Re: [pygame] Pixel Location in 3D Space?

[Knapp <magick.crow@xxxxxxxxx>]

Just take your X,Y and add a Z to it.

To move it about use a matrix transformation.

This site seems to have a good explanation of the math.

You can also do other movements with these matrices and add them together and do it all in one step.

I hope I am giving you the answer you are looking for.

Basically, yes. I have a polygon defined in the texture map (2d), and a
polygon defined in the model (3d). For each pixel in the texture map,
what would its 3D vertices be?
