What's going on with isgl3d? Is it still alive?

[cometlinear]

Hey all,

I've been using isgl3d in limited capacity since the very beginning. Obviously, it hasn't been actively developed in quite some time.

Is *anyone* out there even considering taking an active development role? Does anyone have a good development version?

This is an excellent lightweight 3D framework and it would be a real shame to see it die. I've used quite a few 3D engines and this is truly one of the better ones.



Sincerely,

I have been using it actively. I have even upgraded it to Xcode 5.0. I can submit the upgrade on GitHub in a separate branch if I get access.

Do the templates work on XCode 5 as well?


Thanks!

Yes. I have been able to compile for my app: myPath-3D on iTunes app store. However, it turns out that I didn't update the latest isgl3d for this. Here is the fork I am working on:

https://github.com/VoyaGenius/isgl3d

Its giving me these two compilation errors in matrix_impl.m:

unknown register 'r0' in asm. Anyone knows how to fix this?

Ok folks, those waiting for an update: I did manage to resolve build issues for latest Xcode. I have pushed it to the fork: https://github.com/VoyaGenius/isgl3d and created a pull request.

It might have some issues. I would like the Developers/authorized to peer review the code as the neon instructions have changed.

Hi all,

I am using isgl3d framework for displaying .pod 3D file on ipad application.

Application working properly with iOS 6 but its get crashes with Xcode 5  at glDrawElements in Isgl3dGenericShader file.

I replace my code with updated files done by Harish .

But still getting crash at glDrawElements. 

Its works fine while launching  first .pod file but when I cal another .pod file its get crash on glDrawElements.

 Bt same code works fine with ios6.

Pls pls reply for my problem.

Thank u in advance.

Hi Harish,

can you pls help me for the crash issue on glDrawElements in xcode by ios7 sdk.

My glDrawElements method is as follows:

glDrawElements(GL_TRIANGLES, numberOfElements, GL_UNSIGNED_SHORT, &((unsigned short *)0)[elementOffset]); 

its work properly for calling first 3D model. But gets crash when i call another 3D model. 3D model is in format .POD file

Its work properly for ios 6 and below.

pls reply.

Thanks,

Bhavana

when I put constant value for "numberOfElements" its not get crash, but model not display properly.

Pls give some suggestions.

Has anyone gotten this to work with iOS 8.x ?

I have a project that was working with iOS5 and iOS6 and now I'm getting back to it with iOS 8.3. Having linker errors so I downloaded Harish's version and I'm trying to get it to compile. Had to put in a couple of explicit includes of ES3 and now I have some Linker errors

I'm trying to compile Harish's version with iOS 8.3 and getting linker problems -- see below. Has anyone compiled this for iOS 8.x?  I did have to add a few explicit includes of ES3 but I think if I can figure this Linker issue out it should be OK.
