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¶: Enable the opaque input geometry. The effects are applied to this geometry.

Enable Transparent Geometry¶

name: enableTransparentGeometry, type: Bool, default: FALSE¶: Enabled rendering of the transparent input geometry using depth peeling or blended average.

Enable Additional Geometry¶

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

Enable Effects¶

name: enableEffects, type: Bool, default: FALSE¶: Enables additional input effects, see effects.

Enable Late Effects¶

name: enableLateEffects, type: Bool, default: FALSE¶: Enables late effects, see lateEffects.

Mode¶

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

Values:

Title	Name	Description
Dual Depth Peeling	DualDepthPeeling	Dual depth peeling render 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¶: The number of layers, used when depth peeling is enabled.

Antialiasing¶

name: antiAliasing, type: Enum, default: FXAA¶: The anti-aliasing mode that is chosen. 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.
