Ray-casting algorithm is an important volume rendering algorithm, which is widely used in medical image processing. Aiming to address the shortcomings of the current ray-casting algorithms in 3D reco...
Ray castingis the process in a ray tracing algorithm that shoots one or more rays from the camera (eye position) through each pixel in an image plane, and then tests to see if the rays intersect any primitives (triangles) in the scene. If a ray passing through a pixel and out into th...
namely theboundedness, theexclusion of the originand thegap-free ray intersection, see Section 3. The ray casting algorithm works with equiangular rays (e.g. in polar coordinates) which start at the origin. The origin is never a feasible point. If a certain pointxis feasible, then the comp...
The Boeing 777 model (almost 400 million polygons) ray traced at interactive rates on a consumer-level PC, using CUDA. CentiLeo is an out-of-core GPU ray tracer, see this page for some of the slides from the (rather long) video. That said, don’t be fooled by the start of the vi...
We have developed a new algorithm for the randomized incremental construction of the visibility complex. The advantage of using an incremental algorithm is that the history of the incremental construction yields an efficient ray-query data structure, which is required for casting secondary rays. The ...
In this shader I'm using a box. Besides rays, you can also cast cones or spheres. Raytracing is a light transport algorithm, like pathtracing, radiosity or photon mapping. Raytracing uses raycasting, which in turn can be analytical or raymarched or both. Wikipedia or other sources might ...
point in a set of data points, the system identifies a relevant interval on the reference line that the data point projects onto, and performs a crossing number operation to identify polygons that the data point falls into, and the system increments a count for each polygon that the data ...
Ray tracing is a primitive used in a variety of rendering algorithms including for example path tracing and Metropolis light transport. In an example algorithm, ray tracing simulates the physics of light by modeling light transport through the scene to compute all global effects (including for exam...
