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 ...

Ray tracing 1. Ray Tracing 1 2. 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

16 Ray-Polygon Intersection Find the plane in which the polygon sits A plane can be defined by: A normal vector and a point And has the equation where P n = (A, B, C) gives the normal and if normalized (A 22+ B + C = 1), F will give the shortest distance to the plane from the origin of the world.

Ray tracing is probably the best known technique for higher quality graphics. The idea behind it is not complicated: To find out what you see when you look in a given direction, consider a ray of light that arrives at your location from that direction, and follow that light ray backwards to see where it came from.

Whitted introduced ray tracing to the graphics community in 1980: • recursive ray casting • first global illumination model: • slow, batch rendering an object’s color is influenced by lights and other objects in the scene shadows • simulates specular reflection and refractive transmission image plane Merrell08 Whitted80 Ray Tracing ...
