Computes texture coordinates for geometry automatically based on vertex position and/or normal.
This can be used to implement reflection and/or refraction maps, for instance to make shiny surfaces, as well as other special effects such as projective texturing.
const RenderAttrib addStage | ( | TextureStage | stage, |
TexGenAttrib::Mode | mode | ||
) |
Returns a new TexGenAttrib just like this one, with the indicated generation mode for the given stage.
If this stage already exists, its mode is replaced.
const RenderAttrib addStage | ( | TextureStage | stage, |
TexGenAttrib::Mode | mode, | ||
const LTexCoord3 | constant_value | ||
) |
Returns a new TexGenAttrib just like this one, with the indicated generation mode for the given stage.
If this stage already exists, its mode is replaced.
This variant also accepts constant_value, which is only meaningful if mode is M_constant.
