comment Bilinear filter in repeating texture, HLSL
If I do that I'll lose texture repeat, surely? To be clear, I want repeating textures, but I don't want filtering over the edges.

comment Shimmering, scrolling/panning a texture
Thanks Gregory. I don't have mipmaps and there would be some complexity involved in creating them. One thing I did notice is that because I was using random noise (unstructured), the eye had nothing to track when the screen scrolled. When I changed it to Perlin noise, even at quite high frequency, the scrolling looked perfectly smooth. So I think I might have discovered a psychological effect as well as a compute graphics one. My actual data will be semi-structured, i.e. there will be features in it, so I'm optimistic I won't need mips.

comment Shimmering, scrolling/panning a texture
The luminance texture is sampled with linear, which is fine as the palette is sampled POINT. It shimmers regardless as I've tried it every which way. The issue I think is the sub-pixel shift during the scroll. What I want is a nice smooth scrolling/panning surface. I'm thinking perhaps I should generate some geometry (2 quads) and move those instead of shifting texture coordinates, swapping them over when one scrolls off screen. But I hoped there might be a filtering technique to help with the scrolling as this is the simpler method.

OK, not sure whether to delete this question as unbelievably stupid or ask you to add that as the answer so I can give it a cookie. It now works as I changed it to 0. I need to pay attention to what I copy and paste from the internet :p. Thanks János

In the vertex shader? No, the only place the sampler is used is in the pixel shader. I think I see what you're getting at here... that's for vertex texture fetch isn't it. Hmmmm...

revised Light following me around the room. Something is wrong with my shader!
Grammar correction.

comment Will there be any more books in the Game Programming Gems series?
So much of this stuff became GPU Gems, didn't it? I love these books and have a huge stack of them at home.

comment FFMPEG Opengl video rendering
Have you looked at gStreamer libraries at all? I use them at work for video streaming/pipeline work. Take some getting the hang of, but they're quite comprehensive (use FFMPEG in places too).

Didn't actually know this existed. I'll look at it. Thanks :)
