Creating and Initializing a Graphics Device

Creating a default device

#include <Factory.h>
 
{
    // Create a graphics device with the default type.
    auto device = Cogs::Factory::createDevice();
 
    if (!device) {
        // Error creating a device of the default type.
    }
    
    ...
}

Creating a device of a specific type

Since the rendering abstraction library might be built with support for multiple graphics device types it might be necessary to specify the desired type.

Valid types are:

• OpenGL20
• OpenGLES30
• Direct3D11

#include <Factory.h>
 
{
    // Create an OpenGL20 graphics device.
    auto device = Cogs::Factory::createDevice(Cogs::GraphicsDeviceType::OpenGL20);
 
    if (!device) {
        // Error creating a device of the given type.
    }
    
    ...
}

Initializing the graphics device

When you have created a valid graphics device it can be initialized in the current application context.

Initializing a graphics device on Windows systems:

#include <Factory.h>
 
{
    ...
    
    if (!device->initialize(hWnd)) {
        // Error initializing the device.
    }
 
    ...
}
