In Topic: Getting bounding box of convex polyhedron without the points?

I think the standard approach is to have a really large "world cube" as the initial shape and clip it against the planes. This is the approach in most papers I've read and the one I'm using. I am however using a plane based representation for all the actual operations, and only compute points for rendering since this allows me to have 100% robust CSG operations.

So, it seems to me that it would at least be useful to modify Forward+ by splitting each tile frustum into chunks along the depth.

In Topic: OpenGL supporting libs

There is no reason not to use GLM, it's very good and it is made to go with OpenGL.

One good reason not to use GLM is that Eigen is much more versatile and suitable for more than simple graphics calculations :)

GLM doesn't have any of the advanced features that Eigen has and mixing different math libraries is messy as hell.

"In this paper we present a new simplification algorithm, which computes a piece-wise linear mapping between the original surface and the simplified surface"


Some images from an old implementation I did:



Left: High poly

Middle: Low poly

Right: High poly geometry mapped onto low-poly mesh


Any property can be transferred from the high poly version.

I'm on a ketogenic diet, so I eat almost no carbohydrates at all. No negative side effects as far as I can tell :)
