| === 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== |

| ===Build VTK with Offscreen Rendering on Linux===
| |
| OSMesa (Off Screen Mesa) is a library that does rendering and does not need a graphics context.
| |
| You can use it on a server that does not have a graphics card or any graphics capability.
| |
| To use VTK with OffScreen Rendering on Linux, you need to compile VTK with the OSMesa option on.
| |
| Configure VTK using CMake.
| |
| Hit 't' for Advanced Options
| |
| Turn VTK_OPENGL_HAS_OSMESA ON
| |
| Hit 'c' to configure again.
| |
| Set path to include dir and library:
| |
| OSMESA_INCLUDE_DIR
| |
| OSMESA_LIBRARY
| |
| Turn VTK_USE_OFFSCREEN ON if you want offscreen by default.
| |
| | |
| If you built Mesa from source and link to it, your dependencies should be ok.
| |
| If you installed the OSMesa packages for Debian and did not build VTK from scratch,
| |
| your dependencies might be messed up.
| |
| Then once you have configured your CMakeLists.txt,
| |
| check that this CMakeLists.txt variable is set to zero, and then type make:
| |
| VTK_USE_GLX_GET_PROC_ADDRESS_ARB:INTERNAL=0
| |
| | |
| On Debian, I installed:
| |
| libosmesa6
| |
| libosmesa6-dev
| |
| | |
| To check if Mesa was installed correctly, you can type in a terminal:
| |
| | |
| $ glxinfo | grep renderer
| |
| OpenGL renderer string: Mesa X11
| |
| | |
| It should return the line above.
| |
| In case you get the Nvidia drivers for example, then Mesa was not installed correctly.
| |
| To get info about OpenGL libraries used by a VTK 6.0 build, you can use the test LoadOpenGLExtensions.
| |
| | |
| When you run your VTK code with Mesa, you can turn offscreen rendering on in your application:
| |
| RenderWindow->OffScreenRenderingOn();
| |
| and no render window will pop up.
| |
| | |
| To generate screenshots, use:
| |
| vtkWindowToImageFilter.
| |
| | |
| ==Install Nvidia drivers for Debian==
| |
| Download Linux Nvidia drivers from www.nvidia.com
| |
| to your home dir.
| |
| apt-get install gcc
| |
| apt-get install libc
| |
| CTRL-ALT-F1
| |
| login: root
| |
| killall gdm
| |
| /home/sylvain/NVIDIA-...
