Seminars on Advanced Computer Graphics

On wednesdays at 9:50 On Teams

Guide: Adam Riečický

Contact: adam.riecicky@fmph.uniba.sk

Info

Each week a short guided presentation will be given.

An assignment for every week will be finishing a template C# project. The deadline for every project is on the next successive Wednesday at 23:59. Consultations possible during the seminar time window.

Grading

  • Finishing project template = 10 points (late submission is for 0, no discussion)
  • Total 80 points make half of your final grade!
  • Minimum of 50% from exercises is required to finish the class successfully

Project Submittion

  • Your code should be well formatted and commented. Titles of functions, classes, variables should be representative of their purpose.
  • Submission email must have the subject in the form of 'ACG ExNN' where NN is the exercise id, eg. ACG Ex05.
  • Solution source codes have to be archived and named properly 'ExNN_YourName'
  • Do not archive send executable files.

Exercises

Exercise01 "Vectors and Matrices"

Asignment: Create a simple application for vector(4x1) and matrix operations(4x4). Use struct properties, functions and/or operators. Create a calculator, check your equations and results. Add implementation to theese files in folder ./Mathematics/ : Vector4.cs, MathEx.cs, and "Matrix44.cs

You can ignore vector operations "/" (vector projection) and "^" (modulation product).
