This lecture gives an overview of wide-spread direct volume rendering techniques for regular volume data, such as CT and MRI. Raycasting, splatting and texture-based methods are introduced, incl. acceleration techniques, such as early ray termination and empty space skipping. Volume lightning based on approximated gradients is also discussed. Duration: 1 hour, 18 minutes.
Blog on the implementation of a small tool for volumetric rendering, aimed to be minimal and very lightweight, fast, and easy to extend.
