Rasterizer: Implemented transformations, triangle rendering, depth blending, interpolation, mip-mapping for texture anti-aliasing, and supersampling.
Before
After
Transforms
Implemented scene graph transformations by completing local_to_world() and world_to_local(), enabling hierarchical object positioning through scaling, rotation, and translation in world space.
Line, Triangle Rasterization & Depth Testing
Line rasterization - Bresenham's Algorithm and diamond-exit rule.
Triangle rasterization - Standard Algorithm and top-left rule for intersection.
Alpha blending and depth testing for correct pixel composition
Triangle Interpolation
Interpolated triangle vertices' positions using barycentric coordinates. Screen-space smooth triangles (3rd cube) and perspective-correct triangles (4th cube)
Mip-Mapping for texture anti-aliasing and sampling
Nearest, bilinear and trilinear sampling. Ordered levels from high-res to low-res along the z-axis.
Before
After
Supersampling
Implemented a framebuffer for subpixel sampling and weighted color averaging to enhance anti-aliasing, adjusted clipped vertex positions for smoother edges, and applied texture mapping with bilinear filtering
