Class AdditiveSubtractiveLight
This example tests various color combination capabilities, and also demonstrating that filtering (negative colors) are not supported in the X3D/VRML color model. Discussion follows. There are 2 ways to combine colors: Additive (e.g. a TV screen, overlapping spotlights, or pointillist art), for example [red + green = yellow] [1 0 0 + 0 1 0 = 1 1 0]. Subtractive (e.g. mixing paints or stacking filters), for example [white background + yellow filter + cyan filter = green] [1 1 1 + 0 0 -1 + -1 0 0 = 0 1 0].

This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet
(version control)
which is used to create Java source code from an original .x3d
model.
