to extend with area/brush selection tools + +### Implementation Strategy + +#### Phase 1: Core Infrastructure +1. **Extend PointCloud Renderable**: + - Add ID rendering mode alongside normal rendering + - Implement ID encoding in shaders + - Support for switching between render modes + +2. **GlSceneManager Integration**: + - Add dedicated ID framebuffer with same dimensions as main buffer + - Render ID pass before/after main rendering pass + - Provide mouse-to-point-index API + +3. **InteractiveSceneManager Integration**: + - Replace ray-casting with framebuffer pixel reads + - Maintain existing selection callback interface + - Preserve current modifier key behavior (Ctrl+Click, etc.) + +#### Phase 2: Enhanced Features +1. **Radius Picking**: + - Read 3x3 or 5x5 pixel block around mouse position + - Return closest point among candidates + - Provides tolerance without distance calculations + +2. **Area Selection Tools**: + - Rectangle selection: render selection region, read all pixels + - Lasso selection: render arbitrary polygon, read enclosed pixels + - Brush selection: continuous area picking during mouse drag + +3. **Performance Optimization**: + - Lazy ID buffer updates (only when needed) + - Framebuffer size optimization (can be lower resolution than main buffer) + - Memory pooling for pixel readback operations + +#### Phase 3: Advanced Features +1. **Hybrid CPU/GPU Approach**: + - GPU picking for single-point precision + - CPU k-d tree for region queries and algorithms + - Best of both worlds: precision + advanced queries + +2. **Large Point Cloud Support**: + - Tiling for >16M point clouds + - Level-of-detail integration + - Streaming point cloud support + +### Integration with Existing Architecture + +#### Minimal Changes Required +The GPU ID-buffer approach integrates cleanly with QuickViz's existing architecture: + +**PointCloud Class**: +- Add `SetRenderMode(RenderMode::kIdBuffer)` +- Existing shader infrastructure supports mode switching +- Layer system remains unchanged + +**GlSceneManager**: +- Add ID framebuffer as member variable +- Existing framebuffer utilities support additional buffers +- No changes to object management or rendering pipeline + +**InteractiveSceneManager**: +- Replace `PickPoint()` call with framebuffer read +- Maintain existing callback and selection mode interfaces +- No changes to user-facing selection API + +#### Backward Compatibility +- Keep existing ray-casting code as fallback option +- CPU k-d tree remains for region/analytical queries +- Existing selection visualization system unchanged + +### Technical Considerations + +#### Memory Usage +- ID framebuffer: `width × height × 3 bytes` (RGB) +- For 1920×1080: ~6MB additional GPU memory +- Negligible compared to point cloud vertex data + +#### Precision Limitations +- 24-bit encoding supports ~16.7M unique points +- For larger clouds: 32-bit RGBA encoding or tiling approach +- Most practical applications well within 16M point limit + +#### Performance Impact +- Additional render pass: ~1-2ms for typical point clouds +- Pixel readback: <1ms for single pixel or small regions +- Overall selection latency: <5ms (vs 10-50ms for ray-casting) + +#### Error Handling +- Background color (ID 0) indicates no point selected +- Invalid IDs handled gracefully with bounds checking +- Framebuffer read failures fall back to ray-casting + +## Conclusion + +GPU ID-buffer picking provides a robust, industry-standard solution that addresses all limitations of the current ray-casting approach. The implementation integrates cleanly with QuickViz's existing architecture while providing pixel-perfect selection accuracy and excellent performance scaling. + +This approach will provide users with intuitive, reliable point selection that matches professional visualization tools, while maintaining the flexibility to extend with advanced selection features in the future. + +## References + +- [OpenGL Red Book: Color Index Mode and Picking](https://www.opengl.org/archives/resources/features/KilgardTechniques/oglpitfall/) +- [ParaView Selection Implementation](https://www.paraview.org/Wiki/Selection_Implementation_in_VTK_and_ParaView) +- [Real-Time Rendering: Selection and Picking Techniques](https://www.realtimerendering.com/) \ No newline at end of file From ce38561b0f68cb19575d252b6bee4d674f77ab47 Mon Sep 17 00:00:00 2001 From: Ruixiang Du Date: Tue, 26 Aug 2025 14:18:59 +0800 Subject: [PATCH 32/88] point_cloud: removed debugging check for point vertex range --- src/gldraw/src/renderable/point_cloud.cpp | 4 ---- 1 file changed, 4 deletions(-) diff --git a/src/gldraw/src/renderable/point_cloud.cpp b/src/gldraw/src/renderable/point_cloud.cpp index 5c12c91..b220a19 100644 --- a/src/gldraw/src/renderable/point_cloud.cpp +++ b/src/gldraw/src/renderable/point_cloud.cpp @@ -811,10 +811,6 @@ size_t PointCloud::DecodePointId(uint8_t r, uint8_t g, uint8_t b) { } else { // We used base_id = 1, actual vertex index = id - 1 uint32_t vertex_index = id - 1u;

+float y_ndc = 1.0f - (2.0f * mouse_y) / window_height; + +// Unproject through inverse matrices +glm::vec4 ray_clip(x_ndc, y_ndc, -1.0f, 1.0f); +glm::vec4 ray_eye = inverse(projection) * ray_clip; +glm::vec4 ray_world = inverse(view) * ray_eye; + +// Ray from camera position +ray.origin = camera_position; +ray.direction = normalize(ray_world); +``` + +### Coordinate System Transformation + +QuickViz uses Z-up coordinate system internally but transforms to OpenGL's Y-up system for rendering. The selection system handles this by: + +1. **Ray stays in OpenGL space**: The ray is generated in the transformed (Y-up) space where the camera operates +2. **Bounding boxes are transformed**: Object bounds are transformed from Z-up to Y-up before intersection testing + +```cpp +if (use_coord_transform_) { + // Transform all 8 corners of the bounding box + glm::vec3 corners[8] = { /* ... */ }; + + glm::vec3 new_min(FLT_MAX); + glm::vec3 new_max(-FLT_MAX); + + for (auto& corner : corners) { + glm::vec4 transformed = coord_transform_ * glm::vec4(corner, 1.0f); + new_min = glm::min(new_min, glm::vec3(transformed)); + new_max = glm::max(new_max, glm::vec3(transformed)); + } + + // Use transformed bounds for intersection + min_bounds = new_min; + max_bounds = new_max; +} +``` + +### Ray-Box Intersection + +The system uses the slab method for ray-AABB (Axis-Aligned Bounding Box) intersection: + +```cpp +glm::vec3 inv_dir = 1.0f / ray.direction; +glm::vec3 t_min = (min_bounds - ray.origin) * inv_dir; +glm::vec3 t_max = (max_bounds - ray.origin) * inv_dir; + +glm::vec3 t1 = glm::min(t_min, t_max); +glm::vec3 t2 = glm::max(t_min, t_max); + +float t_near = glm::max(glm::max(t1.x, t1.y), t1.z); +float t_far = glm::min(glm::min(t2.x, t2.y), t2.z); + +// Ray intersects if t_near <= t_far and t_far >= 0 +if (t_near <= t_far && t_far >= 0) { + float distance = t_near >= 0 ? t_near : t_far; + // Object is hit at this distance +} +``` + +## Adding Selection to Custom Objects + +### Step 1: Enable Selection Support + +```cpp +class MyObject : public OpenGlObject { +public: + bool SupportsSelection() const override { + return true; + } +}; +``` + +### Step 2: Provide Bounding Box + +```cpp +std::pair GetBoundingBox() const override { + // Return min and max corners of your object's bounds + glm::vec3 min_bounds = position_ - glm::vec3(width_/2, height_/2, depth_/2); + glm::vec3 max_bounds = position_ + glm::vec3(width_/2, height_/2, depth_/2); + return {min_bounds, max_bounds}; +} +``` + +### Step 3: Implement Visual Feedback (Optional) + +```cpp +void SetHighlighted(bool highlighted) override { + if (highlighted) { + // Save original appearance and apply highlight + original_color_ = current_color_; + current_color_ = glm::vec3(1.0f, 1.0f, 0.0f); // Yellow + } else { + // Restore original appearance + current_color_ = original_color_; + } +} +``` + +## Example: Sphere Selection + +Here's how the Sphere class implements selection: + +```cpp +class Sphere : public OpenGlObject { +private: + glm::vec3 center_ = glm::vec3(0.0f); + float radius_ = 1.0f; + glm::vec3 color_ = glm::vec3(0.7f, 0.7f, 0.9f); + glm::vec3 original_color_; + bool is_highlighted_ = false; + +public: + bool SupportsSelection() const override { + return true;

+ if (highlighted) { + original_color_ = color_; + color_ = glm::vec3(1.0f, 1.0f, 0.0f); // Yellow highlight + } else { + color_ = original_color_; + } + } +}; +``` + +## Usage Example + +```cpp +// Create scene manager +auto scene = std::make_shared("3D View"); + +// Add selectable objects +auto sphere = std::make_unique(glm::vec3(0, 0, 1), 0.5f); +scene->AddOpenGLObject("sphere1", std::move(sphere)); + +// Set selection callback +scene->SetObjectSelectionCallback([](const std::string& name) { + if (!name.empty()) { + std::cout << "Selected: " << name << std::endl;

Create scene panel (replaces SceneViewPanel) +auto scene_panel = std::make_shared("3D Scene"); + +// 2. Set up backend (wraps existing gldraw) +scene_panel->SetRenderBackend(std::make_unique()); + +// 3.

no naked GLuints +- **Buffer usage**: + - Static: `glBufferData` or `glBufferStorage` + - Dynamic: `glMapBufferRange` with appropriate flags +- **Batching**: Sort by program → material → geometry +- **Minimize readbacks**: Only read pixels for picking; never read large buffers per frame + +### GL Pass Pattern +```cpp +class Pass { + public: + void Execute(const View& view) { + BindFbo(); + ConfigureState(); // depth/blend/cull + UseProgram(); // bind UBOs/textures + DrawAll(); // VAO binds and draw calls + } + private: + void BindFbo(); + void ConfigureState(); + void UseProgram(); + void DrawAll(); +}; +``` + +## Coordinate System & Precision + +- **CPU double, GPU float**: Keep CPU transforms in `double`;

The selection system remains agnostic to specific application domains, making it suitable for navigation graphs, scene editing, sensor networks, or any other graph-based visualization needs. \ No newline at end of file diff --git a/src/gldraw/include/gldraw/renderable/line_strip.hpp b/src/gldraw/include/gldraw/renderable/line_strip.hpp index 02bee3c..e8f4462 100644 --- a/src/gldraw/include/gldraw/renderable/line_strip.hpp +++ b/src/gldraw/include/gldraw/renderable/line_strip.hpp @@ -48,6 +48,16 @@ class LineStrip : public OpenGlObject { void OnDraw(const glm::mat4& projection, const glm::mat4& view, const glm::mat4& coord_transform = glm::mat4(1.0f)) override;

While currently functional, improvements would benefit future GUI development. \ No newline at end of file diff --git a/src/core/CMakeLists.txt b/src/core/CMakeLists.txt index 4fba1e4..99b7361 100644 --- a/src/core/CMakeLists.txt +++ b/src/core/CMakeLists.txt @@ -5,7 +5,6 @@ find_package(Threads REQUIRED) add_library(core # widgets src/buffer/buffer_registry.cpp - src/event/event_dispatcher.cpp src/event/async_event_dispatcher.cpp) target_link_libraries(core PUBLIC Threads::Threads) target_include_directories(core PUBLIC diff --git a/src/core/include/core/event/event.hpp b/src/core/include/core/event/event.hpp index e5b6602..dddef90 100644 --- a/src/core/include/core/event/event.hpp +++ b/src/core/include/core/event/event.hpp @@ -19,8 +19,12 @@ enum class EventSource : int { kKeyboard, kMouse, kMouseButton, + kMouseWheel, + kMouseDrag, kUiElement, kApplicaton, + kInput, // General input events + kSelection, // Selection-specific events kCustomEvent };

breaks multi-window use. + - File: `src/imview/src/window.cpp` +- Improve: Centralize GLFW init/term in an `Application`-level owner or use ref-counting; windows only destroy their own contexts. + +### CMake options and link scopes +- Add `option(ENABLE_AUTO_LAYOUT ...)`, `option(ENABLE_TUI_SUPPORT ...)`, `option(IMVIEW_WITH_GLAD ...)` with defaults and help strings. +- Use proper scope for compile definitions and link interfaces;

The bridge in particular was unsound: it dynamic_cast'd renderables and fabricated random fallback data via std::random_device when it could not clone arbitrary OpenGlObjects, so the "integration" demo was not actually mirroring state to the renderer. Editing/undo/history will be rebuilt on top of the library inside sample/editor/ so that the library proper stays a pure visualization toolkit. The sample will serve as a dogfood check: if it cannot be implemented without modifying src/, the library is missing a hook. Build configures and links cleanly. Pre-existing PCLLoaderTest.InvalidFileError failure is unrelated (PCL no longer throws on corrupt PCDs).

Codify the rule and enforce it: - CLAUDE.md: document the boundary explicitly under "Library Boundary", refresh the module list (add pcl_bridge, note sample/), and frame samples as a dogfood check on library completeness. - CI: add a boundary-check job that fails if any src/ source includes from sample/, or if any src/ CMakeLists pulls in a sample subdirectory. Runs fast on Ubuntu and gates the rest of the pipeline naturally. CMake target hygiene was already correct (modules expose include/ via BUILD_INTERFACE only), so no Makefile changes needed.

Documented the modal SceneState design that has been removed; useful only as a "what we tried" note, and we have it in git history. TODO.md: rewritten. Removed self-grading and the deleted scenegraph roadmap.

Built cleanly against the current library, no src/ changes. MVP scope: - Load a .pcd / .ply via pcl_bridge - Render in a viewport with the library's SelectionManager and PointSelectionTool - Delete the selected points (one undoable command) - Sample-private CommandStack with Undo/Redo, bound to Ctrl+Z / Ctrl+Shift+Z / Ctrl+Y, plus a "Delete Selected" button and a minimal history panel - Esc clears selection, Delete/Backspace fires the delete command Architecture: the editor holds the loaded data as the source of truth (an alive-mask over the original point array). The library's PointCloud renderable is the view; commands mutate the alive mask and rebuild the visible cloud via PointCloud::SetPoints. Selection events arrive with visible-cloud indices, which the editor maps back to original-array indices through a small lookup table. Library-hook candidates discovered while building the sample have been logged in TODO.md (Step 4 of the reshape plan): - Stable ObjectId-based access on SceneManager - ObjectId field on PointSelection - PointCloud::SetActiveMask / SetActiveIndices to avoid rebuilding the vertex buffer on every edit - Stable point identity so selections survive cloud mutations These are additive, not blocking; each will be evaluated against the "is this a visualization concern?" bar before merging into src/.
