ludus::content::scene_source::SourceMaterial¶

Struct

A named material. Emission makes every polygon that uses it a light.

#include <ludus/content/scene_source/scene_source.h>

struct ludus::content::scene_source::SourceMaterial final

Fields¶

foundation::String ludus::content::scene_source::SourceMaterial::Name

Unique, nonempty name that objects refer to.

SourceMaterialModel ludus::content::scene_source::SourceMaterial::Model = SourceMaterialModel::Diffuse

Reflection model; roughness also applies to project BRDF programs.

foundation::math::Vector3d ludus::content::scene_source::SourceMaterial::BaseColor {0.5, 0.5, 0.5}

Linear Rec. 709 reflectance, each channel in [0, 1].

float64 ludus::content::scene_source::SourceMaterial::Metallic = 0.0

Metallic fraction in [0, 1]; zero for Diffuse.

Related types: float64

float64 ludus::content::scene_source::SourceMaterial::Roughness = 1.0

Perceptual roughness in [0, 1]; one for Diffuse.

Related types: float64

float64 ludus::content::scene_source::SourceMaterial::MixWeight = 0.0

Conductor weight in [0, 1]. The Lambertian lobe uses the complementary weight and BaseColor.

Related types: float64

SourceRoughConductor ludus::content::scene_source::SourceMaterial::Conductor

Conductor inputs for Mix materials.

SourceProjectBrdf ludus::content::scene_source::SourceMaterial::Brdf

Authored program for ProjectBrdf materials.

foundation::math::Vector3d ludus::content::scene_source::SourceMaterial::EmittedRadiance {}

Constant emitted linear Rec. 709 radiance in W/(sr m^2) per channel, finite and nonnegative; all zero for a material that does not emit.

bool ludus::content::scene_source::SourceMaterial::IsEmissionTwoSided = false

True when polygons emit from both faces; false emits from the front face only.
