Glue Mesh To Point CloudAuthor: Claude Vervoort
Compound that binds a mesh to a point cloud, suitable, for example, for jelly-like deformations. Binds each mesh point to four point cloud points for a reference frame. Useful in conjunction with Lagoa, but also with other types of point clouds like those generated by voxelization compounds.

The difference to the built-in advect compounds is that it doesn't emit a point cloud point at each mesh point and bind it - but looks for closest points in an existing point cloud and binds to those. See this (V1.0) and this video (V2.0) for usage details.

Glue Mesh To Point Cloud Compound

Post by claudevervoort » 06 Oct 2011, 12:08

Hi!

So I finally got it to work, a simple compound that 'glues' a mesh to a point cloud. To illustrate this, I've made a scene using Lagoa Jello to deform an artful model of mine ;)

I've attached the compound too if someone wants to experiment.

And now the improved version :) I'm no more using a single point but rather a set of 4 points in the target point cloud, allowing for a more precise deformation therefore requiring less points in the Lagoa Simulation.

I also attach the revisited compound.

Cheers for sharing!
It's good to have an alternative to the "closed source" advect mesh compound.

Thanks for looking at it!

rray, I don't think it is like Advect. When I looked at it, advect is creating a point per vertex and binding it. Those vertices would not therefore form a 3d grid and thus would not work very well in a simulation like the Jello. (In addition this compound can be used with any simulation, not just lagoa, although I have not found another example yet than the Jello :) ).

I see, thanks for the explanation.
Great compound & videos, too
*if you don't mind I'm going to use that last one as a thumbnail for Glue's entry at rray.de :D
