A program that runs on your graphics card, instead of your CPU. Traditional shaders are called "shaders" because they were originally used for texturemaps - that is, like a filter you could run on texture maps.

The later invention was vertex-shaders, programs that were run on the GPU to actually deform the model itself. You can even use them for skeletal animations - you feed the GPU the undeformed model and bone and weighting info, and then you feed the shader your bone-positions, and the shader program handles posing the vertices of the model according to the bone-positions.

That's similar to what we have here - a fish waggling its tail is a simple algorithm - pretty much a sine wave. That makes it ideal for a vertex shader.

Im thinking zerg breathing building animations.

This would be cool.

That's really badass!

hmm it looks nice

i like the tree, that was kinda impressive.

I love the swaying tree, awesome work!

All the props go to jK on this one, I just slapped his shader on my tree model.

So what is the effect of this on fps?

Assuming you have a decent video card, probably very little. The FPS bottleneck is almost always the CPU load due to large games with many units.

I liked.

...Let's get this thread back on track.

when I spawn an angelshark, everything below the water line fails to show up. This is with bumpwater and shadows disabled. Upon enabling shadows, the entire map goes into crazy day-glo colors. zooming out far enough alleviates the problem. Units are unaffected. I can see the shark below the waterline with shadows enabled.

For me, I lose all terrain rendering when shadows are enabled, but works fine when I have them off. 8800gt

IIRC shadows were a hackjob we peer pressured SJ into writing far too quickly. That they break things should surprise nobody.

What does all this have to do with:

A. jK's cool shark.
B. jK's even cooler attempt to build a generic material API.
C. Beherith's awesome vertex-shader animated trees?

Please remove all this useless derail, this was a good thread.

I am in agreement. Somebody, please respond to http://springrts.com/phpbb/viewtopic.ph ... 89#p406489

should be an option to put it on grass too, or if you wanna get real fancy, have the map do it based on current wind speed.

anyway thats why i never do skyboxes - no animation. no pretty screenshots, but im an animation whore. static skyboxes are so halflife 1.

A new grass shader in general would be very nice, Spring grass looks incredibly dated; It looks better with it turned off.

"account suspended"

...

send the shark animation pls, maybe use jobjol?
