OO_WavefrontExport.vbs (OBJ export Frame By Frame)

[katsu]

Hi,

# I'm sorry for my poor English.

I have installed XSI on WinNT4.0, and am trying OO_WavefrontExport.vbs
to export the information of geometory and texture coordinate to .obj frame by frame.
But I have some questions.

My one question is in ' function parseUVs ' codes;

(snip)
'Find the "sample" clusters
set oClusters = oGeom.Clusters.Filter("sample")
(snip)

---

Why finding clusters is needed?
In addition, what is "sample" clusters?
Why "sample" clusters are found by Filter?

In my case, oClusters is empty ("") everytime, so I can't get uv information.
(texture mapping has been done, of course.)
I can get verticies, normal and faces informations in exported file, though.

I would be happy if someone help me.

BTW, I'm wondering if XSI can export to .obj as well as .xsi and .iges
without the help of scripts (i.e. standard spec)...

In XSI, when you texturemap an object, it creates a UV property under the object. This UV property is in a Cluster of type "Sample". This is why I have to retreive the UV information by finding the clusters.

'Find the "sample" clusters
set oClusters = oGeom.Clusters.Filter("sample")

.Filter() will return only the item that are of the requested type. so by running .filter("sample") I will get only the clusters of type sample which contains the UV information.

I'm very very glad that the author told me about the script.
Thank you very much for your kindness.

Now, thanks to you, I can get the UV information.
To tell you the truth, my texturemapping seemed to be done....
I'm sorry for my luck from the bottom of my heart.

But, I'm new to XSI, so your informations help me.
Again, thank you very much.
I would be happy if you give me some advices about writting XSI scripts.
