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.

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

Implemented the plane selection using density grid

I've implemented the plane selection procedure described in Image-Based Rendering of Forests

Currently working on

Working on optimizing the selection procedure.
