Rearrange steps involved in two dimensional viewing transformations.
Rearrange steps involved in two dimensional viewing transformations.
I. Map normalized viewport to device co-ordinates
II. Convert world co-ordinate to viewing co-ordinates
III. Construct world co-ordinate scene using modeling coordinate transformation
IV. Map viewing co-ordinates to normalized viewing co-ordinates using window-viewport specification
Show answerHide answer
Correct answer: (A) III → II → IV → I
Explanation
2D viewing: build the world-coordinate scene from modeling coordinates (III), convert to viewing coordinates (II), map to normalized coordinates using the window-viewport mapping (IV), then map to device coordinates (I).
