==================
0 - Introduction
==================
YafRay comes as a command line raytracer and dynamic library for
integration into other applications (for example Blender).
Currently, YafRay does not feature a GUI.
Visit www.yafray.org for more information.
The command line syntax is:
yafray [options] file.xml
==================
1 - Installation Notes
==================
If you're using YafRay since first versions, please be careful with a
possible deprecated yafray.bat in your \windows folder.
It could make YafRay fails. You have to delete it.
To run the latest version, you need MSVCR71.dll because from 0.0.8 on
Yafray uses the dynamic runtime (mainly because of OpenEXR).
MSVCR71.dll is part of the Microsoft .NET Framework 1.1 available from:
http://msdn.microsoft.com/netframework/downloads/framework1_1/
==================
2 - YafRay Options
==================
-c N -> Where 'N' is the number of CPU's to use
(for multi-proccesor computers)
-z -> Use net optimized (under mosix clusters)
-p PATH -> Where 'PATH' is the installing path of YafRay.
(By default YafRay uses Windows registry to locate grammar file
and plugins, so this option is not needed (If all runs fine ;-) ).
-v -> Shows YafRay's version.
NEW since 0.0.6:
-r min_x:max_x:min_y:max_y -> Render region. Values between -1 and 1.
Whole Image is -r -1:1-1:1
To display the options, just type yafray and press ENTER
==============================
3 - HOW TO SET yafray.exe IN PATH
==============================
YafRay Installer doesn't add yafray executable to your PATH environment variable.
So if you wish execute YafRay from any directory you need add YafRay's installation
directory to the PATH variable yourself.
I will assume that YAFRAY_DIR contains the YafRay installation directory.
If example, if you have installed YafRay in c:\Program Files\yafray you must
change YAFRAY_DIR with c:\Program Files\yafray in the lines below.
* Setting the path in windows 95/98
-----------------------------------
- You need to be able to see hidden folders
- Click on "My Computer"
- Select "View" from the menu
- Select "Folder Options"
- In the window that pops up:
- Select the "View" tab
- Select "Show all files option"
- Select "Ok"
- Editing AutoExec.bat
- Open C:\AutoExec.bat with Notepad, Wordpad or other text editor
Two options:
1.- Append YAFRAY_DIR to the PATH variable.
2.- Add the following line to the bottom of your file:
SET PATH="YAFRAY_DIR";"%path%"
- Save and close
- RESTART Windows
* Setting the path in windows 2000/XP:
-----------------------------------
- Right click on my computer.
- Select "Properties".
- Click "Environment Variables".
If you have Administrative privileges then you can Edit the Path in
the System Variables box. If you do not have Adminitrative privileges
then you can Edit the PATH in the user variables box.
- Select the variable "PATH" or "Path".
- Click "Edit...".
- In the box "Variable Value:" go all the way to the end (as far right
as possible) you can do this by clicking in the box and then pressing
and hold in the right arrow on the keyboard. Once you are at the end
you will need to type the path to the executable program. You will
need to type (without the quotes): ";YAFRAY_DIR".
- Click "Ok".
- Click "Ok".
- Click "Ok".
================================
4 - CHANGELOG
================================
YafRay 0.0.9 is mainly a maintenance update.
Changes since 0.0.8 (all by Mathias Wein, Lynx in YafRay forums):
- new SAH-kdtree for mesh objects, which is hopefully mature now.
improvements include:
* smaller memory footprint
* more robust traversal, so holes in meshes should be history
* faster ray-scene-intersection (depending on scene) due to new
building algorithm (surface area heuristic and triangle clipping,
preparing scene can take a bit longer though)
- image loading code is more careful when trying to load files with
unknown extension (crash-fixes)
- Added -p command line option for Linux to specify an alternative
plugin path when rendering XML (yafray executable), YafRay also prints
used plugin path and number of plugins loaded to console now
- changing number of threads with blender plugin now takes effect
without restarting blender (blender 2.42 and later only)
- fixed some minor bugs, code cleanups/updates for newer compilers and
build-environments
