CloudCompare forum

You can define multiple in a single file if you add a blank line between each series of vertices.

So playing with this idea (but in a very simple way ;), I realized that there's no way we can determine the corner unless the camera looks straight (and in orthographic mode). Otherwise, the coordinate of the corner depends on the depth (along the camera direction, and along something more complicat...

So mind that the yellow cross is not the coordinate system or the screen center, it's simply the 'custom light position' (F7 to toggle it). Are all the colors and materials are at their default? Can you try to reset them? (in the Display properties). The background is not supposed to be pure black e...

And can you show what the rest of the screen look like? Ideally a screen capture of the whole CloudCompare application would do.

Don't you see the scale in the second screenshot? Or are you referring to something else?

<t>Ah, that's not easy! We should probably display these pieces of information somewhere at export time (even if I'm not sure for the 'orientation' part either).<br/> <br/> Meanwhile, if you were using the default camera orientation (axis aligned), you could use the camera eye/center in the Camera s...

That's probably the projection mode that you need to change (from Perspective to Orthographic - F3 shortcut)

Ah non en effet c'est assez différent. Je ne vois pas de moyen simple et robuste d'extraire ça dans CC.

Not directly...

Well, the normals of the 3 planes are simply the 3 first columns of your 4x4 transformation matrix that would transform any point in your local coordinate system into the global one. But for the origin, I don't think there's a clean way to extract it in CC.

Ah, pour ce genre de classification, qui ne se base pas sur des caractéristiques morphologiques, la seule solution que je vois serai d'utiliser le plugin 3D-masc en utilisant une information de normal (pour regrouper les points selon leur direction). Ou alors l'extraction de plans avec le plugin Ran...
