Computer Graphics Transformations An Introduction To 2d The fundamental 2d transformations in computer graphics are translation (moving objects in a specific direction), rotation (changing orientation around a point or axis), and scaling (resizing objects by applying scaling factors to coordinates). So if graphics images are coded as numbers, the numbers can be stored in memory. these numbers are modified by mathematical operations called as transformation.
Transformations Pdf 2 D Computer Graphics Shape There are several transformations that are used in computer graphics, but the most common ones are translation (moving the object), rotation (spinning it) and scaling (changing its size). Computer graphics requires that shapes are manipulated in space by moving the shapes, shrinking or stretching, rotating and reflection to name a few. we call these manipulations transformations. Transformations to change coordinate systems issue: the world has many different relative frames of reference how do we transform among them? example: cad assemblies & animation models. Graphics systems maintain a current transformation matrix (ctm). all geometry is transformed by the. ctm. the ctm defines the current or object or local coordinate system. all geometry is defined in the current coordinate system. transformation commands are concatenated onto the ctm.

Transformations transforming an object = transforming all its points for a polygon = transforming its vertices. 3 d transformation: in very general terms a 3d model is a mathematical representation of a physical entity that occupies space. You will think of some of those transformations as modeling transforms and some as coordinate transforms, but to the computer, it's all the same. here is a live demo that can help you to understand the equivalence between modeling transformations and viewport transformations.
