CKShetty4/OpenGL_Template

OpenGL project template provides a simple starting point for developing applications using OpenGL, GLFW, and GLEW

OpenGL Template

Overview

This is a simple OpenGL template using GLFW, GLEW, and GLAD. The template provides a basic setup for creating an OpenGL window, rendering a simple triangle, and setting up the necessary dependencies.

Prerequisites

Ensure you have the following installed before using this template:

• Visual Studio (Recommended: 2022 or later)
• OpenGL-compatible GPU and drivers

Setup Instructions

Follow these steps to configure project properties for OpenGLProject in Microsoft Visual Studio:

1. Open the Project

1. Open Visual Studio and load OpenGLProject.sln.
2. Navigate to View > Solution Explorer.
3. Right-click on OpenGLProject in the Solution Explorer.
4. Click Properties.

2. Configure General Settings

1. In the OpenGLProject Property Pages, select the Configuration and Platform options as required.
2. Expand the C/C++ section in the left panel and click General.
3. Set Additional Include Directories to:

   $(SolutionDir)Dependencies\GLFW\include;
   $(SolutionDir)Dependencies\GLAD;
   $(SolutionDir)Dependencies\GLEW\include\GL;
   %(AdditionalIncludeDirectories)

3. Define Preprocessor Settings

1. Navigate to C/C++ > Preprocessor.
2. Add the following to Preprocessor Definitions:

   GLEW_STATIC; *(Ensure other required definitions are present.)*

4. Configure Linker Settings

1. Expand the Linker section and click General.
2. Set Additional Library Directories to:

   $(SolutionDir)Dependencies\GLEW\lib\Release\x64;
   $(SolutionDir)Dependencies\GLFW\lib-vc2022;
   %(AdditionalLibraryDirectories)
   

• Screenshot:

1. Click Input under Linker and set Additional Dependencies:

   $(CoreLibraryDependencies);
   %(AdditionalDependencies);
   glfw3.lib;
   opengl32.lib;
   glew32s.lib;
   

2. In the same section, set Ignore Specific Default Libraries to:

   MSVCRT.lib

5. Open and Build the Project

1. Navigate to Source Files in Solution Explorer.
2. Open main.cpp.
3. Use the following shortcuts to compile and build:
   • Ctrl + Shift + B → Build the project.
   • Ctrl + F7 → Compile the project without running.

(These shortcuts apply to Windows; for other platforms, refer to respective IDE settings.)

Once completed, the OpenGLProject should be successfully configured and ready for execution.

Features

• Uses GLFW for window and input handling.
• Uses GLEW to load OpenGL functions.
• Uses GLAD for OpenGL function management.
• Renders a simple color-interpolated triangle.
• Supports easy modification and extension.

Modifying the Template

• Modify main.cpp to add your own rendering logic.
• The rendering section is marked between:

  /* START MODIFYING HERE */
  /* END MODIFYING HERE */

• Add shaders, models, or textures as needed.

Platform-Specific Notes

Windows

• All dependencies are pre-included; no additional installations are required.

Linux & MacOS

• You may need to manually install GLFW, GLEW, and GLAD using package managers.
• Adjust include and library paths accordingly in project settings.
