== 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
** Michal Piovarči (cg2.2015.hw@gmail.com, Room M113)
* Schedule of seminars is
** Wed (16:30) - Room I-H3


== Homeworks ==
* You can get '''max 100% per homework'''. Submission after deadline is for 0%.
* There is a '''min 60% 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 [mailto:cg2.2015.hw@gmail.com cg2.2015.hw@gmail.com] every week until the '''next Wednesday 16:30'''.
* 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.

* Implement accelerating structure for ray tracing. The structure is KD Trees + surface area heuristic (SAH) [http://www.sccg.sk/~durikovic/classes/CG2/Handouts/CG03-kdtrees.pdf] (4.4.2). The dimension is 2. Go. As usual you should use a similar functionality as in the sample application [http://www.sccg.sk/~durikovic/classes/CG2/Handouts/CG03RT-II.pdf].
* Physically based rendering could help [http://www.amazon.com/Physically-Based-Rendering-Second-Edition/dp/0123750792]
* [http://www.sccg.sk/~hudak/CG2/Ex07.Sample.zip Sample] | [http://www.sccg.sk/~hudak/CG2/Ex07.Template.zip Template]
*'''Deadline:''' 07.5. - 17:20
* ''''[6 special bonus %]:'''
** Improve acceleration with KD Trees and SAH. Use it in 3D ray tracer for rendering mesh. Implement mesh loader and load the mesh from external source (e.g. stanford bunny - .obj format). You can use the standard mesh definition - everyting is a triangle.
** '''Special bonus deadline:''' 17.5. - 23:59
* '''[3 special bonus %]:'''
** Implement mesh loader and load the mesh from external source (e.g. stanford bunny - .obj format). You can use the standard mesh definition - everyting is a triangle. Implement UV mapping (uv coordinates from .obj format) and smooth shading on mesh.

= PRAX Practical Excercise in Company =

'''Stručná osnova predmetu:'''
Študent si sám vyhľadá vhodnú firmu alebo vedeckú inštitúciu, ktorá pracuje v oblasti informačných technológii a predloží svoj návrh na schválenie garantovi. Študent absolvuje predmet podľa pokynov inštitúcie.
Cieľom predmetu je aby sa študent oboznámil s novými IT technológiami, zariadeniami, naučil sa s nimi pracovať, obsluhovať a prevádzkovať ich.
Ako podmienkou na získanie hodnotenia študent vypracuje a odovzdá písomnú spravu potvrdenú zodpovedným vedúcim v inštitúcii pozostávajúcu z:
1. Potvrdenia dochádzky min 150 hodín v trvaní 9 týždňov t.j. dochádzkové listy
2. Správu o činnosti alebo výkazové listy s presným popisom činností
Hodnotenie za prax, ktorej minimálna dĺžka je 9 týždňov (150 hodín), po jej ukončení zapisuje garant. Prax je možné absolvovať kedykoľvek v priebehu 1. a 2. ročníka magisterského štúdia, najneskôr však do termínu, ktorý je stanovený koncom skúšobného obdobia daného semestra.

== What you Need to Pass ==
* Predbežný návrh firmy a práce pred zápisom alebo nástupom praxe.

* Potvrdenia od zamestnávateľa
1. Potvrdiť dochádzku 150 hodín a 9 týždňov, projekty na ktorých ste pracovali a hlavné IT technológie s ktorými ste pracovali.

* Správu o priebehu praxe napíše študent.
1. Uvedie všetky základné informácie o firme názov, adresu, ičo, dič, počet zamestnancov na Slovensku, odvedené dane za posledný rok, www. Toto sú bežne online dostupné informácie.
2. Mená projektových vedúcich, ktorý ho skolili a z akých IT technológii. Email a www, tel. kontakt na jedného školiaceho vedúceho.
3. Čo reálne vytvoril a koľko riadkov naprogramoval samostatne. Alebo akú inú činnosť vykonával ak testoval ako vytváral testy, čo bolo výsledkom? Ak ste robili výkazy tak túto časť viete vyskladať z výkazov.
