I jumped on the new orthographic projection feature as I needed it, and saw a several problem rigth away : one cannot zoom anymore, instead the plot is hidden partly when one scrolls, for example. This is actually already visible on the demo shown in the original pull request. I thought the bug would go away in the final release but it is still there. When one goes back to standard projection, zoom works.
Could you help fixing this?
Thanks.

Hello @emimoun,
Thanks for testing the orthographic feature.
The zoom on this projection is working similar to perspective projection i.e. panning in z direction (webgl Y axis). So if you continue zooming you may notice that the near clip could slice the data cube which is in fact very useful for exploring the 3-D data.
Here is an example you could quickly test this behaviour: https://rreusser.github.io/plotly-mock-viewer/#gl3d_isosurface_9more-surfaces_between-ranges_orthographic.
And here is another codepen that may be of interest.
As another note if you would like to scale the graph in the viewport, it is possible to simply use the aspectratio attribute on the layout.scene.
Hope this info may be helpful.
As useful as slicing may be, I think I'm with @emimoun on this one - the zoom interaction should make the scene bigger or smaller, whether we're using perspective or orthographic projection. If we were to design a slicing feature, we would want it to work differently: somehow tied to visual indicators of where you're slicing - at an axis value, for example - and keeping that slice as you rotate. Using zoom to create a slice is unintuitive and limited to slicing orthogonal to the depth direction.
