OpenGL Graph and Text Rendering

This project demonstrates how to create a simple graph and render text using OpenGL and GLFW. It includes shaders for rendering both the graph and the text, and uses the stb_truetype library for text rendering.

Features

• Render a 2D graph
• Render text on the screen
• Basic input handling to close the application

Requirements

• OpenGL
• GLFW
• GLAD
• stb_truetype

Getting Started

Prerequisites

• Make sure you have the required libraries installed:
  • OpenGL
  • GLFW
  • GLAD
  • stb_truetype

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/yourproject.git

2. Navigate to the project directory: cd yourproject 3.Compile the project using your preferred C++ compiler. For example, using g++: g++ main.cpp -o graph_renderer -lglfw -ldl -lGL -lGLU 4.Running the Application Run the compiled executable: ./graph_renderer 5 .Code Overview Shaders vertexShaderSource: Vertex shader for rendering the graph. fragmentShaderSource: Fragment shader for rendering the graph. textVertexShaderSource: Vertex shader for rendering text. textFragmentShaderSource: Fragment shader for rendering text. Functions framebuffer_size_callback: Adjusts the viewport when the window size changes. processInput: Handles user input. compileShader: Compiles a shader from source code. createShaderProgram: Links vertex and fragment shaders into a shader program. renderGraph: Renders the graph using the provided data. renderAxes: Renders the axes of the graph. renderText: Renders text using the provided font and shaders. Main Function Initializes GLFW and creates a window. Sets up OpenGL context and loads GLAD. Compiles and links shaders. Sets up vertex data and buffers. Enters the render loop, which: Processes input Clears the screen Renders the graph and text Swaps buffers and polls for events stb_truetype Integration The stb_truetype.h library is used for font rendering. Font data is baked into a texture for efficient rendering. Contributing Contributions are welcome! Please fork the repository and create a pull request with your changes.
