Hello!


I've got some questions about Opengl ES


First, what is the version of Opengl es on the pandora?


Second, can I develop with Opengl es and test it directly on my computer (64bit)?


Third, are there graphics engine in C++ for the pandora?


Thanks!
 
1) The Pandora has OpenGL|ES 1 and 2.


2) There is a pvr gles sdk iirc.


3) There are some graphics engines like Sparrow 3d (not using opengles), Penjin, There is wavebreaker, which is an expandable gles examplegame and of course quake 1,2 and 3 engines and Darkplaces etc. run on the Pandora with gles support.


, have a look into the development section and the wiki: pandorawiki.org.

The more recent OpenGL specifications have an OpenGL ES compatibility profile that might be usable for that.


It would be much easier using a Linux system with Gallium drivers for your video card, there are OpenGL ES 1.0 and 2.0 implementations for Gallium so you can directly compile against it and test it right away.
 
You can test ES code on desktop versions of OpenGL. For 1.X there are only a couple slight naming variations and 2.X is a subset of the full versions. Really if you take the time to restrict the API you use then you can test with just about anything.
