Ray casting computer graphics
WebIn this study, we developed a 3D-model-based technology that can evaluate solar access by analyzing solar radiation and shade to find the optimal location for a solar system. We developed an algorithm that can quickly calculate viewshed by applying ray-casting technology, which is useful in the field of computer graphics. To apply the developed … WebMar 23, 2024 · Now imagine tracing those rays of light backward from the eye with a piece of string like the one Dürer used, to the objects that light interacts with. That’s ray tracing. Ray Tracing for Computer Graphics Turner Whitted’s 1979 paper, “An improved illumination model for shaded display,” jump-started a ray-tracing renaissance.

WebAug 2, 2013 · These strategies are called ray casting and rasterization. We’ll build software renderers using each of them. We’ll also build a third renderer using a hardware rasterization API. All three renderers can be used to sample the light transported to a point from a specific direction. A point and direction define a ray, so in graphics jargon ...

Instead of rendering pixels on a row-by-row basis down the entire image, you render them in 2D groups (say, 32x32 tiles). Since adjacent rays tend to intersect the same objects, this improves the cache hit rate at the CPU level.
