A transformation in 3d graphics means “doing something to every part of an object”. Their development is motivated by the process of converting coordinates between frames, which results in the generation of a matrix. Explain scaling in 2D Transformations 2011 3 3. In computer graphics systems there can be many transformations combined, and this is done by multiplying them all together (two at a time) to produce one matrix that does all the transforms in one go. This can be done by applying a geometric transformation to the coordinate points defining the picture. A matrix with n x m dimensions is multiplied with the coordinate of objects. 2D-Transformations Contents Why transformations Transformations • Translation • Scaling • Rotation Homogeneous coordinates Matrix multiplications Combining transformations Transformation • What is transformations? • The geometrical changes of an object from a current state to modified state.
