const SbVec4f & SoTextureCoordinate3Element::get | ( | const SbVec3f & | point, |
const SbVec3f & | normal, | ||
int | unit = 0 |
||
) | 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 SbVec3f & SoTextureCoordinate3Element::get3 | ( | int | index, |
int | unit = 0 |
||
) | const |
Returns the indexed coordinate from an element as a 3- or 4-vector, converting if necessary.
const SbVec4f & SoTextureCoordinate3Element::get4 | ( | int | index, |
int | unit = 0 |
||
) | const |
|
static |
Returns the stack id for this element.
|
static |
Returns the type identifier for this class.
|
static |
Returns the top (current) instance of the element in the state.
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.
int32_t SoTextureCoordinate3Element::getNum | ( | int | unit = 0 | ) | const |
Returns the number of coordinate points in an instance.
|
virtual |
Returns code indicating what has been set in state/element.
