I have to render a real cloud of double[500][500][100], likehttps://wci.llnl.gov/simulation/computer-codes/visit/gallery/gallery-34
Dose UE have volume rendering (not surface rendering) algorithm?
In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.
A typical 3D data set is a group of 2D slice images acquired by a CT, MRI, or MicroCT scanner.
Usually these are acquired in a regular pattern (e.g., one slice for each millimeter of depth) and usually have a regular number of image pixels in a regular pattern.
This is an example of a regular volumetric grid,...
splatting or Volume ray casting or Shear warp

Volume rendering is fully covered in this forum thread , including code samples.
For long answer, you should check the thread.
