virtual void ParticleShader::clear (   )  [inline, virtual]

Definition at line 56 of file ParticleShader.h.

void ParticleShader::draw (   )  [virtual]

each shader knows how to draw all the particles based on its attributes Reimplemented in ParticleShaderChain, ParticleShaderCluster, ParticleShaderGradientField, ParticleShaderLink, ParticleShaderStroke, and ParticleShaderTriangle. Definition at line 79 of file ParticleShader.cpp. References drawParticle(), ParticleStuff::ps, and Particles::size().

void ParticleShader::drawParticle (  int  i  )  [virtual]

each shader knows how to draw a particle based on its attributes Definition at line 107 of file ParticleShader.cpp. References applyTransformations(), drawShape(), ParticleStuff::ps, Particles::selectedParticle, and setColor(). Referenced by draw().

virtual void ParticleShader::drawShape (  int  i  )  [inline, virtual]

each shader simply make a shape call for each particle Reimplemented in ParticleShaderConstMaterial, ParticleShaderCurvature, ParticleShaderCylinder, ParticleShaderDisk, ParticleShaderSphere, and ParticleShaderTeapot. Definition at line 51 of file ParticleShader.h. Referenced by drawParticle().

void ParticleShader::removeMe (   )  [virtual]

Remove the shader from the current particle system. Implements ParticleStuff. Definition at line 50 of file ParticleShader.cpp. References ParticleStuff::name, ParticleStuff::ps, and Particles::shaders.

void ParticleShader::setColor (  int  i  )  [virtual]

determine the color Definition at line 89 of file ParticleShader.cpp. References ParticleMaterial::color, ParticleMaterial::getDiffuseBack(), ParticleMaterial::getDiffuseFront(), and material. Referenced by drawParticle().

void ParticleShader::setParticleSystem (  Particles *  new_ps  )  [virtual]

Set the particle system the ParticleStuff points to. Also adds the ParticleStuff to the particle system. If this is a new particle system, this deletes the ParticleStuff from the existing particle system. 2002-10-26 Wen Pure virtual function at the ParticleStuff level. Made concrete in ParticleAttribute, ParticleBehavior, etc. Not pure any more, since all the children do the same thing, it is easier just to inherent this one. 2003-11-05 Wen Very important, every one MUST call this before using this class. This is used to initialize the system. Since the factory can create a ParticleStuff with a ps=NULL, we must handle initialization step as a separate function, in order to not calling the same code twice I decided not to call this function in all the constructors. Reimplemented from ParticleStuff. Definition at line 26 of file ParticleShader.cpp. References addMeTo(), and ParticleStuff::ps.
