I've come across a texture problem in my 2D tile game in 3D.
I know about the texel pixel issues when trying to create a 2D game
using 3D quads described here:
Basically I can render my tiles perfectly but when I move the camera,
(by transforming the view matrix) sometimes a border line of my tiles
textures will stretch to two pixels or vanish completely.
I've taken the code out and put it into a very simple program to
demonstrate my problem easily.
Heres the source code: http://www.yqcomputer.com/
Someone suggested I clamp the textures - I did this and it removed pink
lines I was getting but the lines expanding and disspearing remained.
Here's a screen shot of what it looks like at the start:
And after moving the camera down a bit:
My wild guess is that's it something to do with the random manner in
which I've set the camera up. Can some one set me straight, please!
