I want to measure the distance between the transform, or center, of a cube, and the "nearest point" on a sphere. I have set this up as I think it's supposed to be. I am not sure if my results are correct or not. The fact that I don't know what i am looking for may be the problem.
I have connected my sphereShape.outMesh to nearestPointOnMesh.inMesh
and the cube.transform to nearestPointOnMesh.inPosition
The output result I think I am looking for is nearestPointOnMesh.position, which gives me:
[(0.33543354272842407, 0.87489151954650879, 0.33543354272842407)]
In the scene I created a measure tool that measures from the cube center to where I assume would be the nearest point on the sphere mesh.
I *think* what the .position should give me is the displacement, in 3D units, between these two points. Am I right? So 0.87489151954650879 would be the displacement in Y between the points. Whereas if I measure the distance between my locators in Y (from the measure tool) I get approximately 0.300
What am I doing wrong, or misunderstanding?
import maya.cmds as mc
mc.createNode('nearestPointOnMesh', name = 'npom1')
mc.connectAttr('sgShape.outMesh', 'npom1.inMesh', f =True)
mc.connectAttr('cube.translate', 'npom1.inPosition', f =True)
mc.distanceDimension(sp= (0.5,1.25,0.5), ep= (0.25,.95,.25))
print('nearestPointOnMesh.position is: ' + str(mc.getAttr('npom1.position')))
Thanks for reading this!!!
