Begin(GorgonBlendState, GorgonDepthStencilState, GorgonRasterState, GorgonCameraCommon)

Function to begin rendering the effect.

Declaration
public void Begin(GorgonBlendState blendState = null, GorgonDepthStencilState depthStencilState = null, GorgonRasterState rasterState = null, GorgonCameraCommon camera = null)
Parameters
Type Name Description
GorgonBlendState blendState

[Optional] A user defined blend state to apply when rendering.
GorgonDepthStencilState depthStencilState

[Optional] A user defined depth/stencil state to apply when rendering.
GorgonRasterState rasterState

[Optional] A user defined rasterizer state to apply when rendering.
GorgonCameraCommon camera

[Optional] The camera to use when rendering.

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

OnBeforeRender(GorgonRenderTargetView, bool)

Function called prior to rendering.

Declaration
protected override void OnBeforeRender(GorgonRenderTargetView output, bool sizeChanged)
Parameters
Type Name Description
GorgonRenderTargetView output

The final render target that will receive the rendering from the effect.
bool sizeChanged

true if the output size changed since the last render, or false if it's the same.
Overrides
Remarks

Applications can use this to set up common states and other configuration settings prior to executing the render passes. This is an ideal method to initialize and resize your internal render targets (if applicable).

OnGetBatchState(int, IGorgon2DEffectBuilders, bool)

Function called to build a new (or return an existing) 2D batch state.

Declaration
protected override Gorgon2DBatchState OnGetBatchState(int passIndex, IGorgon2DEffectBuilders builders, bool statesChanged)
Parameters
Type Name Description
int passIndex

The index of the current rendering pass.
IGorgon2DEffectBuilders builders

The builder types that will manage the state of the effect.
bool statesChanged

true if the blend, raster, or depth/stencil state was changed. false if not.
Returns
Type Description
Gorgon2DBatchState

The 2D batch state.
Overrides

OnInitialize()

Function called when the effect is being initialized.

Declaration
protected override void OnInitialize()
Overrides
Remarks

Use this method to set up the effect upon its creation. For example, this method could be used to create the required shaders for the effect.

When creating a custom effect, use this method to initialize the effect. Do not put initialization code in the effect constructor.

Render(GorgonTexture2DView, GorgonRenderTargetView)

Function to render an effect under the Gorgon2DCompositor.

Declaration

Parameters
Type Name Description
GorgonTexture2DView texture
