SoGVROptimizations¶

InventorModule¶

genre	`VolRendExtensions`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoGVR`
definition	soGVR.def
see also	`SoGVRVolumeRenderer`

Purpose¶

The SoGVROptimizations module allows for setting the optimization settings of the SoGVRVolumeRenderer. This is typically required when creating custom shaders to disable/enable optimizations depending on the shader requirements and for debugging of GVR optimizations (to see if an optimization is the reason for a problem).

Output Fields¶

self¶

name: self, type: SoNode¶: A node that should be put in front of the SoGVRVolumeRenderer

Parameter Fields¶

Field Index¶

Allow Empty Tag Images: Enum

Allow Specialized Per Tag Effect Shaders: Enum

Enabled: Bool

Handles Clip Planes In Shader: Enum

Requires Gradient Textures: Enum

Requires Gradients: Enum

Use LUTHistogram For Node Visibility Check: Enum

Visible Fields¶

Enabled¶

name: enabled, type: Bool, default: TRUE¶: If checked, the settings are enabled.

Requires Gradients¶

name: requiresGradients, type: Enum, default: GVR_AUTO¶: Defines whether gradients are needed.

Requires Gradient Textures¶

name: requiresGradientTextures, type: Enum, default: GVR_AUTO¶: Defines whether a gradient texture is needed.

Values:

Title	Name
Auto	GVR_AUTO
On	GVR_ON
Off	GVR_OFF

Handles Clip Planes In Shader¶

name: handlesClipPlanesInShader, type: Enum, default: GVR_AUTO¶: Defines whether the shader handles the clip planes.

Use LUTHistogram For Node Visibility Check¶

name: useLUTHistogramForNodeVisibilityCheck, type: Enum, default: GVR_AUTO¶: Defines the visibility checking; this depends on the LUT min/max and histogram.

Allow Empty Tag Images¶

name: allowEmptyTagImages, type: Enum, default: GVR_AUTO¶: Defines whether empty tag volume octree nodes are allowed.

Allow Specialized Per Tag Effect Shaders¶

name: allowSpecializedPerTagEffectShaders, type: Enum, default: GVR_AUTO¶: Defines wheter per-tag shading should be used.
