MeshCat.jl

Breaking Changes

• Fixes our usage of GeometryTypes.Cylinder: #81

New Features

• More options for open(): #89 #84
• Compatibility with WebIO 0.7 (which is actually the same as WebIO 0.4.2): #88

Thanks to @tkoolen for the updates!

• Fix open_url on Windows (@traversaro): #73
• Update MeshCat javascript for better lighting: #70
• Require Julia 0.7 or higher: #69

Workaround for https://github.com/JuliaLang/julia/issues/21653

• Added animation support with setanimation!(). See animation-demo.ipynb for details
• Added support for setting object properties with setprop!. See animation-demo.ipynb for examples
• Removed git submodule for future Pkg3 compatibility
• Upgraded meshcat javascript library:
  • Support moving and modifying the camera (see animation-demo.ipynb)
  • Better default lighting conditions (thanks @gizatt)
  • Support recording animations to video

This should fix build issues on systems without git installed (as is common on Windows)

This release updates all of MeshCat's internal communication to use WebIO.jl. That means that, in addition to working in Jupyter and in a standalone browser tab, MeshCat will also work inside Juno and in a standalone Blink.jl window. Jupyter integration is now better, and it should be possible to use MeshCat even on a remote Jupyter server like JuliaBox.

This change does, however, break compatibility with the old ZMQ interface. That means that communication between Julia and Python MeshCat sessions is not currently possible.

Note: this release breaks compatibility with the meshcat-python implementation, due to https://github.com/JuliaInterop/ZMQ.jl/issues/167 . I'm planning to bring back compatibility after the big WebIO.jl rewrite.

• Fix zero-width boxes
• Switch from our own HyperCylinder to GeometryTypes.Cylinder
• Support arbitrary GeometryPrimitive subtypes (like Polyhedra.jl) using the decompose interface
