Ngl: wishlist: camera: orthographic or perspective

[hainm]

option to change the camera type (and can be changed in notebook)

[arose]

started working on this in the orthographic branch

• [x] integrate CombinedCamera (perspective & orthographic) including methods to switch
• [ ] fix hyperball impostor (just noise)
• [ ] fix sphere impostor (bounding box too small)
• [x] integrate OrthographicTrackballControls (also, make feel more similar to TrackballControls)
• [x] fix multi-sample antialiasing (needs offset for OrthographicCamera)
• [x] add camera switch to preferences

ongoing work in PR https://github.com/arose/ngl/pull/115

[arose]

merged the PR, testing appreciated

[hainm]

can you create a branch in NGLView with updated NGL code for camera? And how to change camera type? I can test it but prefer to use notebook. :D

[arose]

stage.setParameters({cameraType: "orthographic"})

[hainm]

so I did

cd ngl/build
`sh make.sh

then copy js/build/{ngl.js, three.custom.min.js} to NGLView. Nothing shows up. Open JS console and saw

[.CommandBufferContext]GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : glClear: framebuffer incomplete

[hainm]

done. work nicely.
