3D Primitive and Composite Transformations
Previously you have studied and implemented 2D geometric transformations for object definitions in two dimensions. These transformations can be extended to 3D objects by including considerations for the z coordinate. In this unit, you will study certain methods to implement such transformations.
You must have noticed here that the translation is as simple as in 2D. Rotation however requires a little more effort in 3D. Standard rotations about three coordinate axes are simpler to perform. In order to apply rotation about an arbitrary axis, you need to have a composite transformation while scaling, shear and reflections are generalized to 3D in a natural way.
scan conversion of circle
Main Objectives of this connector is to allow full duplex communication between peripherals that uses such connector such PIC Demo board, ICD2 Debugger etc. The RS32 connector pin
Algorithm (scan-line): For each scan line perform from step (1) to (3). 1) For all pixels on a scan-line, arrange depth [x]=1.0 i.e. max value and Intensity [x] = background
Need for Video Compression: T he high bit rates that result from the various types of digital video make their transmission through their intended channels very difficult. Eve
Characteristics of vector drawings: Vector drawings are generally pretty small files as they include only data about the Bezier curves which form the drawing. The EPS-file format
Bezier curves: Theses are special polynomial curves expressed using Bernstein polynomials. Spline curves are simple extensions of Bézier curves composed of two or more polynom
Beam Penetration Method and Shadow Mask Method Two methods exist for displaying colors in a CRT monitor - beam penetration method and shadow mask method. Beam penetration metho

Transformation for parallel projection Parallel projections is also termed as Orthographic projection, are projections into one of the coordinate planes as x = 0, y = 0 or z
Question: Is CAD only helpful for design drawings? No. When true-scale, structurally valid drawings are the purpose for CAD's existence; it utilizes is as diverse as imagination
