Effect System Interfaces (Direct3D 11)
The effect system defines several interfaces for managing effect state. There are two types of interfaces: those used by the runtime to render an effect and reflection interfaces for getting and setting effect variables.
Effect Runtime Interfaces
Use runtime interfaces to render an effect.
| Runtime Interfaces | Description |
|---|---|
| ID3DX11Effect | Collection of one or more groups and techniques for rendering. |
| ID3DX11EffectPass | A collection of state assignments. |
| ID3DX11EffectTechnique | A collection of one or more passes. |
| ID3DX11EffectGroup | A collection of one or more techniques. |
Effect Reflection Interfaces
Reflection is implemented in the effect system to support reading (and writing) effect state. There are multiple ways to access effect variables.
Setting Groups of Effect State
Use these interfaces to get and set a group of state.
| Reflection Interfaces | Description |
|---|---|
| ID3DX11EffectBlendVariable | Get and set blend state. |
| ID3DX11EffectDepthStencilVariable | Get and set depth-stencil state. |
| ID3DX11EffectRasterizerVariable | Get and set rasterizer state. |
| ID3DX11EffectSamplerVariable | Get and set sampler state. |
Setting Effect Resources
Use these interfaces to get and set resources.
| Reflection Interfaces | Description |
|---|---|
| ID3DX11EffectConstantBuffer | Access data in a texture buffer or constant buffer. |
| ID3DX11EffectDepthStencilViewVariable | Access data in a depth-stencil resource. |
| ID3DX11EffectRenderTargetViewVariable | Access data in a render target. |
| ID3DX11EffectShaderResourceVariable | Access data in a shader resource. |
| ID3DX11EffectUnorderedAccessViewVariable | Access data in an unordered access view. |
Setting Other Effect Variables
Use these interfaces to get and set state by the variable type.
| Reflection Interfaces | Description |
|---|---|
| ID3DX11EffectClassInstanceVariable | Get a class instance. |
| ID3DX11EffectInterfaceVariable | Get and set an interface. |
| ID3DX11EffectMatrixVariable | Get and set a matrix. |
| ID3DX11EffectScalarVariable | Get and set a scalar. |
| ID3DX11EffectShaderVariable | Get a shader variable. |
| ID3DX11EffectStringVariable | Get and set a string. |
| ID3DX11EffectType | Get a variable type. |
| ID3DX11EffectVectorVariable | Get and set a vector. |
All reflection interfaces derive from ID3DX11EffectVariable.
