mapping
7 messages in this thread
Fist : sorry about my "inglish", i'm a french man.
My problem is quite simple : I want to create a symbolic vue of a town. For
this, I create a mesh objet which represent the landscape in 3d. I want to use
an aerien photographie of the town as texture map. The problem is that faces
are not in the same direction, so my splendid photographie is difformed (
"difformed ?") .
Thanks for answers.
I've done this kind of thing plenty of times (photography on top of a 3d mesh)
and can probably help you.
Can you provide more detail on what you mean by "deformed". Have you tried
unifying your face normals, then doing an Auto-Smooth?
<< more detail on what you mean by "deformed">>
Thank's for your answer.
What i mean is for example a town with a great hill ( or a moutain ).
I suppose if the hill had a very steep cliff, then the mapping would tend to
distort, but if you are using air photography, I have found that just using
planar mapping straight down on the model tends to work ok. Then again, I
haven't tried to do a model of El Capitan, either.
The only thong is that my map is very "precis". I mean about 2400*1800 because
i want to look at it very closely. So if I "map" on a flat mesh,it will be
good, but as soon as i deform my "terrain", distorsion isn't acceptable.
Perharps i can transform my flat mesh to my final mesh ?
Well, I don't know what else to suggest on what you have told me without seeing
a rendering of you final image. I have used satellite images of a higher
resolution than you have for yours with good results. The only thing you have
to be aware of is that the higher the resolution of the map, the more
sub-sampling the program has to do to get it down to typical image resolution,
and it can look fuzzy because of that. Yours sounds more like you have a sheer
cliff that is stretching the map strangely, though.
Thanks for all your answers. See you soon.
