Bézier Surfaces & Realistic Rendering Techniques (Shader-based OpenGL)

Shader-based OpenGL program which draws Bézier surfaces (a type of mathematical splines, a 3D extension of Bézier curves) in wireframe, Gouraud Shaded, or Phong Shaded form, depending on the users choice. User can apply shading methods and rendering techniques to Bézier Surfaces.

Requirements

• OpenGL 3.2 +

Features

• User should click the screen to make dots.
• By using 'w'(+) and 's'(-) keys you can determine z coordinate. When coordinates are determined, user should press the 'a' key to add point.
• User should press 'b' key to draw bezier surface.
• User can apply the following functionalities and methods through menu
  • Camera controls (rotation, zoom in/out)
  • Shading methods (Wireframe, Gouraud shading, Phong shading)
  • Rendering techniques (Parametric Texture Mapping, Bump Mapping, Environment Mapping)
