Thinking Particles (TP) is an advanced particle system. The API is defined in c4d_particles.h .

• TP data is stored in a scene hook with the ID ID_THINKINGPARTICLES .
• TP_MasterSystem is the scene hook class that gives access to the particles in the scene.
• TP_PGroupArray stores particle groups of the type TP_PGroup .
• TP_ParticleNode represents a single particle and stores its ID.

If a plugin wants to use TP it must call InitThinkingParticles() when the message C4DPL_STARTACTIVITY is sent to PluginMessage() (见 插件函数手册 ).
