Detailed Description

Function Documentation

HC_BOOLEAN PShow_Net_Camera_Near_Limit ( int  keycount,
HC_KEY pathkeys,
float *  wlimit 
)

Populates the wlimit with the net effective near camera limit value along a path of segments specified by an array of HC_KEY's. Returns true if the near limit was set locally on this segment.

Parameters
keycount- size of the pathkeys array
pathkeys- The list of keys starting with the owning segment and following back to some desired segment.
wlimit- a parametric value from 0.0 at the camera to 1.0 at the target. Passed by reference. Returned to user.

DETAILS

As with all PShow_Net_* routines, pathkeys[0] represents the lowest (a.k.a the "most local" or "leaf"), and pathkeys[keycount-1] represents the highest segment. If the path is incomplete, missing segments are filled in if possible. Missing segments must be part of the same direct ancestry in order to be filled in. If the desired path contains an include link, the shortest unambiguous set of pathkeys would be [leaf, includelink, root], where includelink is the return value from Include_Segment().

By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key.
