Introduction of Polygon Rendering and Ray Tracing Method
Different type of sources of light and the reflections generated by the object in exposure of these sources. As an object is exposed to light different phenomena arise as reflection, refraction, and so on. Out of them shading is most significant as similar helps in achieving the realism in computer graphics. We have also discussed the idea of polygon rendering, and ray tracing that are helpful in achieving photo realism of a 3-D scene.
Scan Line Algorithm A scan line algorithm determines the overlap intervals of the polygon with each scan line to obtain interior points of the polygon for assigning those point
Translate a triangle and scale it in each coordinate direction Consider a triangle with vertices in 2D plane given by (0, 0), (1, 0) and (0,1) (called unit triangle). Translat
What is persistence and resolution? The time it takes the emitted light from the screen to decay one tenth of its original intensity is known as a persistence. The maximum
Achieve a perspective projection on the z = 0 plane of the unit cube, demonstrated in Figure (l) from the cop at E (0, 0, 10) upon the z-axis. Figure: I 01: currently c
Variation of Intensity - Modeling and Rendering According to the phong model the variation of Intensity (I) along with α (since I α cos n α) is: i) for shiny surface (

Perspective Projection 1. Perspective projection gives more realistic appearance and uses the same principle as used in camera. 2. Perspective projection is not an affine tr
Example: Exemplify the Bresenham line generation algorithm through digitizing the line along with end points (20, 10) and (30, 18) Solution: m = (y2 - y1)/( x2 - x1) =
