Material

struct Material

OBJ-style material definition with PBR properties.

Direct representation of .obj style material with ambient, diffuse, specular components and modern PBR extensions for metallic workflow.

Public Members

std::string name

Name identifier for the material.

Vec3 Ka

Ambient color component (RGB).

Vec3 Kd

Diffuse color component (RGB).

Vec3 Ks

Specular color component (RGB).

Vec3 emissive

Emissive color component (RGB).

float Ns = 50.0f
