Struct nannou_core::geom::tri::Tri [−][src]
Expand description
A triangle as three vertices.
Tuple Fields
0: [V; 3]
Implementations
Create a Tri by indexing into the given buffer.
Panics if any of the given indices are out of range of the given vertices
slice.
Create a Tri from the next three vertices yielded by the given vertices
iterator.
Returns None if there were not at least 3 vertices in the given iterator.
Produce an iterator yielding each of the vertices of the triangle.
Produce the centroid of the triangle aka the “mean”/“average” of all the points.
Maps the underlying vertices to a new type and returns the resulting Tri
.
Returns true
if the given 2D vertex is contained within the 2D Tri
.
Example
let a = [-0.5, 0.0];
let b = [0.0, 1.0];
let c = [0.5, -0.75];
let tri = Tri([a, b, c]);
assert!(tri.contains(&[0.0, 0.0]));
assert!(!tri.contains(&[3.0, 3.0]));
The bounding Rect
of the triangle.
The bounding Rect
of the triangle.

Convert into T. The resulting color might be invalid in its color space Read more
Convert into T, returning ok if the color is inside of its defined range,
otherwise an OutOfBounds
