Lighting-and-Shading

Illuminating the scene with a point light source and implementing & comparing different lighting computation methods in OpenGL.

In this project we:

• Illuminate the scene by adding a point light source.
• Insert objects (cube/sphere).
• Compute per-vertex/per-fragment normals to the objects, to be used for lighting computations.
• Implement and compare the following shading techniques:
  • Gouraud shading for diffuse lighting.
  • Phong lighting -- by computing per-vertex normals and all three lighting components: ambient, diffuse, and specular (α = 64).
  • Phong shading -- by computing per-fragment normals and all three lighting components: ambient, diffuse, and specular (α = 64).

Results

1. Illuminate the scene by adding a point light source and objects (without shading):

   Cube	Sphere

2. Gouraud shading (diffuse lighting):

3. Phong lighting (per-vertex):

3. Phong Shading (per-fragment):

Execution

• Generate the object file:
  • mkdir build && cd build
  • cmake ..\
  • make
  • cd ../
• Execute the object file:
  • ./bin/lighting_and_shading
