In linear algebra a rotation matrix is a matrix that is used to perform a rotation in Euclidean vectore.For example using the convention below the matrix [ ] rotates points in the xy-plane counterclockwise through an angle about the origin of the Cartesian coordinate system.To perform the rotation using a rotation matrix R the position of each point must be represented From Eulers rotation theorem we know that any rotation can be expressed as a single rotation about some axis. The axis is the unit vector (unique except for sign) which remains unchanged by the rotation. The magnitude of the angle is also unique with its sign being determined by the sign of the rotation axis.Mastering the rotation matrix is the key to success at 3D graphics programming. Here we discuss the properties in detail.

Rotation Matrix. When discussing a rotation there are two possible conventions rotation of the axes and rotation of the object relative to fixed axes.. In consider the matrix that rotates a given vector by a counterclockwise angle in a fixed coordinate system. Then8.4. The initial coordinate system. For the outermost svg element the SVG user agent must determine an initial viewport coordinate system and an initial user coordinate system such that the two coordinates systems are identical. The origin of both coordinate systems must be at the origin of the SVG viewport and one unit in the initial coordinate system must equal one CSS 2.1 px ([] section matrix. a cairo_matrix_t. radians. angle of rotation in radians. The direction of rotation is defined such that positive angles rotate in the direction from the positive X axis toward the positive Y axis.
