I'm trying to port one of my OpenGL/Glut programs over to Android 1.6. I used GLut extensively due to my classes teaching glut. Is there an alternative to glutTimerFunc or replacement for using glutTimerFunc? Also, any ideas where I can replace glutMainLoop? From looking at a few examples, onDrawFrame what I should be looking at?

i'm doing some experiments with OpenGL using the GLSurfaceView introduced in 1.5 In my Renderer I keep track of the time spent to render the last frame and pass this value to the method that update my model. The goal is to keep objects movements on the screen independent from the rendering time. Now this seems to work perfectly in the emulator, but on the real device is at least 4/5 times slower! Has anyone experienced the same problem? Or, anyone has a clue of what I'm doing wrong? Here's pieces of the code I'm using
View 3 Replies View RelatedSingle Threaded OpenGL game ! (check bottom, you can download and use the helper class) Lighting disabled ! Depth Buffer disabled ! Culling enabled ! Textures disabled !
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?
Is there any simple application that can track how many step I walked. I don't want the one that uses gps. Just make use of the accelerometer i guess? I have this application when i use my old C905.

View 4 Replies View RelatedI rooted my phone with the help from this forum. All went well. My phone started off a stock unmolested 2.1 version with update 1 and ESE81 and in about an hour, I was wirelessly tethered to my laptop and on the internet. A lot of this was copied and pasted from Fabolous' threads, so props to him. Before you do anything, make sure to copy your contacts to your SD card and anything else you are afraid to loose. The first section won't erase anything, but second section will. Some of these steps may not be needed, but these are just the steps I took, and it worked.
These are the steps:
1.) Download SPRecovery_ESE81.sbf to your C: root directory (C:)
2.) Download md5sum
3.) Place md5sum in c:windowssystem32.....
So I am trying to flash the WW rom and i can flash it just fine and everything works like it should but i had to wipe obviously to flash it, when i do a Nand Restore, it restores to the EE 3.0 rom i'm coming from. Can someone tell me when i'm supposed to restore? Should I wipe and then flash the rom, and THEN restore? Or should I wipe restore then flash the rom? I'm confused on the process i guess.

View 1 Replies View RelatedSo I rooted a few days ago using Universal 1 Click Method and flashed Xxtrasense ROM immediately (in step 4 of the instructions below).
Step 1) download and install this APK:
http://dl.dropbox.com/u/8699733/erisone010.apk - VERSION 0.1.0
Step 2) Run, read disclaimer, press button
Step 3) Reboot, once rebooted your phone should have Amon's recovery. Yay.
Step 4) Use the recovery to flash rootme.zip that is now on your SDCard, or the custom rom of your choice.
Step 5) Go into settings, and turn usb debugging on. After you have root, please uninstall this app.
I want to try new ROMs and have read through a number of threads but its only confused me more on the next steps. Questions are:
1. Do I need to do a NAND or NAND+ext backup (I've done a NAND back up shortly after flashing the Xtrasense ROM)?
2. Is Titanium Backup the only way to get my Apps and data transferred to any new ROMs I flash?
3. At what point is a dalvik wipe required?
If someone is able to provide a step-by-step outline (similar to jcase's 1-click eris root noted above).
What steps do i need to follow to connect my phone to the computer?
i want to access my SD card.
the only disk that came with the phone is VZ access manager but when i installed it i could not locate the SD card.
On your HTC EVO 4G, go to Settings > Language & keyboard > Touch Input > International keyboard and check the box in the screen shot attached. Now go into the app that you want to type the degree symbol in and use the microphone key with the EN underneath to access the degree symbol. Go to 12# > 1/3 and you will see a degree symbol, along with the degree C & degree F symbols.
