Goo is a nice Shadertoy demo that shows a kind of slime. I couldn’t resist to convert this multipass demo to GeeXLab and to add some widgets to tweak the different colors: albedo, ambient and sky colors.
The demo is available HERE (zip file). Unzip the archive where you want and load the demo.xml into GeeXLab. That’s all. The latest GeeXLab can be downloaded from THIS PAGE. This is an OpenGL 3.2 demo and it should run on Windows, Linux and macOS platforms (only tested on Windows).
With a GeForce GTX 1080 + Win10 64-bit + latest GeForce 391.24 driver, the demo runs at 79FPS (default resolution: 1280×720).
The demo is also available in the full code sample pack (gl-32/shadertoy-multipass/gl32-goo/ folder).
