Orange branch: Revived hidden treasure, the Groups! Previous experiment (in 2000) didn't satisfy, it had even some primitive NLA option in groups... so, cleaned up the old code (removed most) and integrated it back in a more useful way. Usage: - CTRL+G gives menu to add group, add to existing group, or remove from groups. - In Object buttons, a new (should become first) Panel was added, showing not only Object "ID button" and Parent, but also the Groups the Object Belongs to. These buttons also allow rename, assigning or removing. - To indicate Objects are grouped, they're drawn in a (not theme yet, so temporal?) green wire color. - Use ALT+SHIFT mouse-select to (de)select an entire group But, the real power of groups is in the following features: -> Particle Force field and Guide control In the "Particle Motion" Panel, you can indicate a Group name, this then limits force fields or guides to members of that Group. (Note that layers still work on top of that... not sure about that). -> Light Groups In the Material "Shaders" Panel, you can indicate a Group name to limit lighting for the Material to lamps in this group. The Lights in a Group do need to be 'visible' for the Scene to be rendered (as usual). -> Group Duplicator In the Object "Anim" Panel, you can set any Object (use Empty!) to duplicate an entire Group. It will make copies of all Objects in that Group. Also works for animated Objects, but it will copy the current positions or deforms. Control over 'local timing' (so we can do Massive anims!) will be added later. (Note; this commit won't render Group duplicators yet, a fix in bf-blender will enable that, next commit will sync) -> Library Appending In the SHIFT-F1 or SHIFT+F4 browsers, you can also find the Groups listed. By appending or linking the Group itself, and use the Group Duplicator, you now can animate and position linked Objects. The nice thing is that the local saved file itself will only store the Group name that was linked, so on a next file read, the Group Objects will be re-read as stored (changed) in the Library file. (Note; current implementation also "gives a base" to linked Group Objects, to show them as Objects in the current Scene. Need that now for testing purposes, but probably will be removed later). -> Outliner Outliner now shows Groups as optio too, nice to organize your data a bit too! In General, Groups have a very good potential... for example, it could become default for MetaBall Objects too (jiri, I can help you later on how this works). All current 'layer relationships' in Blender should be dropped in time, I guess...

- Made SoftBody work with Particle Force Fields. - Added new (Particle) Deflector; type Wind. Wind gives constant directional force. It is animatable (Ipos) and reacts to Object scaling. Also uses FallOff. Works for particles and SoftBody quick movie check; http://www.blender.org/bf/0001_0250.avi test file is in download.blender.org/demo/test/wind_soft.blend - Added MaxDist option for forcefields, to control its influence better. Is drawn as circle in 3d window. Forcefields are a bit weak still... should react to scaling, or not; in that case drawing should indicate it (done for spherical field now).

/* particle deflector */
fixed small glitch multiplying nodemass twice (thanks ton) claened up sbObjectStep(...) to follow 'time step rules' added really care for framerate in scene renamed arguments in softbody_calc_forces(...); and softbody_apply_forces(...); for better reading fixed particle integration to be ODE solver compatible

The long awaited Particle patch from Janne Karhu http://www.blender3d.org/cms/New_Particle_options_a.721.0.html There's no doubt this patch had a lot of good ideas for features, and I want to compliment Janne again for getting it all to work even! A more careful review of the features and code did show however quite some flaws and bugs... partially because the current particle code was very much polluted already, but also because of the implementation lacked quality. However, the patch was too good to reject, so I've fixed and recoded the parts that needed it most. :) Here's a list of of most evident changes in the patch; - Guides support recoded. It was implemented as a true 'force field', checking all Curve path points for each particle to find the closest. Was just far too slow, and didn't support looping or bends well. The new implementation is fast (real time) and treats the paths as actual trajectory for the particle. - Guides didn't integrate in the physics/speed system either, was added as exception. Now it's integrated and can be combined with other velocities or forces - Use of Fields was slow code in general, made it use a Cache instead. - The "even" distribution didn't work for Jittered sample patterns. - The "even" or "vertexgroup" code in the main loops were badly constructed, giving too much cpu for a simple task. Instead of going over all faces many times, it now only does it once. Same part of the code used a lot of temporal unneeded mallocs. - Use of DerivedMesh or Mesh was confused, didn't work for Subsurfs in all cases - Support for vertex groups was slow, evaluating vertexgroups too often - When a vertexgroup failed to read, it was wrongly handled (set to zero). VertexGroup support now is with a name. - Split up the too huge build_particle() call in some parts (moving new code) - The "texture re-timing" option failed for moving Objects. The old code used the convention that particles were added with increasing time steps. Solved by creating a object Matrix Cache. Also: the texture coordinates had to be corrected to become "OrCo". - The "Disp" option only was used to draw less particles. Changed it to actually calculate fewer particles for 3D viewing, but render all still. So now it can be used to keep editing realtime. Removed; The "speed threshold" and "Tight" features were not copied over. This resembled too much to feature overkill. Needs re-evaluation. Also the "Deform" option was not added, I prefer to first check if the current particle system really works for the Modifier system. And: - Added integration for particle force fields in the dependency graph - Added TAB completion for vertexgroup names! - Made the 'wait cursor' only appear when particles take more than 0.5 sec - The particle jitter table order now is randomized too, giving much nicer emitting of particles in large faces. - Vortex field didn't correctly use speed/forces, so it didn't work for collisions. - Triangle distribution was wrong - Removed ancient bug that applied in a *very* weird way speed and forces. (location changes got the half force, speed the full...???) So much... might have forgotten some notes! :)

removed my SB hack from particle collision code (which still can't really handle moving targets) leaving 2 bug fixes 1. multiple objects need a reset on cache variable 2. quads always need to be handled as 2 triangles (since they don't need to share a plane) added a collision detecting function in effect.c for SB ( no need to be there, but i did not find a better place ) but should handle 'moving targets' up to 0.2 blender units/frame well .. important info in this case: collision uses 'face normal' to decide if *intrusion* happend uses 'damping' of collision target to slow down movement when *intrusion* happend +some more removing unneeded code in softbody.c

fixed spacing in the headers to get rid of some warnings and some other little minor spacing issues.
