Tutorial – How to use fSpy with Blender

Показать описание

This tutorial demonstrates how to use fSpy to define the vanishing points of any image*, and thus, depending on your accuracy, recreate the characteristics of the perspective of the given image. This is useful in many visualization scenarios, but in this tutorial, fSpy will be used to lay a practical foundation for the modelling of a mesh from a photo reference.

Disclaimer:
*The software fSpy is only designed to function with pinhole camera photographs and renders – it will not work with axonometric drawings, orthogonal renders, fisheye lenses, and other situations where perspective lines do not ultimately meet up colinearly. If your vanishing point axes are not assigned as in the tutorial video (1 as X, 2 as Y), you will have to do so, unless your particular situation requires another combination. The timelapse in the end proved more than uncomfortably jittery, and while it is not proven to induce seizures, caution is advised (perhaps it is less irritative at half playback speed). In at least one instance, "colinear" is stated, when "parallel" would be correct. There might be more inaccuracies in this tutorial video – if you identify any significant one, please tell us in the comments.

Thank you! An fSpy tutorial that actually explains how the reference distance works.

Don't know why this video doesn't have 55K thumbs up... very nice!

Thank you so much for actually showing how to install the addon (unlike the other tutorials)! This is really handy when a little photogrammetry has failed. Now all I have to do is align them...

Very nice tutorial. And I love Erik Satie BTW!

Really, really: Excellent tutorial. Thank you very much.

Heheheh Kiruna. Blir alltid knas när jag ska använda fSpy. Nice tut! Nu kanske jag äntligen kan få det att funka.

Thanks, this is an excellent tutorial. I'm only starting to learn Blender, and was wondering whether fSpy can also be used to dynamically apply or project the textures from the objects in the photo onto the equivalent objects in the model? For example, can the the brickwork texture from the photo be dynamically projected on to the 3d model of the building?

Thank you Filippo Brunelleschi! Btw, great tutorial!

Really informative and helpful!!! Thank you!

My version of Blender is not installing the plugin.
Is this problem caused by the version of the software that I'm using? (3.1)

Thanks for the tutorial, by the way my reference has 1 vanishing point, I don't know what to pay attention to and is there anything that is much different from the two vanishing point setting

Great video, thanx, one question about the final position of the gizmo, somehow intuitively want to have it at the bottom base of the house .
