Struct Triangle 

pub struct Triangle {
    pub a: DVec3,
    pub b: DVec3,
    pub c: DVec3,
}

One triangle, in metres.

Wound counter-clockwise seen from outside, which is what makes Mesh::volume positive. STL states a normal per facet as well, and it is ignored: exporters disagree about it often enough that the winding is the more reliable of the two, and carrying a normal that might contradict the vertices would mean choosing between them at every use.

Fields

a: DVec3

First vertex.

b: DVec3

Second vertex.

c: DVec3

Third vertex.

Implementations

impl Triangle

pub fn normal_area(&self) -> DVec3

Twice the area as a vector along the normal — the cross product of two edges.

pub fn area(&self) -> Area

The triangle’s area.
