2-Dimensional Modeling Transformations

Introduction

Modeling transformations are the mechanism used to compose an image from modeling primitives. The modeling proimitives are defined in their own modeling coordinate system and then placed in the final scene by using modeling transformations. We can change the Camera position or World Coordinate Window to scale or move an entire image, but we may want to only change a particular part of the image.

Example: We might want to translate and scale the tall house but not change the short house. We can't do this by modifying the window, so we want to apply transformations to the individual objects in the scene.

Possible modeling transformations include the following:
