EIDT_COCOA is only available on Mac OSX,

use the stencil buffer, hence it can be ignored during device
creation. Without the stencil buffer no shadows will be drawn.

/** Makes sharp/pixelated edges softer, but requires more
performance. Also, 2D elements might look blurred with this
switched on. The resulting rendering quality also depends on
the hardware and driver you are using, your program might look
different on different hardware with this. So if you are
writing a game/application with AntiAlias switched on, it would
be a good idea to make it possible to switch this option off
again by the user.
The value is the maximal antialiasing factor requested for
the device. The creation method will automatically try smaller
values if no window can be created with the given value.
Value one is usually the same as 0 (disabled), but might be a
special value on some platforms. On D3D devices it maps to
NONMASKABLE.
Default value: 0 - disabled */

//! Flag to enable proper sRGB and linear color handling
/** In most situations, it is desirable to have the color handling in
non-linear sRGB color space, and only do the intermediate color
calculations in linear RGB space. If this flag is enabled, the device and
driver try to assure that all color input and output are color corrected
and only the internal color representation is linear. This means, that
the color output is properly gamma-adjusted to provide the brighter
colors for monitor display. And that blending and lighting give a more
natural look, due to proper conversion from non-linear colors into linear
color space for blend operations. If this flag is enabled, all texture colors
(which are usually in sRGB space) are correctly displayed. However vertex colors
and other explicitly set values have to be manually encoded in linear color space.
Default value: false. */

/** In some situations it might be desirable to get a color
buffer with an alpha channel, e.g. when rendering into a

are considered. Otherwise, it depends on the actual hardware
if the colorbuffer has an alpha channel or not.

/** This should be usually enabled, in order to avoid render
artifacts on the visible framebuffer. However, it might be
useful to use only one buffer on very small devices. If no
doublebuffering is available, the drivers will fall back to
single buffers. Default value: true */

/** Some high-end gfx cards support two framebuffers for direct
support of stereoscopic output devices. If this flag is set the
device tries to create a stereo context.

Default value: false */
bool Stereobuffer;
//! Specifies if the device should use high precision FPU setting
/** This is only relevant for DirectX Devices, which switch to
low FPU precision by default for performance reasons. However,
this may lead to problems with the other computations of the
application. In this case setting this flag to true should help
- on the expense of performance loss, though.
Default value: false */

//! A user created event receiver.
IEventReceiver* EventReceiver;
//! Window Id.
/** If this is set to a value other than 0, the Irrlicht Engine
will be created in an already existing window. For windows, set
this to the HWND of the window you want. The windowSize and
FullScreen options will be ignored when using the WindowId
parameter. Default this is set to 0.
To make Irrlicht run inside the custom window, you still will
have to draw Irrlicht on your own. You can use this loop, as
usual:
\code
while (device->run())
{
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode
Instead of this, you can also simply use your own message loop
using GetMessage, DispatchMessage and whatever. Calling
IrrlichtDevice::run() will cause Irrlicht to dispatch messages
internally too. You need not call Device->run() if you want to
do your own message dispatching loop, but Irrlicht will not be
able to fetch user input then and you have to do it on your own
using the window messages, DirectInput, or whatever. Also,
you'll have to increment the Irrlicht timer.
An alternative, own message dispatching loop without
device->run() would look like this:
\code
MSG msg;
while (true)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
if (msg.message == WM_QUIT)
break;
}
// increase virtual timer time
device->getTimer()->tick();
// draw engine picture
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode
However, there is no need to draw the picture this often. Just
do it how you like. */
