RDHR Project

This page contains information about the Radiance Decomposition Hierarchical Radiosity (RDHR) research project.

Subversion Repositories

• C# (as a fork of LightFairy library)
• C++

Obtaining the Source

Installing Subversion and Tortoise SVN

Please grab Subversion from this page. You may also wish to download Tortoise SVN, which provides a nice integration between Subversion and Windows Explorer, from here.

Checking Out the Trunk

To check out, execute the following common in your shell:

svn checkout http://theory.cpe.ku.ac.th/pramook_rdhr-c++/trunk <directory>

This will download all the latest version of the files to the directory <directory>.

Creating a Branch

The directory "trunk" is supposed to contain stable code. New code shall be developed independently in different branches private to each member of the team. These branches will be merged into the trunk after members agree on how to integrate their codes. Hence, it's important that you create a branch for yourself.

Suppose you're going to create a branch named "my_branch." Execute the following command:

svn copy http://theory.cpe.ku.ac.th/pramook_rdhr-c++/trunk http://theory.cpe.ku.ac.th/pramook_rdhr-c++/branches/my_branches -m "create my_branch"

Notes on Building the C++ Version

Requirements

You need the following software:

• Microsoft Visual C++ Express 2005. Grab it here.

It's important that you use VC2005 because CUDA only work with Microsoft C compiler 6.0 or 7.1, which comes with VC2003 or VC2005. I use VC2005 now, and the repository contains VC2005 project files.

• Microsoft Windows Server 2003 R2 Platform SDK. Grab it here.

This is the newest Windows SDK I could find.

Please install them and DO NOT alter their installation directories. The reason is that the Windows SDK include directory is hard-coded into rdhr-c++ project files.

Cannot open precompiled header file error

When building the "rdhr" project, you might get an error message like this:

C1083: Cannot open precompiled header file: 'Debug/<Project-Name>.pch': No such file or directory.

To make it go away, compile "stdafx.cpp" alone first, then build the project.

UnitTest++.vsnet2005 and TestUnitTest++.vsnet2005

Sometimes these two projects will be unloaded when you open the solution. If you have not built these two projects on your local machines, please load and build them.

UnitTest++

Information on UnitTest++, the unit testing framework I'm using, can be found here.
