Core::Display::Color

Introduction

The Color class provides a structured way to manage and manipulate color values, especially when integrating with GLM's vector systems.

Usage

Initialization

The Color structure comes with four floating-point components for representing RGBA values:

struct Color {
    float red = 0.0f;
    float green = 0.0f;
    float blue = 0.0f;
    float alpha = 1.0f;
};

By default, the color is initialized as transparent black.

Working with Vectors

Color can directly interact with glm::vec3 and glm::vec4, allowing for streamlined assignments:

For glm::vec3:

• x corresponds to red

• y corresponds to green

• z corresponds to blue

For glm::vec4:

• x corresponds to red

• y corresponds to green

• z corresponds to blue

• w corresponds to alpha

Operators

Color Operators

Assign color values directly from an initializer list:

Color color;
color = {255, 0, 0}; // Set to Red

Vec3 Operators

Directly assign values from a glm::vec3:

glm::vec3 vec(1.0f, 0.0f, 0.0f);
Color color;
color = vec; // Set color to Red using a glm::vec3

Vec4 Operators

Similarly, you can assign values from a glm::vec4:

glm::vec4 vec(1.0f, 0.0f, 0.0f, 1.0f);
Color color;
color = vec; // Set color to opaque Red using a glm::vec4
