To transform from the world coordinate system to viewing coordinate system you need to perform the following operations.
a) Translate the viewing coordinate origin to the world coordinate origin (and hence the scene).
b) Rotate the axes so that your viewing coordinate system has the same orientation as the world coordinate system.
While performing such an operation, you are actually performing a change of basis transformation. This again results in another orientation of three mutually perpendicular (linearly independent) unit vectors.
Card or Page Based Tools : In these authoring systems, components are organized as pages of a book or a stack of cards. Thousands of pages or cards may be obtainable in the stack

What is fixed point scaling? The location of a scaled object can be controlled by a position known as the fixed point that is to remain unchanged after the scaling transformat
Rotation - 2-D and 3-D transformations Within 2-D rotation, an object is rotated via an angle θ along w.r.t. the origin. This angle is assumed to be +ive for anticlockwise rot
