hello internet....I have been working on this collision deformer node for a
long time and still cant get it right....I have done many research and even
ask people for the reference code but IT JUST WONT WORKS!!!!!!!!...
the big idea for my collision deformer is
first do a intersection test between the collider bounding box and deformer
bounding box
if intersected, check if the collider bounding box contain the deformer
vertex( in world coordinate)...
if contained, do allintersection test for the vertex to see if it is
inside the the collider mesh or not , using
(if (hitPoints.length() % 2 == 1))
and then do the deformation and save the point to the finalpnts array( used
later to set all positions )
for debugging purpose I asked the maya to print out the collision point
index, and it works fine, but the deformation algorithm I have in that same
if loop just wont works........I have no idea why and really ran out of
idea..please help....
here is the test result

here is the c++ code I have.
