- One triangle on a textured background. The triangle is created by
- specifying the screen coordinates for the vertices using TLVERTEXs.
-
- The top left vertex, the first vertex in the triangle data, has a
- diffuse color of blue. Switching between flat and gouraud shading
- changes the effect this vertex has on the lighting across the
- triangle. When flat shading, the first vertex specifies the lighting
- for the entire triangle. When gouraud shading, the lighting is
- interpolated across the triangle. Lighting is different in the two
- software renderers. The RAMP driver does not modulate the texture's
- color with the material color.
-
- The rhw value of the top right vertex is larger than the other
- two; it is closer to the eye. Turning perspective correction on and
- off changes the interpolation of the texture across the triangle.
