Tree components

[AlbertoCasasOrtiz]

Implemented:

• Allow selecting elements in the tree #201
• Previsualization of selected camera #197
• Fix issue with tree update when it changes #194
• Buttons to switch between translate and rotate methods in transformcontrols #193
• Adjust new stree style when switched to dark mode #205
• Allow both orthographic and perspective cameras #206

Note: I had to remove the "Bounds" Component around OpenSimScene as it was causing problems. This makes the viewer start too far away from the scene, so we have to zoom in. We need a solution for this.

Thanks @AlbertoCasasOrtiz The tree looks good. I'm trying to figure out how to avoid the view totally zoomed out on loading a model from the gallery, is there a specific hook or function that you call to adjust the default camera on loading?

@AlbertoCasasOrtiz I started a document describing the layout of the scene. Basically when using the GUI (using my own component that pulls from the viewer and communicates with the GUI) I create groups as shown here

opensim-viewer/src/components/Components/OpenSimGUIScene.tsx

Line 373 in 155ac6f

<group name='OpenSimEnvironment' ref={envRef}>

At the end of loading I adjust the camera to fit to the models group. I started a google doc to discuss/refine this design so we're on the same page and shared it with you
