DESCRIPTION

GhGL is a set of OpenGL shader authoring components for Grasshopper that display shader results in Rhino viewports with inputs defined by Grasshopper data. GhGL is currently only available for Windows Rhino 7 WIP. 

To Install, run the TestPackageManager command in Rhino. Select ghgl from the list and click the install button. Once installed, you will find the components “GL Mesh Shader” and “GL Shader” in the “preview” bar of Grasshopper.

This exercise is using Grasshopper version 1.0.0007
