Purpose

The SoGVRShaderInclude allows for adding of custom shader code in the header of the GVR shader pipeline.

Usage

Connect the module before the SoGVRVolumeRenderer module in the scene graph and implement the custom shader code to be included in the header. The included shader header can be used in a SoGVRShaderFunction. For that, the identifier string has to be declared in the parameter field of the SoGVRShaderFunction module with the keyword include.

Tips

Implement often used custom functionality using this module.
