Viewer coupled with a basic diffuse path tracer. The user can move the camera anywhere and trigger a path-traced rendering. Can also display the raycaster acceleration structure.

Inherits CameraApp.

Constructor & Destructor Documentation

PathTracerApp()

PathTracerApp::PathTracerApp ( RenderingConfig &  config, Window &  window, const std::shared_ptr< Scene > &  scene  )

explicit

Constructor.

Parameters

config	the configuration to apply
window	the window to render to
scene	the scene to render

Member Function Documentation

draw()

void PathTracerApp::draw ( )

overridevirtual

Draw call.

Implements Application.

physics()

void PathTracerApp::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()
