Hi Peter,
I have utilized this feature directly in Maya Python.
and I am able to find out whether two objects colliding or not.
Except for polyCubes, It is working for all other objects and complicated
shapes also
Some times it is working for polyCubes also.
we have to use:
xform (firstObj, q=1, ws=1, bb=1) -------> It yields 6 digits -------->
[f_minX, f_minY, f_minZ, f_maxX, f_maxY, f_maxZ] # bb yields
bounding box information
xform (secondObj, q=1, ws=1, bb=1) -------> It yields 6 digits -------->
[s_minX, s_minY, s_minZ, s_maxX, s_maxY, s_maxZ]
collideCheck =[]
for fx in range(f_minX, f_maxX):
if (fx> s_minX) and (fx<s_maxX):
collideCheck.append(True)
break
--do-- for yRange
--do-- for zRange
if collideCheck == [True, True, True]
print 'Objects are colliding'
else:
print 'Not colliding'
Try this..
