I’ve just uploaded a mp4 showing a real “redeye” flash as the camera hits the correct angle. This isn’t physically perfect as I am not going for perfect realism here, only showing the technique. With just a little adjustment this could be made physically correct.
Thanks for this, you’re very helpful I’ll be giving this a try, I think with added reflection parameters that cause that sudden ‘glow’ like effect under the particular angle of view and light is the gist of what I’m looking for.
As I mentioned to Chohole the video link she shared: http://www.youtube.com/watch?v=IluS3ItK8d4 made by Dave, appears to be exactly what I’m going for. Largely because the eye of say a cat for example isn’t always illuminated, it’s a natural phenomenon that occurs only under direct lighting and with the correct angle of view… some may say a darkish environment may also be required.
That said though, I love the concept of what you’ve done! Technically speaking, you have added the actual anatomical feature of tapetum lucidum (layer of tissue within the eye that causes the light to reflect back through the retina, causing eye-shine), which is NOT to my knowledge something that is in the ‘as is’ genesis eye. So well done
I’ve attached some images of tapetum lucidum, so that everyone knows what I’m talking about. Also the science behind human red eye since you showed interest in that too
