A Dobby PhotoJob

My program containing solutions to all the projects/labs from the course Computer Graphics 1.

Main topics covered:

Lab 1 : Functional and Convolutional Filters

Home part:

• Functional Filters:

  • Inversion
  • Brightness Correction
  • Contrast Enhancement
  • Gamma Correction

• Convolution Filters:

  • Blur
  • Gaussian Smoothening
  • Sharpen
  • Mean Removal Sharpen
  • Edge Detect (Left to Right)
  • Emboss (East)

Lab part:

• Median Filter

Scores:

• Overall: 20/20
  • Home: 15/15
  • Lab: 5/5

Lab 2 : Dithering and Quantization

Home part:

• Average Dithering
• Octree Color Quantization

Lab part:

• Average Dithering using YcBcR

Scores:

• Overall: 20/20
  • Home: 15/15
  • Lab: 5/5

Lab 3 : 2D Graphics - Drawing

Home part:

• Line drawing: Symmetric Midpoint Line algorithm
• Circle drawing: Midpoint Circle (v.2, additions only) algorithm
• Drawing Thickness: Pixel Copy algorithm
• Anti-Aliasing: Goupta-Sproull algorithm

Lab part:

• Anti-Alisaing: 2x Super Sampling (then drawing and then downsampling for Anti-Aliasing).

Scores:

• Overall: 18/20
  • Home: 13/15 (Lost points because of missing some non-algorithmic functionality i.e. only being able to move vertices one-by-one, not whole shapes.)
  • Lab: 5/5

Lab 4 : 2D Graphics - Clipping and Filling

Home part:

• Clipping Polygons: Sutherland-Hodgman
• Filling Polygons: Vertex Sorting

Lab part:

• Flood filling: Boundry Fill

Scores:

• Overall: 20/20
  • Home: 15/15
  • Lab: 5/5

Lab 5 : 3D Graphics

(CPU Intensive and uses Affine transformations for the transformations).

Lab part:

• Implement a rotating 3D cube made of only edges from a distance (POV on Z-axis).

Home part:

• Textured Sphere: Textured 3D Sphere which can be moved around (and also POV can be moved around). We create a Triangular Mesh on/for the sphere and then fill with the texture.

Scores:

• Overall: 20/20
  • Home: 14.5/15 (some weird/random bug caused negative 0.5 points)
  • Lab: 5/5
