Photomatching problem...

Hieru

Alternatively you could adjust the perspective in the photo (using PS or similar) unil you get some good red and green axis lines.

hi,

thanks for tips, but i have no other chance to make another shot, have to use this one.

t thought, it won´t be a problem to make an exception in this case.

i know the lines have to be set in difference angle from usual, but where to place them right?

there´are some additional lines with red and green which i didn´t see in videos, i´m sure they´re important.

any hotkey to draw rectangular from middle point like circle?

How about a 4 sided polygon? (it will always be the special "square" case of a rectangle though)

I don't think anything like perfect is achievable with Match Photo. It is what it is. How does your model look in the photo?

tibet

hi,

finally, i´ve done somehow , but it´s not perfect as i like it to be.

What happens when you click on the black right=pointing arrow to the right of "In Model" and click on Purge Unused?

By the way, when you open a new file, how many materials show up in the In Model library? If you have any, purge them. If they won't go away, purge unused components first.

tibet

hi Dave,

thank you very much, all my unused model leftovers´s been trown "purched" away

i´m glad to have you around !

cheers!

tibet

hi Gaieus,

thanks for valuable tips, very nice indeed.

i can´t believe it, i missed 4-sided polygon, you hit the jackpot

Make Unique Texture ++ is truly amazing plugin, i´m sure it comes handy.

by the way, don´t you remember plugin, which helps you to get rid off textures and materials ,

which aren´t used in the model /see below

hi pbacot,

well, the photo doesn´t mach exactly, because i got some fixed distances i have to use it for basic construction.

best of luck!

tibet

hi guys,
i´ve encountered the same problem as before ( pic on the right side)
is this deformated effect created by an agle of shooting or camera intself, so that i can´t properly put green and red lines?
thanks

hi,
well, usually i get just 1 shot from someone to make model into it.
i dont have another one, and this is uncropped, only reduced copy.
the original has 6MB.
any idea which side is wrong and how to fix eg.in photoshop?
thanks

pbacot

are you sure these photos are not cropped? I was curious and they looked to me to be different aspect ratios.

Wait, that looks a lot like two photos stuck side by side. Different light etc. Yes it works better if you cut out just the right photo. You should only Match Photo with one shot unchanged as it comes from your camera, without cropping, borders, or distortion.

pbacot

See my edit above.

tibet

hi,
thanks , but the another photo has nothing to do with it.
i just uploaded them together, so i can use it as texture in SU for another model.
unfortunately, neither of them are cropped.
cheers

Dave R

Something is different with that photo. I can't put my finger on it but it isn't something you're doing wrong with Match Photo. Are you in need of the materials off that thing? If not, I think it would be easier to draw it by hand without the photo.

tibet

hi dave,
there´s uploaded skp file with photo.
well, often i use original file, beause they wanted me to do like that
i´ve redraw it, but i´m still waiting for tip how to do successful photomaching with any kind of shot i get.
cheers!

Dave R

Just for the heck of it, trim the photo to get rid of the left half. Does that change anything for setting up Photo Match?

pbacot

I believe Match Photo needs the shape (aspect ratio) of the photo to be correct, because it is often shown that an altered photo will not work. I took off the left side and the right side seemed to work more normally. In my experience you should be able to make the blue line vertical and place it where you like.

In an image editor you select the right side as best you can, with a rectangle selection, and "crop" it. Re-save image. Then begin again in SU with a new Match Photo.

You need to get them to let you take your own photo. Match Photo obviously uses calculations about photographs to simulate its perspective view. The only information SU gets, besides you outlining the perspective lines, is the shape and size of the photograph.

Dave R

George, this one turned out to line up nicely, didn't it? Very good. I think the problem with your original image in this thread is that you are missing a needed vanishing point. Well, it is there but it is so far away that the lines appear parallel. With those lines being parallel, it is impossible to determine the field of view of the lens in SketchUp. That's a large part of what you are doing with Photomatch.

tibet

hi,

thanks for your valuable advices, but i´ve been wondering why i didn´t succeed with the pic at the start of this thread
