I am a bit confused about what exactly is being pictured and referred to in the boundary. Is the right edge of the boundary mesh actually the bottom edge of the surface?

Midoriya

How do we check if an edge is a boundary mathematically? Can we say that an edge is a boundary if it is adjacent to only one face?

ant123

I'm still not sure what we mean by boundary vertices should look like pacman? Does this mean they should have a "fan" of polygons coming out of them on one side, while the other side is empty?

daria

What does it mean by locally and globally?

richardnnn

What does it mean for boundary to "look like a half disk locally"?

TejasFX

I’m really confused as to how to visualize this… could an animation of somebody zooming into a boundary like this be provided? (I feel like it would help my and other’s understanding of this concept.)

Dalyons

If our meshes are the empty shell and nothing inside, then if there is a boundary that allows us to look inside...what do we see? I.e., how does the inside of the pants look?

snaminen

What is a boundary vertex?

spidey

What is the difference between locally and globally, how does it look like a half disk vs. pacman in these two cases?

Starboy

Could the boundary look like a disk instead of a half disk locally?

ml2

What exactly was the boundary on the pants? I'm a little confused about the difference between a strip and a loop.

Marco

Why does the polygon mesh look like a pacman on the boundary?

kkzhang

Do boundaries exist on closed surfaces? In the example, the pants is assumed to have no thickness, but do boundaries only exist on surfaces that doesn’t have a notion of thickness?

Coyote

Do polygon meshes normally have boundaries? I generally thought that they would be closed loops to give the shape some sort of thickness.

siamese

What is boundary? I'm very confused

Concurrensee

will the boundary in the back of the texture same as the one in the front?

anj

Does globally refer to the entire edge of the pantleg? Is that why it forms a loop?
