how to clean up a .dae

[dsdsdsdsd]

hello;

I have finally gotten Lightwave 9.6, which has an improved collada exporter ( though I have not decided whether it is worth it or not ... maybe );

I have been using blender for the purpose of collada export until now;

PROBLEM: the .dae produced by LW is about 4 times bulkier than the .dae produced by Blender;

I have been able to identify a lot of the extra and redundant stuff inside the LW .dae, and for the last couple of weeks I have been deleting the extra stuff by hand, inside of my text editor;

but that is tedious, very tedious;


QUESTION: is anyone aware of a script that analyzes/cleansup .dae files to make them PV3D ready?


I am prepared to write an as3-based ( or php-based ... don't know yet ) XML-manipulator, but I have concerns that I do not know the rules of .dae and especially PV3D's DAE class well enough to get it right without a lot of trial and error;




thanks,
Shannon

You're aware of the COLLADA textbook, "COLLADA: Sailing the Gulf of 3D Digital Content Creation" by Arnaud and Barnes? It has a lot of specifics of the COLLADA format, so you may want to see if it's helpful in refining your DAEs.

This sounds like an excellent idea. I had similar plans myself until I was tasked away from working with COLLADA for a while.

I did not know that there was a book; I have looked at the collada website, but it was overwhelming, like learning the DOM, so I ran away with my tail tucked between my legs;

I'll look into it though; as it stands I am charting out all of the differences between my blender.dae and my LW.dae ...

Have you tried COLLADA Refinery
(https://collada.org/mediawiki/index.php/COLLADA_Refinery) it can
optimize DAEs but usually breaks them, so it will be best some with
inner knowledge to write conditioner depending on what should be kept
for using it in Pv3d.

I also use LW9.6 and have noticed some of the extra stuff in the dae  
file. I am not sure about the modeler dae files but here is what I  
have been doing in the layout dae files:

- Using Textwrangler I have created a GREP pattern which goes through  
the entire dae file and changes some of the tags because I noticed  
that LW9.6 seems to create them with the names/labels/attributes in a  
different order than Papervision seems to be looking for
- Using an XML editor I go through and delete all the animation  
channels that are empty as they also seem to confuse Papervision. I am  
hoping to create a GREP pattern for this too eventually but I haven't  
had time lately.

I hope this helps. It's still not a one-step solution but it's better  
than going line-by-line.

Peter, no I was unaware of it, but it is what I was talking about, so I do appreciate it;

however, I have already started the process of writing my own LW_dae_fixer which will take in a LW.dae ( actually LW_dae.xml ) and produce a pv3d-ready_dae.xml;


thanks,
Shannon

Ianim8, thanks for responding;

if I am successful at producing something that works I will post it here;

I have built a small flash app that cleans up my LW Modeler 9.6 .dae;

it addresses:

<library_geometries><geometry ...> ... <polylist ... COUNT='0'>  
       
<library_visual_scenes><visual_scene ... > ... <instance_material ... REDUNDANT >
       
<library_materials><material ... id="..._#" name="..._#" REDUNDANT>
           
<library_images><image ... id="..._#" name="..._#" REDUNDANT>

<library_images><image ...><init_from> ABSOLUTE PATH
       
<library_effects><effect id="..._4-fx" REDUNDANT>
       
<library_geometries><geometry ... > ... <source id="IDENTICAL ID's" name="uvmap">

<geometry id="Mesh_Object_2_lib" name="Mesh_Object_2"> REPLACE LW names ( 'Mesh_Object_#' ) with your layer names


for me it has removed 1000 lines of unnecessary(?) stuff from my LW.dae, from 1846 lines to 815

for anyone using LW Modeler 9.6 who would like to look at it, please let me know and I will upload it;
