Visible Fields

Enable Rendering

name: enableRendering, type: Bool, default: TRUE

If checked, the module renders normals.

Enable Picking

name: enablePicking, type: Bool, default: TRUE

If checked, the primitives rendered by this extensions are pickable.

Color Mode

name: colorMode, type: Enum, default: WEM_COLOR_GENERAL

Defines the color mode.

Values:

Title	Name
​General	​WEM_COLOR_GENERAL
​Node Colors	​WEM_COLOR_NODE_COLORS
​Lut Values	​WEM_COLOR_LUT_VALUES
​Lut Values Integer	​WEM_COLOR_LUT_VALUES_INTEGER

Global Alpha

name: globalAlpha, type: Float, default: 1, minimum: 0, maximum: 1

Sets a global alpha value that is multiplied with all existing alpha values.

General Color

name: generalColor, type: Color, default: 1 1 1

Sets a general color for the general color mode.

General Alpha

name: generalAlpha, type: Float, default: 1, minimum: 0, maximum: 1

Sets a general alpha value for the general color mode.

Use Lighting Mode

name: useLightingMode, type: Bool, default: FALSE

If checked, the Lighting Mode is applied.

Lighting Mode

name: lightingMode, type: Enum, default: SoShaderPipelineDefinition::LIGHTING_PER_VERTEX

Defines which lighting mode is applied. See SoShaderPipeline for more information.

Values:

Title	Name
​OFF	​SoShaderPipelineDefinition::LIGHTING_OFF
​PER FRAGMENT	​SoShaderPipelineDefinition::LIGHTING_PER_FRAGMENT
​PER VERTEX	​SoShaderPipelineDefinition::LIGHTING_PER_VERTEX

Override Selected PVL

name: overrideSelectedPVL, type: String

Sets the used PVL. The module supports per-node PVLs.

Normal Scale

name: normalScale, type: Float, default: 1

Sets a scale value for the length of all normals.

Line Width

name: lineWidth, type: Float, default: 1, minimum: 1

Sets the line width in pixels.

Normal Mode

name: normalMode, type: Enum, default: NODE_NORMALS

Defines the rendering mode for normals.

Values:

Title	Name	Description
​Face Normals	​FACE_NORMALS	​Renders the face normals. If the color is not ‘General’ the color of the face normal is the average color of the adjacent nodes. Same is true for the alpha value.
​Node Normals	​NODE_NORMALS	​Renders the node normals.
