Feature Discussion: more 3d visualisation options

[activityworkshop]

For the 3d visualisation of tracks and terrain, GpsPrune currently has two options:

• Interactive view using Java3D (if installed), lets you rotate / zoom / pan the model and look from different angles
• Export to .pov format for separate rendering of the model by povray, with a fixed orientation

I'm thinking perhaps there are other options to be explored, maybe there are better ways to view the model? Preferably without adding huge dependencies. So I'm looking for suggestions on what could be done here, for example:

• Rendering in Blender? Except I don't know Blender and don't know how to get the data in there
• Using "Processing" from GpsPrune's java code? Except the install for Processing is over 400 MB
• Writing a webpage which uses p5.js and viewing that locally-written file in a browser?

If anyone has any clarifications on these, or could offer some help / links, or has any alternative suggestions then please feel free to comment!
