Abstract: A method may include providing geometry data and attribute information of the model in one or more data structures on a data storage device and performing a rendering process for providing a visualization of the model on the display for each of the multitude of viewpoints. The rendering process may include rendering a multitude of like 3D arrays in a single draw call, each array comprising at least eight voxels, removing voxels that are not to be visualized by folding vertices to a centre of the array, computing a distortion on a mapping from voxel space to attribute volume space in dependence on the removed voxels, assigning attributes to the voxels of the multitude of arrays using distorted values for retrieving attribute values from attribute volume space, the attributes being assigned to the remaining voxels according to the computed distortion, and visualizing the voxels of the multitude of arrays.
