I was asked to model pic rel, and for some reason it has me stumped. I think part of the reason is the angle of the image which seems to make it a bit awkward. How would you go about modeling from a reference like that?

Start out by finding some achor.points in the image like figuring out what is at equi-distance from one another in the depth of the image and drop in some geometry that reflect this in your scene and start establishing the relationship between elements in your image.

Tell the voices in your head that Paris has been 3D scanned to death over the years.

... make a snapshot of the map of the part of paris you need, create simple objects that represent the buildings, place camera, tune it a little bit until its fits, etc ... or you can use some google maps addons to get 3d models of that area, but needs some installations and other stuff.

Download the car and the Eifel tower, after that you make all the buildings modular.

1.Take a random video of youtube from Rue de Camoens.
2. Take snapshots every second or every atime the camera angle changes.
3.Use those inputs in a photogrammetry software.
The more videos you find the more you can add to the point cloud.
You can model from there.

It's garbage.

... i guess you dont even need random ytvids of that location! just use the 360° view in google streetview for the photogrammetry software!
when you dont mind, could you try it for us to see if that works?

...this persepective could be usefull too!

Anon, you don’t know how 3D scanning works do you… Why do i have a feeling you’re using incompetent software to render LIDAR or photogrammetry technology.

Can you show us proper 3d scanning workflow?

Hope you like educated CAD information

And then what do you do with the point could? What software do you use? What kind of results do you get.
The scanning process is just beginning of the workflow but where's the rest of the workflow?
And what do you do when you realize your point cloud is pure garbage and that you're going to need months of manual labor to fix it?
What's the correct workflow to avoid such scenarios?

Find other references to draw from. Use them to fill in the gaps of your understanding. Also take that shit into photoshop and plan out what you need to create. Sticking to just one reference is retarded.

Nope street view 360's don't work very well unless you do some heavy processing.Photogrammetry software uses sub-pixel calculations wich usually die with the distortion and tile compression that 360 panos from google usually do.
I could manage to make it but I would end up manually setting up reference point between 360 panos in order to guide the software process.

>You are not using the latest biggest lidar in situ for a 4chan comment so you are definitely not an expert.
Not even worth it proving a point with a quick example with this caliber of comments.

My point exactly.

..ok!
