This is a question for the experts.
I'm on a BB storm JDE 4.7.0
I've looked through the BB storm's API's and I cannot find any support for 3D, OPENGL or anything like that when I believe support for this is in the Qualcomm chipset's GPU.
Whats the current "stance" on this at RIM and/or what are the future plans.
I may need this for a future product related to Scientific visualization (3D surfaces and possible other solutions). I'm also sure that games developers need it.
Solved! Go to Solution.

If you see my link and questions from earlier, I used SVG for rendering sphere collections. Apparently they
have a gradient function so you could come close on brightness profile but I'm not sure
how flexible that really is ( I thought I could just change the parameters and move the illumination
source and get something like lambertian surface but it wasn't obvious how to get this).
In any case, this question finally pushed me to do what I started the other day and download several rim
pdf guides, convert them to text ( extract the information, the stuff you care about ) and then make them
searchable in arbitrary ways ( I guess I'm also reacting to a concern that at least one important source has
recently published "source code" for an information application that is heavy into artwork and includes windoze
DLL's for which there may be no vendor-neutral true source code).

· JSR 226: Scalable 2D Vector Graphics API for Java ME
After a few more lines of text processing, I came up with this list of JSR's referenced in the documents SOMEWHERE.
I think RIM does have a web page that probably contains a more accurate list but you get the idea if you want to
find something the web designer didn't anticipate, there are ways of getting it,

This is the chip datasheet in the Storm...Qualcoomm 7600. I also think it's in the BOLD. The GPU has the capability of processing something like 4M polygons per second in 3D.

Seems like a good match to java, the JVM can probably execute 4M byte codes per seond (LOL).
Just kidding, I don't really know, but without the right API's it is difficult to make good use
of any underlying hardware as you need some kind of native support that can keep up.

Actually, the CPU supports the ARM Jazelle Java accelleration, so it's very efficient. I think the CPU speed is 400MHz (ARM11) and there is also an ARM9 at 230MHz or something.
The guys who are supposed to be implementing the java API (such as OPENGL and other features for 3D) should be RIM and their VM partners. I'm pretty certain that they don't use their own VM. They probably use a standard one (recommended by qualcomm) and have extensions that they just add to it. I know this because I ran the SW team on a similar product for driving flat panel displays for monitors and whatnot once apon a time. You try to buy what you can to get you to market as fast as possible and keep your engineers focused on their core competencies while having stuff that is not your core competency being done by an external company. They may actually get the VM and chip together with base OS all from qualcomm, and probably a big chunk of the hardware integration is done by qualcomm in order to get the deal (since it's worth so much to qualcomm).
Anyways, I digress :-)
What I'm still wondering is where is the java API to access the wonderful features of their GPU's 3D processing.

To all I noticed this post was a year ago. I would like to know if BlackBerry RIM supports JSR 184 or JSR 239 for BB OS 5.x. My BB Curve 8530 uses OS5.x.
Does it now support it or not?
03-13-2010 11:25 PM
Maybe, OS 5.0 supports JSR 239 but RIM seems to only be supporting BlackBerry's with a GPU (The "Storms", more specifically: Storm 2. Technically Storm 1 has a GPU but RIM said there were some hardware changes to make 3D work on the Storm 2 but it means it won't work on the Storm 1).
The easiest way to check is to simply make an app that calls GLUtils.isSupported() and see if it returns true. Note: Make sure you do this on the actual device, not the simulator.
