Purpose

The SoWEMInteract module allows for drawing a contour onto the screen. The portion of the input WEM that falls into this contour is tagged. The input WEM is then split into two halves.

Usage

Add the Open Inventor output to a SoExaminerViewer and draw a contour.

Details

The contour is drawn in screen coordinates. The input WEM is projected onto the screen. All nodes that fall inside the contour are tagged. Afterwards the WEM is divided in two halves based on this tagging.

Interaction

Use a SoExaminerViewer to draw a contour. Every new interaction creates a new contour and adjusts the tagging of the input WEM.

Tips

Connect a toggle button from SoKeyGrabber to the Tag Nodes field to interactively allow for tag/untagging of the input WEM as can be seen in the example network.

The projection works incorrectly with a perspective camera, you should use an orthographic camera instead.

Visible Fields

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, the module computes on changing any parameter value.

Auto Update

name: autoUpdate, type: Bool, default: TRUE

If checked, the module computes anew on each input change.

Apply

name: apply, type: Trigger

When pressed, the module computes its output anew.

Hit Points

name: hitPoints, type: Vector2List, default: 0 0

Sets a number of x y pairs in screen coordinates can be given for the splitting contour.

Tag Nodes

name: tagNodes, type: Bool, default: TRUE

Sets whether the nodes of the WEM that lie inside the drawn contour are being tagged or not.

Generate Edges

name: generateEdges, type: Bool, default: TRUE

If checked, the output WEMs will have edges even though no edge information existed in the input WEM.
