What steps will reproduce the problem? 1. Open the app. 2. The force-close window appears, while on the background the app's GUI shows up, but the sphere doesn't.

What version of the product are you using? On what operating system? Motorola Defy, stock Eclair (2.1)

I've looked at the req. for this app. Moto Defy is running android 2.1, with OpenGL ES 1.1, so the tehnical specs match. Merry Christmas, I hope to see your app being able to run on Defy too, as a 3D modeling/sculpting app is what I've wanted for myself since I have Android

Based on your description and the error reports i got from the market, it looks like a memory issue, ie one of the main trouble i had while developing truesculpt. Let me explain : even if an Android device has 512Mo of RAM, for one strange reason Android will only let you use 16Mo or 24Mo for each individual application (depending on your device/manufacturer).

The problem is that sculpture is a pretty memory hungry activity and it is difficult to optimize for both speed and memory efficiency. The app is frequently reaching limits and i have to dynamically strip history to remain inside the 24Mo allowed RAM.

If my guess is right, the harcoded device dependent application memory limit of the Defy must be smaller (16Mo) than the one of the Samsung Galaxy S (24Mo) which is the only one i tested before releasing (and where it works correctly).

To test my hypothesis and try to solve your problem, i will send you by mail a modified truesculpt version with a much smaller initial mesh (less subdivided). The sculpture will be more coarse and ugly (5000 triangles instead of the 20000 initial default) but it should work , otherwise i'll have to find another idea ;-)

The pb is that i can only do this when i'm back from my christmas holidays and can reach my good old home dev computer, this means not before the 3rd of January. Sorry you'll have to wait a little.

The only true workaround seems to develop in native C++ using the NDK instead of using Java, so i can allocate more memory, but i won't do this since this means starting from scratch and using a more difficult language/toolchain.

Happy holidays, regards, Fabrice

Thank you for the fast response. I no longer need help as I changed the phone with a lg optimus hub, which gives truesculpt enough memory to run :) However, it would be wonderful if I could also test it on Defy.

Also, even if NDK is much harder to use than SDK, consider the speed and the features you could add to your already marvelous app.

Happy holidays, Thank you for this really awesome code, Alex

PS: is there any way you could also make a subdivision modeler? :D Android really lacks 3D modelers, we're really lucky with your sculpt app.

I'm happy you got a brand new phone and could enjoy truesculpt in good conditions. It's always nice and encouraging when people likes what your doing.

As I got no real workaround for the defy and I can't test easily (no device), I will temporarily exclude this device from the market for this app. This will prevent other persons from being disapointed. Meanwhile, I'll try improve my OutOfMemory exceptions handling (both for RAM and GPU memory).

About the NDK, I didn't used it because my day job consists in working with C++ (in a very different application domain), I know it very well but I wanted to train to a more fun and recent langage/framework like java and the android SDK. I know this is probably a bad technological choice for this kind of demanding application but I wouldn't have started this project otherwise.

I already tried to integrate dynamic subdivision to the project but I discovered the memory issues at this moment and this prevented me to go further and integrate this into the release. Maybe I'll find a way to do this more efficiently and have some time to code it. The purpose of the project is not to mimic a real complete 3D modeler (where desktop version are way more precise and efficient), but rather to try to feel the fun part of sculpting on a portable device.

This project is very young and uncomplete (published 1 month ago), but as it is opensource, if you want to try to modify or add features, I would happily integrate your changes to the source code and publish them (after a carefull review ;)). Any help is welcome !(see here https://code.google.com/p/truesculpt/wiki/HelpNeeded).

And thank you for updating your (previously bad) comment on the market, I appreciate it!

Regards, Fabrice

I am not good at programming, just an intermediate highschool C++ programmer. Instead, I'll try making some tutorials, and post some things.

I'll send you everything on email/the gallery :D

Hello I am Spanish sculptor and would be interested in participating in the project developing sample models
