Re: How can I 'merge' or copy a depth buffer - I can't seem to get it with 'readpixels'?

Just found this: http://devmaster.net/forums/topic/14542-webgl-shadow-maps-and-hackery/

Will give it a go.

Found a simpler solution (thanks to somone on the webGL IRC channel) - as most browsers support float textures now, I just rendered the depth to the alpha channel. No need to pack values into separate buffer.
