PrtBuffer Class (Microsoft.DirectX.Direct3D)

Used as a data buffer to store vertex and pixel data for use with precomputed radiance transfer (PRT) methods and functions.

Members Table

The following table lists the members exposed by the object.

Events

Event	Description
Disposing	Occurs when the Dispose method is called or when the PrtBuffer object is finalized and collected by the garbage collector of the .NET common language runtime.

Methods

Method	Description
AddBuffer	Adds another buffer to the PrtBuffer and stores the results in PrtBuffer.
AttachGutterHelper	Associates a TextureGutterHelper object with the PrtBuffer object.
Dispose	Immediately releases the unmanaged resources used by the PrtBuffer object.
Equals	Returns a value that indicates whether the current instance is equal to a specified object.
EvaluateGutterHelper	Applies stored texture gutter data to a PrtBuffer texture buffer.
ExtractTexture	Extracts coefficient data from a color channel of the buffer for a specified range of coefficients, and adds the data to a Texture object.
ExtractToMesh	Extracts coefficient data from a single-channel buffer and adds the data to a Mesh object.
Finalize	Allows the PrtBuffer object to free resources before it is destroyed by the garbage collector.
FromFile	Loads into memory a PRT buffer that was saved to disk.
GetHashCode	Returns the hash code for the current instance.
GetObjectByValue	This member supports the infrastructure for Microsoft DirectX 9.0 for Managed Code and is not intended to be used directly from your code.
LockBuffer	Locks a range of vertex or texel sample data and returns a GraphicsStream object containing the locked buffer memory.
LockBufferSingleArray	Locks a range of vertex or texel sample data and returns an array containing the locked buffer memory.
op_Equality	Compares the current instance of a class to another instance to determine whether they are the same.
op_Inequality	Compares the current instance of a class to another instance to determine whether they are different.
PrtBuffer	Initializes a new instance of the PrtBuffer class.
raise_Disposing	Raises the Microsoft.DirectX.Direct3D.PrtBuffer.Disposing event when called from within a derived class.
ReleaseGutterHelper	Disassociates an attached TextureGutterHelper object with the PrtBuffer object.
Resize	Changes the number of samples contained in the buffer.
Save	Saves a PRT buffer to disk.
ScaleBuffer	Multiplies every value in the buffer by a constant value.
UnlockBuffer	Unlocks the buffer locked by PrtBuffer.LockBuffer or PrtBuffer.LockBufferSingleArray.
UpdateUnmanagedPointer	Updates the unmanaged pointer for this PrtBuffer object. This method supports the Microsoft .NET Framework infrastructure and is not intended to be used directly in your code.

Properties

Property	Description
Disposed	Gets a value that indicates whether the object is disposed.
Height	Retrieves the height of the texture, in pixels.
IsTexture	Indicates whether the buffer contains a texture.
NumberChannels	Retrieves the number of color channels used in memory to store samples.
NumberCoefficients	Retrieves the number of scalars per color channel used in memory to store samples.
NumberSamples	Retrieves the number of vertices (or texels) sampled.
UnmanagedComPointer	Returns the unmanaged Component Object Model (COM) ID3DXPRTBuffer interface pointer.
Width	Retrieves the width of the texture, in pixels.
