Detailed Description

The heart of this class library; its purpose is to hold a set of particles and manage particle creation, update, rendering and destruction.

You can add this drawable to any Geode as you usually do with other Drawable classes. Each instance of ParticleSystem is a separate set of particles; it provides the interface for creating particles and iterating through them (see the Emitter and Program classes).

◆ setDefaultAttributes()

void osgParticle::ParticleSystem::setDefaultAttributes ( const std::string & texturefile = "",
bool emissive_particles = true,
bool lighting = false,
int texture_unit = 0 )

A useful method to set the most common StateAttribute's in one call.

If texturefile is empty, then texturing is turned off.

◆ setDefaultAttributesUsingShaders()

void osgParticle::ParticleSystem::setDefaultAttributesUsingShaders ( const std::string & texturefile = "",
bool emissive_particles = true,
int texture_unit = 0 )

A useful method to set the most common StateAttribute and use GLSL shaders to draw particles.

At present, when enabling shaders in the particle system, user-defined shapes will not be usable. If texturefile is empty, then texturing is turned off.

References getLevelOfDetail(), and setLevelOfDetail().

◆ setDefaultBoundingBox()

void osgParticle::ParticleSystem::setDefaultBoundingBox ( const osg::BoundingBox & bbox)
inline

Set the default bounding box.

The default bounding box is used when a real bounding box cannot be computed, for example because no particles has been updated yet.

References _def_bbox.

◆ setDefaultParticleTemplate()

void osgParticle::ParticleSystem::setDefaultParticleTemplate ( const Particle & p)
inline

Set the default particle template (particle is copied).

References _def_ptemp.

◆ setDoublePassRendering()

void osgParticle::ParticleSystem::setDoublePassRendering ( bool v)
inline

Set the double pass rendering flag.

Double pass rendering avoids overdraw problems between particle systems and other opaque objects. If you can render all the particle systems after the opaque objects, then double pass is not necessary and can be turned off (best choice). If you set the default attributes with setDefaultAttributes, then the particle system will fall into a transparent bin.

References _doublepass.

◆ setEstimatedMaxNumOfParticles()

void osgParticle::ParticleSystem::setEstimatedMaxNumOfParticles ( int num)
inline

◆ setFreezeOnCull()

void osgParticle::ParticleSystem::setFreezeOnCull ( bool v)
inline

Set whether the particle system can freeze when culled (default is true)

References _freeze_on_cull.

◆ setFrozen()

void osgParticle::ParticleSystem::setFrozen ( bool v)
inline

Set or reset the frozen state.

When the particle system is frozen, emitters and programs won't do anything on it.

References _frozen.

◆ setLevelOfDetail()

void osgParticle::ParticleSystem::setLevelOfDetail ( int v)
inline

(EXPERIMENTAL) Set the level of detail.

The total number of particles is divided by the detail value to get the actual number of particles to be drawn. This value must be greater than zero.

References _detail.

Referenced by setDefaultAttributesUsingShaders().

◆ setParticleAlignment()

void osgParticle::ParticleSystem::setParticleAlignment ( Alignment a)
inline

Set the alignment type of particles.

References _alignment.

Referenced by META_Object().

◆ setParticleScaleReferenceFrame()

void osgParticle::ParticleSystem::setParticleScaleReferenceFrame ( ParticleScaleReferenceFrame rf)
inline

Set whether the particles should be scaled relative to world coordaintes or local coordinates.

References _particleScaleReferenceFrame.

◆ setSortMode()

void osgParticle::ParticleSystem::setSortMode ( SortMode mode)
inline

Set the sort mode.

It will force resorting the particle list by the Z direction of the view coordinates. This can be used for the purpose of transparent rendering or setVisibilityDistance().

References _sortMode.

◆ setUseShaders()

void osgParticle::ParticleSystem::setUseShaders ( bool v)
inline

Set to use GLSL shaders for rendering particles.

Particles' parameters will be used as shader attribute arrays, and necessary variables, including the visibility distance, texture, etc, will be used and updated as uniforms.

References _dirty_uniforms, and _useShaders.

◆ setUseVertexArray()

void osgParticle::ParticleSystem::setUseVertexArray ( bool v)
inline

Set to use vertex arrays for rendering particles.

Lots of variables will be omitted: particles' shape, alive or not, visibility distance, and so on, so the rendering result is not as good as we wish (although it's fast than using glBegin/glEnd). We had better use this for GLSL shaders, in which particle parameters will be kept as uniforms. This method is called automatically by setDefaultAttributesUsingShaders().

References _useVertexArray.

◆ setVisibilityDistance()

void osgParticle::ParticleSystem::setVisibilityDistance ( double distance)
inline

Set the visibility distance which allows the particles to be rendered only when depth is inside the distance.

When using shaders, it can work well directly; otherwise the sort mode should also be set to pre-compute depth.

References _dirty_uniforms, _useShaders, and _visibilityDistance.

◆ update()

virtual void osgParticle::ParticleSystem::update ( double dt,
osg::NodeVisitor & nv )
virtual

Update the particles. Don't call this directly, use a ParticleSystemUpdater instead.

float r )
