I have been playing with the lesson 10 tutorial, and I notice how the texture looks, amazingly crappy. I am just loading in various bmp''s into memory and using them for wall/ceiling/floor, I did them with GL_LINEAR and GL_LINEAR_MIP_NEAREST, but they still look to me, to be amazingly crappy. is it the bmp''s? i got the from 3dcafe.com under free textures, and just resized them to 256x256. Any clues? I am just maping the textures on with the texture coordinates as well, same way lionel-nehe show it done in tut 10. Just started with opengl as well about 3 weeks ago Moo@houston.rr.com

Anytime you enlarge an image the extrapolation will cause degradation in quality. Whether you do this in OpenGL or an art program, the same issue arrises.

A had a similiar issue.
The colors weren''t smooth, and it looked very bad
What I had to do is set the graphics to 32-bit.
You can do this in your application, or can be done in the OpenGL settings for your video card driver (I set it in the driver settings.) and then things were fine for me.



Hopefully that''ll fix it

If you want to have high quality textures also try to set 32bit internal texture format.
