Need UV Atlas help

Need UV Atlas help

• Maparisi

  Thanks, Ross.  I'll see what kind of trouble I can get into with that...

  _anybody_ who has messed with this please let me know so I don't feel sooooooooo all alone. WAAAAAAAAAH!!!!!

  
  I can't help as such right now... but, time permitting this week, I'm planning on having a look at getting it to work.
  
  If I have enough time to get something useful working I'll probably post it in my developer journal if you're interested

  Thanks Ross, but I've read all the dox and also scoured the web for samples.  I have yet to find any working code.
  
  Has anybody successfully used this class

  The UV Atlas stuff is pretty new, I don't know if anyone has seriously tried using it in managed code.  It's still seems to in state of flux and it does have some issues, but there are people are using it in C++.  You might try playing around with the uvatlas command line tool in the SDK and see if that gives you any insight on how things are supposed to work.  If you have any specific problems with using UV Atlas in managed code, if you've tried using it and it's not working the way you expect it to, you should post them here and maybe someone can help you out.

  What exactly are you asking for   Do you want a texture map output with the mesh drawn on a texture   Are you asking for it to combine existing textures on the object into one texture

  "Do you want a texture map output with the mesh drawn on a texture "
  
  Yes, precisely.  I would like to be able to output a texture template that I could draw on in Photoshop.

  okay, i've been messing with the uvatlas C++ command-line tool.
  
  i understand that it generates a new mesh with optimal UV mappings, but is it possible to have it output a texture map that corresponds to those settings
  
  the closest i've been able to come is to have the tool use the /t option and output an .x file that has unwrapped the mesh onto a single plane.

  Try reading the C++ documentation.  There's a section there called "Using UVAtlas" that doesn't seem to be in the Managed documentation.  It seems to have a good explaination of what's going on with Integrated Metric Tensors.

  Okay, here I am responding to my own post, but this is a bit more clarification...

  Anybody have a clue   Dave Tom ... Bueller =)

  Hmm... no, it doesn't look like the uvatlas command line tool can do that.  You can however generate an appropriate texture in your own code by using the TextureGutterHelper.ResampleTexture method.
