Member Function Documentation

cancelRender()

void ParticleRenderer::cancelRender ( )

overridevirtual

Stops the rendering if it is currently in progress.

Implements IRenderer.

Definition at line 387 of file ParticleRenderer.cpp.

initialize()

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

overridevirtual

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.

Todo:

could be changed to AOS to sort only once

Implements IRenderer.

Definition at line 199 of file ParticleRenderer.cpp.

isInitialized()

bool ParticleRenderer::isInitialized ( ) const

overridevirtual

Checks if the renderer has been initialized.

Implements IRenderer.

Definition at line 269 of file ParticleRenderer.cpp.

render()

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

overridevirtual

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, ...)

Implements IRenderer.

Definition at line 290 of file ParticleRenderer.cpp.

Member Data Documentation

cameraDir

Vector ParticleRenderer::cameraDir

colors

Array<Rgba> ParticleRenderer::colors

Definition at line 40 of file ParticleRenderer.h.

idxs

Array<Size> ParticleRenderer::idxs

Definition at line 37 of file ParticleRenderer.h.

palette

Optional<Palette> ParticleRenderer::palette

Color palette or NOTHING if no palette is drawn.

Definition at line 46 of file ParticleRenderer.h.

positions

Array<Vector> ParticleRenderer::positions

Positions of particles.

Definition at line 34 of file ParticleRenderer.h.

vectors
