Rounding problem

[ssloy]

What is the range of your tex coordinates? What does it mean - broken? Can you provide any image?

We use the same model file. When i keep it as Vec3i the image is produced as https://imgur.com/a/s48qDmv. When i debug it, i see so many texture coordinates are rounded 1 or zero. Then i calculate uvP.x1024 and uvP.y1024. The result is as the link.

In my code the texture coordinates vary between 0 and 1024 (actually, the image size). If you interpolate the original tex coords (those between 0 and 1), then yes, you need to use floating point.
