We should be able to implement visualization of symmetric and non-symmetric matrix fields via superquadrics (e.g. [1,2]) with moderate effort. For this we might need some changes to Makie.jl, where we start from meshscatter and implement a new shader to render out the superquadrics. The matrix field should be evaluated either at quadrature points or nodes.

It might make sense to explore the possibility to put everything into a single mesh and push it into the renderer, eliminating at least the draw call overhead.
