Failed build process for windows

[Srikar Palempalli]

Downloaded Cygwin ,XML parser as mentioned in build process.
After installing cygwin and trying to run "tar xvzf XML-Parser-2.34.tar.gz"command
i am getting following errors
bash-2.05b$ tar xvzf XML-Parser-2.34.tar.gz

C:\Cygwin\bin\bash.exe: heap allocated but not at 0x1CD0000
14014013 [main] bash 2220 sync_with_child: child 7776(0x1F4) died before initial
ization with status code 0x1
14014177 [main] bash 2220 sync_with_child: child state waiting for longjmp
bash: fork: Resource temporarily unavailable
bash-2.05b$

I installed cygwin on windows 8 OS...
Any thing to take care of while installing on windows 8.

I'd suggest to use my repack and CMake.
I repackaged it for CMake since I disliked the native build system.

thank you. repacked version works pretty great

I am trying to parse .u3d file and retrieve vertices.
I am able to to retrieve vertices if .u3d file is saved as base mesh
Unable to retrieve vertices if .u3d file is saved as clod mesh.
Any pointers along that direction are greatly appreciated

Saved by what software?

[Srikar Palempalli]

repacked version from mathgl library

[Srikar Palempalli]

saved by HelloWorld sample provided in u3d project

Sorry my question is not clear

I am using the u3dparser in samples provided in u3d project to parse .u3d file and retrieve vertices.
I am able to extend functionality for block 0xFFFFFF3B and retrieve vertices if .u3d file is saved as base mesh
I am unable to extend functionality for block 0xFFFFFF3C and retrieve vertices if .u3d file is saved as progressive mesh.
Based on my research through internet I understood progressive mesh parsing need a context which needs to be provided to progressive mesh block to extract tessellation data... I am not sure about what is context that needs to be passed.
Hope my question is clear now

Thanks for the help

Sorry, I can not help here much.
My only interest was in IDTF=>U3D conversion.
I tried not to work on native U3D level and I have already wiped out from my memory everything I learned accidentally.
Do you know that U3D library is not only for writing, but also for loading and rendering U3D files? Look at the player sources in the original Intel archive.
You may try to trace the loader or just look at the sources to see how it works.
u3dparser is an alternative way to "disassemble" U3D files directly, but it looks to be a parallel effort to the main library and may lack functionality.
The other possible problem is that Adobe got some proprietary compression algorithm (extension for U3D) from Right Hemisphere, so many real world U3D files may be unreadable by Intel software. The are the docs for that extension, but, as far as I remember, no sample code.

THanks for the info Michail..
I will definitely look into that
