keywords	WEM, convert, process

Purpose

The SoView2DWEMEditor provides the possibility of interactively deform a WEM surface in a certain spherical range.

Usage

Connect this module to a View2D inventor input. Connect some WEM to its input.

Make sure you also render the WEM-scene in 2D by using either VoxelizeInventorScene (slow) or SoView2DScene (better). Have a look at the example network.

Details

If clicking onto the View2D in the vicinity of a WEM contour, all nodes in a certain sphere of influence are collected. Those nodes will follow the mouse movement to a certain degree, optionally smoothed by a sigmoid function.

Interaction

Simply click on the 2D viewer into the vicinity of a WEM contour. Hold the according button pressed (whichever you chose on the 'Button' panel) and deform the WEM surface interactively (click & drag).

Visible Fields

Influence Radius

name: influenceRadius, type: Float, default: 10, minimum: 0

The radius of influence around a selected node: all nodes within this radius are deformed.

The radius is measured in world coordinates.

Interpolation Function

name: interpolationFunction, type: Enum, default: WEM_INTERPOLATION_FUNCTION_COSINE

Determines the type of influence interpolation.

Values:

Title	Name	Description
Cosine	WEM_INTERPOLATION_FUNCTION_COSINE	Smooth characteristic.
Linear	WEM_INTERPOLATION_FUNCTION_LINEAR	Triangular characteristic.

Patch Mode

name: patchMode, type: Enum, default: WEM_PATCH_MODE_CLOSEST

Determines which nodes of which WEMPatch are being displaced.

Values:

Title	Name	Description
Closest	WEM_PATCH_MODE_CLOSEST	Only the nodes of the closest WEMPatch are being displaced.
All	WEM_PATCH_MODE_ALL	All nodes of all WEMPatches in the influence radius are being displaced.

Use Angle Damping

name: useAngleDamping, type: Bool, default: TRUE

If checked, only those nodes with a node normal that has an angle less than 90 degree with the node normal of the node closest to the mouse pointer are being displaced.
