[Solved] Problems getting vertex indexes from face id


Recommended Posts

Hi all, sorry if this may seem to be a stupid question but i'm struggling about that... I'm trying to raise only y coordinates of the vertices of a mesh face when I click on it.

I retrieve the face id: faceID = window.engine.scenes[0].pick(offsetX, offsetY).faceId;

Then I get indices:  var indices_array = mesh.getIndices();

I get vertices positions array: var arr = mesh.getVerticesData(BABYLON.VertexBuffer.PositionKind);

But something goes wrong when I try to increment y coordinates of the three vertices:


mesh.updateVerticesData(BABYLON.VertexBuffer.PositionKind, arr,true,true);


It seems that with those formulas i'm picking the wrong vertices from face ids... What's wrong there?

Tnx, cheers
