bool icMatrixInvert3x3 (  icFloatNumber *  M  ) 
 

Name: icMatrixInvert3x3

Purpose: Inversion of a 3x3 matrix using the Adjoint Cofactor and the determinant of the 3x3 matrix.

Note: Matrix index positions: 0 1 2 3 4 5 6 7 8

Args: M = matrix to invert.

Return: true = matrix is invertible and stored back into M, false = matrix is not invertible.

void icMatrixMultiply3x3 (  icFloatNumber *  result,
const icFloatNumber *  l,
const icFloatNumber *  r
) 
 

Name: icMatrixMultiply3x3

Purpose: Multiply two 3x3 matricies resulting in a 3x3 matrix.

Note: Matrix index positions: 0 1 2 3 4 5 6 7 8

Args: result = matrix to recieve result. l = left matrix to multiply (matrix multiplication is order dependent) r = right matrix to multiply (matrix multiplicaiton is order dependent)

Name: icVectorApplyMatrix3x3

Purpose: Applies a 3x3 matrix to a 3 element column vector.

Note: Matrix index positions: 0 1 2 3 4 5 6 7 8

Note: result = m x v

Args: result = vector to receive result. m = matrix to multiply v = vector to apply matrix to

void icXyzFromPcs (  icFloatNumber *  XYZ  ) 
 

Here are some conversion routines to convert to regular XYZ encoding.

Floating point encoding of XYZ in PCS is in range 0.0 to 1.0 (Note: X=1.0 is encoded as about 0.5)
