Gouraud Interpolative Shading

computer-graphics

A way of shading in which we [see page 27, bilinearly interpolate] vertex intensities over the polygon to determine the intensity at each pixel.

What this means is that we calculate the color intensity at each vertex of the polygon
and then interpolate between these colors for each pixels in the polygon.

This process calculates intensities only at vertices, meaning it has [see page 30, difficulty] with specular highlights when the number of polygons is few.
