void | Show_Net_Normal (float *x, float *y, float *z) |
void Show_Normal | ( | float * | x, | |
float * | y, | |||
float * | z | |||
) |
Returns the normal for the currently open vertex or face.
x | X-coordinate of the current normal of a face, edge, or vertex. | |
y | Y-coordinate of the current normal of a face, edge, or vertex. | |
z | Z-coordinate of the current normal of a face, edge, or vertex. |
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_Normal 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 Show_Net_Normal | ( | float * | x, | |
float * | y, | |||
float * | z | |||
) |
Similar to Show_Normal(), but returns the net effective normal rather than the local one.
x | X-coordinate of the current normal of a face, edge, or vertex. | |
y | Y-coordinate of the current normal of a face, edge, or vertex. | |
z | Z-coordinate of the current normal of a face, edge, or vertex. |
