ABSTRACT:
A method of volume rendering two digital images includes providing a volume-rendering computing sub-system, loading a first image volume into a memory of the volume-rendering sub-system, rendering the first image volume, wherein a 2-dimensional image is output into an image buffer and a set of depth values are output into a depth buffer, loading a second image volume into a memory of the volume-rendering sub-system, rendering the second image volume up to the depth values output from the first image volume, wherein values from the rendering of the second image volume are merged with non-zero values of the image buffer, and rendering the remainder of the second image volume to include second image volume points beyond the depth values output from the rendering of the first image volume, wherein values from the rendering of the remainder of the second image volume are merged with non-zero values of the image buffer.
