PostEffectRenderer¶

MacroModule¶

genre	`View3D`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
definition	viewers.def
keywords	`antialiasing`, `transparency`

Purpose¶

The PostEffectRenderer offers a typical configuration of the SoPostEffectRenderer, like View2D does for SoView2D.

It provides rendering of opaque,transparent and additional geometries with anti-aliasing. The additional geometry is typically used for Volume Rendering on top of opaque geometry.

Usage¶

Enabled the inputs that you need and connect the geometry scenes to it.

Input Fields¶

opaqueGeometry¶

name: opaqueGeometry, type: SoNode¶: Enables the main opaque geometry input. The effects are applied to this rendering, except for the anti-aliasing which is applied to all inputs.

effects (hidden)¶

name: effects, type: SoNode¶: This enables adding additional effects to the rendering. Have a look at the GLSL Post-Processing Effect Framework to see when effects are available.

transparentGeometry (hidden)¶

name: transparentGeometry, type: SoNode¶: This input offers the correct rendering of transparent geometry, using depth peeling or blended average rendering. Effects are not applied to this input, except for the anti-aliasing.

additionalGeometry (hidden)¶

name: additionalGeometry, type: SoNode¶

This input is typically used to overlay Volume Rendering (using SoGVRVolumeRenderer) onto the opaque and transparent rendering.

This additional scene is rendered on top of the opaque + transparent inputs, no effects are applied except for anti-aliasing.

lateEffects (hidden)¶

name: lateEffects, type: SoNode¶: These late effects are applied after all geometry is rendered, but before the anti-aliasing. Have a look at the GLSL Post-Processing Effect Framework to see when effects are available.

Output Fields¶

outScene¶

name: outScene, type: SoNode¶: The scene that can be placed into a viewer.

Parameter Fields¶

Field Index¶

`Ambient Occlusion`: `Bool`	`End`: `Color`
`Antialiasing`: `Enum`	`Layers`: `Integer`
`Background`: `Bool`	`Mode`: `Enum`
`Enable Additional Geometry`: `Bool`	`Start`: `Color`
`Enable Effects`: `Bool`
`Enable Late Effects`: `Bool`
`Enable Opaque Geometry`: `Bool`
`Enable Transparent Geometry`: `Bool`

Visible Fields¶

Enable Opaque Geometry¶

name: enableOpaqueGeometry, type: Bool, default: TRUE¶: If checked, opaque input geometry is enabled. The effects are applied to this geometry.

Enable Transparent Geometry¶

name: enableTransparentGeometry, type: Bool, default: FALSE¶: If checked, rendering of the transparent input geometry is enabled using depth-peeling or blended average.

Enable Additional Geometry¶

name: enableAdditionalGeometry, type: Bool, default: FALSE¶

Enable Effects¶

name: enableEffects, type: Bool, default: FALSE¶: If checked, additional input effects are enabled; see effects.

Enable Late Effects¶

name: enableLateEffects, type: Bool, default: FALSE¶: If checked, late effects are enabled; see lateEffects.

Mode¶

name: transparencyMode, type: Enum, default: DualDepthPeeling¶: Defines the transparency mode.

Values:

Title	Name	Description
Dual Depth Peeling	DualDepthPeeling	Dual depth-peeling renders transparencies in the correct order, peeling `Layers` / 2 from the front and from the back.
Depth Peeling	DepthPeeling	Depth-peeling renders transparencies in the correct order, peeling `Layers` from the front.
Blended Average	BlendedAverage	Blended average offers a fast transparency rendering mode; see `SoPostEffectTransparentGeometry` for details.
Linked List	LinkedList
KBuffer	KBuffer

Layers¶

name: transparencyLayers, type: Integer, default: 8, minimum: 1, maximum: 64¶: Sets the number of layers used if depth-peeling is enabled.

Antialiasing¶

name: antiAliasing, type: Enum, default: FXAA¶

Defines the anti-aliasing mode. If anti-aliasing is enabled, enabling sample buffers/MSAA on the viewers or remote rendering module is not needed, since the anti-aliasing is done as a post effect.

For details, have a look at the SoPostEffectAntiAliasing module.
