pub vertices: [Vec3; 3],
}
Expand description
A 3D triangle primitive.
Fields§
§vertices: [Vec3; 3]
The vertices of the triangle.
Implementations§
§impl Triangle3d
impl Triangle3d
pub fn new(a: Vec3, b: Vec3, c: Vec3) -> Triangle3d
pub fn new(a: Vec3, b: Vec3, c: Vec3) -> Triangle3d
Create a new Triangle3d
from points a
, b
, and c
.
pub fn normal(&self) -> Result<Dir3, InvalidDirectionError>
pub fn normal(&self) -> Result<Dir3, InvalidDirectionError>
Get the normal of the triangle in the direction of the right-hand rule, assuming the vertices are ordered in a counter-clockwise direction.
The normal is computed as the cross product of the vectors ab
and ac
.
§Errors
Returns Err(InvalidDirectionError)
if the length
of the given vector is zero (or very close to zero), infinite, or NaN
.
pub fn is_degenerate(&self) -> bool
pub fn is_degenerate(&self) -> bool
Checks if the triangle is degenerate, meaning it has zero area.
A triangle is degenerate if the cross product of the vectors ab
and ac
has a length less than 10e-7
.
This indicates that the three vertices are collinear or nearly collinear.
pub fn reverse(&mut self)
pub fn reverse(&mut self)
Reverse the triangle by swapping the first and last vertices.
pub fn centroid(&self) -> Vec3
pub fn centroid(&self) -> Vec3
Get the centroid of the triangle.
This function finds the geometric center of the triangle by averaging the vertices:
centroid = (a + b + c) / 3
.
pub fn largest_side(&self) -> (Vec3, Vec3)
pub fn largest_side(&self) -> (Vec3, Vec3)
Get the largest side of the triangle.
Returns the two points that form the largest side of the triangle.
pub fn circumcenter(&self) -> Vec3
pub fn circumcenter(&self) -> Vec3
Get the circumcenter of the triangle.
Trait Implementations§
§impl Bounded3d for Triangle3d
impl Bounded3d for Triangle3d
§fn aabb_3d(&self, translation: Vec3, rotation: Quat) -> Aabb3d
fn aabb_3d(&self, translation: Vec3, rotation: Quat) -> Aabb3d
Get the bounding box of the triangle.
§fn bounding_sphere(&self, translation: Vec3, rotation: Quat) -> BoundingSphere
fn bounding_sphere(&self, translation: Vec3, rotation: Quat) -> BoundingSphere
Get the bounding sphere of the triangle.
The Triangle3d
implements the minimal bounding sphere calculation. For acute triangles, the circumcenter is used as
the center of the sphere. For the others, the bounding sphere is the minimal sphere
that contains the largest side of the triangle.
