Enum MaterialType 

pub enum MaterialType {
    Unlit(UnlitMaterial),
    Phong(PhongMaterial),
    Physical(PhysicalMaterial),
    Custom(Box<dyn RenderableMaterialTrait>),
}

Material data enum with hybrid dispatch strategy.

Uses “static dispatch + dynamic escape hatch” approach:

• Built-in materials (Unlit/Phong/Physical) use static dispatch for performance
• Custom variant allows user-defined materials via dynamic dispatch

Built-in Materials

• UnlitMaterial: Unlit, flat-shaded material
• PhongMaterial: Classic Blinn-Phong shading
• PhysicalMaterial: PBR material with metallic-roughness workflow, clearcoat, transmission, etc.

Variants

Unlit(UnlitMaterial)

Unlit material (no lighting calculations)

Phong(PhongMaterial)

Classic Blinn-Phong shading model

Physical(PhysicalMaterial)

Advanced PBR material with additional features

Custom(Box<dyn RenderableMaterialTrait>)

User-defined custom material

Implementations

impl MaterialType

pub fn as_custom<T>(&self) -> Option<&T>

where T: MaterialTrait + 'static,

Tries to downcast to a concrete type (for Custom materials)

pub fn as_custom_mut<T>(&mut self) -> Option<&mut T>

where T: MaterialTrait + 'static,

Tries to downcast to a mutable reference of concrete type (for Custom materials)
