| const SbVec4f & SoTextureCoordinateElement::get | ( | const SbVec3f & | point, |
| const SbVec3f & | normal | ||
| ) | const |
Given point and normal, returns texture coordinate. (The r coordinate will be 0.0 and the q will be 1.0 until we get 3D texture coordinate functions.)
| const SbVec2f & SoTextureCoordinateElement::get2 | ( | int | index | ) | const |
| const SbVec4f & SoTextureCoordinateElement::get4 | ( | int | index | ) | const |
|
static |
The get routines are called on an instance because it is more efficient than calling a static method that looks up the element in the state for every coordinate.
|
inline |
Returns the number of coordinate points in an instance.
