.obj rendering with OpenGL 4.1
Grade (TBD/100) (TBD/125)*

Goals:
  • Code in C, observing 42's norm (see below)
  • Use modern OpenGL, >=4.0 with shaders
  • Parse and render a .obj file
  • Rotation around y axis
  • Apply grey shades on each faces
  • Apply a texture on the object
  • No math/3d library allowed
Recommended bonus:
  • Handle any .obj
  • Smart texture projection
My work:
  • Watched a course from UC Davis on youtube (see below)
  • Read Learn OpenGL website (see below)
  • Used GLFW for window handling
  • Matrix operations
  • Randomly generated land at startup. Built on GPU
  • Blinn–Phong single source lighting. Represented with a movable yellow sun
  • Shadows with depth cubemap
  • Tesselation on sun from a tetrahedron to a sphere. (Automatic or controls with keyboard)
  • Tesselation on land from {color,height,normal}maps generated at startup
  • Advanced mesh processing
  • Multiple texture projections
  • Dynamic controls for object/textures/texture-projection-mode/mesh-processing/camera-potion/object-position/sun-position/sun-tesselation
