ID3DXEffect interface

Used to set and query effects, and to choose techniques. An effect object can contain multiple techniques to render the same effect.

Members

The ID3DXEffect interface inherits from ID3DXBaseEffect. ID3DXEffect also has these types of members:

The ID3DXEffect interface has these methods.

Method	Description
ApplyParameterBlock	Apply the values in a state block to the current effect system state.
Begin	Starts an active technique.
BeginParameterBlock	Start capturing state changes in a parameter block.
BeginPass	Begins a pass, within the active technique.
CloneEffect	Creates a copy of an effect.
CommitChanges	Propagate state changes that occur inside of an active pass to the device before rendering.
DeleteParameterBlock	Delete a parameter block.
End	Ends an active technique.
EndParameterBlock	Stop capturing effect parameter state changes.
EndPass	End an active pass.
FindNextValidTechnique	Searches for the next valid technique, starting at the technique after the specified technique.
GetCurrentTechnique	Gets the current technique.
GetDevice	Retrieves the device associated with the effect.
GetPool	Gets a pointer to the pool of shared parameters.
GetStateManager	Get the effect state manager.
IsParameterUsed	Determines if a parameter is used by the technique.
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.
OnResetDevice	Use this method to re-acquire resources and save initial state.
SetRawValue	Set a contiguous range of shader constants with a memory copy.
SetStateManager	Set the effect state manager.
SetTechnique	Sets the active technique.
ValidateTechnique	Validate a technique.

The LPD3DXEFFECT type is defined as a pointer to this interface.
