Collada Exporter

[inakin]

Hello,

I'm working with BulletColladaConverter. I load a .dae file with ColladaConverter load's method and then I save some snapshots in some moments of the simulation.

The problem is that when I save a snapshot (I use a different file that source file) in the dae file when it inserts a reference to the same file references source document not the document which is writing.

An example of the problem is:

<technique_common>
<accessor count="25" source="file:///datos/universidad/pfc/bullet-2.67/Demos/prueba2/preprocess.daei#Plane-Geometry-Position-array" stride="3">
<param name="X" type="float"/>
<param name="Y" type="float"/>
<param name="Z" type="float"/>
</accessor>
</technique_common>

The source file is preprocess.daei and the file in which is writen this is /home/inakin/p3.dae.

Another problem that I have is when I try to load for example preprocess.dae the converter looks for preprocess.daei file so I have to change the name of the files in order it rules.

Thank you and sorry for my English.

We currently don't support multi-document COLLADA .dae files. Bullet ships with a stripped-down version of libxml: we removed external URI/URL reference support in the libxml version that ships with Bullet, in order to prevent some licensing issues.

Can you try to use a single COLLADA document, without

Code: Select all

<accessor count="25" source="file:///datos/universidad/pfc/bullet-2.67/Demos/prueba2/preprocess.daei#Plane-Geometry-Position-array" stride="3">

but instead, just referring within the file like this:

Code: Select all

<accessor count="25" source="#Plane-Geometry-Position-array" stride="3">

Alternatively, please use a full version of libxml.

Another problem that I have is when I try to load for example preprocess.dae the converter looks for preprocess.daei file so I have to change the name of the files in order it rules.

This could be a bug, we need to check it out.
Hope this helps,
Erwin

I just use the save method giving a filename as parameter and the Collada Converter done the reference to the file other file. The problem is this:

I load the prueba.dae document. Then I save the Simulation in the p3.dae file. In the p3.dae file appears the references to the prueba.dae document. I only load from one document and save in another document.


Thanks

We just fixed some of the Bullet Collada Converter issues.

Can you try out the updated (new) Bullet 2.67 file from googlecode?
