SliceDensityPlot3D
SliceDensityPlot3D[f,surf,{x,xmin,xmax},{y,ymin,ymax},{z,zmin,zmax}] generates a density plot of f over the slice surface surf as a function of x, y, and z.
SliceDensityPlot3D[f,surf,{x,y,z}∈reg] restricts the surface to be within region reg.
SliceDensityPlot3D[f,{surf1,surf2,…},…] generates density plots over several slices.
