Introduction
SIMDVoxelizer is a CPU-based voxalizer taking advantage of vectorization units to speed up creation of 8bit raw volumes.
usage: SIMDVoxelizer <voxel_size> <cutoff_distance> <input_file> <output_file>
Input file is a binary array of floats: x, y, z, radius and value of elements. Each voxel of the final volume contains the sum of all elements with a weight that correspond to the value of the element divided by its squared distance to the voxel. Note that in the final volume, values are normalized.
This is currently a brute force implementation that produces accurate 8bit volumes.
The <output_file> is suffixed by the size of the volume.
SIMDVoxelizer makes use of the Intel ISPC compiler.
