GPU video

i dont know if oyu can do this already but wouldnt it be cool if you could play a video with GPU? like a youtube video or something.^_^

What's the use? You will be able to draw animated textures along with regular textures eventually, but whats the use

What's the use in wire computing in general? I dunno, I think it would be pretty cool. I've tried to make videos in Gmod before but rangers were too slow. I haven't tried out hi-speed rangers yet, but they weren't around when I tried. I only used one ranger too.

Suffered from the digiscreen having low res too, but speed was the main problem.

The videos would have no sound.

You could use it to see behind you in various vehicles. Or to monitor a stationary point. Doesn't have to be a blooper reel of animals doing hilarious things with boing sounds and such.
You could (theoeretically) make sounds (music for example) using sound emitters with sine, saw and square. More detailed if they had high-speed links.
I've tried making a CPU audio sequencer using a keyboard and sound emitter, but I lost interest partway through figuring out how pitchrelative works.

The basic idea was to record the keyboard input to RAM at a constant rate and just play it back to some sound emitters. If anybody wants to give it a go, feel free. I've pretty much abandoned it

@ The original post, somebody is working on a GPU camera that uses some sort of wizardry to allow pixels to be drawn. A video camera wouldn't be much of a modification to that, but the question is if it'll be fast enough.

That's what the RT camera is for

I get what you're saying though. I just really don't see this being too terribly useful. We can already use the RT camera for "video" of in-game stuff, and the GPU can display animated graphics. The only other purpose I can think of for playing video in-game, would be to just mess around and play youtube videos or something. Perhaps even cutscenes in games made with the GPU... but that's a stretch.

Well there's also overlays and whatnot. But mostly it'd be a gimmick.

That would be me.

But alas, I gave up on the code so here it is, my final un-finished version with the high-speed camera.

That's a shame. How did you get the high speed ranger to interact with GPU? I vaguely remember hearing how, something about flushing GPU memory. Does that make its membus work?

**Hitman271** · 11-20-2008

I didn't flush the gpu's memory at any point with that. The cpu got all the data and then the cpu had its membus go directly to the gpu. This eliminated the need for the gpu even have any real outside connections
