Member Function Documentation

initialize()

void initialize

(

)

Initialize the OpenGL context for rendering.

resize()

void resize	(	int	width,
		int	height )

Resize the context in response to window management events.

setPixelRatio()

void setPixelRatio

(

float

ratio

)

Set the ratio of physical to logical pixels.

render()

void render

(

)

Take care of rendering the scene, requires that the context is current.

resetCamera()

void resetCamera

(

)

Reset the view to fit the entire scene.

resetGeometry()

void resetGeometry

(

)

Reset the scene geometry, this should be done when the scene geometry has changed in order to ensure correct clipping.

hits() [1/2]

std::multimap< float, Identifier > hits	(	int	x,
		int	y ) const

Return the primitives under the display coordinate (x,y), mapped by depth.

hit() [1/2]

Identifier hit	(	int	x,
		int	y ) const

Return the top primitive under the display coordinate (x,y).

hit() [2/2]

float hit	(	const Vector3f &	rayOrigin,
		const Vector3f &	rayEnd,
		const Vector3f &	rayDirection ) const

Return the depth of provided ray - geometry hit test.

hits() [2/2]

Core::Array< Identifier > hits	(	int	x1,
		int	y1,
		int	x2,
		int	y2 ) const

Return the primitives in the rectangular area provided.

isValid()

bool isValid

(

)

const

Check whether the GL context is valid and supports required features.

See also

error() to get more information if the context is not valid.

error()

std::string error

(

)

const

Get the error message if the context is not valid. Empty if valid.

camera()

const Camera & camera

(

)

const

Get the camera for this renderer.

overlayCamera()

const Camera & overlayCamera

(

)

const

Get the overlay camera.

scene()

const Scene & scene

(

)

const

Get the scene for this renderer.

solidPipeline()

const SolidPipeline & solidPipeline

(

)

const

Get the solid pipeline for this renderer.

textRenderStrategy() [1/2]

const TextRenderStrategy * textRenderStrategy

(

)

const

Get/set the text rendering strategy for this object. The renderer takes ownership of the strategy object.

textRenderStrategy() [2/2]

TextRenderStrategy * textRenderStrategy

(

)

Get/set the text rendering strategy for this object. The renderer takes ownership of the strategy object.

setTextRenderStrategy()

void setTextRenderStrategy

(

TextRenderStrategy *

tren

)

Get/set the text rendering strategy for this object. The renderer takes ownership of the strategy object.
