Sample text

Here, we discuss a similar problem: a transformation that allows reshaping a rectangular area directly. Let's assume the coordinate system of the screen is as in Fig. 5. After reshaping, the rectangular area (and all the vertices of the models) go through the following transformations: translate so that the lower-left corner of the area is at the origin, scale to the size of the new area, and then translate to the scaled area location. The corresponding matrix expression is: T(P2)S(sx,sy)T(-P1).

The rotation axis is perpendicular to the 2D plane at the origin: x' = x cos θ – y sin θ , (EQ 16) y' = x sin θ + y cos θ . (EQ 17) In the homogeneous coordinates, rotation can be achieved by matrix multiplication: x' y' = 1 Let's assume R ( θ ) = cos θ – sin θ 0 x sin θ cos θ 0 y . 0 0 1 1 (EQ 18) cos θ – sin θ 0 sin θ cos θ 0 . The simplified rotation matrix equation is: 0 0 1 P' = R ( θ )P . (EQ 19) 2 Transformation and Viewing If a model is a set of vertices, all vertices of the model can be rotated as points by the same angle around the same rotation axis (Fig.

For example, a 2D point (x, y) is (x, y, 0) in 3D, and a 2D rotation around the origin R(θ) is a 3D rotation around the z axis Rz(θ) (Fig. 7). The z axis is perpendicular to the display with the arrow pointing towards the viewer. We can assume the display to be a view of a 3D drawing box, which is projected along the z axis direction onto the 2D drawing area at z=0. θ x z Fig. 1 3D Translation, Rotation, and Scaling In 3D, for translation and scaling, we can translate or scale not only along the x and the y axis, but also along the z axis.
