drawImplementation(State&) is a pure virtual method for the actual implementation of OpenGL drawing calls, such as vertex arrays and primitives, that must be implemented in concrete subclasses of the Drawable base class, examples include osg::Geometry and osg::ShapeDrawable. drawImplementation(State&) is called from the draw(State&) method, with the draw method handling management of OpenGL display lists, and drawImplementation(State&) handling the actuall drawing itself.
Implements osg::Drawable. Reimplemented in osgParticle::ConnectedParticleSystem. |

Reuse the i-th particle.
Reimplemented in osgParticle::ConnectedParticleSystem. |
|
Set the alignment vectors.
|
|
Set the X-axis alignment vector.
|
|
Set the Y-axis alignment vector.

A useful method to set the most common |
|
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. |
|
Set the default particle template (particle is copied).
|
|
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. |
|
Set whether the particle system can freeze when culled (default is true).
|
|
Set or reset the frozen state. When the particle system is frozen, emitters and programs won't do anything on it. |
|
(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. |
|
Set the alignment type of particles.
