Why does the mesh impostor only collides with spheres?


Recommended Posts

Why ?

var rawVerts = object.getVerticesData ? object.getVerticesData(BABYLON.VertexBuffer.PositionKind) : [];
var rawFaces = object.getIndices ? object.getIndices() : [];
BABYLON.Tools.Warn("MeshImpostor only collides against spheres.");
returnValue = new CANNON.Trimesh(rawVerts, rawFaces);

Even tho CannonJS supports mesh/plane collision ? :

  Demo : https://schteppe.github.io/cannon.js/demos/bunny.html

 Source : https://github.com/schteppe/cannon.js/blob/master/demos/bunny.html

            // ground plane
            var groundShape = new CANNON.Plane();
            var groundBody = new CANNON.Body({
                mass: 0,
                position: new CANNON.Vec3(0,0,-5)


Edit: Ok, I overlooked the fact that the Mesh impostor is infact a  Trimesh shape (https://schteppe.github.io/cannon.js/demos/trimesh.html). So can you add ConvexPolyhedron shapes in the next release please ?

Because of how aabb works, fastest method is to test with a circle (and simplest)..


your not not going to get any additions to physics unless you program it yourself, or wait for one of the power players to release a new physics engine.

MeshImpostor is, indeed, a TriMesh.

I can add a ConvexPolyhedron, but it might take a bit of time.

We had it already, BUT  it wasn't calculated correctly on our side, and people didn't really understand how to use it. I will add it to my todo list. Which is as long as the Israeli-Palestinian conflict.
