Color Matrix multiplies the RGBA channels based on the values entered in a 4 x 4 grid. The fifth
column/row is an Add column.
Update Lock
When this control is selected, Fusion does not render the node. This is useful for setting up
each value of the node, and then turning off Update Lock to render it.
Matrix
This defines what type of operation actually takes place. The horizontal rows define the output
values of the node. From left to right, they are R, G, B, A, and Add. The vertical columns define
the input values. From top to bottom, they are R, G, B, A, and Add. The Add column allows
simple adding of values to the individual color channels.
By default, the output values are identical to the input values.
1.0 means 100% of the Red channel input is copied to the Red channel output.
1.0 means 100% of the Green channel input is copied to the Green channel output.
1.0 means 100% of the Blue channel input is copied to the Blue channel output.
1.0 means 100% of the Alpha channel input is copied to the Alpha channel output.
Written as mathematical equations, the default settings of the matrix would appear as follows:
[R out] = 1 * [R in] + 0 * [G in] + 0 * [B in] + 0 * [A in] + 0
[G out] = 0 * [R in] + 1 * [G in] + 0 * [B in] + 0 * [A in] + 0
[B out] = 0 * [R in] + 0 * [G in] + 1 * [B in] + 0 * [A in] + 0
[A out] = 0 * [R in] + 0 * [G in] + 0 * [B in] + 1 * [A in] + 0
Invert
Enabling this option inverts the Matrix. Think of swapping channels around, doing other
operations with different nodes, and then copying and pasting the original ColorMatrix and
setting it to Invert to get your channels back to the original.
