bool invertMatrix	(	const float *	matrix,
		float *	inverse
	)

Finds the inverse of a matrix.

Parameters:

the	input 4x4 column-major matrix following OpenGL's format
the	output 4x4 column-major inverse matrix following OpenGL's format

Definition at line 109 of file apps/point_cloud_editor/src/common.cpp.

void multMatrix	(	const float *	left,
		const float *	right,
		float *	result
	)

Performs result = left * right.

Parameters:

left	A pointer to memory representing at least MATRIX_SIZE elements
right	A pointer to memory representing at least MATRIX_SIZE elements
result	A pointer to memory representing at least MATRIX_SIZE elements. The output of left * right is stored in this matrix

Precondition:

Assumes all pointers are valid.
