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 right before the next successive seminar - Wednesday at 9:50. The extended deadline is a week after with 0.5x penalization. Solutions to bonus assignment can be submitted anytime during the 2 weeks without the penalization.

Grading

  • Total points from exercises make half of your final grade!
  • Minimum of 50% from exercises required to finish the class successfully
  • Late submission is for 0, no discussion

Project Evaluation Criteria

  • 10 pt => Correct submission, everything works as supposed.
  • 6 pt => Partially correct submission, most of the things work as supposed.
  • 3 pt => Partially correct submission, at least one core functionality correct.
  • 0 pt => Incorrect submission or unsubmitted.
  • Penalization 0.5x when submitting in extended deadline (not for bonus).

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

Exercise00 "Vectors and Matrices"

Deadline (no extended deadline): 3.3.2021 at 23:59

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).

For a help, see this reminder on linear algebra


Exercise01 "Ray Casting"

Deadline (no extended deadline): 10.3.2021 at 23:59

Seminar slides

Asignment: Implement basic ray casting and the intersection of ray and plane. Define the camera class and implement a simple ray-tracing procedure.

Bonus [2 bonus %]: Create a camera that will rotate around defined point P (target) among a sphere with r = 1. You can use ideas from the Blender camera system and/or two-angle camera in OpenGL. The camera should use some sort of interactivity (2 angles) and targeted point P should be movable. Bonus camera can be created in a separate solution or you can change the structure in the template to implement two different cameras.


Exercise02 "Primitives"

Deadline: 10.3.2021 at 9:50 Extended deadline: 17.3.2021 at 9:50

Seminar Slides

Asignment: Improve your tracer by adding new primitive object types: box, sphere, and ring.

Resources: Planes, triangles, and distances, Intersection algorithms

Bonus [3 bonus % (1 for each)]: Create also a triangle, cylinder, and cone primitives and add them to the tracer. Also, create a new scene where you present the primitive(s).


Exercise03 "Shaders, Shading and Shadows"

Deadline: 17.3.2021 at 9:50 Extended deadline: 24.3.2021 at 9:50

Seminar Slides

Asignment: Improve your tracer by implementing Phong and checker shaders, directional light, and hard shadows. Compute normals of each primitive at the point of intersection. As usual, you should use a similar functionality as in the sample application.


Exercise04 "Light Types"

Deadline: 24.3.2021 at 9:50 Extended deadline: 31.3.2021 at 9:50

Seminar Slides

Asignment: Improve your tracer by adding a point, spot and an area light types. In the case of point and spotlight, define the light as a point with hard shadows and linear/quadratic light attenuation [2]. Area light could be defined by Lights x Lights point lights. Area light should also be able to produce "soft" shadows.

[2 bonus %]: Write an equation for illumination computed by sample code from seminar slides


Exercise05 "Shaders"

Deadline: 31.3.2021 at 9:50 Extended deadline: 7.4.2021 at 9:50
