WebRay Tracing Fundamentals. Ray casting is 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 the 3D scene hits a primitive, then the distance along the ray … WebRay tracing at interactive frame rates has been first presented by [Muu95a]. Later, [Par99a] described a full-featured interactive ray tracing system running on a shared-memory supercomputer that is able to handle arbitrary geometry, including parametric surfaces (e.g. NURBS). However, they had to use expensive high-end hardware to achieve this ... lithia college station
