My new node based image generator

Node based image generator 1 from johan holwerda on Vimeo.

This is an application I am working on in my free time. I will be using it to create realtime 3d graphics with animated parameters.
In the video it shows the creation of a simple patch (animating 1 parameter of subblue’s distance estimator shader, and some camera rotation). Patches can be nested and saved. The signals between the modules can be of a wide variety of datatypes (texture, float, matrix, etc) and every parameter can be linked to every output (datatypes are automatically converted). I hope the main logic of the application will be done in a few months, so I can start writing modules and generating output.
Build with c# and xna.


  1. Looks awesome already. Any chance to see the source/insights into the dev process?

  2. Hi, I am sorry for the late rely. At the moment the core of the program is not yet how I want it, so I am still throwing things around, refactoring, cleaning up etc. I would rather show you the code when the basics are done, and I am writing modules.
