GLSL Uniform Structures
Do you know that you can use data structures as uniform variables in GLSL?
How To Render a Reference Grid
GLSL Hacker has a handy object called a grid. A grid is more or less just a collection of lines but that info is not really important. You can use a grid as a reference object when there’s no ground plane in the scene.
A Simple Method to Render an Image
To render an image, we need an orthographic camera, a texture GPU program, a quad and the image (a texture).
How To Pass Variables to a GPU Program
In this article, we saw how to use a GPU program with GLSL Hacker. Now we’re going to see how we can pass information (variables) to a GPU program.
How to Use a GLSL Program
Let’s suppose you just found this cool GLSL program somewhere on the Net:
Vertex shader:
#version 120
void main()
{
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
}
Pixel shader:
#version 120
void main()
{
gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0);
}
Now, let’s suppose you want to test it with a mesh torus. The first thing to do is to create a XML node for the GLSL program in the main XML file.
GLSL Hacker Blog Launched
Around two years after its launch on Geeks3D, our favorite demotool has finally its own dedicated weblog.
