NAME

cxPickHitConeGet - get detail information about a pick hit on a cone
#include <cx/Pick.h>

cxErrorCode cxPickHitConeGet( cxPick *pick, int n, long *part)
integer function cxPickHitConeGet(pick,n,part)
integer pick
integer n
integer part
pick
Pick data structure to interrogate.
n
Index of hit in pick structure.
part
Part of the cone intersected.
The return value for this function is an integer error code enumeration. This function extracts detail hit information about a cone. The part of the cone is returned in part. The part information is a set of bit flags identical to those used in Inventor:
  Side = 0x01
  Bottom = 0x02
  All = 0x03
The 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.
