What is the meaning of vertices/ triangles in 3D Scan

SJung11 — Tue, 13 Dec 2016 07:08:56 GMT

Hello, i;m working with realsense (sr300/ r200)

I want to know what is the meaning of 'Vertices' and 'Triangles'

please.... i'm waiting for your answer!

Hello suho,

Thanks for reaching out!

I'd like to quote a small paragraph from the first link you shared:

"...Vertices and Triangles: In order to limit the output mesh (geometric) complexity, set either the maxVertices or maxTriangles according to your usage requirements. If both are set, the mesh complexity is reduced to the point where both are satisfied..."

What this means is that depending on the amount of vertices and triangles used in a 3D scanning the image recovered will be more accurate.

I might not be explaining it clear enough, so, I suggest you to read the following document to learn more about triangle meshes:

I hope this helps.
