Description

The particle file format is a simple ASCII listing of the current status of every particle in the system. Rendering, mass, generator, and other information is carried in the wire file or SDL file. The file is all space-separated:

Field	Type	Comments
<file_type>	Integer	Two possible values currently: 4 or 5
<num_blobs>	Integer	The number of particles in this file.

<blob_info> (See the following table. There are 'num_blobs' entries of this type.)

Normal particles

For type 4 particles (normal), information for each blob is described below.

Field	Type	Comments
<start_x>	Float	X position of particle at start of frame.
<start_y>	Float	Y position of particle at start of frame.
<start_z>	Float	Z position of particle at start of frame.
<end_x>	Float	X position of particle at end of frame.
<end_y>	Float	Y position of particle at end of frame.
<end_z>	Float	Z position of particle at end of frame.
<R>	Float	Red color of particle in this frame.
<G>	Float	Green color of particle in this frame.
<B>	Float	Blue color of particle in frame.
<cycles_left>	Integer	Number of cycles left in the particle’s life.
<cycles_total>	Integer	Total number of cycles in the particle’s life.

Diffusing gas particles

For type 5 particles (diffusing gas particles), information for each blob is described below.

Field	Type	Comments
<start_x>	Float	X position of particle at start of frame.
<start_y>	Float	Y position of particle at start of frame.
<start_z>	Float	Z position of particle at start of frame.
<end_x>	Float	X position of particle at end of frame.
<end_y>	Float	Y position of particle at end of frame.
<end_z>	Float	Z position of particle at end of frame.
<R>	Float	Red color of particle in this frame.
<G>	Float	Green color of particle in this frame.
<B>	Float	Blue color of particle in this frame.
<cycles_left>	Integer	Number of cycles left in the particle’s life.
<cycles_total>	Integer	Total number of cycles in the particle’s life.
<start_size>	Float	Size of particle at start of frame.
<end_size>	Float	Size of particle at end of frame.
