- get detail information about a pick hit on a cone
integer function cxPickHitConeGet(pick,n,part)
Pick data structure to interrogate.
Index of hit in pick structure.
Part of the cone intersected.
FUNCTION RETURN VALUE
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.
