Member Function Documentation

cancelRender()

virtual void IRenderer::cancelRender ( )

pure virtual

Stops the rendering if it is currently in progress.

Implemented in ParticleRenderer, MeshRenderer, IRaytracer, and ContourRenderer.

initialize()

virtual void IRenderer::initialize ( const Storage &  storage, const IColorizer &  colorizer, const ICamera &  camera  )

pure virtual

Prepares the objects for rendering and updates its data.

Called every time a parameter changes. Renderer should cache any data necessary for rendering of particles (particle positions, colors, etc.).

Parameters

storage	Storage containing positions of particles, must match the particles in colorizer.
colorizer	Data-to-color conversion object for particles. Must be already initialized!
camera	Camera used for rendering.

Implemented in VolumeRenderer, RayMarcher, ParticleRenderer, MeshRenderer, and ContourRenderer.

isInitialized()

virtual bool IRenderer::isInitialized ( ) const

pure virtual

Checks if the renderer has been initialized.

Implemented in VolumeRenderer, RayMarcher, ParticleRenderer, MeshRenderer, and ContourRenderer.

render()

virtual void IRenderer::render ( const RenderParams &  params, Statistics &  stats, IRenderOutput &  output  ) const

pure virtual

Draws particles into the bitmap, given the data provided in initialize.

This function is called every time the view changes (display parameters change, camera pan & zoom, ...). Implementation shall be callable from any thread, but does not have to be thread-safe (never will be executed from multiple threads at once).

Parameters

params	Parameters of the render
stats	Input-output parameter, contains run statistics that can be included in the render (run time, timestep, ...), renderers can also output some statistics of their own (time used in rendering, framerate, ...)

Implemented in ParticleRenderer, MeshRenderer, ContourRenderer, and IRaytracer.
