Detailed Description

Processor that simulate particles moving through a velocity filed. Particles are initialized based on the seeds inport and are advected through the field using the Velocity Volume on the volume inport. If particles velocity has been zero for 0.5 seconds their position will be reset to a random element in the seedpoint input vector. Reseeding is done on a less frequent intervall than the advection based on the Reseed interval property. Using GLSL Compute Shaders, requires OpenGL 4.3

Inports

volume Velocity field.
seeds Starting position for particles.

Outports

particles Mesh cotaining position, color and radii buffers. Can be conntected to (for example) the Sphere Renderer Processor to render them.

Properties

Seeding Space Tells the processor which space the seeds are defined in.
Advection Speed How fast the particles will move each advection.
Advections per Frame Can be used to increase advection speed without loss of precision.
Paricle radius Maps velocity to radius of particle (For rendering that supports the Radii buffer, e.g. Sphere Renderer).
Min velocity See bellow.
Max velocity Used together with Min velocity to map velocity magnitude from [Min velocity, Max velocity] -> [0 1], used for mapping velocity to radius and color.
Velocity mapping Transferfunction to map a velocity to color.
Reseed interval Seconds between reseeding. When reseeding particles whose life is zero will get new position by selecting (randomly) from the input seed vector.

Member Function Documentation

◆ initializeResources()

void inviwo::StreamParticles::initializeResources ( )

overridevirtual

InitializeResources is called whenever a property with InvalidationLevel::InvalidResources is changes.

Reimplemented from inviwo::Processor.

◆ process()

void inviwo::StreamParticles::process ( )

overridevirtual

Deriving classes should override this function to do the main work of the processor. This function is called by the ProcessorNetworkEvaluator when the network is evaluated and the processor is invalid, i.e. some of its inports or properties has been modified, and is ready i.e. all non optional inports have valid data.

See also: ProcessorNetworkEvaluator; Inport; Property

Reimplemented from inviwo::Processor.
