If you rendered the cube using triangles instead, how many triangles would be needed? 5 but render the cube using two quad strips, each containing three quadrilaterals. 5 but render the cube using two triangle fans. 3 Double Buffering for Animation The term “animation” refers to drawing moving objects or scenes. The movement is only a visual illusion, however; in practice, animation is achieved by drawing a succession of still scenes, called frames, each showing a static snapshot at an instant in time.
In this stage, a 3-D model of the scene to be displayed is created. This stage is generally the main portion of an OpenGL program. The program draws images by specifying their positions in 3-space. At its most fundamental level, the modeling in 3-space consists of describing vertices, lines, and polygons (usually triangles and quadrilaterals) by giving the x-, y-, z-coordinates of the vertices. OpenGL provides a ﬂexible set of tools for positioning vertices, including methods for rotating, scaling, and reshaping objects.
14 Let M = (u, v, w) be a 3 × 3 matrix. Prove that det(M) is equal to (u × v) · w. 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.
