3427749090 Make collision function more general so it can be used by other modifiers, too. [This is preparation work for animated smoke collision] 2012-03-20 04:15:41 +00:00

7cc206ddca Code Cleanup: remove non existing function declarations.
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count

2b7ca2304a unify include guard defines, __$FILENAME__
without the underscores these clogged up the namespace for autocompleation which was annoying.

07ee0dcc74 build system changes to eltopo, re-applied. 2011-05-02 03:44:02 +00:00
088899236b =trunk=
Recommitted eltopo collision code (but disabled by default)
with Genscher's permission.

To use, you need to install liblapack and libblas

a42bf45333 revert Joseph Eagar's eltopo commits r36073, 36075 (& some minor edits)
discussed with Janne, Ton, Nathan and we agreed this kind of change at least needs discussion with module owners.

Its also too close to release to be making these kinds of changes.

commands used:

  # reverse merge
  svn merge -r36073:36072 .
  # for some reason this gave a lot of property changes
  svn revert `svn st | grep "^ M" | awk '{print $2}'`
  # reverse merging didn't work here, removing while dir.
  svn rm extern/eltopo/


  # manually fixed conflict in
  # ./source/blenderplayer/CMakeLists.txt
  #
  # also manually removed 2 lines from
  # ./CMakeLists.txt

0a60bc14d6 =cloth collisions=
Plugged the eltopo library into the cloth solver.
I was playing with it earlier, and it's so easy to
use I decided to quickly put it in (trunk's) cloth.

See http://www.cs.ubc.ca/labs/imager/tr/2009/eltopo/eltopo.html
.  The authors are on the bleeding edge of continuous collision
detection (one of them did ILM's cloth sim).  
I
don't really have to time to plug it into softbody, particles,
bullet, fluid, etc, but doing so would be pretty straightforward.
I'll leave that up to someone else.

To use, turn on USE_ELTOPO (in cmake) or WITH_BF_ELTOPO in scons.

15669532a2 header re-shuffle, some headers contained unneeded refereces to other headers, better include inline with the C files that need them 2010-08-10 05:41:51 +00:00
666cca69e9 Cloth simulation can now use a group to specify which objects
to collide with, in addition to the effectors group.

bff893a420 Unified effector functionality for particles, cloth and softbody
* Unified scene wide gravity (currently in scene buttons) 
  instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group 
  setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
	- "Point" is most like the old effectors and uses the 
	  effector location as the effector point.
	- "Plane" uses the closest point on effectors local xy-plane 
	  as the effector point.
	- "Surface" uses the closest point on an effector object's 
	  surface as the effector point.
	- "Every Point" uses every point in a mesh effector object 
	  as an effector point.
	- The falloff is calculated from this point, so for example 
	  with "surface" shape and "use only negative z axis" it's 
	  possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer 
  just spherical.
* New effector parameter "flow", which makes the effector act as 
  surrounding air velocity, so the resulting force is 
  proportional to the velocity difference of the point and "air 
  velocity". For example a wind field with flow=1.0 results in 
  proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random 
  flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force 
  (note. the z-axis is the surface normal in the case of 
  effector shape "surface")
* New "force field" submenu in add menu, which adds an empty 
  with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector 
  system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for 
  particles, softbody & cloth, since their final effect depends on many external 
  factors, like for example the surface area of the effected faces.

Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through 
  DAG_id_flush_update(..).
  
Known issues
* Curve guides don't yet have all ui buttons in place, but they 
  should work none the less.
* Hair dynamics don't yet respect force fields.

Other changes
* Particle emission defaults now to frames 1-200 with life of 50 
  frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to 
  free pidlists after use :).

d601a51e03 RNA: added a "factor" subtype next to "percentage", and only display
% sign for percentage assuming it is between 0-100, while factor is
for values 0-1.

Move collision setting absorption from modifier to collision settings,
was inconsistent to have it there as the only one, and made it have
range 0.0-1.0 instead of 0-100.

Think global, act local!

The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.

Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
  meant for permanent, but it can probably stick there until we
  cleaned the anim system and depsgraph to cope better with
  timing issues.
- Game engine G.scene should become an argument for staring it.
  Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
  is too tightly wrapped to do it easily.

8562efe8a3 a) Forces can be hidden by deflector object now (need to talk with jahka about particle integration - should be copy-paste) see http://dldw.de/tmp/index.php?file=w2.blend (press play button in timeline and change the absorption value ob the cube) b) fixed deflector/collision bug with continues physics c) cloth wind/forces uses masses now d) even faster collision object gathering e) have fun ;) 2008-08-18 14:41:24 +00:00

c84c0201e1 Collisions: Commit of collision cleanup, put kdop-bvh structure into BLI_kdopbvh (just like kdtree interface now), huge speedup for selfcollisions, also better normal collisions (merge from cloth branch) 2008-06-03 18:48:54 +00:00
a68c03e409 Reason of all this work: Commiting my work-in-progress on reviewed collision system (better + general access to kdop, uses less memory, put it into BLI_* namespace and usage defined like existing BLI_kdtree_*). Deleted old kdop.c 2008-05-07 20:42:16 +00:00

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

af8c68ddc4 Cloth structure names update: Sorry about this commit, it will kill all your cloth settings in old files but I had to do it before release because naming convention was really bad in cloth (e.g. using SimulationSettings instead of ClothSimSettings in DNA). Same for some structure in CollisionModifier but with no sideeffects. 2008-03-20 18:28:40 +00:00
e82484b0bb Cloth: New: *simple* (OpenMP enabled) Selfcollisions available 2008-02-12 11:04:58 +00:00
69e6a6cbc9 Pointcache: Fixed non-availability when blend file was loaded from command line and also another case where you startet from an unsaved blend and switched to a saved one; Cloth: Fixid mass init, little speedup for collisions; Collision Modifier: More generalized it 2008-02-11 13:30:52 +00:00
