Class GLHeatBlock

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

OpenGL-accelerated heat shimmer effect block for creating thermal distortion and atmospheric heat wave effects. Simulates the visual distortion seen when looking through hot air, such as heat rising from pavement or fire, creating dynamic wavering and shimmering effects that add realism to hot environments and thermal scenarios. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

GLHeatBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenGL.GLHeatBlock class for heat shimmer and thermal distortion effects. Creates the necessary input and output pads for video processing with atmospheric heat wave simulation.

public GLHeatBlock()

Properties

Input

Gets the primary input pad for receiving video frames to be distorted with heat effects.

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 heat-distorted 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 heat effects.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the OpenGL heat effect block within the pipeline context. Creates the GStreamer heat filter and establishes the necessary pad connections for processing video frames with thermal shimmer and atmospheric distortion effects.

public override bool Build()

Returns

bool

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

CleanUp()

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

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the OpenGL heat effect block. Properly disposes of GStreamer elements and GPU distortion 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 heat effect filter.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The native Gst.Element representing the heat distortion effect filter.

IsAvailable()

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

public static bool IsAvailable()

Returns

bool

true if heat distortion effects are supported; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this OpenGL heat 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 heat effect block.
