Used to set and query effects, and to choose techniques. An effect object can contain multiple techniques to render the same effect.
| Method | Description |
|---|---|
| ID3DXEffect::ApplyParameterBlock | Apply the values in a state block to the current effect system state. |
| ID3DXEffect::Begin | Starts an active technique. |
| ID3DXEffect::BeginParameterBlock | Start capturing state changes in a parameter block. |
| ID3DXEffect::BeginPass | Begins a pass, within the active technique. |
| ID3DXEffect::CloneEffect | Creates a copy of an effect. |
| ID3DXEffect::CommitChanges | Propagate state changes that occur inside of an active pass to the device before rendering. |
| ID3DXEffect::DeleteParameterBlock | Delete a parameter block. |
| ID3DXEffect::End | Ends an active technique. |
| ID3DXEffect::EndParameterBlock | Stop capturing effect parameter state changes. |
| ID3DXEffect::EndPass | End an active pass. |
| ID3DXEffect::FindNextValidTechnique | Searches for the next valid technique, starting at the technique after the specified technique. |
| ID3DXEffect::GetCurrentTechnique | Gets the current technique. |
| ID3DXEffect::GetDevice | Retrieves the device associated with the effect. |
| ID3DXEffect::GetPool | Gets a pointer to the pool of shared parameters. |
| ID3DXEffect::GetStateManager | Get the effect state manager. |
| ID3DXEffect::IsParameterUsed | Determines if a parameter is used by the technique. |
| ID3DXEffect::OnLostDevice | Use this method to release all references to video memory resources and delete all stateblocks. This method should be called whenever a device is lost, or before resetting a device. |
| ID3DXEffect::OnResetDevice | Use this method to re-acquire resources and save initial state. |
| ID3DXEffect::SetRawValue | Set a contiguous range of shader constants with a memory copy. |
| ID3DXEffect::SetStateManager | Set the effect state manager. |
| ID3DXEffect::SetTechnique | Sets the active technique. |
| ID3DXEffect::ValidateTechnique | Validate a technique. |
The ID3DXEffect interface is obtained by calling D3DXCreateEffect, D3DXCreateEffectFromFile, or D3DXCreateEffectFromResource.
The LPD3DXEFFECT type is defined as a pointer to this interface.
