PhongMaterial

Represents a material for shiny surfaces with specular highlights.

This material implements the Blinn-Phong model for calculating reflectance. It is suitable for rendering glossy or metallic surfaces that require highlights and simulate light interaction.

auto material = vglx::PhongMaterial::Create(0x049EF4);
material->specular = {0.3f, 0.3, 0.3f}
material->shininess = 32.0f;
material->albedo_map = texture;

auto mesh = vglx::Mesh::Create(geometry, material);
scene->Add(mesh);

Derives from Material and inherits all public properties and methods.

Construction

Constructors

PhongMaterial()

vglx::PhongMaterial::PhongMaterial(const Color &color)

Parameter	Description
color	Color of the material.

Constructs a PhongMaterial object.

Factories preferred

PhongMaterial::Create() auto

static auto vglx::PhongMaterial::Create(const Color &color=0xFFFFFF)

Parameter	Description
color	Color of the material.

Creates a shared pointer to a PhongMaterial object.

Properties

albedo_map std::shared_ptr<Texture2D>

std::shared_ptr<Texture2D> albedo_map { nullptr }

Albedo (base color) map, optionally containing an alpha channel.

alpha_map std::shared_ptr<Texture2D>

std::shared_ptr<Texture2D> alpha_map { nullptr }

Alpha map that controls the opacity across the surface.

color Color

Color color { 0xFFFFFF }

Color of the material.

normal_map std::shared_ptr<Texture2D>

std::shared_ptr<Texture2D> normal_map { nullptr }

Normal map that perturbs surface normals for detailed shading.

shininess float

float shininess { 32.0f }

How shiny the specular highlight is; a higher value gives a sharper highlight.

specular Color

Color specular { 0x111111 }

Specular color of the material.

Functions
