c++ - CPU Ray Casting - Stack Overflow

WebThis is a work-in-progress project aimed at highly optimized wave simulations in C++ with support for GPU Compute and volume visualization. Currently, there is no support for any form of visualization or a GUI, and everything runs multi-threaded on the CPU. The plan is to integrate Vulkan to hopefully implement volume ray casting, as well as a ... Webxs += dv * 0.1f. At each step, I would floor my xs vector to get a vec2 (int) - which represents the voxel cell I was currently in. This solution works well but fails when casting near the corners of voxels. If your epsilon is too large, you could end up entirely skipping a voxel that your line barely intersects. fishers animal control
