Practical Seminars on Computer Graphics 1 (Winter 2011)

  • On every seminar we will implement selected problems/algorithms from lessons. We will usually start with a prearranged template downloadable from with site.
  • As a programming language we will use C#. We will use Visual C# 2010 Express as development environment. Alternatively you can use MonoDevelop (Linux / Mac OSX) on your own machine.
  • Your code should be well formatted and commented. Titles of functions, classes, variables should be representative for their purpose.
  • Every week you have to finish and submit the assignment as homework.
  • At the end of the semester you have to submit the project.
  • Any kind of cheating is punished by withholding 15 points for all involved students. Situation where only part of code is shared is also considered cheating!
  • Attendance at seminars is optional but recommended. Your activity during seminar can be awarded with max 5 bonus points during the semester.
  • Seminars are conducted by
    • Matej Hudak (subseth.mato@gmail.com)
    • Juraj Onderik (wonderik@gmail.com)
  • Schedule of seminars is
    • Tue (8:10) - Room H6
    • Tue (18:10 - Room H3
    • Wed (18:10) - Room F248

Homeworks

  • As a homework, you will program what we could not finish during exercise. Assignment and template will be downloadable from this site. See exercises.
  • Homework must be submitted by email to cg1.2011.hw@gmail.com every week until next monday 23:59.
  • Your submission email must have title in form 'ExNN' where NN is the number of exercise, eg. Ex05.
  • You can get max 3 points per homework, totally 33 points. Late submission is for 0 points.
  • It is required to submit zipped source code of your homework. Do not send executable files. Homework without source code is for 0 points!

Project

  • Project must be submitted by email to cg1.2011.hw@gmail.com until 15.1.2011.
  • You can get max 12 points for your project.
  • It is required to submit source code of your project. Executable files are optional. Projects without source code is for 0 points!
  • Project assignment
    • TODO

Seminars

Exercise01 [20/21.9] "Introduction"

  • There are no points for this seminar.
  • csharp tutorials
  • visual c# tutorials
  • Visual Studio Tips
    • F2: Rename object/class/property/field...
    • F5: Build and debug solution
    • Shift + F5: Stop debugging solution
    • F9: Add/Remove break-point at current line
    • F12: Navigate to definition/declaration of object/class...
    • CTRL + Space: List members of object/class after "." or parameters of method after "("

Exercise02 [27/28.9] "Vectors and Matrices"

  • Introduction to C#
  • classes: Vector3, Matrix33
  • Add(V3, V3), Sub(V3, V3), Cross(V3, V3), Dot(V3, V3)
  • Add(M3, M3), Mul(M3, M3), Sub(M3, M3)
  • Mul(M3, V3), Mul(V3, M3)
  • Gui calculator:
    • 3x1 vector (operator) 3x1 vector = 3x1 vector
    • 3x3 matrix (operator) 3x3 matrix = 3x3 matrix
  • Assignment
    • Create a simple application for vectors(3x1) and matrices(3x3). Create classes Vector3 a Matrix33. Create GUI according to final sample. Implement operations for vectors: W = U + V, W = U - V, W.X = Dot(U,V), W = Cross(U,V), W.X = U.Length and for matrices: C = A + B, C = A - B, C = A * B, W = A * V, W = U * B. Implement them as operators '+', '-', '*',.. Create calculator application with all operations working similar as in final sample.

Exercise03 [04/05.10] "Transformations 1"

  • classes: Vector4, Matrix44, Polyline
  • A.Transpose(), A.Inverse(), A.Determinant()
  • RotateX/Y/Z/XYZ
  • Translate(K), Scale(K)
  • Drawing
    • Polyline
    • Free
  • Assignment
    • Create a simple application with transformations and drawing. In transformations implement operations in Matrix44 labeled 'To Do'. In drawing implement free drawing using mouse left button_(down, move, up). Fill all sections labeled 'To Do'. Create 'Clear All' button. Create final application with all operations working similar as in final sample.

Exercise04 [11/12.10] "Transformations 2" (Onderik)

  • Implement definition and modification of simple polyline objects. Following functionality have to be implemented based on the mouse butons and modifier keys.
  • Left MB: Select pivot of one closest polyline.
  • Left MB + SHIFT: Select more pivots.
  • Left MB + CTRL: Create and place new polyline at the mouse cursor.
  • Left MB + ALT: Add new point to the first selected polyline at mouse cursor.
  • Right MB: Move seleted polylines in plane XY.
  • Right MB + CTRL: Rotate selected polylines around Z-axis in XY plane.
  • Right MB + SHIFT: Scale selected polylines uniformely in XY plane.

Exercise05 [18/19.10] "Projection" (Hudak)

  • Implement 3 types of projection: orthogonal, perspective and parallel. Use Help to assign correct polyline to correct projection. Implement method to defined segment of projection line as projection of polyline 3(orange). Methods have to be a projections by definition and they also should be transparent to interaction with polylines(during rotation, scale or translate).
