Raycasting is the rst step in raytracing, which allows us to calculate a correct shade for each pixel. For now, let us look just at the raycasting problem. The diagram to the right will help us to …

Raycasting is historically the first volume rendering technique. For each pixel ... Images generated using a ray casting method with three different step sizes (or sample rate). Vase data courtesy …

Computation of the light that is transported along primary rays. Which color does it have? Secondary rays are used. Outgoing light into direction (primary ray) is a sum of incident light …

For each sample ... Check if point inside triangle. BSP trees Next Time!

Efficient ray tracing of volume data. ACM Transactions on Graphics, 9(3):245-261, 1990. S. Parker et al., Interactive ray tracing for volume visualization. IEEE Transactions on …

Raycasting is historically the first volume rendering technique. It has common with raytracing: A ray template (Yagel 1991) is a voxelized ray which by translating generates all view rays. Ray …

In the next section, we will first introduce the basic idea of hardware raycasting and how the algorithm works. In section 3 we will extend this technique by adding a more sophisticated …
