- Basic anti-aliasing
- Phong shading
- Anti-aliasing
- Implement Xiaolin Wu's line drawing algorithm. Create additional MDL "aaline" command to draw an anti-aliased line. Bresenham's algorithm will still be used for scanline conversion and zbuffer. Xiaolin Wu's algorithm will be used just to draw lines, not filling polygons.
- Phong shading
- Implement shading MDL command to toggle between "phong" and "flat" shading models
Examples:
make- generates image (test.png) comparing the line algorithms, flat shading, and phong shading
make cube- generates gif (cube_spin.gif) of spinning cube using phong shading
Relevant MDL commands: aa_line and shading
- aa_line
- Takes in arguments: x0, y0, z0, x1, y1, z1 but NOTE: does not take into z-values into account; the default z value used is always 0
- otherwise, can be used the same as "line" command
- Example use:
aa_line 0 0 0 250 -500 0
- shading
- Takes in an argument: either flat or phong
- Example use:
shading phong
