This page contains materials for the practice lessons of the [[https://is.cuni.cz/studium/rozvrhng/roz_predmet_gl.php?gl=14bNPGR019p1&fak=11320&skr=2014&sem=2|Hardware for Computer Graphics (NPGR019)]] course that is/has been taught during summer term 2014/2015 at [[http://www.mff.cuni.cz/|Charles University]] in [[http://www.praha.eu/jnp/cz/home/magistrat/index.html|Prague]], Czech Republic. The course official web page is/was to be found [[http://cgg.mff.cuni.cz/lectures/npgr019.cz.php|here]]. The lecturer is/was [[http://cgg.mff.cuni.cz/~pepca/|Jozef Pelikan]]. The practice lessons (workshops) are/were (mainly) backed up by [[https://gamedev.cuni.cz/contacts/|Jakub Gemrot]].

======Dates======

Tuesdays's workshops, 10:40, SW1, Jakub Gemrot: [[mailto:gemrot@gamedev.cuni.cz|gemrot@gamedev.cuni.cz]]


======How to pass the practice======

You will have to experiment with OpenGL at home by doing assignments that will be associated with every workshop. You do not need to solve all of them, see [[http://artemis.ms.mff.cuni.cz/gemrot/lectures/hwgr/2015/HWGR-2015-Workshops.xlsx|assignments & scoring]]. Note that you may receive BONUS points for finishing assignments on time!

You will need to gather at least N points in order to be admitted to final exam. Moreover, if you gather at least M points, you will receive bonus points during exam (10%) and if you manage to gather at least P points, you will receive even more bonus points (25% total).

  * note that Sixth edition is about OpenGL 4.3 so it does not apply to our workshops directly 
  * you might be interested in Fifth edition instead [[http://www.openglsuperbible.com/previous-editions/|OpenGL Superbible Book previous versions]]
    * right, there are no "download links" there ... hmmmmmm

[[http://www.directxtutorial.com/|DirectX Tutorials - paid]]
  * First 5 or so tutorials are free, good place start as it takes you through the first steps of D3D initialization

  * Many tutorials from the basic to complex ones
