QuarkCore

An OpenGL rendering library built to make lighting easy for the Quark Engine — and ~1.5x faster than Raylib.

---

Quick Start

Requirements

• C++17 or later
• OpenGL 3.3+
• CMake 3.16+

Installation

git clone https://github.com/Quark-Engine/QuarkCore.git
cd QuarkCore
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

Then link against QuarkCore in your CMakeLists.txt:

target_link_libraries(your_target PRIVATE QuarkCore)

---

Usage

#include "QuarkCore/QuarkCore.hpp"

int main() {
    qc::InitWindow(1280, 720, "Hello World");
    qc::SetTargetFPS(60);

    while (!qc::WindowShouldClose()) {
        qc::BeginDrawing();
        qc::ClearBackground(qc::Color{20, 24, 32, 255});

        qc::DrawText("Hello, World!", 360, 340, 32, qc::WHITE);

        qc::EndDrawing();
    }

    qc::CloseWindow();
    return 0;
}

Built-in Shader Constants

QuarkCore exposes its default vertex shader source so you can pair it with any custom fragment shader:

qc::LoadShaderFromMemory(qc::kVertexShaderSource, myFragmentShader);

Examples

The examples/ directory contains demos for:

• sandbox.cpp — window setup, 2D/3D cameras, render textures, text rendering
• shaders.cpp — chromatic aberration, pixelation, vignette, scanlines with live parameter tuning
