Trait Interpolatable 

pub trait Interpolatable: Default + Clone {
    // Required method
    fn add_with_weight(&mut self, src: &Self, weight: f32);
}

Trait for data that can be interpolated by subdivision rules.

Implement this for any type you want to subdivide: positions, UVs, colors, normals, scalar weights, custom attributes.

Follows the OpenSubdiv Clear() / AddWithWeight() pattern. Using a local trait avoids orphan-rule problems that arise with Mul<f32> on foreign array types.

Example

use subdiv_kernels::Interpolatable;

#[derive(Default, Clone)]
struct Color { r: f32, g: f32, b: f32, a: f32 }

impl Interpolatable for Color {
    fn add_with_weight(&mut self, src: &Self, weight: f32) {
        self.r += src.r * weight;
        self.g += src.g * weight;
        self.b += src.b * weight;
        self.a += src.a * weight;
    }
}

Required Methods

fn add_with_weight(&mut self, src: &Self, weight: f32)

Accumulate src scaled by weight into self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
