I'm not sure but I seem to recall that this was implemented a bit late for
the IMD team and that this should be covered in a tech note or elsewhere.
Sorry my memory is fuzzy on those particulars, I'll look into this and make
sure what I'm about to write is noted somewhere other than buried in a
Dir3d-l archive. First, your old syntax will behave as it always has, so no
worries there. But if you want to go with the newer snazzy way of doing
things:
-- build a list of models among which to cast
tModels = [ modelA, modelB, ... ]
-- build an argument list to pass to the modelsUnderRay call
tArgList = [#maxNumberOfModels: 10, \
#levelOfDetail: #simple, \
#modelList: tModels, \
#maxDistance: 50]
-- cast the ray
tResult = 3dMember.modelsUnderRay(location,direction,tArgList)
All entries in the argument list are optional and can be provided or not. If
you specify a list of models then the list should be composed of
_model_object_references_, do not use just the string names! If a model's
bounding sphere is within the range maxDistance from your raycasting source
point then the model will be checked against the raycast, if its bounding
sphere is greater than maxDistance away it will not.
Enjoy.
Cheers,
