Abstract
A method for sampling volume data of an object in an imaging device is disclosed. The method includes creating a voxel dataset of a first volume associated with the object using a scanning device and saving the voxel dataset; defining a grid of sampling positions by casting rays through the first volume and choosing a number of points along a respective ray; choosing a sampling access pattern that defines a sequence of the sampling positions; selecting an interpolation scheme mapping the sampling access pattern to a voxel access pattern defining a sequence of the voxels of the voxel dataset; successively loading memory lines of a main memory comprising the data associated with the respective voxel into a cache memory if the memory line is not already present in the cache memory; and processing the data associated with the respective voxel, the cache memory access being optimized for rendering time performance.
