@olonho Basically I'm talking about any way that I can plug into some view (can be canvas) so that custom renderer(opengl/vulkan/directx) can draw into it. Android has such a thing, compose doesn't. In simulations where there are millions of particles, you may need to show them as a whole, because particles can be semi-transparent and pass through each other. No sorting is involved since often it is easier to display millions of objects by instancing than to sort them.
