A bit shorter internal names for bparticles structs and functions. |

Added particles sequence in state bpy api. |
April 22, 2014, 09:23 (GMT) |
Added 'attributes' sequence property in the state type. |

Custom get/set methods for the "Particle" type. This supports particle attributes directly as python properties in the particle wrapper type. If a particle identifier has no corresponding data in the state yet it will be automatically created when writing. |
April 22, 2014, 09:23 (GMT) |
Added "name" property (read-only) for attribute states. |
April 22, 2014, 09:23 (GMT) |
Added new python module 'bparticles' for implementing a full python API to define particle states. This is necessary because otherwise the RNA can only refer to data that already exists in the DNA library (bpy.data) but not create temporary structs. The state should be defined separately before replacing a particle system's state with it. This is similar to how bmesh works. |

Basic submodule 'types' in bparticles, defining a PyObject type for the particle state. |
April 22, 2014, 09:23 (GMT) |
Added python type for particle attribute state in the bparticles module. |

Flags for particle attributes: - REQUIRED: These attributes are always existent in every particle system. Currently this is only the "id" layer, position might also be added - PROTECTED: Attribute name, datatype, etc. can not be changed. Only user-defined attributes can be modified this way. |

Clear the attribute buffers when adding new particles to a state. This should probably use a specific default value for each attribute at some point. |
April 22, 2014, 09:23 (GMT) |
Initialize the "id" attribute when adding particles to the state. |
April 22, 2014, 09:23 (GMT) |
RNA fix: using RNA_def_struct_sdna_from works only with actual pointers, but not with directly nested structs (NParticleAttributeDescription in this case). Resort to including "desc." prefix in the property paths. |
April 22, 2014, 09:23 (GMT) |
Use a readonly flag for attributes and a second variant of the Data RNA access types to prevent writing over immutable attributes ("id" in particular). |
April 22, 2014, 09:23 (GMT) |
Add position attribute to particles by default. |
April 22, 2014, 09:23 (GMT) |
Basic display feature for particles. This is organized as a list of NParticleDisplay in the modifier for now. Each NParticleDisplay adds a visualization element of some type in the viewport, which will allow combining elements for custom attributes with standard display modes for particles. |
April 22, 2014, 09:23 (GMT) |
Use the new attribute flags to determine editability in RNA. |
April 22, 2014, 09:23 (GMT) |
Added missing read/write code for particle display. |
April 22, 2014, 09:23 (GMT) |
Alternative particle iterator init method using a specific particle ID. |
April 22, 2014, 09:23 (GMT) |
Store the particle state in iterators instead of the particle system. |
April 22, 2014, 09:23 (GMT) |
Yet another restructuring effort: Separate the state from the particle system settings. Attributes can be accessed by name in the state data, for now this uses plain linear search in a NULL-terminated array, but can eventually use a hash table for O(1) lookup. |
