We don't use Penumbra. On Java, we use JOGL, and on other targets we use pure OpenGL or OpenGL ES API for both compatibility and performance reasons. We have to ensure whatever OpenGL stuff we do, will work everywhere. > > What do you mean by "battery concerns"? Laptops, Mobile devices and such. If you use OpenGL on a laptop, it will use the GPU assuming it's hardware accelerated. GPU is a big battery drain. On mobile devices such as iPhone and Android, it's even more so. Using OpenGL unnecessarily causes battery drain on your hardware. Plus, if you use OpenGL, and your target is using those Intel Extreme Graphics, where the only thing it's Extreme at, is Extremely slow. :) You end up gain nothing but lose lots. -- Omnem crede diem tibi diluxisse supremum. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
