Скачать или смотреть Creating a basic glsl shader using a pull-based flow

Since I've started building visual programming systems, I have always used a push-based approach where a node triggers another node. This is much inspired by flow based programming. But since I want to build a generic visual programming system, I thought that is also important to support different systems.. basic statecharts I already support, but a pull-based system is not yet something that I had build with my system. Until now! .. so in this video you can see how I construct a flow that is used to construct a glsl fragment shader. Here the output node pulls in the data from the node's cominh before it in the flow, so working backwards through a flow.

Although it's not my goal to build a full product around this alone.. a lot better and much more extensive applications already exist for building shaders this way. But still helpful to look at my project from a different perspective, which leads to some refactoring, bug fixing, insights and inspiration.
