void Show_Modelling_Matrix | ( | float * | matrix | ) |
Returns the modelling matrix that has been set on the currently open segment.
matrix | Curent transformation matrix. 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_Modelling_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_Modelling_Matrix | ( | const char * | segment, | |
float * | matrix | |||
) |
Similar to Show_Modelling_Matrix() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
matrix | Curent transformation matrix. Passed by reference. Returned to user. |
void Show_Net_Modelling_Matrix | ( | float * | matrix | ) |
Similar to Show_Modelling_Matrix(), but returns the net effective value rather than the local one.
matrix | Curent transformation matrix. Passed by reference. Returned to user. |
void PShow_Net_Modelling_Matrix | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
float * | matrix | |||
) |
Similar to Show_Modelling_Matrix(), but returns the net effective value along a discrete segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
matrix | Curent transformation matrix. Passed by reference. Returned to user. |
void QShow_Net_Modelling_Matrix | ( | const char * | segment, | |
float * | matrix | |||
) |
Similar to Show_Net_Modelling_Matrix() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
matrix | Curent transformation matrix. Passed by reference. Returned to user. |
