OpenGL® ES support?

#1

Hello,

i read about OpenGL® ES, and i’m a little bit confused…
is it an opengl-based api?
can jogl support it?

Thanks…

#2

afaik, ES stands for embedded systems.

like “normal” openGL it is an API specification for an implementation of the openGL library targeted for handheld devices.

you can read about it here:

THanks,

what if, i have to use OpenglES 2.0? i haven’t found an implementation but for 1.0(fixed pipelines).
using gluegen, could it be easy?

#4

I’m curious what 2.0 hardware you have access to? I didn’t think anyone was near ready with PowerVR SGX parts, ATI/BitBoys G40 and Imageon parts are also a little ways out. I think PS3 is probably the closest to available.

#5

I read, that PS3 will support OpenglES1.2 + CGs…

My question was theoratical actually. :slight_smile:

on the JSR 239 page ( http://jcp.org/en/jsr/detail?id=239 ), i read this:
“much of the work derived from JSR 231”
So, this package is built on JOGL?

#6

No, unfortunately the JSR-231 and JSR-239 APIs are somewhat different. For one thing, JSR-239 explicitly exposes the EGL APIs, where JSR-231 abstracts away the differences between the WGL/GLX/Mac OS window system APIs.

I think it would probably be pretty easy to use GlueGen to produce most of a JSR-239 implementation, but I haven’t tried this myself.

#7

Thanks, Ken!

i was very concerned, i read papers and articles all day, and i saw suspicions about Sony PS3 software technology. They talked about a Java VM in the linux OS in PS3.
Have You any information about this? Will it a JSR 239 implementation?

#8

That’s very interesting. Where did you read that? I haven’t heard anything about Java on the PS3 though I think having a JVM there would be very interesting.

#9

i read it in several articles. for example:

Right, I should have known that since there is a Java component to the Blu-Ray specs and of course the PS3 is going to support Blu-Ray. However, I haven’t heard anything about whether there will be a JSR-239 implementation available for applications. That JSR isn’t part of the official Blu-Ray specs.
