Purpose

The SoWEMRenderer renders a WEM as an OpenInventor scene.

Usage

Just plug in a WEM into the input, and the module's output into an Inventor viewer.

Interaction

A rendered WEM can be selected in the viewer. On the module?s GUI, some information on the clicked position, the id of the hit WEMPatch, as well as some additional information on the local configuration of the hit position is displayed.

Windows

Default Panel

Input Fields

The input is the WEM to be rendered and an option LUT for coloring the WEM (only meaningful if the WEM has values stored in at least one PVL).

inWEM

name: inWEM, type: MLBase

inLUT

name: inLUT, type: MLBase

Output Fields

The WEM as an Inventor scene.

Visible Fields

Allow Hits

name: allowHits, type: Bool, default: TRUE

If checked, the module evaluates picking information.

Apply

name: apply, type: Trigger

if pressed, the module generates a new Inventor scene.

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, all parameter changes lead to a new generation of the output scene.

Auto Update

name: autoUpdate, type: Bool, default: TRUE

If checked, all input changes lead to a new generation of the output scene.

Color Mode

name: colorMode, type: Enum, default: WEM_COLOR_GENERAL

Determines how the WEM (faces) should be colored.

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
Textured	WEM_COLOR_TEXTURED

Hit Face

name: hitFaceIndex, type: Integer, persistent: no

The index of the hit (picked) face.

Hit Patch

name: hitPatchIndex, type: Integer, persistent: no

The index of the hit (picked) WEMPatch.

Hit Pos.

name: hitPosition, type: Vector3, persistent: no

The position where the picking ray first hit the surface.

Hit information valid

name: isHitInformationValid, type: Bool, persistent: no

This field is true if the hit information on the GUI is valid.

Mode

name: parameterOverwriteMode, type: Enum, default: OVERWRITE_MODE_ALL

Determines which visualization parameters should be overwritten by the renderer and which parameters should be taken from the input WEM.

Values:

Title	Name
None	OVERWRITE_MODE_NONE
All	OVERWRITE_MODE_ALL
Specific	OVERWRITE_MODE_SPECIFIC

Nearest Node

name: hitNearestNodeIndex, type: Integer, persistent: no

The index of the nearest node to the hit position.

Nearest Value

name: hitNearestNodeValue, type: Float, persistent: no

The value of the node nearest to the hit position.

Use automatic polygon offset

name: usePolygonOffset, type: Bool, default: TRUE

If checked, the module used internal polygon offsets to enhance the visual result if edges and faces are rendered at the same time.

Use internal shape hints

name: useShapeHints, type: Bool, default: TRUE

Determines if the module uses internal shape hints. If so, all external shape hint setting will be overwritten.
