Struct MeshPatch 

pub struct MeshPatch {
    pub control_points: [[Point; 4]; 4],
    pub corner_colors: [Rgba; 4],
}

One colour patch of a Type 6 (Coons) / Type 7 (tensor-product) patch mesh (§8.7.4.5.7–8). The patch geometry is a bicubic surface; Type 6 patches are stored as the equivalent tensor-product patch (the four internal control points derived from the boundary curves per the §8.7.4.5.8 conversion equations), so both types share this 4×4 control-point representation.

Fields

control_points: [[Point; 4]; 4]

The 16 tensor-product control points p[col][row] (§8.7.4.5.8 Figure 32) in the shading’s target coordinate space. For a Type 6 Coons patch the four internal points (p[1][1], p[1][2], p[2][1], p[2][2]) are computed from the boundary curves.

corner_colors: [Rgba; 4]

The four corner colours, in the §8.7.4.5.7 corner order (c1=p00, c2=p03, c3=p33, c4=p30). The patch interior colour is the bilinear interpolation of these four.

Trait Implementations

impl Clone for MeshPatch

fn clone(&self) -> MeshPatch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MeshPatch

impl Debug for MeshPatch

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

Formats the value using the given formatter.

impl PartialEq for MeshPatch

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
