X, −y . −x, −y . 1 Verify that the preceding five transformations are linear. 2. We defined transformations as acting on a single point at a time, but of course, a transformation also acts on arbitrary geometric objects since the geometric object can be viewed as a collection of points and, when the transformation is used to map all the points to new locations, this changes the form and position of the geometric object. 1 asked you to calculate how transformations acted on the F shape. 1 2 Points and vectors in 2-space both consist of a pair of real numbers.

Conclude that M represents an orientation-preserving transformation if and only if det(M) > 0. Also, prove that if u and v are unit vectors that are orthogonal to each other, then setting w = u × v makes M = (u, v, w) a rigid, orientation-preserving transformation. Any affine transformation is the composition of a linear transformation and a translation. Since a linear transformation can be represented by a 3 × 3 matrix, any affine transformation can be represented by a 3 × 3 matrix and a vector in R3 representing a translation amount.

The typical use of the depth buffer is as follows: When an object, such as a triangle, is rendered, OpenGL determines which pixels need to be drawn and computes a measure of the distance from the viewer to each pixel image. That distance is compared with the distance associated with the former contents of the pixel. The lesser of these two distances determines which pixel value is saved, because the closer object is presumed to occlude the farther object. To better appreciate the elegance and simplicity of the depth buffer approach to hidden surfaces, we consider some alternative hidden surface methods.
