Tutorial to start with COMPUTE SHADERS!

Hey all,
I was looking for some good resources and tutorials for compute shaders but they were hard to find.
Do you guys know any good book or any reference that I can learn more about compute shader.

I would appreciate a lot your help.

Thanks.

 

Hi,
I was also looking for that kind of resources and I found the channel Makin' stuff look good.
Here's a video on shader :

Very simple and easy to understand.

EDIT : Also, check this out :

No, @amirivala is asking specifically about compute shaders, not shaders in general:
https://docs.unity3d.com/Manual/ComputeShaders.html

I'm kind of curious about those too. They seem a bit mysterious.

 

Yes, some ppl will shine with dis-acknowlage

The first one taught me everything I know.

 

These are ok:

 

Hi!

(I just found this on the third page of a google research: http://unitylist.com/r/d17/tuto-compute-shader )


Well, for me, I red the attached word tutorials once I got the basics. They are quiet nicely explained, for I'm no shader pro at the moment.
Mind that they come from an older Unity version tho.

 

I wrote two tutorials about compute shaders. Each one has link to example project.

Here's easy one, about drawing a Mandelbrot fractal in GPU.

And here's complex one, about physics simulation on GPU.

Gif from the example project of the second tutorial.

 

A compute shader can draw pixel wise. That means, you can draw eg. an specified area out of a render texture into another texture.

+ The shader requires to be initialize with a simple call from c# before it can run the first time. (init address and variables)
+ You can compare the working behavior of a compute shader with for loop in c#.
+ It's possible to jump (after initializing) to a specified marker or address inside of the shader from c#. Means, you can call parts of a compute shader like a function in c#
+ The shader runs one time until you call it again. Means, it does not run permanently like a surf/frag shader and you have the complete control when it should run.

That's the ruff basics about.
Did I miss anything?

 

Hi!

Adding a recent reference that was helpful in my case,

If your had the choice of avoiding embarrassment or having correct information, which would you choose?
