/* * REGISTERABLE ENUM: SE_Shading_Method * * This data type is used in <Rendering Properties> instances to * specify the illumination method. */typedef SE_Short_Integer SE_Shading_Method;
| Enumerant | Definition | Value |
|---|---|---|
| SE_SHADMETH_NONE | Non-illuminated shading. Pixel colour is not affected by either spot or infinite light sources. This is sometimes called Fixed shading, since pixel colours are fixed and do not change at render-time. |
1 |
| SE_SHADMETH_FLAT | Polygon Face Normal is used when calculating illumination of geometry. |
2 |
| SE_SHADMETH_INTERPOLATED_COLOUR | Vertex normals and light sources are taken into account when calculating illumination of a geometry attribute (a.k.a. Gouraud Lit). |
3 |
| SE_SHADMETH_INTERPOLATED_NORMAL | Vertex normals are interpolated as part of the illumination algorithm (a.k.a. Phong). |
