DEFINITION It is a technique for generating an image by tracing the path of the light in an image plane and simulating the effects of the encounters. 5. DIAGRAM OF RAY TRACING 6. EXPLANATION Firstly The objects are stored in the sorted order. For each pixel construct a ray that starts from the eye through lower left corner and upper right ...

What is ray tracing • Ray tracing is a technique for rendering three- dimensional graphics with very complex light interactions. This means you can create pictures full of mirrors, transparent surfaces, and shadows, with stunning results. • A very simple method to both understand and implement.

What is Ray Tracing ?The alternative to rasterization-based methods (like OpenGL or DirectX).Image-Order algorithm. Every pixel is processed separately.Slower than rasterization methods in the case of few primitives to render. Rarely used in games, widely used for realistic computer graphics.www.povray.org. *Benjamin MoraUniversity of Wales Swansea
