Detailed Description

Apply multiple image filters on an interactive rendering of a scene.

Filters available: Box blur of fixed radius, Gaussian blur, Poisson filling, Laplacian integration, Flood filling.

Inherits CameraApp.

Constructor & Destructor Documentation

FilteringApp()

FilteringApp::FilteringApp ( RenderingConfig &  config, Window &  window  )

explicit

Constructor.

Parameters

config	the configuration to apply when setting up
window	the window to render to

Member Function Documentation

draw()

void FilteringApp::draw ( )

overridevirtual

Draw call.

Implements Application.

physics()

void FilteringApp::physics ( double  fullTime, double  frameTime  )

overridevirtual

Perform physics simulation update.

Parameters

fullTime	the time elapsed since the beginning of the render loop
frameTime	the duration of the last frame

Note

This function can be called multiple times per frame.

Reimplemented from CameraApp.

resize()

void FilteringApp::resize ( )

overridevirtual

Handle a window resize event, the configuration has been updated with the new size.

Implements Application.

showModeOptions()

void FilteringApp::showModeOptions ( )

private

Display mode-specific GUI options.

update()

void FilteringApp::update ( )

overridevirtual

Per-frame update.

Reimplemented from CameraApp.
