Learning GLSL (OpenGL Shader Language) is a little harder to me, but if I can create shader like Unreal Engine 4's material design tool? Let's play with Shader on OpenFrameworks. I using mruby and OpenFrameworks to create a scriptable GLSL generator to create shader. By the power of Ruby DSL, the shader generate becomes very fun and simplely. 蒼時弦也, @elct9620 A Web Developer focus on Interaction Design, and love Game, Animation and Comic.
