Member Function Documentation

◆ activateCapabilities()

bool activateCapabilities ( WSGLRenderer & renderer )

◆ addCapability()

bool addCapability ( WSGLShaderProgramCapability * capability )

Adds a capability to the program. When the program is activated, deactivated or an item is rendered, this capability will be included in this process.

Note: Capabilitys can depend on other capabilities. This function will return false if a capability's dependencies have not already been added.

◆ bindTextureCoordBuffer()

bool bindTextureCoordBuffer	(	int	location,
		WSGLRenderer &	renderer,
		Texturizer &	texturizer,
		WSGLRenderItem &	renderItem,
		Shader &	shader
	)

Parameters

location	The vertex attribute location to which the buffer will be bound.
renderer	The renderer to which the buffer will be bound.
texturizer	The texturizer which contains details of how to get texture coordinates.
renderItem	The render item for which the coordinates are being generated.
shader	The shader being used to bind the coord buffer

Looks up (or creates) a texture coordinate buffer using the details provided by texturizer, the model referenced by renderItem and binds it to the vertex attribute location specified by location.

Returns: true if the buffer was able to be bound successfully, false otherwise.

◆ clearInternalLog()

void clearInternalLog ( )

◆ compileAndLink() [1/2]

bool compileAndLink	(	const QString &	vertexShaderFileName,
		const QString &	fragmentShaderFileName,
		const QString &	geometryShaderFileName,
		const QVariantMap &	preprocessorDefinitions = `QVariantMap()`
	)

◆ compileAndLink() [2/2]

bool compileAndLink	(	const QString &	vertexShaderFileName,
		const QString &	fragmentShaderFileName,
		const QVariantMap &	preprocessorDefinitions = `QVariantMap()`
	)

◆ deactivateCapabilities()

bool deactivateCapabilities ( WSGLRenderer & renderer )

◆ getInternalLog()

const QString & getInternalLog ( const Application::LogManager::MessageCategory & category ) const

Parameters

category The desired message category.

Returns: The message log contents for the specific category.

◆ getUseInternalLog()

bool getUseInternalLog ( ) const

◆ isValid()

bool isValid ( )

Checks whether or not the program is valid and ready to execute (see glValidateProgram). It also takes into account whether or not all of the required uniforms have been set. It will also print any validation problems (if they exist) to the log.

NOTE: Since this is invoking a series of 'get' calls, it is recommended it be used only during debug builds.

Returns: true if the program is ready to execute.

◆ renderGlyphs()

bool renderGlyphs	(	WSGLRenderer &	renderer,
		WSGLRenderItem &	item,
		RenderGlyphCallback *	perGlyphCallback = `nullptr`,
		const WSGLRenderElementsFilter *	elementFilter = `nullptr`
	)

◆ renderItem()

bool renderItem	(	WSGLRenderer &	renderer,
		WSGLRenderItem &	item,
		const WSGLRenderElementsFilter *	elementFilter = `nullptr`
	)

◆ renderUsingCustomFunction()

bool renderUsingCustomFunction	(	WSGLRenderer &	renderer,
		WSGLRenderItem &	item,
		CustomRenderFunction &	function
	)

◆ setUniformValue() [1/2]

void setUniformValue	(	int	location,
		const Mesh::TransformMatrix &	value
	)

◆ setUniformValue() [2/2]

void setUniformValue	(	int	location,
		const Mesh::Vector3d &	value
	)

◆ setUseInternalLog()

void setUseInternalLog ( bool b )
