What you'll learn

  • Understand the fundamentals of WebGL – grasp how WebGL works and the core principles behind rendering 3D graphics in the browser.
  • Create and visualize 3D objects – use buffers, attributes, and shaders to render simple and complex models.
  • Work with textures and lighting – apply texture mapping, implement lighting techniques (Phong, Gouraud), and create reflection and refraction effects.
  • Implement animations and user interactions – control the camera, handle keyboard and mouse input, and build interactive 3D scenes.
  • Optimize rendering performance – reduce computational load, manage memory efficiently, and enhance graphics performance for smooth real-time rendering.
  • Develop and deploy a complete WebGL project – integrate a user interface, refine the experience, and publish the project online.
