Output Primitives and Geometric Transformations
You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting on a display unit. In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
3D Primitive and Composite Transformations Previously you have studied and implemented 2D geometric transformations for object definitions in two dimensions. These transformati
Rotation about the origin - 2-d and 3-d transformations Specified a 2-D point P(x,y), which we need to rotate, along with respect to the origin O. The vector OP has a length '
2D Clipping Algorithms Clipping is an operation that eliminates invisible objects from the view window. To understand clipping, recall that when we take a snapshot of a scene,
What is the advantages and disadvantages of reflection ?
Application of animation: There are a variety of utilizations for computer animation. They can vary from fun to practical and educational ones. Medicine, military, entertainment,
Viewing Transformation In previous section, we have discussed about the geometric transformations as Translation, Shearing, Reflection, Scaling and Rotation. Rotation, Reflect
What happens while two polygons have similar z value and the z-buffer algorithm is utilized? Solution : z-buffer algorithms, varies colors at a pixel if z(x,y)
