Selective ViewCapture

With a simple click, the Grasshopper script screenshots specified regions in the Rhino view directly into images (.jpg/.png).

It offers the following functions:

• Outputting images that are dimensionally accurate (useful for creating mapping textures),
• Batch outputting multiple images at once (useful for streamlining design workflow).
• Fast overwriting existing images

👆Please feel free if my scripts had been useful for your projects. :)

Usage

1. Download selective_viewcapture.gh and open with Rhino.
2. Reference the specified region(s) as retangular curve(s) and input into frame.

if frame is not connected, the entire current view will be outputted (same as the rhino command ViewCaptureToFile).

3. set image resolution in res component.

the output image size will be frame.width*res x frame.height*res px

4. Specify the folder destination and file name at path and filename.

if frame has multiple inputs, filename shall have the same number of inputs

5. Click capture to create the image(s) at the designated location.

Examples

- batch outputting array of image frames (see more from my pat_writer project)

exporting several images at once (ensure `filename` also has multiple inputs)

- images with accurate computational patterns
