3d custom models(.obj ,.fbx...) in XML in form of pillars

Hello,
Has anyone managed to import 3d model into xml? Like in form of pillars for example. I believe proof of concept would be:
1. Decimate object in blender with triangulate option(
in forms of connected triangles, pic rel), low poly 3d. Export to .obj file.
2. Every triangle can be presented in xml as max. 2 pillars, since we have x1 and x2 required parameters for pillars.
3. Create a wrapper that from .obj file creates pillars for the whole model. It would process each triangle as max 2 pillars.
I don't want to re-invent the wheel if it exists...

No need to use pillars for that. <3dmodel> directive would be more appropriate. It's probably not yet documented at dsj4.pl
It looks like this:
Code: Select all
<hill ...>
<3dmodel id="vdf134-roof">
<batch id="roof" texture1="Textures\concrete5.png" material="Materials\material1.xml" fvf="322" order="0">
<vertex id="1" x="-3" y="0" z="-3" u1="-3" v1="-3" diffuse="0xff747681"/>
<vertex id="2" x="-3" y="0" z="3" u1="-3" v1="3" diffuse="0xff747681"/>
<vertex id="3" x="0" y="2.5" z="0" u1="0" v1="0" diffuse="0xff747681"/>
<vertex id="4" x="3" y="0" z="3" u1="3" v1="3" diffuse="0xff747681"/>
<vertex id="5" x="3" y="0" z="-3" u1="3" v1="-3" diffuse="0xff747681"/>
<vertex id="6" x="0" y="2.5" z="0" u1="0" v1="0" diffuse="0xff747681"/>
<vertex id="7" x="-3" y="0" z="3" u1="-3" v1="3" diffuse="0xff747681"/>
<vertex id="8" x="3" y="0" z="3" u1="3" v1="3" diffuse="0xff747681"/>
<vertex id="9" x="0" y="2.5" z="0" u1="0" v1="0" diffuse="0xff747681"/>
<vertex id="10" x="3" y="0" z="-3" u1="3" v1="-3" diffuse="0xff747681"/>
<vertex id="11" x="-3" y="0" z="-3" u1="-3" v1="-3" diffuse="0xff747681"/>
<vertex id="12" x="0" y="2.5" z="0" u1="0" v1="0" diffuse="0xff747681"/>
<face v1="1" v2="2" v3="3"/>
<face v1="4" v2="5" v3="6"/>
<face v1="7" v2="8" v3="9"/>
<face v1="10" v2="11" v3="12"/>
</batch>
</3dmodel>
<3dmodel-instance id="vdf134-roof" refx="inrun0" refy="inrun-top" x="3.525" y="2.85" z="1.175"/>
</hill>
Additionally you can define extra "seams" between vertices to smoothen the surface in normals calculation.
Code: Select all
<hill ...>
<3dmodel id="example">
<batch id="1" ... >
<vertex id="1" x="-3" y="0" z="-3" u1="-3" v1="-3" diffuse="0xff747681"/>
<vertex id="2" x="-3" y="0" z="3" u1="-3" v1="3" diffuse="0xff747681"/>
</batch>
<batch id="2" ... >
<vertex id="1" .../>
<vertex id="2" ..."/>
</batch>
<seam b1="1" v1="1" b2="2" v2="1"/>
<seam b1="1" v1="2" b2="2" v2="2"/>
</3dmodel>
</hill>

It's alive
Although, I just finished this by using python converter for triangulated obj model to pillars. I'll try with 3dmodel since it's very similar format to .obj file.
I see that in dsj24 hills this 3dmodel method wasn't used in any hill(it is present in zakopane hs140 xml, but it's commented out). I'm not sure if someone from gorisek will create documentation for this...

Wow, the things that will be possible with this... Don't worry sneze2r, documentation for this will be created sooner or later for sure!

I will try, not sure whether every attribute should be described or just tutorial how to import these models with small explanation.

Perfect
for now I think I've got everything. I'll play around
