Can anyone post a quick sample of how to use the new primitives? I’ve loaded models and animations with the away3d 4 (dev section on github), but I can’t for the life of me figure out how to just add simple primitives now. I keep getting an error from flash builder stating “1067: Implicit coercion of a value of type away3d.primitives:SphereGeometry to an unrelated type away3d.containers:ObjectContainer3D”

I just want some sample code for the new primitives is all :D

I finally found what I was looking for. I was talking about the new primitives like planegeometry.as and spheregeometry.as ... here is what I found. The capsule primitive has changed since the version you are using. Here is an example I got after making this thread ...

_plane = new Mesh(new PlaneGeometry(1000, 1000, 2, 2, true), sphereMat);

It’s pretty simple, I just couldnt figure out the new syntax haha

Thanks, came here looking for any way to use the geometry.
