Detailed Description

An interface class to manage access to various parameters used by DirectX effects.

Description:: The Effect file has many internal presentations and as such the DxMaterial does not always store a one to one look up. Many parameters are stored in a ParamBlock and can be accessed that way.
The paramblock index for the Effect is located at 0 (the material maintains 5 ParamBlocks) and hosts all the parameters with the param name being that of the parameter in the effect File.

However not all entries in the paramblock match the parameter type of the effect file directly. One such example is the light data, which in the paramblock will use a TYPE_INTLISTBOX, where in the Effect file it is a vector.

To overcome this, the interface provides direct access to the lights and textures used by the effect. It is possible to both get and set the bitmaps, but only read access is available for the lights.

Member Function Documentation

◆ ReloadDXEffect()

virtual void ReloadDXEffect ( )

pure virtual

Reloads the current active effect.

◆ GetNumberOfEffectBitmaps()

virtual int GetNumberOfEffectBitmaps ( )

pure virtual

Returns the number of bitmaps used by the currently loaded effect.

The number of bitmaps returned will be equal to the number of bitmap entries found in the effect file. This will include bitmap slots that haven't been assigned, so it is important to check the return value from the various Bitmap related functions that take an index.

Returns: The number of bitmaps

◆ GetEffectBitmap()

virtual PBBitmap* GetEffectBitmap ( int index )

pure virtual

Gets the bitmap used by the effect.

Parameters

index The index of the bitmap to retrieve

Returns: A PBBitmap pointer for the bitmap used

◆ SetEffectBitmap()

virtual void SetEffectBitmap	(	int	index,
		PBBitmap *	bmap
	)

pure virtual

Set the bitmap used by the effect.

Parameters

index	The index of the bitmap to set
*bmap	A PBBitmap pointer for the bitmap to set

◆ GetEffectFile()

virtual const MaxSDK::AssetManagement::AssetUser& GetEffectFile ( )

pure virtual

Get the Dx Effect file AssetUser.

This can also be accessed via the paramblock, but it is simply provided for completeness

Returns: The effect file in use

◆ SetEffectFile()

virtual void SetEffectFile ( const MaxSDK::AssetManagement::AssetUser & file )

pure virtual

Set the Dx Effect file AssetUser.

This can also be accessed via the paramblock, but it is simply provided for completeness

Parameters

file	The effect file to set

◆ GetSoftwareRenderBitmap()

virtual PBBitmap* GetSoftwareRenderBitmap ( )

pure virtual

Get the bitmap used for the software rendering overrride.

This can also be set by the Paramblock, it is just used for completeness return The Bitmap used

◆ SetSoftwareRenderBitmap()

virtual void SetSoftwareRenderBitmap ( PBBitmap * bmap )

pure virtual

Set the bitmap to be used by the Renderer.

This can also be set by the Paramblock, it is just used for completeness

Parameters

*bmap A PBBitmap specifiying the bitmap to use

◆ GetNumberOfLightParams()

virtual int GetNumberOfLightParams ( )

pure virtual

Get the number of light based parameters.

This will return the number of parameters that are light based, even Light Color. Care needs to be taken with Light Color as it could also have a Color Swatch associated with it, so could already have been exported as part of the ParamBlock.

Returns: The number of light based parameters

◆ GetLightNode()

virtual INode* GetLightNode ( int index )

pure virtual

The actual node used by the parameter.

This represent the light node used by the parameter. Care needs to taken as this could be a NULL pointer. There are two reason for this. The first is that the LightColor Semantic is stored internally as a LightElement, but the writer of the Effect file may not have specified a parentID for the light, this will result in a NULL. Secondly if the user has not actually assigned a light via the UI drop down list, then again this will again result in a NULL pointer.

Parameters

index The index of the light to return.

Returns: The INode for the active light.

◆ GetLightParameterName()

virtual const MCHAR* GetLightParameterName ( int index )

pure virtual

The name of the parameter in the Effect file.

◆ GetLightSemantic()

virtual LightSemantics GetLightSemantic ( int index )

pure virtual

The light semantic as defined in the effect file.
