hi there! suppose i drew a cube, with a vertex shader outputing the world vertex positions to a texcoord (so that the pixel shader can pick the interpolated values up). I noticed that the interpolated values are rather "distorted", as in if u move the camera(spherical) around. considering that they are just simple world coordinates, is there a way around this problem?? thk!

ah ok!
erm... i realized what was wrong
i went to do a perspective divide (divide by w) in the vertexshader, removing it helps entirely now.

i was doing it for obtaining correct depth value[0,1] in HLSL,
think i kinda accidentally extended this operation to the final xy coords.

cheers!
