SoPostEffectMainGeometry

InventorModule

author	MeVis Medical Solutions AG
package	MeVisLab/Standard
dll	SoRenderers
definition	SoRenderers.def

Purpose

The SoPostEffectMainGeometry module renders the given input scene into buffers for the SoPostEffectRenderer module.

By default, it renders to the “colorBuffer” and “depthBuffer”. If other effects require normals or emissive colors, it also renders to “normalBuffer” and “emissiveBuffer”.

This module should be one of the first in the scene, as it provides the geometry onto which the effects are applied.

It can also write extra data to a so called “auxiliaryBuffer”. If enabled via Write Auxiliary Buffer, a custom SoShaderPipelineFunction can write auxiliary data to the vec4 state “auxOutput” and this will be written to the aux buffer.

This module makes use of the SoShaderPipeline, this means that fixed-function texturing in the scene below the module will have limited functionality and will require writing your own SoShaderPipelineFunction to implement automatic texture coordinate generation. If you want to change the settings of the SoShaderPipeline that is used in the scene below, you can place an extra SoShaderPipeline into the scene, this will allow you to customize the used shader.
