void | DShow_Distant_Light (HC_KEY key, float *di, float *dj, float *dk) |
void Show_Distant_Light | ( | HC_KEY | key, | |
float * | di, | |||
float * | dj, | |||
float * | dk | |||
) |
Returns the direction of a "distant light", as referenced by a key.
key | - Unique numeric identifier pointing to a distant light in the database. | |
di | - Direction, with respect to the origin, of the distant light in object space. Returned to user. Passed by reference always. | |
dj | - | |
dk | - |
The key for the distant light might come from Find_Contents() ( Begin_Contents_Search() ), or it might have been saved by your program when the distant light was created (via Insert_Distant_Light() ).
void DShow_Distant_Light | ( | HC_KEY | key, | |
float * | di, | |||
float * | dj, | |||
float * | dk | |||
) |
Similar to Show_Distant_Light(), but accepts and/or returns double-precision values. This command can only be used when the application source includes the HOOPS double-precision header, hcd.hs.
