advanced rendering for AutoCAD
Need help to match model with photo, please!
Hi all, I give up! I have this simple model to match with the photo. Red vertical lines correspond to red trees in the picture, cyan lines correspond to cyan trees. The picture has been taken from the top of the green vertical line (1,70 m high), and the camera is 28 mm of focal length (these settings are already set for the P_01 view). For those who better match the view, some more jobs are coming!! :)) Thanks to everybody who will try this hard job!

The view must be set at 2400x1200 pixel. The title of the post should be "need help..", of course, but it was really late in the night!

Hi, Miguel. I try, but it's very hard. Let me give you 2 advices. In first, don't trust the settings of the camera. The focal adjustement is an adaptation, for the numeric sensor, of the old argentic films settings.
In second advice, here is the way I do, to match a photo. I match approximately the point of view in the walkabout window. And after, in Pshop, with the "torsion" option of the "deformation" tool, I match the background picture to the rendered image.

Hi Marc, thanks for your reply. Yes, I know that focal lenght is just an addressing point to start from. In fact, I actually have to change it a little bit to match the photos. I think this is the hardest job I've ever been involved! And... yes, of course the final result needs some adjustments in PS. Yesterday, in one of my discouragement moments, I was looking for some tool over the internet, and I discover this one by Autodesk, and this other one for Lightwave. Of course, the core issue is to be able to use Lightwave!!

Thanks Roy. Not yet the hoped result. When could we have a good instrument for this kind of jobs?

Not from me.

Photo matching tools in the AutoCAD environment are not something I'm currently working on, nor are there any plans.

Ok. You're already doing so mucho for "our" beloved nXt, it would be really too much to ask you to develop pretty architectural tool for us. We all have to thank you for what you've done and still will do.
