Class GLLightTunnelBlock

Namespace
VisioForge.Core.MediaBlocks.OpenGL
Assembly
VisioForge.Core.dll

OpenGL-accelerated light tunnel effect block for creating dramatic radial lighting and tunnel vision effects. Generates dynamic tunnel-like light patterns that draw the viewer's attention to the center of the frame, creating cinematic depth effects and dramatic visual focus with customizable radial light distribution. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

GLLightTunnelBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenGL.GLLightTunnelBlock class for radial light tunnel effects. Creates the necessary input and output pads for video processing with dramatic tunnel lighting and visual focus.

public GLLightTunnelBlock()

Properties

Input

Gets the primary input pad for receiving video frames to be enhanced with tunnel lighting.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads available on this block (single input for video processing).

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the primary output pad for providing light tunnel enhanced video frames.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads available on this block (single output for processed video).

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Type

Gets the media block type identifier for OpenGL light tunnel effects.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the OpenGL light tunnel effect block within the pipeline context. Creates the GStreamer light tunnel filter and establishes the necessary pad connections for processing video frames with radial lighting and tunnel vision effects.

public override bool Build()

Returns

bool

true if the light tunnel effect block was successfully built and configured; otherwise, false.

CleanUp()

Cleans up all resources associated with the OpenGL light tunnel effect, including GStreamer elements and GPU shader programs.

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the OpenGL light tunnel effect block. Properly disposes of GStreamer elements and GPU lighting shader resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core GStreamer element wrapper for advanced configuration and monitoring.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper providing access to the underlying GStreamer light tunnel filter.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The native Gst.Element representing the light tunnel effect filter.

IsAvailable()

Determines whether OpenGL light tunnel effect functionality is available on the current system. Requires OpenGL support and appropriate GStreamer OpenGL lighting effect plugins to be installed.

public static bool IsAvailable()

Returns

bool

true if light tunnel effects are supported; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this OpenGL light tunnel effect block, providing access to the parent pipeline and logging context.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline containing this light tunnel effect block.
