void Show_Texture_Matrix | ( | float * | matrix | ) |
Returns the transformation that has been set against all vertex parameters in the scope of the currently open segment.
matrix | A 4x4 matrix describing how textures are aplied to vertices. Passed by reference. Returned to user. |
When the value being passed back is a string, be sure you've declared your string variable to be long enough.
In C, "passed by reference" means that you have to allocate an appropriate variable, either statically or off the stack, and pass a pointer to that variable to the HOOPS routine. To generate a pointer to a variable C, you prefix the variable with a "&". In other languages you normally don't have to do anything different from usual.
The Show_Texture_Matrix routines will complain if they're called and the attribute is not actually set in the segment. Use Show_Existence() to avoid this, if necessary.
void QShow_Texture_Matrix | ( | const char * | segment, | |
float * | matrix | |||
) |
Similar to Show_Texture_Matrix() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
matrix | A 4x4 matrix describing how textures are aplied to vertices. Passed by reference. Returned to user. |
void Show_Net_Texture_Matrix | ( | float * | matrix | ) |
Similar to Show_Texture_Matrix(), but returns the net effective matrix instead of the local one.
matrix | A 4x4 matrix describing how textures are aplied to vertices. Passed by reference. Returned to user. |
void PShow_Net_Texture_Matrix | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
float * | matrix | |||
) |
Similar to Show_Net_Texture_Matrix(), but returns the net effective matrix along a discrete segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
matrix | A 4x4 matrix describing how textures are aplied to vertices. Passed by reference. Returned to user. |
void QShow_Net_Texture_Matrix | ( | const char * | segment, | |
float * | matrix | |||
) |
Similar to Show_Net_Texture_Matrix() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
matrix | A 4x4 matrix describing how textures are aplied to vertices. Passed by reference. Returned to user. |
