Volume raycasting and particle advection
There are two things I'm trying to achieve that VTK-m is supposed to have algorithms for: raycasting a volume and particle advection. After some days of learning and playing with VTK-m I start realizing that those algorithms that are discussed in papers by the VTK-m team are actually not incorporated in the publicly available code.
The furthest I got with ray casting is the vtkm::rendering::MapperVolume
class which I don't even know what it really suppose to do, and anyway my attempt to use it only got me an opaque object. Issue #303 (closed) here @kmorel says "Since we already have an internal raycasting rendering system [...]", so I'm wondering whether he refers to this mapper or something completely different that I miss. Is the beautiful supernova rendering in the 2016 IEEE paper something I can reproduce using VTK-m without implementing my own ray casting renderer? Otherwise, is that code available somewhere?
