Abstract
A first set of N samples is located along a ray through a volume in connection with a first frame. The first set of N samples is stored. A second set of N additional samples is located along the ray in connection with a second frame. Then the first and second sets of samples are accumulated.
Claims23
A method comprising:
- locating a first set of N samples along a ray through a volume in connection with a first frame using a hardware processor;
- storing the first set of N samples in a storage;
- locating, using said hardware processor, a second set of N additional samples along the ray in connection with a second frame, the second set being different samples compared to the first set and said second set offset, relative to the first set along the ray through the volume;
- and
- combining said first and second sets of samples, using said hardware processor, so that all samples from the first and second frames are used for the volume.

One or more non-transitory computer readable media storing instructions to perform a sequence comprising:
- locating a first set of N samples along a ray through a volume in connection with a first frame;
- storing the first set of N samples;
- locating a second set of N additional samples along the ray in connection with a second frame, the second set being different samples compared to the first set and said second set offset, relative to the first set along the ray through the volume;
- and
- combining said first and second sets of samples, so that all samples from the first and second frames are used for the volume.

An apparatus comprising:
- a processor to locate a first set of N samples along a ray through a volume in connection with a first frame, store the first set of N samples in a storage, locate a second set of N additional samples along the ray in connection with a second frame, the second set being different samples compared to the first set and said second set offset, relative to the first set, along the ray through the volume, and combine said first and second sets of samples, so that all samples from the first and second frames are used for the volume;
- and
- a memory coupled to said processor.
