Function Documentation

static void CC3Mat4Multiply	(	GLfloat *	mOut,
		const GLfloat *	mL,
		const GLfloat *	mR
	)		[inline, static]

Multiplies mL on the left by mR on the right, and stores the result in mOut.

• mOut is 4x4 matrix
• mL is 4x4 matrix
• mR is 4x4 matrix

static void kmMat4RotationQuaternion	(	GLfloat *	m,
		const CC3Vector4	q
	)		[inline, static]

Builds a rotation matrix from a quaternion to a rotation matrix, stores the result in pOut and returns the result.

static void kmMat4RotationX	(	GLfloat *	m,
		const GLfloat	degrees
	)		[inline, static]

Builds a rotation matrix around the X-axis, stores the result in pOut and returns the result.

static void kmMat4RotationY	(	GLfloat *	m,
		const GLfloat	degrees
	)		[inline, static]

Builds a rotation matrix around the Y-axis, stores the result in pOut and returns the result.

static void kmMat4RotationYXZ	(	GLfloat *	m,
		CC3Vector	aRotation
	)		[inline, static]

Builds a rotation matrix that rotates around all three axes, y (yaw), x (pitch) and z (roll), in that order, stores the result in 4x4 GL matrix m and returns the result.

This algorithm matches up along the positive Y axis, which is the OpenGL ES default.

static void kmMat4RotationZ	(	GLfloat *	m,
		const GLfloat	degrees
	)		[inline, static]

Builds a rotation matrix around the Z-axis, stores the result in pOut and returns the result.

static void kmMat4RotationZYX	(	GLfloat *	m,
		CC3Vector	aRotation
	)		[inline, static]

Builds a rotation matrix that rotates around all three axes z (roll), y (yaw), and x (pitch), in that order, stores the result in pOut and returns the result This algorithm matches up along the positive Z axis, which is used by some commercial 3D editors.

static void kmMat4Transformation	(	GLfloat *	m,
		const CC3Vector	aTranslation,
		const CC3Vector	aRotation,
		const CC3Vector	aScale
	)		[inline, static]

Builds a transformation matrix that translates, rotates and scales according to the specified vectors, stores the result in pOut and returns the result.
