Full source code is included in the Tinman 3D SDK download.

Abstract base class for Direct3D 9 IRenderEffect implementations.

An implementing class must perform the following steps in its constructor:

Because there are no render state blocks / objects that could be created in the constructor, the render state for each pass must be setup by subclasses, using the following methods:

If an implementation wants to use low-level parameter slots, the following steps must be performed in the constructor:

The RS_SRGBWRITEENABLE render state is set automatically according to the RenderTargetFormat.Srgb format flags of render targets that have been set via IGraphicsContext.SetRenderTarget.

The SAMP_SRGBTEXTURE sampler state is set automatically according to ITexture.IsSrgb when a texture is set via IRenderEffectParameters.ParameterTexture1 or IRenderEffectParameters.ParameterTexture2.

Render​State​Float

public method RenderStateFloat → (2)

state in : int32

The RS_* render state to set.

value in : float32

The render state value.

Sets a render state value.

Render​State​Int

public method RenderStateInt → (2)

state in : int32

The RS_* render state to set.

value in : int32

The render state value.

Sets a render state value.

Render​State​Set

public virtual method RenderStateSet → (1)

renderState in : RenderStatePreset

The render state preset for this pass, see RenderEffectParameters.EffectRenderState.

Sets the render state for the given rendering stage.

As convenience for setting up further render state, the default implementation calls RenderStateDefault, then RenderStateApply and finally SamplerStateApply2 for all shader resources with automatic state setup (see RenderEffectParameters.EffectComponents).
