Function Documentation

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.

Definition at line 54 of file apps/point_cloud_editor/src/common.cpp.

void setIdentity

(

float *

matrix

)

Sets an array representing a 4x4 matrix to the identity.

Parameters:

matrix

A pointer to memory representing at least MATRIX_SIZE elements

Precondition:

Assumes the pointer is valid.

Definition at line 46 of file apps/point_cloud_editor/src/common.cpp.

void stringToLower

(

std::string &

s

)

Converts the passed string to lowercase in place.

Parameters:

s	The string to be made lower.

Definition at line 240 of file apps/point_cloud_editor/src/common.cpp.

template<typename T >

void toString	(	T	input,
		std::string &	result
	)

Helper function for converting objects to strings (using operator<<)

Parameters:

input	The object to be converted
result	A reference to the string where the resulting string will be stored.
