Brad,

How are the geometry and texture coordinates for your sphere generated? It
looks like you might be mapping the same pixel (s,t) coordinate to vertices
that are actually some distance apart. This might explain the effect you are
seeing. I'm assuming you've also played with the TextureAttributes and set
NICEST etc. to see if that has any effect.

Subject: Texturing Problem


Hi,

I am have a problem with how a texture is being mapped to my geometry.

I have created a geographically correct model of the world, generated
textured coordinates and applied a texture to it. The result looks
extremely pixelated, almost as if vertex shading is being used, where
the colors are being sampled from the texture.

I then created a Sphere primitive with the same radius as my earth model
and applied the same Appearance to it (including the same texture) and
it looks great.

I am pretty sure all my texture coords are correct as the texture is
being mapped to the correct part of my earth model (i.e. Australia
appears where Australia should, no wrapping etc.).

I have attached a screen shot of the two situations.

I have tried playing with various Appearance settings but I can't figure
out how to fix my problem.

If anybody can point me in the right direction that would be greatly
appreciated.

Cheers,

Brad
