Detailed Description

Texture node for displaying the render texture from gz-renderer.

Constructor & Destructor Documentation

TextureNode()

TextureNode ( QQuickWindow *  _window, RenderSync &  _renderSync, const rendering::GraphicsAPI &  _graphicsAPI  )

explicit

Constructor.

Parameters

[in]	_window	Window to display the texture
[in]	_renderSync	RenderSync to safely synchronize Qt (this) and worker thread
[in]	_graphicsAPI	The type of graphics API

~TextureNode()

~TextureNode ( )

override

Destructor.

Member Function Documentation

NewTexture

void NewTexture ( void *  _texturePtr, const QSize &  _size  )

slot

This function gets called on the FBO rendering thread and will store the texture id and size and schedule an update on the window.

Parameters

[in]	_texturePtr	Pointer to a texture Id
[in]	_size	Texture size

PendingNewTexture

void PendingNewTexture ( )

signal

Signal emitted when a new texture is ready to trigger window update.

PrepareNode

void PrepareNode ( )

slot

Before the scene graph starts to render, we update to the pending texture.

TextureInUse

void TextureInUse ( RenderSync *  _renderSync )

signal

Parameters

[in]

_renderSync

RenderSync to send to the worker thread

Member Data Documentation

mutex

QMutex mutex

Mutex to protect the texture variables.

renderSync

RenderSync& renderSync

See RenderSync.

size

QSize size = QSize(0, 0)

Texture size.

window

QQuickWindow* window = nullptr

Qt quick window.
