I am using nvindex plugin for paraview 5.9.0. It is working really well. I have successfully run the custom kernel examples that ship with paraview 5.9.0 under kernels_nvidia_index folder to check the custom kernels and they all are good basic usage examples. I want to know a bit more about the capabilities of XAC programming to control the volumetric shading looks and here are some questions in this regard.
- Does XAC allow spawning of more rays? Lets say I want to cast a new ray in some direction towards a parametric light source. Is it possible ? if so how?
- I notice that XAC volume program automatically samples the volume using a raycasting/raymarching process for each pixel and calls the execute function at an intersection. Can I change the step size of this raymarching? Can I change the volume sampling process altogether to make my own free path sampling routine?
Sorry if these questions are a bit off for paraview community but I am unable to find any forum on nvidia developer site to post these questions on. If you know any forum where i may post these questions then please do let me know.
