Installing OpenGLYou need to install an environment on your hardware where you can compile andrun OpenGL programs. OpenGL is supported on most modern operating systems, buthow to compile and link programs varies greatly. The description below assumesthat you already have a compilation environment set up.Before asking for help, look at theto localize the problem rather than asking a meaningless question likeIt doesn't work.LinuxOpenGL support is very easy to enable on current Linux distributions. Fordistributions derived from RedHat Linux, the libraries and header files areinstalled using the commandyum install freeglut-develSince GLUT depends on OpenGL and a number of other libraries, installing GLUTwill trigger the dependencies needed to install everything else. Fordistributions derived from Debian such as Ubuntu, the installation command isapt-get install freeglut3-devTo compile and link your program on Ubuntu based distros you need toexplicitly grab every library usinggcc -o foo foo.c -lglut -lGLU -lGL -lmI recommend that you use this full version even if not required on your system.Older distributions may put the files in /usr/X11R6, in which case you need toadd -I and -L flags to pick up the header files and libraries.Once installed, run the glxinfo program and look for direct rendering in theoutput. If the result is YES, then hardware support for OpenGL is working.
Revisa este manual paso a paso Instalar Mac OS X Leopard en un PC con Procesador Intel o AMD Post Viejo En neoteo han echo la traduccion de un articulo publicado en DailyApps donde comentan paso a paso como instalar el Mac OS Leopard (la ultima version del sistema operativo de Apple) en un PC.
Ifit is NO, some things are done in software and you may take a performance hit.Depending on your hardware, you may want to work on your X server.Specifically, the nVidia and AMD/ATI web sites contains updated drivers thatresult in improved performance over the stock Xorg drivers. On Ubuntu using theAdditional Drivers integrates the vendor drivers with the Ubuntu kernels, which isthe recommended procedure to void manual updates when the kernel is upgraded.The compiz window manager (which is an OpenGL window manager) makes applicationswhich use glutIdleFunc run jerky unless you enable VSync. This seems to be anissue especially with newer Ubuntu installs.OS/XThe OS/X Darwin environment is based on OpenGL. Therefore any compilationenvironment for OS/X should already support compiling OpenGL programs.To compile and link your program using the Apple SDK requiresgcc -o foo foo.c -framework GLUT -framework OpenGLNote that under OS/X, the GLUT header files are in the subdirectory GLUT rather thanthe GL subdirectory. The following code works on OSX and Linux#ifdef APPLE#include #else#include #endifOn recent versions of OSX, you will get many warnings indicating that GLUT isdeprecated. You can suppress these spurious warnings using the compiler flag-Wno-deprecated-declarations WindowsVarious Windows versions support OpenGL natively, but graphics cardmanufacturers often replace the native Windows OpenGL libraries with their ownlibraries that support specific features of their hardware.Since most Windows environments do not contain a native compilation suite,installing the necessary header files and libraries differs depending on thecompiler used. You may also need to install.Windows: MinGWIf you don't have a compiliation environment on Windows, the path of least resistanceis to install MinGW which provides the gcc and g compilers for Windows.Download and installAccept the default install location C:MinGW and installmingw32-base, mingw32-gcc-g and msys-base.
After theinstallation is completed, change directories to C:MinGWbin and renamemingw32-make.exe to make.exe to avoid having to type mingw32-makeevery time you want to use make. You should also add C:MinGWbin tothe beginning of your PATH.Finally, install GLUT by unzippinginto C:MinGW. It will provide includeGLglut.h andliblibglut32cu.a needed to use GLUT. It also providesbinglut32.dll.
. cmfafter some testing, I have to say that opencl support on the intel gpu is quite solid. The only thing that seems to be broken is retrieving compiled opencl program/kernel binaries (amd gpus on os x have the same issue). Performance is about 1/3 of the gt 650m. And it’s supporting host unified memory (haven’t tested it yet, but the flag is set).also supported by both the intel and the nvidia gpu.drumroll.: printf ?unsupported by both: device partitioning and built-in kernels (does anybody support this?)apparently as an alternative to device partitioning, apple has added a new extension called “clAPPLEcommandqueueselectcomputeunits”.info from clext.h:/. Extension: clCreateCommandQueueWithPropertiesAPPLE. Create a command queue for the specified device.
The properties array. specifies a list of command queue property names and their corresponding. values.
Each property name is immediately followed by the corresponding. value.
The list is terminated with 0. List of supported properties are:. CLQUEUEPROPERTIES clcommandqueueproperties bitfield.
( CLQUEUEPROFILINGENABLE,. CLQUEUEOUTOFORDEREXECMODEENABLE). CLCOMMANDQUEUEPRIORITYAPPLE clqueuepropertiesAPPLE. ( CLCOMMANDQUEUEPRIORITYDEFAULTAPPLE,.
CLCOMMANDQUEUEPRIORITYBACKGROUNDAPPLE ). These properties may only be used if the clAPPLEcommandqueuepriority is. supported by the device. CLCOMMANDQUEUENUMCOMPUTEUNITSAPPLE int (value can be 1. CLDEVICEMAXCOMPUTEUNITS). This property may only be used if the.
clAPPLEcommandqueueselectcomputeunits extension is supported by the. device./.
