WebMay 21, 2015 · One big difference between WebGL GLSL and many articles found about shaders on the internet is there's no fixed function pipeline in OpenGL ES 2.0 and therefore no fixed function pipeline in WebGL. The fixed function pipeline is left over from OpenGL 1.0 where you'd use commands like glLight and glVertex and glNormal. WebThe most basic workflow is as follows: Create a file with a custom GLSL function (the Shader) using RV’s extended GLSL language. Create a GTO node definition file which references the Shader file. Test and adjust the shader/node as necessary. Place the node definition and shader in the RV_SUPPORT_PATH under the Nodes directory for use by ... olivier bourau gevrey chambertin
