WebAug 9, 2024 · Consider an image with N pixels. We shoot a ray through each pixel and sample some points on the ray. A ray is commonly parameterized by the equation r (t) = o + td where t is the parameter, o is the origin and d is the unit directional vector as shown in Figure 6. Figure 6: r (t) = o + td where t is 3. WebOct 25, 2015 · I'm well aware of the marching / DDA algorithms, but instead I would like to be able to do a per voxel-ray pair check, in constant time, without having to "march" through …
