I don't think Flex can easily answer a query like "how deep is a point inside the fluid". To get an accurate answer I think you would need to build an SDF from the particles, e.g.: splat them to a grid and then run a general SDF algorithm.
Alternatively, you could try putting a layer of particles around the mesh and then use NvFlexGetDensities() to read the density for those particles. It's not exactly "depth", but might be enough depending on your needs.
Hi,
We are using FleX for fluid simulation in our Temporal Bone simulator for suction/irrigation. We have two collision meshes for the drill and irrigation device, and a SDF for the volumetric dataset. I'm interested in getting a numerical value based on a mesh location to determine how deep the fluid is at that location, basically how much fluid is covering the drill, and how far into the fluid is the suction/irrigation device.
I can determine if the drill is completely submerged using glBeginQuery/glEndQuery, but this will only tell me what percentage of the drill bit is occluded by fluid, and I would like to know how deep is the fluid.
Thanks!
