CoreGraphics::RenderDevice Class Reference
#include <renderdevice.h>
Detailed Description
The central rendering object of the Nebula3 core graphics system. This is basically an encapsulation of the Direct3D device. The render device will presents its backbuffer to the display managed by the CoreGraphics::DisplayDevice singleton.(C) 2006 Radon Labs GmbH

Member Function Documentation
| bool Direct3D9::D3D9RenderDevice::CanCreate | ( | ) | [static, inherited] |
test if a compatible render device can be created on this machine
Test if the right Direct3D version is installed by trying to open Direct3D.
Reimplemented from Base::RenderDeviceBase.
| IDirect3D9 * Direct3D9::D3D9RenderDevice::GetDirect3D | ( | ) | [static, inherited] |
get pointer to Direct3D interface, opens Direct3D if not happened yet
Get a pointer to the Direct3D interface. Opens Direct3D if not happened yet.
| IDirect3DDevice9 * Direct3D9::D3D9RenderDevice::GetDirect3DDevice | ( | ) | const [inherited] |
get pointer to the d3d device
Return a pointer to d3d device. Asserts that the device exists.
| bool Direct3D9::D3D9RenderDevice::Open | ( | ) | [inherited] |
open the device
Open the render device. When successful, the RenderEvent::DeviceOpen will be sent to all registered event handlers after the Direct3D device has been opened.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::Close | ( | ) | [inherited] |
close the device
Close the render device. The RenderEvent::DeviceClose will be sent to all registered event handlers.
Reimplemented from Base::RenderDeviceBase.
| bool Direct3D9::D3D9RenderDevice::BeginFrame | ( | ) | [inherited] |
begin complete frame
Begin a complete frame. Call this once per frame before any rendering happens. If rendering is not possible for some reason (e.g. a lost device) the method will return false. This method may also send the DeviceLost and DeviceRestored RenderEvents to attached event handlers.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::SetVertexBuffer | ( | const Ptr< CoreGraphics::VertexBuffer > & | vb | ) | [inherited] |
set current vertex buffer
Sets the vertex buffer to use for the next Draw().
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::SetIndexBuffer | ( | const Ptr< CoreGraphics::IndexBuffer > & | ib | ) | [inherited] |
set current index buffer
Sets the index buffer to use for the next Draw().
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::Draw | ( | ) | [inherited] |
draw current primitives
Draw the current primitive group. Requires a vertex buffer, an optional index buffer and a primitive group to be set through the respective methods. To use non-indexed rendering, set the number of indices in the primitive group to 0.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::EndPass | ( | ) | [inherited] |
end current pass
End the current rendering pass. This will flush all texture stages in order to keep the d3d9 resource reference consistent without too much hassle.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::EndFrame | ( | ) | [inherited] |
end complete frame
End a complete frame. Call this once per frame after rendering and presentation has happened, and only if BeginFrame() returns true.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::Present | ( | ) | [inherited] |
present the rendered scene
NOTE: Present() should be called as late as possible after EndFrame() to improve parallelism between the GPU and the CPU.
Reimplemented from Base::RenderDeviceBase.
| void Direct3D9::D3D9RenderDevice::SaveScreenshot | ( | CoreGraphics::ImageFileFormat::Code | fmt, | |
| const Ptr< IO::Stream > & | outStream | |||
| ) | [inherited] |
save a screenshot to the provided stream
Save the backbuffer to the provided stream.
Reimplemented from Base::RenderDeviceBase.
| void Base::RenderDeviceBase::AttachEventHandler | ( | const Ptr< CoreGraphics::RenderEventHandler > & | h | ) | [inherited] |
attach a render event handler
Attach an event handler to the render device.
| void Base::RenderDeviceBase::RemoveEventHandler | ( | const Ptr< CoreGraphics::RenderEventHandler > & | h | ) | [inherited] |
remove a render event handler
Remove an event handler from the display device.
| bool Base::RenderDeviceBase::NotifyEventHandlers | ( | const CoreGraphics::RenderEvent & | e | ) | [protected, inherited] |
notify event handlers about an event
Notify all event handlers about an event.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |
get the current refcount
Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one
Increment the refcount of the object.
| void Core::RefCounted::Release | ( | ) | [inline, inherited] |
decrement refcount and destroy object if refcount is zero
Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |
get the class FourCC code
Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)
This method should be called as the very last before an application exits.
