float * Matrix3::getAsArray

(

)

Get this matrix as an array of values rather than a matrix This pointer is to an array on the stack which will be deleted when this matrix is disposed of.

Returns

A float array containing all the values in this matrix

Matrix3 Matrix3::getInverse

(

)

Returns the inverse of this matrix as a Matrix3.

Returns

A Matrix3 that is the inverse of this matrix

Matrix3 Matrix3::getTranspose

(

)

Returns the transpose of this matrix as a Matrix3.

Returns

A Matrix3 that is the transpoe of this matrix

Matrix3::operator Matrix4

(

)

Operator to convert this Matrix3 to a Matrix4 The resulting vector has all its new values set to 0 except for the last place which is set to a 1.

The new Matrix will be laid out: x1, y1, z1, 0, x2, y2, z2, 0, x3, y3, z3, 0, 0, 0, 0, 1

Matrix3 Matrix3::operator*

(

Matrix3

mat

)

Multiplies this Matrix3 by another given Matrix3 and returns the resulting matrix.

Parameters

mat	The other Matrix3 to multiply into this one

Returns

The product of this matrix * mat as a Matrix3

Vector3 Matrix3::operator*

(

Vector3

vec

)

Multiplies this Matrix3 by a given Vector3 and returns the resulting Vector3.

Parameters

vec	The Vector3 to multiply into this matrix

Returns

The product of this matrix * vec as a Vector3

float * Matrix3::operator[]

(

int

i

)

Fetches a row of this Matrix at the index i The subsequent row can also use this operator so you can access values in this matrix with two [] operators: myMatrix[0][1].

Parameters

i	The index of the row to fetch

Returns

A pointer to a float array which is a row of this matrix This will throw an index out of range exception if you try to access a 4th row with index 3.
