Clipping mode and initial zoom level

[Kevin-Mattheus-Moerman]

I have a shape with units in mm (and it is a residual limb segment for a below knee amputee so about the side of a foot/leg). From this animation you can see that the initial zoom state is not great and also view clipping prevents me from viewing the geometry when I attempt to zoom out.

1. Could the initial zoom level (and horizontal grid field size) be based on the visualized entities in an automated way? Alternatively how can I set the axis limits/units/or initial zoom state?

2. Can clipping be turned off? Or can one change the zoom mode such that we do not "fly through" but "zoom at" (ever closer without cutting)?

Thanks.

Code I used:

using MeshCat
using MeshIO, FileIO
using Colors
using GeometryTypes: vertices

vis = Visualizer()
open(vis)
cube = load("/home/kevin/Desktop/temp/ampscan/tests/stl_file.stl")
setobject!(vis[:mesh], cube)

Hm, that's a good point. I think you'll have a better experience all around if you rescale your objects to be ~unit scale. In your case, you can probably do:

setobject!(vis[:mesh], 
    HomogenousMesh(0.001 .* vertices(cube), faces(cube))

But if that's not an option, then at least some of this can be fixed programmatically. You can change the clipping behavior by changing the "far" property of the default camera. You would do that by running:

julia> setprop!(vis["/Cameras/default/rotated/<object>"], "far", 10000)

Likewise you can control the initial position of the camera (without affecting its field of view) by changing its "position" attribute (see https://github.com/rdeits/meshcat#camera-control ):

julia> setprop!(vis["/Cameras/default/rotated/<object>"], "position", [1000, 0, 0])

The grid is slightly trickier: it doesn't seem to handle property updates correctly, so I'm not sure how to scale it programmatically. You can just hide it if it's annoying:

julia> setvisible!(vis["/Grid"], false)
