Next follows the abstract:</P>29 <BLOCKQUOTE>In the proposed tutorial we would like to highlight the connection between rendering algorithms and sorting and searching as classical problems studied in computer science. We will provide both theoretical and empirical evidence that for many rendering techniques most time is spent by sorting and searching. In particular we will discuss problems and solutions for visibility computation, density estimation, and importance sampling. For each problem we mention its specific issues such as dimensionality of the search domain or online versus offline searching.

Next follows the abstract:</P> 29 <BLOCKQUOTE>In the proposed tutorial we would like to highlight the connection between rendering algorithms and sorting and searching as classical problems studied in computer science. We will provide both theoretical and empirical evidence that for many rendering techniques most time is spent by sorting and searching. In particular we will discuss problems and solutions for visibility computation, density estimation, and importance sampling. For each problem we mention its specific issues such as dimensionality of the search domain or online versus offline searching. We will present the underlying data structures and their enhancements in the context of specific rendering algorithms such as ray shooting, photon mapping, and hidden surface removal.</BLOCKQUOTE> 30 <P>Some <B>pictures</B> of the different events:</P> 31 31 <P><A HREF="../game.jpg"><IMG ID="Picture2" HEIGHT=142 WIDTH=200 SRC="../assets/images/game_th.jpg" VSPACE=0 HSPACE=0 ALIGN="TOP" BORDER=0 ALT="game_th" TITLE="game_th"></A> <A HREF="../tshirts.jpg"><IMG ID="Picture4" HEIGHT=125 WIDTH=200 SRC="../assets/images/tshirts_th.jpg" VSPACE=0 HSPACE=0 ALIGN="TOP" BORDER=0 ALT="tshirts_th" TITLE="tshirts_th"></A> <A HREF="../presentation.jpg"><IMG ID="Picture5" HEIGHT=150 WIDTH=200 SRC="../assets/images/presentation_th.jpg" VSPACE=0 HSPACE=0 ALIGN="TOP" BORDER=0 ALT="presentation_th" TITLE="presentation_th"></A></P> 32 <P>The poster:</P>32 <P>The <B>poster</B>:</P> 33 33 <P><A HREF="../EG06poster.png"><IMG ID="Picture6" HEIGHT=211 WIDTH=300 SRC="../assets/images/EG06poster_th.png" VSPACE=0 HSPACE=0 ALIGN="TOP" BORDER=0 ALT="EG06poster_th" TITLE="EG06poster_th"></A></P> 34 34 </TD> … … 50 50 <TD WIDTH=732 CLASS="News"> 51 51 <P><I>8 / SEP /2006</I> - <B>GAMETOOLS</B> sponsored the <A HREF="http://www.cg.tuwien.ac.at/events/EG06/graphicsmeetsgames.php"><B><I>Graphics meets Games</I></B></A> competition at <A HREF="http://www.cg.tuwien.ac.at/events/EG06/index.php">Eurographics 2006</A> in Vienna.</P> 52 <P> 53 <TABLE WIDTH="100%" BORDER=0 CELLSPACING=0 CELLPADDING=0 NOF=TE> 54 <TR> 55 <TD ALIGN="CENTER"><A HREF="http://www.cg.tuwien.ac.at/events/EG06/graphicsmeetsgames.php"><IMG ID="Picture7" HEIGHT=104 WIDTH=600 SRC="../assets/images/EG06GmGGTPweb.png" BORDER=0 ALT="Graphics meets Games" TITLE="Graphics meets Games"></A></TD> 56 </TR> 57 </TABLE> 58 </P> 52 59 </TD> 53 60 </TR> … … 58 65 <TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 NOF=LY> 59 66 <TR VALIGN=TOP ALIGN=LEFT> 60 <TD WIDTH=17 HEIGHT=2 8><IMG SRC="../assets/images/autogen/clearpixel.gif" WIDTH=17 HEIGHT=1 BORDER=0 ALT=""></TD>67 <TD WIDTH=17 HEIGHT=26><IMG SRC="../assets/images/autogen/clearpixel.gif" WIDTH=17 HEIGHT=1 BORDER=0 ALT=""></TD> 61 68 <TD></TD> 62 69 </TR> … … 67 74 <TR> 68 75 <TD CLASS="News"> 69 <P><I>22 / A GO/2006</I> - Dr. Michael Wimmer presented the <B>GAMETOOLS</B> project at <A HREF="http://www.gcdc.de/">GCDC in Leipzig</A>, the biggest event for game developers in Europe, in a panel discussion that had collaboration between academia and industry as a topic.</P>76 <P><I>22 / AUG /2006</I> - Dr. Michael Wimmer presented the <B>GAMETOOLS</B> project at <A HREF="http://www.gcdc.de/">GCDC in Leipzig</A>, the biggest event for game developers in Europe, in a panel discussion that had collaboration between academia and industry as a topic.</P> 70 77 </TD> 71 78 </TR> -
