[Verse-dev] Creating some basic geometry

Hi,
I see another mistake in your code ...

nodeId = 0 is usualy ID of avatar node (verse server creates this node  
for your verse app).
If you will use this id for geometry node, then nothing will works.  
You have to call this function

verse_send_node_create(-1, V_NT_GEOMETRY, (VNodeOwner)avatar);

Then you have to wait for callback function and id of geometry node  
created by you ... use this ID
in all following functions:
