Methods

CreateDeviceInternal()

Initialize the graphics context to be used in a compute shader.

Declaration
public override void CreateDeviceInternal()
Overrides

CreateSwapChain(SwapChainDescription)

Initialize the swapchain.

Declaration
public override SwapChain CreateSwapChain(SwapChainDescription description)
Parameters
Type Name Description
SwapChainDescription description

The swapchain descriptor.
Returns
Type Description
SwapChain

Created Swapchain.
Overrides

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

Declaration
protected override void Dispose(bool disposing)
Parameters
Type Name Description
bool disposing

true to release both managed and unmanaged resources; false to release only unmanaged resources.
Overrides

GenerateTextureMipmapping(Texture)

Generate mipmapping texture levels.

Declaration
public override bool GenerateTextureMipmapping(Texture texture)
Parameters
Type Name Description
Texture texture

The texture to generate mipmapping.
Returns
Type Description
bool

True if the mipmapping has been generated.
Overrides

InternalUpdateBufferData(Buffer, IntPtr, uint, uint)

Fill the buffer from a pointer.

Declaration
protected override void InternalUpdateBufferData(Buffer buffer, IntPtr source, uint sourceSizeInBytes, uint destinationOffsetInBytes = 0)
Parameters
Type Name Description
Buffer buffer

Buffer instance.
IntPtr source

The data pointer.
uint sourceSizeInBytes
