In Topic: floating point texture, heightmap

So I guess graphics cards (still) only support blending on 16bit floating point textures, GL_R32F changed to GL_R16F. Works fine.

Whats interesting is that if I glColo4f(1,1,1,.1f); my brush, then it draw the initial brush very softly (very small height change on my terrain) and then the second time I blend it, it blows up again pure red with black holes in it. Does openGL have a problem with blending floating point textures?

Right, right now I don't even list it. I was just wondering as I learn it, and being that I already knew how to code, when I would be good at it. I wasn't sure how much was out there to know.

Also depends on how big the object is on screen. If you render a million triangles that are drawing to 1/50th of the screen, tons of pixels will be drawn too and will incur very bad performance.

Yes. postive z (0,0,1) is pointing from your montiro towards your head.  (0,0,-1) is from head to monitor. So you start looking down -1.
