1. A computer-implemented volume rendering method comprising:
receiving a first data set comprising time-varying 4D volume data comprising volumetric scene views;
partitioning the first data set into a plurality of layers each representing a portion of the scene;
encoding multiple layers to generate a second data set comprising a layered scene decomposition of volume data comprising a plurality of pixels;
selecting a fixed transfer function, wherein the transfer function maps density of materials represented by the volumetric scene views to color and a transparency value associated with each pixel in the second data set;
decoding the second data set using a Computational Neural Network trained for the selected transfer function.
