__Student:__ Mats Leksell (swx) __Mentor:__ Andres Carrera (Lioric) __Status:__ Experimental, obtain it from ogreaddons/billboardclouds !Overview The concept of billboard clouds were introduced by Xavier Décoret et al as a way of simplifying a complex model to a small number of view independent billboards while preserving the visible quality of the output. More information can be found here: [http://w3imagis.imag.fr/Publications/2003/DDSD03/index.gb.html|Billboard Clouds for Extreme Model Simplification] [http://www.vrvis.at/vr/billboardclouds|Forest rendering] !Objective Create an easy to use library for creating a billboard cloud from an input mesh. !Progress __Implemented a simpler plane selection algorithm__ ( as described here: [http://www.cs.utah.edu/~lacewell/billboardclouds/index.html] ) [http://img508.imageshack.us/img508/4417/top16cs.png] [http://img488.imageshack.us/img488/7048/left12rp.png] {img fileId="12" thumb="y" alt="left12rp.png" rel="box[g]"} [http://img508.imageshack.us/img508/369/front10el.png] __Implemented an image packing algorithm__ [http://img488.imageshack.us/img488/9306/packing4mn.png] {img fileId="13" thumb="y" alt="packing4mn.png" rel="box[g]"} __Implemented texture generation__ [http://img511.imageshack.us/img511/3391/bettertexture9ns.png] {img fileId="14" thumb="y" alt="bettertexture9ns.png" rel="box[g]"} __Implemented normal map generation__ [http://img135.imageshack.us/img135/7662/normalmap8yi.png] {img fileId="15" thumb="y" alt="normalmap8yi.png" rel="box[g]"} __Implemented the plane selection using density grid__ I've implemented the plane selection procedure described in [http://www.vrvis.at/TR/2004/TR_VRVis_2004_032_Full.pdf|Image-Based Rendering of Forests] !!Currently working on Working on optimizing the selection procedure.
