I am working on a app which render geometrics with VBO in NDK opengl, it works in other phone, but in Motola Droid, it will cause the devices reboot.
The logs like next.

Just 176 integers (x,y values only) making 88 vertexes along with 132 index numbers making "44 triangles only"
Framerates I get is
with GL_BLENDING disabled - 145 fps approx only! enabled - 110 fps approx only!
I have the screenshot of exact code in the draw function here.. just 2 damn lines ! I have hidden only the comments.. click here to see it http://prasna991.googlepages.com/drawframe.png
variable details in the 2 lines of code =========================== ipts = 176 elements (only x and y for each vertex) totallinetriangles * 3 = 176 lineindexes = 132 elements - type "short"
Here is the screenshot of output drawing and how it will look like http://prasna991.googlepages.com/screen.png
OpenGL single threaded Initialization Helper ================================ Here is my OpenGL helper class.. makes the OpenGL initialization for newbies a cakewalk http://prasna991.googlepages.com/OpenGLHelperclass.txt
I tested by rendering on the touch event only.. frame rate drops only when u touch and drag and here I have just tested by tapping and releasing gently on the emulator and on the device
Is this the device limitations ? So graphics is actually a lot lot lot slower than on iPhone ?
I would like to be able to use the OpenGL API from both Java and C (via NDK).
In Java, there is a GL object passed, which has all GL methods on it.
In C, you just talk to the native library.
In a single onDrawFrame callback (for which Java is passed a GL), can I use methods on the GL object, and also call NDK methods which access the openGL library?
In other words, is the GL object just a wrapper for the same instance of the native library?
I am often using my Android browser when I come across a QR code. Is there any way to scan the QR code from within the browser? It seems absurd that I then have load that page on another monitor and then scan that monitor with goggles are barcode reader...

We are getting a SIGSEGV 11 when launching our OpenGL activity. Here is the logcat. It appears to happen on Droid Hardware, but not the 2.0 Emulator. We are trying to do some testing to see if we can slowly build up some code to cause a crash.
CODE:....................
I ran into a rather strange problem with my OpenGL game. While most textures look good, five or six are not drawn on Droid, and I don't see anything special about these images/models. For example, my HUD is made of 4 elements. The upper part is drawn correctly, while the lower part appears as white rectangles. The code used for loading and drawing these models and textures is exactly the same. Textures are 32-bit TGAs in both cases, POT dimensions, in - nodpi, inScaled==false, using GLSurfaceView to rule out configuration issues. No problems on G1 and Hero (and of course on emulator). And I don't have the Droid, so I can't just try whatever comes to my mind. Asked users to send me logs - no errors, all models and images appear to load normally.

If I understand correctly though the GPU in the Droid 1 is ES2.0 Compliant, so it should have at least 2 texture units, any idea why I'm getting this weird look in my app on the Droid 1?
I just got my hands on this phone.
Here's my summary:
1) It's really fast. Runs all my games at max framerates.
2) The screen is 16:9 and will probably mess with your layouts and games and stuff.
3) It has a PowerVR SGX530. That's right around iPhone 3GS's GPU speed.
I believe the hardware supports OpenGL ES 2.0 but since Android doesn't, there's no way to use it right now. I did, however, dump all of the GL extensions and put them alongside the G1 and Emulator extension lists into this handy-dandy article - http://www.rbgrn.net/content/345-hands-on-motorola-droid-opengl-es-specs

View 4 Replies View RelatedI'm writing a game engine.
I have a little example (see http://qrcode.kaywa.com/img.php?s=8&d=http://rokonandroid.com/rd.apk), that seems to work fine on every device except Droid / Milestone.
It displays a blue screen (due to glClearColor being set to blue), and nothing more.
I have tried with/without textures, and with/without VBOs. Yet still all blue screens on Droid.
What is unique about Droid and how it handles OpenGL, and why is it doing this?
Has anyone found a way to enable antialiasing in OpenGL on any of the Android devices?
View 2 Replies View RelatedCan I assume that, if a phone runs Android 2.0, it also supports OpenGL ES 2.0 and thus the graphic hardware has full support for programmable shaders?
IOW, does Android 2.0 as a platform mandate OpenGL ES 2.0 support? Or is it optional?
Can anyone please recommend a training session/course for Android graphics API/OpenGL ES?
View 1 Replies View RelatedOnce again I'm trying to get into openGL, but as usual I choke when passing around vertices/vertixes/whatever and every little detail can lead to disaster (wrong format, initialization not properly set up, where memory are saved, etc.).
My main goal is to use openGL for 2D graphics to speed up performance compared to regular cpu drawing.
Anyways, my openGL Renderer looks like this code...
With an IndexOutOfBoundsException, but I'm sure there are more problems with the code.
Since both iPhone and Android support OpenGL ES, is there any open source or commercial GUI library we can use for these two platforms? Or is it doable (or how difficult) to port an application from one to another platform?
As I know, for iPhone only, libNUI (http://www.libnui.net) is a good choice (dynamic layout & mature), but it only provides GPL & commercial license. Any other open source tool similar with libNUI?
