Member Function Documentation

void CamViewWidget::initializeGL ( )

protectedvirtual

OpenGL initializations

Reimplemented from RenderBase.

void CamViewWidget::paintGL ( )

protectedvirtual

rendering:
- draw viewport filling square with camera frame as texture
- clear depth buffer
- draw virtual objects using view- and projection matrices of the current camera

Reimplemented from RenderBase.

void CamViewWidget::resizeGL ( int  w, int  h  )

protected

when window size is changed

void CamViewWidget::setCamera ( Camera *  cam)

slot

sets the camera that delivers frames and transformation matrices

void CamViewWidget::setFramerate ( int  fps)

slot

does nothing right now

Member Data Documentation

Camera* CamViewWidget::cam

protected

the camera that delivers frames to display

QTimer* CamViewWidget::updateTimer

protected

triggers the rendering of a new frame, now hardcoded to fire every 5ms => 200fps..

ViewportSquare* CamViewWidget::viewportSquare

protected

a viewport filling square to draw the camera frames
