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.

◆ 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()

Identifier hit ( int  x,
int  y 
) const

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

◆ 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.

◆ 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.
