Detailed Description

A projection field returning the result of a matrix multiplication with perspective division on the source field vector.

A projection field returning the result of a matrix multiplication with perspective division on the source field vector. The source_field vector is expanded to a homogeneous coordinate by appending a component of value 1, which is multiplied by the projection_matrix_field, and the extra calculated value resulting from the unit component is used to divide through each of the other components to give a perspective projection in the resulting field. The projection_matrix_field must have have a multiple of (source_field->number_of_components + 1) components forming a matrix with that many columns and the resulting (number_of_components + 1) rows. The first values in the projection_matrix are across the first row, followed by the next row and so on. Hence a 4x4 matrix transforms a 3-component vector to a 3-component vector: [x'] = [m1 m2 m3 m4 ][x] [y'] = [m5 m6 m7 m8 ][y] [z'] = [m9 m10 m11 m12][z] [h'] = [m13 m14 m15 m16][1] The resulting field returns 3 components [x'/h', y'/h', z'/h']
