True Anaglyph

I don't know why this kind of Anaglyph is called a "True Anaglyph," but that's what I found in my research, and that's what I am calling it here. It isn't my favorite but it solves some of the problems with the Bitmask Filter Anaglyph.

Start with these right and left images:

/images/camera3D/true_anaglyph/fourcubes-left-component.png/images/camera3D/true_anaglyph/fourcubes-right-component.png

Filter each image. For this Generator, all colors are mapped to a shade of red or a shade of blue.

/images/camera3D/true_anaglyph/fourcubes-left-component-modified.png/images/camera3D/true_anaglyph/fourcubes-right-component-modified.png

Add the two images together, yielding:

/images/camera3D/true_anaglyph/fourcubes-composite.png

Add finishing touches to the result with the postDraw method:

/images/camera3D/true_anaglyph/fourcubes-final.png

With red-cyan 3D Glasses this looks better than the bitmask generator but still isn't all that great. It does do a better job with primary colors, and for grayish images, it looks reasonable.
