Member Data Documentation

◆ AntiAlias

u8 jpp::SJimcppCreationParameters::AntiAlias

Specifies if the device should use fullscreen anti aliasing.

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

◆ DeviceType

E_DEVICE_TYPE jpp::SJimcppCreationParameters::DeviceType

Type of the device.

This setting decides the windowing system used by the device, most device types are native to a specific operating system and so may not be available. EIDT_WIN32 is only available on Windows desktops, EIDT_WINCE is only available on Windows mobile devices, EIDT_COCOA is only available on Mac OSX, EIDT_X11 is available on Linux, Solaris, BSD and other operating systems which use X11, EIDT_SFML is available on most systems if compiled in, EIDT_CONSOLE is usually available but can only render to text, EIDT_BEST will select the best available device for your operating system. Default: EIDT_BEST.

◆ DisplayAdapter

u32 jpp::SJimcppCreationParameters::DisplayAdapter

Allows to select which graphic card is used for rendering when more than one card is in the system.

So far only supported on D3D

◆ Doublebuffer

bool jpp::SJimcppCreationParameters::Doublebuffer

Whether the main framebuffer uses doublebuffering.

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

◆ DriverMultithreaded

bool jpp::SJimcppCreationParameters::DriverMultithreaded

Create the driver multithreaded.

Default is false. Enabling this can slow down your application. Note that this does not make Jimcpp threadsafe, but only the underlying driver-API for the graphiccard. So far only supported on D3D.

◆ DriverType

video::E_DRIVER_TYPE jpp::SJimcppCreationParameters::DriverType

Type of video driver used to render graphics.

This can currently be video::EDT_NULL, video::EDT_SOFTWARE, video::EDT_BURNINGSVIDEO, video::EDT_DIRECT3D9, and video::EDT_OPENGL. Default: EDT_BURNINGSVIDEO.

◆ Fullscreen

bool jpp::SJimcppCreationParameters::Fullscreen

Should be set to true if the device should run in fullscreen.

Otherwise the device runs in windowed mode. Default: false.

◆ HandleSRGB

bool jpp::SJimcppCreationParameters::HandleSRGB

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.

◆ HighPrecisionFPU

bool jpp::SJimcppCreationParameters::HighPrecisionFPU

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

◆ IgnoreInput

bool jpp::SJimcppCreationParameters::IgnoreInput

Specifies if the device should ignore input events.

This is only relevant when using external I/O handlers. External windows need to take care of this themselves. Currently only supported by X11. Default value: false

◆ LoggingLevel

ELOG_LEVEL jpp::SJimcppCreationParameters::LoggingLevel

Specifies the logging level used in the logging interface.

The default value is ELL_INFORMATION. You can access the ILogger interface later on from the JimcppDevice with getLogger() and set another level. But if you need more or less logging information already from device creation, then you have to change it here.

◆ SDK_version_do_not_use

const c8* const jpp::SJimcppCreationParameters::SDK_version_do_not_use

Don't use or change this parameter.

Always set it to JIMCPP_SDK_VERSION, which is done by default. This is needed for sdk version checks.

◆ Stencilbuffer

bool jpp::SJimcppCreationParameters::Stencilbuffer

Specifies if the stencil buffer should be enabled.

Set this to true, if you want the engine be able to draw stencil buffer shadows. Note that not all drivers are able to use the stencil buffer, hence it can be ignored during device creation. Without the stencil buffer no shadows will be drawn. Default: true.

◆ Stereobuffer

bool jpp::SJimcppCreationParameters::Stereobuffer

Specifies if the device should use stereo buffers.

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. Currently only supported by OpenGL. Default value: false

◆ UsePerformanceTimer

bool jpp::SJimcppCreationParameters::UsePerformanceTimer

Enables use of high performance timers on Windows platform.

When performance timers are not used, standard GetTickCount() is used instead which usually has worse resolution, but also less problems with speed stepping and other techniques.

◆ Vsync

bool jpp::SJimcppCreationParameters::Vsync

Specifies vertical synchronization.

If set to true, the driver will wait for the vertical retrace period, otherwise not. May be silently ignored. Default: false

◆ WindowId

void* jpp::SJimcppCreationParameters::WindowId

Window Id.

If this is set to a value other than 0, the Jimcpp 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 Jimcpp run inside the custom window, you still will have to draw Jimcpp on your own. You can use this loop, as usual:

while (device->run())
{
    driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
    smgr->drawAll();
    driver->endScene();
}

Instead of this, you can also simply use your own message loop using GetMessage, DispatchMessage and whatever. Calling JimcppDevice::run() will cause Jimcpp to dispatch messages internally too. You need not call Device->run() if you want to do your own message dispatching loop, but Jimcpp 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 Jimcpp timer. An alternative, own message dispatching loop without device->run() would look like this:

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();
}

However, there is no need to draw the picture this often. Just do it how you like.

◆ WindowResizable

u8 jpp::SJimcppCreationParameters::WindowResizable

Should a non-fullscreen window be resizable.

Might not be supported by all devices. Ignored when Fullscreen is true. Values: 0 = not resizable, 1 = resizable, 2 = system decides default itself Default: 2

◆ WithAlphaChannel

bool jpp::SJimcppCreationParameters::WithAlphaChannel

Whether the main framebuffer uses an alpha channel.

In some situations it might be desirable to get a color buffer with an alpha channel, e.g. when rendering into a transparent window or overlay. If this flag is set the device tries to create a framebuffer with alpha channel. If this flag is set, only color buffers with alpha channel are considered. Otherwise, it depends on the actual hardware if the colorbuffer has an alpha channel or not. Default value: false
