TAILIEUCHUNG - Lecture Computer graphics - Chapter 4: Transformations

Transformations are used both by the applications programmer to move and orient objects (either statically or dynamically) and by OpenGL to implement the viewing pipeline. Three transformations (model-view, perspective, texture) are part of the state. Their matrices can be set by application programs but the operations are carried out within the viewing pipeline. | Transformations An Interactive Introduction to OpenGL Programming 1 Transformations in OpenGL Modeling Viewing orient camera projection Animation Map to screen 2 An Interactive Introduction to OpenGL Programming 2 Transformations are used both by the applications programmer to move and orient objects (either statically or dynamically) and by OpenGL to implement the viewing pipeline.

Camera Analogy 3D is just like taking a photograph (lots of photographs!) 3 camera tripod model viewing volume An Interactive Introduction to OpenGL Programming 3 This model has become know as the synthetic camera model. Note that both the objects to be viewed and the camera are three-dimensional while the resulting image is two dimensional. Camera Analogy and Transformations Viewing transformations tripod–define .
