void Show_Text_Path | ( | float * | x, | |
float * | y, | |||
float * | z | |||
) |
Returns the text path that has been set on the currrently open segment.
x | X-coordinate of the directional vector that describes the text path. | |
y | Y-coordinate of the directional vector that describes the text path. | |
z | Z-coordinate of the directional vector that describes the text path. |
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_Text_Path 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_Text_Path | ( | const char * | segment, | |
float * | x, | |||
float * | y, | |||
float * | z | |||
) |
Similar to Show_Text_Path() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
x | X-coordinate of the directional vector that describes the text path. | |
y | Y-coordinate of the directional vector that describes the text path. | |
z | Z-coordinate of the directional vector that describes the text path. |
void Show_Net_Text_Path | ( | float * | x, | |
float * | y, | |||
float * | z | |||
) |
Similar to Show_Text_Path(), but returns the net effective setting rather than the local one.
x | X-coordinate of the directional vector that describes the text path. | |
y | Y-coordinate of the directional vector that describes the text path. | |
z | Z-coordinate of the directional vector that describes the text path. |
void PShow_Net_Text_Path | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
float * | x, | |||
float * | y, | |||
float * | z | |||
) |
Similar to Show_Net_Text_Path(), but returns the net effective setting along a discrete segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
x | X-coordinate of the directional vector that describes the text path. | |
y | Y-coordinate of the directional vector that describes the text path. | |
z | Z-coordinate of the directional vector that describes the text path. |
void QShow_Net_Text_Path | ( | const char * | segment, | |

segment | The segment to query. | |
x | X-coordinate of the directional vector that describes the text path. | |
y | Y-coordinate of the directional vector that describes the text path. | |
