Model Dragger

[eryar]

Model Dragger is an efficient way to modify the shape's position and orientation in a 3D scene. Here is a Model Editor in a other software: Figure 1.1 Model Editor on a Equipment Figure 1.2 Locator Handle of Model Editor

Shape Movement

You can move the shape by drag the handler in one constrain axis when mouse move on to it, as the following pictures show: Figure 1.3 Linear Movement in the constrain direction

You can also move the shape constrained in the plane by the Planar Movement Handles: Figure 1.4 Planar Movement

Shape Rotation

You can rotate the shape by the Rotation Handles, Figure 1.5 Rotation Handles

OpenSceneGraph Dragger for Reference

In OpenSceneGraph this are some Draggers to edit the model's position, such as: 1.TabPlaneDragger in OpenSceneGraph

2.TabPlaneTrackballDragger in OpenSceneGraph

3.TrackballDragger in OpenSceneGraph

4.Translate1DDragger in OpenSceneGraph

5.Translate2DDragger in OpenSceneGraph

6.TranslateAxisDragger in OpenSceneGraph

Conclusion

Model Dragger is a tool to modify the shape's position and orientation in 3D software. I will implement such tool in occQt, If you are interested, you can join in!

OpenCASCADE7.1.0 introduce AIS_Mainpulator to do this. I will update occQt by using occt7.1.0 soon.

Hi I have been trying to use your great example with OCCT 7.2.0. I was able to get it to build by adding an extra bool parameters to some of the OCC calls. But although it runs it crashes when I try to create an object like a cone.

@loopless You can send more details of the crashes to me, maybe I can find the problem.

Found the problem... a simple typo mistake on my part when "porting" to 7.2.0.
