GPU Berserker GLSL
In this section, we will have a quick look at how the GLSL works in PixelsWorld.
What is GLSL?
GLSL is an abbreviation of OpenGL Shader Language, which is supported by OpenGL, run on GPU.
How to learn it?
We recommend The book of shaders
Advantage of GPU render
If we treat the CPU as a supercar, the GPU should be more like a bus.
In the case we transport a few people, one or three, a supercar is adequate. (Handle single complicated calculation)
When it comes to thousands of people, a bus could be helpful. (Render thousands of data simultaneously)
Languages like C/C++, Java, Python, etc., are almost designed to run on CPU.
Languages like GLSL are designed for GPU.
When we want to render a picture. GPU distributes your code to many "workers" to repetitively calculate the result for each pixel.
If you want to learn more about GLSL, we recommend you to go to shadertoy.com, find some interesting arts, and make out why this works.
Before the GLSL is sent to OpenGL, PixelsWorld will combine pre-defined and post-defined codes to support features of Ae. If you are a beginner, you can ignore this section for the moment.
- PixelsWorld V3.0.0 use #version 330 core.
Here are pre-defined and post-defined codes.
