Thanks for the information. I already have a few from RPC. What I need now is some doctors and nurses fully dressed for an operation. We have already made some of this models but they don't look good.

 

I am attaching a real live photo of what I need.

 

Thanks

That is very nice. You are very good with Photoshop and that Alpha channel. Question.... I am trying to place these people inside the the 3D Max model instead of placing them as a Photoshop post processing. How would you do that....?

 

Thanks

Trevor,

Nope no Photoshop Plugin. It's closer to 'rotoscoping', the technique used. Some Path work and painting on a mask. The RGB colors in the image made using channels to extract or even get a good start on a decent mask impossible or at least I could not see the 'Math' to get it done. Add-Subtract, divide.....channels.

 

'Clean' is actually an eyeball and paint out artifacts that show against different colored backgrounds method...though still it took about 15 minutes.

I think the hardest part of using just any image is matching the 3D scene's camera to the camera of an image like this. Though looking at the image, the camera hieght is that of a man apx 6' tall about 6-8' away (given the size of an opperating room) 40-55 degree field of view, incline (target about 20' away-3.5' off the ground). That would match, best guess, a scene camera to the prepared image.

 

You can take that full image use a plane (Billboard) that matches it's aspect ratio and apply the image as a texture, then use the alpha for an opacity mask to remove everything but the surgical people. That's the easiest way.

 

The over the top way and LOL not so easy is modeling from a camera projection (camera mapping or Image modeling) to match the subject/s. Bake the texture to the matching geometry....then in photoshop use the existing pixel information to fill in where the camera doesn't 'project'....3D version that does not need to be 'camera' matched.

 

To be quite honest, if this is something you'd regularly need for your work it might be worth 'rolling' your own or having someone roll them for you. You got the camera equipment, access to medical personel & facilities.... something to think about. If it's good enough LOL Retial the goods and make some pocket change.
