Translate the object so that the pivot point is returned to its original position. The composite transformation matrix for this process is 3. Digital painting techniques vol 1 pdf. Scaling A scaling transformation alters the size of an object. This operation can be carried out for polygons by multiplying the coordinate values (x, y) of each vertex by scaling factors sx and sy to produce the transformed coordinates (x’, y’).

To perform 2D transformations such as shearing and reflection on 2D object. C / C++ Program,learning.

In General Fixed – Point Scaling, there are 3 steps to scale an object about the fixed point, • Translate object so that the fixed point coincides with the coordinate origin. • Scale the object with respect to the coordinate origin. • Use the inverse translation of step 1 to return object to its original position. The composite transformation matrix for this process is Source code.
