I'm asking because AFAIK unlike Windows with Direct2D, Linux doesn't have GPU-targeted vector graphics libraries. I have once made my own one when I needed something similar: https://github.com/Const-me/Vrmac#vector-graphics-engine
I'm using 3D graphics APIs, OpenGL on Linux currently, but Vulkan will be an option later. I'm converting everything to triangles on the CPU and send to OpenGL.
Note that the animation app actually needs to show 3D graphics for a 2D+time visualization which is part of the innovation in my research.
