python script to use with 'make Live' heeelelllppp...

[sam williams]

Hey there,

You know when you make a surface 'live' and then you select and move another nearby object and it instantly snaps to the closest point on the 'live' surface...

well i basically want to do this with a script. so it selects the object near the 'live' surface and basically moves its position fractionally so it will snap to the 'live' surface. How come it works when i grab the central pivot of the move control, but not when i use the cmds.move() command?

is this possible with scripting?

If anyone can help me with this i would be very grateful,

thanks,
Sam

(the end result im trying to achieve is to cycle through points on a curve and snap them one at a time to the closest point on a nearby mesh)

Take a look at the MMeshIntersetor, or the MFnMesh (getClosestPoint) in the Maya API. You can search for the closest point on the mesh to a given point.

You need to dive into the api though.

If your intent on cycling through vertices and snapping them using Python, then this probably won't help much. But if you're looking to snap a curve onto a mesh via their closest locations and you happen to be running Maya 2015, then there's an option under Edit Mesh called "Project Curve on Mesh" that could do what you want.

Thanks Marcus,
Does this tool, know automatically the closest point on the mesh to project onto?.

It seams you have to tell it where to hit the mesh, based on a selected axis or from the perspective of the camera. I basically need each point on the curve to know which part of the mesh is mathematically closest and then move to this location. I tried the project curve on mesh in maya 2014, i dont know if there is an updated 'proximity' feature in 2015..

cheers,
Sam

Hi Sam,

That's a good point, you may be right, it might not be possible with that command alone. However, if you're up for getting a bit creative, there's one more approach I could suggest.

1. Loft your curve

2. Convert to polygons

3. Clear history of polygons

4. Wrap your original curve to the converted loft

5. Use the transfer attributes tool to snap the converted loft onto your target.

6. Clear history of curve

7. Delete converted loft

Clearly a bit involved, but when done via a script should be quite seamless, although I suspect that if I were more comfortable with the API and its raycasting methods I'd probably suggest that for you instead. :) Let me know how it goes!
