WebShading is applying lighting effects in OpenGL code. The three ways below are in increasing realism, but also each take a higher performance hit. Flat Shading Gouraud Shading Phong Shading Comparison of shading and normals In summary, it’s something like this: 3.2.1. Flat Shading ¶ WebOpenGL defines two particular shading models: Controls how colors are assigned to pixels Gouraud shading:interpolatesbetween the colors at the vertices(the default) glShadeModel(GL_SMOOTH) Flat shading: uses a constantcolor across the polygon glShadeModel(GL_FLAT) Phong Shading

WebGouraud shading. Flat shading does not look realistic: Gouraud shading is better. OpenGL uses scan-line interpolationto assign a colour at each point of a projected polygon as a weighted average of given vertex colours.

This is because only lighting at the vertices is calculated. Phong shading is the next step up, but takes a lot longer to calculate. If you get this problem, subdivide your polygons.

WebImplementing flat shading. Per-vertex shading involves computation of the shading model at each vertex and associating the result (a color) with that vertex.
