Seminars on Computer Graphics 2 (Summer 2014)

Rules / Info

• On every seminar we will implement selected problems/algorithms related to lessons. We will usually - not necessary start with a prearranged template downloadable from this site.
• As a programming language we will use C#. We will use Visual C# 2010 as development environment. Alternatively you can use MonoDevelop (Linux / Mac OSX) on your own machine.
• Attendance at seminars is optional but recommended.
• Seminars are conducted by
  • Matej Hudak (subseth.mato@gmail.com)
• Schedule of seminars is
  • Wed (17:20) - Room I-H3
• Other collaborators and authors: Juraj Onderik

Homeworks

• You can get max 100% per homework. Submission after deadline is for 0%.
• There is a min 50% of your final evaluation required for admission to final term.
• Additional activity can be awarder by max 10% of your final evaluation.
• Don't cheat - create instead. Any kind of cheating is punished by withholding 30% of your final evaluation for all involved students.
• As a homework, you will program what we could not finish during the exercise. Assignment and template will be downloadable from this site. See exercises.
• Homework must be submitted by email to cg2.2014.hw@gmail.com every week until the next Wednesday 17:20.
• Your submission email must have title in form 'ExNN' where NN is the number of exercise, eg. Ex05.
• It is required to submit zipped source code of your homework (preferably the whole solution). Do not send executable files. Homework without the source code is for 0%.
• Your code should be well formatted and commented. Titles of functions, classes, variables should be representative for their purpose. Homework without appropriate comments is for 0%.
• There are ~12 homeworks during the semester. This number can change due to holidays, tech. problems etc.
• Your Evaluation

Exercise01 [26.02.2014] "Ray Casting"

• Implement a camera class suitable for the ray casting method. As usual you should use a similar functionality as in the sample application. Application should specifically be able to:
  • Render the scene (objects are movable).
  • Move the camera in a 3D space.
  • Change the camera's field of view (larger angle = more space to render), see Blender camera.
• Try to change the color of the intersected object due to distance from the camera
• '[2 bonus %]:
  • Create a camera which will rotate around defined point P (target) along a sphere with r = 1. You can use ideas from the Blender camera system and / or two-angle camera in openGL. Camera should use some sort of interactivity (2 angles) and targeted point P should be movable. Bonus camera can be created in a separated solution or you can change the structure in the template to implement two different cameras.
• Sample | Template
• Deadline: 12.3 - 17:20

Exercise02 [12.03.2014] "Primitives"

• Improve your tracer by adding a few primitives (ring, sphere, AABB box, triangle) [1] [2] [3]. Each object should be movable. As usual you should use a similar functionality as in the sample application.
• '[1 bonus %]:
  • Create also an infinite cylinder and infinite cone primitives
