Polygon Texture-Mapping and Texture-Windowing

SOURCE CODE AND EXECUTABLES:
 

• PCX image file handling routines
• Texture-mapped / Texture-Windowed Triangle Rasterizer
• Slower, unoptimized version of texture-mapped, span-array-based, scanline depth-buffered triangle rasterizer
• Faster, optimized integer-based version
• Test program: triangle kaleidioscope

SAMPLE OUTPUT:
 

Triangle that is texture-mapped with the background image. The picture shows me (left) with friend Jay (right) at UNCG.

 

Triangle used as a window into the background image. The texture applied to the triangle is triangular "window" region of the background.

 

Texture-mapping several polygons with varying textures on a scrolling background image. All of the images are .PCX files that have to made to share a palette of 256 colors. Here the triangles are scanline Z-buffered during rasterization.
