already in work, but it will be only available when also WebGL will be available.
Without WebGL this is technically currently not possible (there is no blendmode=add like functionality for HTML DOM elements).
Klaus, do you really need WebGL to make flare in HTML5. In Flash version you have used krpano_default_flares.jpg and blendmode (I suppose). What about using simple PNG file wih 8-bit transparency channel?
Files are encrypted with the public key (except lensflaresettings.xml). Everything is prepared that there is no need to change anything in the source code.
best regards,
