Contents of COLLADA Package 
==============================================================================

This package includes the COLLADA DOM and the COLLADA Viewer.  Everything in 
this package can be built to run on either PS3 or a Windows PC.  For additional 
information on tools and plugins that support COLLADA, or to get help from the
Internet community of COLLADA users, please visit www.collada.org  

The COLLADA DOM is a set of libraries for loading and saving COLLADA documents
that can contain 2D, 3D, physics and other types of content. It allows developers 
to create applications that can exchange COLLADA documents with commercial content 
creation tools such as Maya, Max or Softimage.  

The COLLADA Viewer is a general purpose 3D viewer for COLLADA documents.  It is
provided as sample code to show how to use the COLLADA DOM and to demonstrate
the kinds of content that can be stored in a COLLADA document.  The included
sample COLLADA documents can be loaded into the Viewer to demonstrate these
features.  The COLLADA Viewer and its sample documents replace all the 
hard coded COLLADA demos that were included with older PS3 releases.

   viewer.self will be in viewer\bin for release build (conf=release, this is the default build)
   viewer.self will be in viewer\bin for debug build (conf=debug)
2) Unzip samples.zip, extract its content to viewer\bin\
3) Use ProDG Target Manager or Debugger to load viewer.self 
   Optionally, specify a COLLADA document (cage.dae) as command line argument when loading viewer executable


[Windows host/Visual Studio]
Project files for Visual C++ 8 (VS 2005) and Visual C++ 9 (VS 2008) are both provided. If you are using Visual C++ 9,
substitute "vc9" for "vc8" for the following instructions.

2) Select "PS3 debug" or "PS3 release" configuration to build PS3 target
3) Unzip samples.zip, extract its content to viewer\bin\
4) Use ProDG Target Manager or Debugger to load viewer.ppu.self (release) or viewer-d.ppu.self in \viewer\bin
   Optionally, specify a COLLADA document (cage.dae) as command line argument when loading viewer executable

[Linux]
1) Execute make utility at root level of package by typing 'make'
   viewer.self will be in viewer/bin for release build (conf=release, this is the default build)
   viewer.self will be in viewer/bin for debug build (conf=debug)
2) Unzip samples.zip, extract its content to viewer/bin/
3) Change directory to where the COLLADA Viewer executable is, type the following commands to load it, replace
   the IP address with your PS3 IP address.
   
	> bedbg -prepare
	> dtpon -d 10.98.12.34
	> bedbg -nodebug viewer.self
	
	Type the following commands to terminate COLLADA Viewer

==============================================================================
Building the COLLADA package and running the COLLADA Viewer sample for Windows
==============================================================================

These instructions will build the entire contents of the COLLADA package including
libraries and samples for Windows.  All the libraries needed to build for Windows
are included in this package or come with Visual Studio.  The instructions include 
running the COLLADA Viewer which can be used to view any of the included sample 
COLLADA documents.

Project files for Visual C++ 8 (VS 2005) and Visual C++ 9 (VS 2008) are both provided. If you are using Visual C++ 9,
substitute "vc9" for "vc8" for the following instructions.

1) Open Visual Studio Solution at \viewer\projects\vc8-Win\viewer.sln
2) Select "Debug" or "Release" configuration to build Windows executable
3) viewer.exe (release) or viewer-d.exe(debug) will be in \viewer\bin
4) Unzip samples.zip, extract its content to \viewer\bin\
5) Open up a DOS Shell window, change directory to \viewer\bin, type "viewer.exe duck.dae" to view COLLADA document "duck.dae"

How To use SPU-Optimized Bullet 2.73
====================================

By default, the PS3 COLLADA viewer does not run with physics simulation.  You could enable the SPU-optimized physics simulation on PS3 
with the following changes:

1) Download and install the Bullet package
   a. Download open source bullet-2.73-*.zip from http://code.google.com/p/bullet/downloads/list
   b. Unzip bullet-2.73 in ${YOUR_BULLET_PATH} - any destination directory of your choice
   c. Download spubullet-2.73-*.zip from https://ps3.scedev
   d. Unzip spubullet-2.73-*.zip in the same directory of step (b)
   e. Refer to SPU_Optimized_Bullet-Quick_Start_Guide_e.pdf in the download package to build Bullet libraries and sample app


2) In 'rt' and 'viewer' projects, add SPU_BULLET to the Preprocessor Definitions field in the Preprocessor tab for the C/C++ project configuration settings.

3) In the 'rt' and 'viewer' projects, add the following line to the Additional Include Directories field in the General tab for the C/C++ project configuration settings:

	${YOUR_BULLET_PATH}\src


4) In the 'viewer' project, add the following lines to the Additional dependencies field in the Input tab for the Linker project configuration settings
												   
	${YOUR_BULLET_PATH}\src\Physics\TaskUtil\libtaskutild.a
	${YOUR_BULLET_PATH}\out\debug8_ps3\libs\libBulletcollision_d.a
	${YOUR_BULLET_PATH}\out\debug8_ps3\libs\libBulletdynamics_d.a
	${YOUR_BULLET_PATH}\out\debug8_ps3\libs\libBulletmath_d.a
	${YOUR_BULLET_PATH}\out\debug8_ps3\libs\libBulletmultithreaded_d.a
	${YOUR_BULLET_PATH}\msvc_ps3\8\PS3_PPU_Debug\PS3_SpuDispatch.lib
	-lspurs_stub


5) Right click 'viewer' project, add the following Existing items to the project to link with the Bullet SPU modules:

	${YOUR_BULLET_PATH}\out\debug8_ps3\libs\PS3_SPURS_BulletCD_spu.ppu.obj


Note: COLLADA viewer can be configured to run SPU-optimized collision detection, but not the SPU version of physics effects constraint solver.



=============================================
Release notes for COLLADA package, April 2009
=============================================

- Memory leak fixes in COLLADA 'fx' and 'rt' libraries

- Upgrade Bullet library to version 2.73 for Windows target

- Allow PS3 COLLADA Viewer to use SPU-optimized Bullet 2.73

- COLLADA DOM library name suffix changed from 2.1 to 2.2

- Added Windows x64 target for COLLADA Viewer

- COLLADA sample error correction (dominos.dae and morph.dae)

- New test case added to 'domTest' project

- Added 'samples.doc' to describe features of sample COLLADA documents



============
Known issues
============

- To keep the COLLADA Viewer sample code simple and portable across OS's, some user generated OS/windowing events are handled in modal way 
  that suspends running the core code of the Viewer.  When this happens, animations will stop utill the event is over, then will run very fast 
  for a short time as they catch up to the current realtime.  This is usually only noticable when dragging the Viewer window to a new location 
  in Microsoft Windows but may also occur briefly on other events such as windows being covered/uncovered.

- For PS3 debug build, when unloading COLLADA document with large number of nodes, such as demo.dae and dominos.dae,
  a debug exception is raised due to stack overflow.
  
  The COLLADA Viewer uses Cell SDK framework, which sets the main PPU thread priority and stack size in its code base.
  Currently there is no way to override this stack size setting without generating a linker warning on Windows host or 
  an error on Linux host.  See below:

  linker warning "L0019: symbol '__sys_process_param' multiply defined" is generated.
  
  To get around this problem, one can modify the Cell SDK framwork code in the following way:
  
  In <SDKROOT>\samples\fw\src\cell\FWCellMain.cpp, modify the line from 
	SYS_PROCESS_PARAM( 1001, 0x10000 );		// priority = 1001, stack size = 64K	
	
  to
  
	SYS_PROCESS_PARAM( 1001, 0x18000 );		// priority = 1001, increase stack size to 96K, or other setting to suit your need
