Photo match

Hi guys

could somebody explain to me the way the photomatch works ?

I have tried it using the manual that SU offers - but it results in me having chaos with lines ... and nothing usefull ...

So if somebody has some screenshots of HOW to position the lines ... that would be super

thanks a lot guys

Great video, but there is a crucial piece of information missing. You cannot grab any photo from the internet and expect Photo Match to work properly. It will not work on a photo that has been cropped and you have no clue whether the photo that you have grabbed from the web has been cropped. You must work with original photos with the viewer standing in the the center of the photo horizontally.

Next, photo match works best when there is a corner of the structure toward the viewer at a 45 degree angle. Other angles may work but 45 degrees is best. For an interior, you would want the back cornter to be at a 45 degree angle.

Aidan also very quickly mentioned the grid style.Make sure that you are using a grid style that matches your photo. If you are doing an aerial view, for instnace, you want a grid style that is the top down one and not the defualt architectural one. Just make sure that the photo isn't cropped or it won't work.

What if the cropped area is proportional to the original image and placed at the centre?

I imagine that should work. Can't think of any reason why not.

Note: no need to crop & stretch photos outside of SketchUp. You an use the tool we used before there was Photo Match: Texture Tweaker to stretch and pull the perspective right out of a photo. In fact you can use Texture tweaker together with Photo match to correct some distortions after your have photo matched.
It is a very simple Photo Match to use only one PHoto. If you look at the Photo match options after you have completed the first one, you will see that you have the opportunity to continue the Photo match with another photo from the other side of the buildin. You can continue on in this fashion.

In the SketchUp Book by Bonnie Roskes, she completes a very complex Photomatch of a hospital with many wings and with more than one Photo. It is pretty impressive.

videos 23, 27 and 36 at http://www.go-2-school.com explain several uses of photomatch.

http://sketchup.google.com/3dwarehouse/ check out the "modeling guide.pdf" in "model for google earth" at the right side of the page. page 16. that was very useful to me.

I am doing some work with photomatch for interiors right now and am finding that it is a very useful tool, but I have some caveats. Projected textures of floors and ceiling are coming out way darker than the original photo. It seems that is a programming draw back. Anyone else have comments on this. Also when projecting a hallway back it took off at a different angle even though I used the hall to set up one of my vanishing points.

Sue, I need to pop over to your company web page and see what you have in the way of furniture. I am going to need a ton of it in different styles. More than I want to model in a short time.

Am I correct that the texture tweaker is not avaialable within grouped objects?

what's "Texture Tweaker"?
