Trait GaussianShConfig 

pub trait GaussianShConfig {
    type Field: Pod + Zeroable;

    const FEATURE: &'static str;

    // Required methods
    fn from_sh(sh: &[Vec3; 15]) -> Self::Field;
    fn to_sh(field: &Self::Field) -> [Vec3; 15];
}

The spherical harmonics configuration of Gaussian.

Currently, there are four configurations:

• Single precision GaussianShSingleConfig
  • Format: 15 * Vec3
• Half precision GaussianShHalfConfig
  • Format: (15 * 3 + 1) * f16
• 8 bit normalized GaussianShNorm8Config
  • Format: (15 * 3 + 3) * i8
• None GaussianShNoneConfig
  • Cannot be converted back to SH

Required Associated Constants

const FEATURE: &'static str

The feature name of the configuration.

Must match the wesl::Feature name in the shader.

Required Associated Types

type Field: Pod + Zeroable

The GaussianPod field type.

Required Methods

fn from_sh(sh: &[Vec3; 15]) -> Self::Field

Create from Gaussian::sh.

fn to_sh(field: &Self::Field) -> [Vec3; 15]

Convert the field to Gaussian::sh.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
