Hi,

I need bitwise operations in a shader.
But I learned that this is not possible with d3d9.
Is there a way to emulate this behaviour.

For Example:
int val = anotherVal & 0xffffffff;

Maybe the following blog entry is a solution for you:

Wow, this was fast
Thank you for the link.
I need to study it and try some things, before I realy understand it, but it is a much better solution than what came up on my previous google searches.

It's basically a lookup table for all the binary operators where the result of one operator is stored in one channel of the texture.
