Class TunnelBlock

Namespace
VisioForge.Core.MediaBlocks.VideoProcessing
Assembly
VisioForge.Core.dll

Video tunnel effect block that creates a perspective tunnel or vortex visual effect. This block applies a tunnel transformation that warps the video into a perspective tunnel, creating the illusion of depth and movement through a cylindrical or spiral passageway. Features include depth control, rotation effects, center positioning, and perspective adjustments. Essential for music videos, sci-fi transitions, hypnotic visual effects, and creative content requiring tunnel vision or vortex-like transformations. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Methods

Build()

Constructs and initializes the tunnel filter and its associated GStreamer elements. This method creates the filter, establishes input and output pads, and prepares the block for applying perspective tunnel or vortex effects to video content.

public override bool Build()

Returns

bool

true if the filter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this tunnel effect block. This method disposes of the GStreamer elements and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed 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 BaseElement wrapper that provides additional functionality around the GStreamer tunnel filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer tunnel filter.

GetElement()

Gets the underlying GStreamer element that performs the tunnel transformation.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the tunnel filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project.

public static bool IsAvailable()

Returns

bool

true if this media block is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this tunnel effect block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
