WebGL Terrain Flyover Demo • Hacker News Board

Very cool. Are you using occlusion queries for the lens flare sprite? This something I implemented recently in my engine. Eventually I want to do something like this... http://john-chapman-graphics.blogspot.com/2013/02/pseudo-len...

> lens flare is ubiquitous in photography, hence its absence in a computer generated images can be conspicuous

wait, what? Lens flare is not common in photography.

Looks nice but runs at awfully slow 4-5 fps on my Ubuntu 64bit system. Is Radeon HD 4200 to weak for WebGL or is there something you need to configure?

I think it's an issue with hardware acceleration on Linux :(

Runs super smooth 60 fps on my Thinkpad with Nvidia Quadro 2000 on Windows 7. Very well done.
