[TUT] Simple PixelShaderTutorial for Dummies - 03/08/05 06:08

Hi,

i put a little tutorial online: PixelShaderTutorial1

It would be nice if some experts will have a look on if it is correct so far. Some code snippets to put online would be nice too.

Someone have a tip to correct the align of the alpha texture?

I like this tutorial, nice work

But I think you might want to explain more about the the process of programming a shader for the whole "Material" script insted of just the PixelShader script.

Ill love to see more shader tutorials from you Since I am a noob at shaders, your tutorial told me about starting out with shaders, nice work.

Good idea, i write my little knowledge with comments into the project-script.

Iīll will update it if i learn more.

@ShaderExperts:
1. Can anyone help how to lay a texture on top of each other. How can i align the alpha texture to the bottom of the bock?

2. I have experimented with texkill. Itīs a good thing to make a part of a block invisible. Have anyone an example for this?

It looks like the code is for DirectX 8.1 and it's in assembly.

Will this work for fixed-function pipeline? I mean, for fixed-function effects?

Very basic tutorial but my laptop doesn't have a support for pixel shader but it does have some kind of vertex shader support... The name of the video chip I have is ATI Radeon Mobility M6-P 16MB.

This is awesome, my advice, make some sort of wiki or interactive page, so everyone can come up with there own little tutorials like this!

Works with DX9 too.

As a noob i canīt answer this.

Do you ask if a tutorial came in the same style for vertexshader? After i have all learn to code pixelshader i need, i take a look on vertexshader. But may take some time.

I take a look if i can put this on the 3dgs wiki.

simply .. no it won't. As a rule anything in assembly is a pixel/vertex shader that runs only on a GPU.

Ah...I didn't mean to mention this but my laptop sucked... It's the ATI Radeon Mobility M6-P (7000) that I don't like the most.

Wouldn't fixed function effects run in GPU also?

Thanks.
