| === crontab on MacOS === | | ==Redesign of VTK== |
| * Example
| | The next version of VTK will support OpenGL 2.0 and GPU Filters. |
| crontab -e
| | The illustration below shows the new Rendering Pipeline of VTK. |
| 00 20 * * * ctest -S myScript.cmake > myScript.log 2>&1
| |
|
| |
|
| * Problem:
| | [[Image:ShaderDeviceAdapter.png]] |
| When I create a cronjob with
| |
| crontab -e
| |
| I get the error message:
| |
| crontab: temp file must be edited in place
| |
|
| |
|
| * Solution:
| | ==Streamline Visualization on the GPU== |
| Use the 'nobackup' option in VI:
| | Lines are converted to Triangle Strips on the CPU. |
| :set nobackup
| | Then the Vertex Shader orients the triangle strips to face the camera. |
| :set nowritebackup
| | Finally the Fragment Shader colors the pixels based on the reflection equation on a cylinder. |
| crontab: installing new crontab
| | The resulting image can be textured with arrows, text, or numbers to convey additional information. |

| === Install X11 on MacOS ===
| | [[Image:TubePainter.png]] |
| To install ParaView-2.4.4, you need to install X11.
| |
| * Insert 'Mac OS X Install Disc 1'
| |
| * Scroll down to 'Optional Installs'
| |
| * Click 'Continue', 'Continue', 'Accept'
| |
| * Select 'Applications', click on the arrow in front of Applications
| |
| * Select 'X11'
| |
| * Click 'Upgrade', enter your password, click 'Ok'

|
| === Setup CMake for ICC === | | ==Streamlines with a cylinder reflection model== |
| To configure a project to use the Intel compiler icc,
| | The Vertex Shader orients the triangle strips toward the camera. |
| set CC and CXX *before* you run cmake.
| | The FragmentShader applies a cylinder reflection model to give this tube appearance. |
| Type is the terminal:
| | [[Image:TestTubeActorStreamLines.png]] |
|
| |
|
| CFLAGS= CXXFLAGS=
| | ==Streamlines with arrows== |
| CC=/opt/intel_cc_81/bin/icc
| | The Fragment Shader creates a triangle and orients it based on the value of a vertex attribute. |
| CXX=/opt/intel_cc_81/bin/icpc
| |
|
| |
|
| Then run cmake or ccmake.

| === Headers for Cross-platform Projects === | | ==Streamlines with RGBA texture== |
| | The Fragment Shader applies a texture on the streamlines to visualize additional information. |
|
| |
|
| #include <stdio.h> // for sscanf

|
| === Install Qt OpenSource for VCExpress (VS2005) === | | ==Streamlines with numbers== |
| * Install VCExpress AND Platform SDK
| | Note that the numbers are oriented correctly on the Vertex Shader. The text always faces the camera even during rotations. |
| http://msdn.microsoft.com/vstudio/express/visualc/download/
| |
| * Using Windows Unzip, extract qt-win-opensource-src-4.2.2.zip and acs-4.2.2-patch1.zip to c:/qt/qt-win-opensource-src-4.2.2
| |
| http://www.paraview.org/Wiki/Obtaining_GPL'ed_Qt_for_Windows
| |
| * Edit C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\vsvars32.bat
| |
| * Add path to Platform SDK bin, include and lib:
| |
| C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Bin
| |
| C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Include
| |
| C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Lib
| |
| * Launch Cygwin.exe, and apply the following patch
| |
| patch -p1 -i qtwin_patch\msvc_bcc32_42.patch
| |
| * Launch Start > All Programs > Visual C++ Express Edition > Visual Studio Tools > Visual Studio 2005 Command Prompt
| |
| * cd ..; cd qt; cd qt-win-opensource-src-4.2.2
| |
| * Configure Qt and answer yes to all questions
| |
| qconfigure.bat msvc2005
| |
| * Configure ParaView3 using CMake; Compile using MSVC2005
| |
|
| |
|
| ===Install Qt OpenSource for Mac===
| | [[Image:TestCellIdAnimation.gif]] |
| * Build for Debug
| |
| cp -r qt-mac-opensource-4.2.2 ~/qt-4.2.2-debug
| |
| cd ~/qt-4.2.2-debug
| |
| ./configure -debug -prefix /usr/local/qt-4.2.2-debug
| |
| yes
| |
| make
| |
| sudo make install
| |

| cd ~/qt-4.2.2-release
| |
| ./configure -prefix /usr/local/qt-4.2.2-release
| |
| yes
| |
| make
| |
| sudo make install
| |
|
| |
|
| ===Change shell in Debian===
| | Close up on the texture of the streamlines. |
| * Type:
| |
| chsh
| |
| * Type your password
| |
| * Logout and login again.
| |
| * Set up the .zshrc file.
| |
|
| |
|
| ===Associate hostname with IP address for SSH===
| | [[Image:TestCellIdTubeActor1.png]] |
| * Dynamic way:
| |
| Add in /etc/dhcp3/dhclient.conf
| |
| send host-name "<your_host_name>";
| |
| * Static way: (not as good)
| |
| Add IP address and hostname in /etc/hosts (Linux) or
| |
| C:/WINDOWS/system32/drivers/etc/hosts (Cygwin):
| |
| 102.54.94.97 rhino.acme.com # source server
| |
