cxErrorCode cxPickHitConeGet( cxPick *pick, int n, long *part)
integer function cxPickHitConeGet(pick,n,part) integer pick integer n integer part
- Pick data structure to interrogate.
- Index of hit in pick structure.
- Part of the cone intersected.
Side = 0x01 Bottom = 0x02 All = 0x03The function returns cx_err_none on success. A non-zero value is returned in case of an error. This will usually be because the hit is not of the proper object type.
The user can tell the function not to get information on a particular field by passing a NULL pointer value. You need not create dummy variables in the calling routine which calls cxPickHitConeGet, because the request is simply ignored when the pointer comes in NULL.
