Snow Effect in Google+ Photo

I didn't know Google+'s Auto Awesome mode does snow effects too. It was a pleasant surprise to find out what it did to a picture I took recently. It would make a good x-mas card :)

Blendable RGBM

What is RGBM? Using a fat buffer(16 bit-per-channel) is the most intuitive way to store a HDR render target, but it was too slow and it used too much memory, so we decided to encode(pack) it into a 8 bit-per-channel buffer. There are different packing methods, but I believe the most widely used method was RGBM. (also this link has a nice summary of LogLUV too, so give it a read if you are not familiar with this topic at all)

Mipmap Quality

So mipmaps are often blurry and artists think we are bunch of morons making their awesome artwork so blurry.. :-) You know, most of the time we see lower mips all the time in the game. It depends on camera settings, but I found it's very rare that we see highest mip in most of the games out there.
