array	rotate_coord (const array &vertices, const unsigned axis, const float theta)

Detailed Description

The C++ interface for rotate wrapper for affine transformations.

The rotation wrapper for affine transforms takes as input the vertex array as in the transform_coord function, an axis about which to rotate the coordinates (0 = x, 1 = y, 2 = z) and the angle in radian to rotate the coordinates.

The wrapper creates a transformation matrix and computes the homogeneous transform. The array of rotated coordinates is returned.

Function Documentation

array af::rotate_coord	(	const array &	vertices,
		const unsigned	axis,
		const float	theta
	)

Parameters

[in]	vertices	array of vertices
[in]	axis	coordinate axis to rotate about (0 = x, 1 = y, 2 = z)
[in]	theta	rotation angle in radians

Returns: array of vertices rotated by theta about the axis

Note: to rotate about a different vector (other that x, y, z axes), create a transformation matrix and use the affine function
