Struct Patch 

pub struct Patch {
    pub control_points: Vec<Vertex>,
    pub factors: Factors,
    pub vertices: Vec<Vertex>,
    pub locations: Vec<[f32; 2]>,
    pub topology: TessTopology,
    pub indices: Vec<u32>,
}

What the tessellator made of a patch, with the programs’ results.

Fields

control_points: Vec<Vertex>

The hull program’s output control points: one register per output varying (TessellationShader::control_outputs).

factors: Factors

The tessellation factors the hull program wrote.

vertices: Vec<Vertex>

The domain program’s result for each point the tessellator made: one register per output varying of the domain program (TessellationShader::outputs).

locations: Vec<[f32; 2]>

The domain locations of the points (u, v; a triangle’s third coordinate is 1 - u - v).

topology: TessTopology

What indices make: points, lines or triangles (clockwise or counter-clockwise in the domain, as the hull program says).

indices: Vec<u32>

Point numbers, one per point of a point list, two per line, three per triangle.

Trait Implementations

impl Debug for Patch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Patch

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
