Shadertoy Demopack

[JeGX]

Here is a new demopack for GeeXLab. The pack contains all Shadertoy demos from the full code sample pack: old demos (OpenGL 2.1 in gl-21-xxxx/ folders) and recent demos (OpenGL 3.2 in gl-32-xxxx/ folders). There is also a special folder for Raspberry Pi (gl-21-shadertoy-rpi/).

The latest version of the shadertoy demopack can be downloaded from this link:

- Shadertoy Demopack DOWNLOAD


You can download the latest GeeXLab from this page:

- GeeXLab DOWNLOADs


Usage:
- unzip the demopack where you want.
- drag and drop a demo (.xml file) into GeeXLab.

Tests:

- Resolution: 800x480
- GPU: GeForce GTX 1080 + 417.71 + Win10 64-bit 1809

NUM is a constant that can be changed in the pixel shader source code (line 75 in the XML demo file).

- NUM = 256 => 4500 FPS
- NUM = 512 => 3500 FPS
- NUM = 1024 => 2900 FPS
- NUM = 2048 => 2900 FPS
- NUM = 3072 => 2800 FPS
- NUM = 4080 => 2800 FPS

- NUM = 4096 => compiler crash
  => Internal error: assembly compile error for fragment shader at offset 783:
     line 27, column 12:  error: size of temp array must be integer

- NUM = 8192  => 0(47) : error C5041: cannot locate suitable resource to bind variable "data". Possibly large array.



For NUM=4096, the NVIDIA GLSL compiler gave me:
