2008-08-19Particles now got that force-hiding feature, too --> jahka: please take a ↵Daniel Genrich
look :)
2008-08-18a) Forces can be hidden by deflector object now (need to talk with jahka ↵Daniel Genrich
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 ;)
2008-08-15Simpledeform origin is no longer attache to parent by defaultAndre Susano Pinto
That was due to a current limitation on dag system.. that leads to cyclic dependencies. So now you can attach the origin of a simpledeform to an empty and mark whether its affected by the relative position of empty or the global one. brecht found a workarround to solve the cyclic dependency by using a parent of both the mesh and the control empty: empty_parent | |-> empty controlling simpledeform |-> mesh with simpledeform modifier
2008-08-14Added subsurface levels option to normal projection.Andre Susano Pinto
Now when doing normal projeciton is possible to ask it to project along the normals that the vertex would have if it was subsurfaced... this gives "better" projections on low polys. Point of this commit is to add the feature request from Eclectiel http://blenderartists.org/forum/showpost.php?p=1181531&postcount=9 workflow as Eclectiel wanted is now possible: to archieve a nice low-res retopology that aproximates a high-res mesh when subsurfaced: 1 - make base low-poly retopo 2 - apply a shrinkwrap with projection along normal.. and with SS level = N (where N>0) 3 - add a Subsurface with level N 4 - run bretch's script (ss_fit)
2008-08-13Fixed a typoAndre Susano Pinto
I was using the word "kept" (past tense) instead of "keep" (basic form). I hope my english teachter dont sees this commit xD
2008-08-13*Added documentation mainly at shrinkwrap.cAndre Susano Pinto
*removed commented code about the dropped shrinkwrap options *Removed references to "cut plane", "limitMesh".. its now called "auxiliar target" *Added option to shrinkwrap over an selected axis *"Normal projection" mode is now called "projection" since it can now project over "normal, and any combination X, Y, Z"
2008-08-04SimpleDeform modifications:Andre Susano Pinto
* Added "Lock axis" options on taper and strech/squash (suggested by ZanQdo) * Better control of deform factor (suggested by ZanQdo) * Added eModifierTypeFlag_AcceptsCVs (so it now accepts both curves and meshes)
2008-07-26Fixed simple deform strech/squash functionAndre Susano Pinto

2008-07-25Converted shrinkwrap to a DeformOnly modifierAndre Susano Pinto
*the options "remove faces", "merge" points were removed *made shrinkwrap work with CVs (curves and nurbs surfaces) *cleanup shrinkwrap code.. (removed bruteforces and raytree methods)
2008-07-19*Added "kept" mesh above surface option on shrinkwrap to nearest surfaceAndre Susano Pinto
changed a few code relative to project over normal mode (to try to kept code generic and more independent of modifier itself)
2008-07-04*Added vertex groups on simple deformAndre Susano Pinto
*Fixed a few UI things *Make SimpleDeform and Shrinkwrap to use vertexgroup_get_vertex_weight, a similar function "static float vert_weight(MDeformVert *dvert, int group)" existed on modifier.c, changed it a bit and moved into BKE_deform.h
2008-07-04Added modes Squash and Strech to SimpleDeform (need testing)Andre Susano Pinto
CHanged the add modifier menu to show a submenu for selecting the type of simpledeform.

+Added limits on bend +button to create an empty and make child of object +empty is now relative to object
2008-06-24Adding initial SimpleModifier (bend,taper,twist)Andre Susano Pinto

2008-06-21Added cut-plane option.Andre Susano Pinto
Its now possible to project 2 planes over a model and get a cloth.. Tought it still has a few issues.. related with distance to kept from mesh.
2008-06-18Patch #8882 - Falloff in the wave modifierBen Batt
This patch adds the ability to specify a falloff radius in the Wave modifier. Currently only linear falloff is supported. Thanks to Michael Fox for the patch!
2008-06-17Added merge option to shrinkwrap when using projection mode (bruteforce for now)Andre Susano Pinto
Changed code to remove faces (now quad faces that got one vertice projected are turned on tri) Merge option is still not very usefull since shrinkwrap does not yet moves unprojected vertices
2008-06-12Patch #8613 - Vertex groups in the mirror modifier.Ben Batt
This patch re-assigns the mirrored data to use vertex groups with "mirrored" names (e.g. L_arm -> R_arm, Leg.R -> Leg.L etc.). Vertex groups with the "mirrored" names must already exist in the base mesh. This means that it is no longer necessary to apply the mirror modifier in order to rig the mirrored data independently. Thanks to Michael Fox for the patch!

BLI_kdopbvh (just like kdtree interface now), huge speedup for selfcollisions, also better normal collisions (merge from cloth branch)
2008-05-31Added culling on normal projection.Andre Susano Pinto
Now renderdemon is happy ;) and now shrinkwrap can be used for bulging :)
2008-05-08Reason of all this work: Commiting my work-in-progress on reviewed collision ↵Daniel Genrich
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
2008-05-07Normal projection:Andre Susano Pinto
+added option to remove faces where all vertices got unprojected Nearest surface point +15% faster closest point on point-tri function (archived by projecting the point on tri-plane and solving the problem on 2D) (its still using bruteforce on triangles.. I'll add the right data structure later)
2008-05-03Added control over distance to kept form target meshAndre Susano Pinto
Quad bug was fixed by splitting the quads that are feed to RayTree
2008-05-02+normal projection optimized with RayTree (RE_raytrace.h)Andre Susano Pinto
+control for normal projection direction (default,inverted,both) There are some bugs on projection over quads.. it seems to work 100% on fully triangulized meshs
2008-04-27Implemented shrink modes are now:Andre Susano Pinto
+ Nearest surface point + Normal projection + Nearest vertex (gives similar results to nearest surface if the target mesh has many vertexs and is a lot faster to calculate) ^^ all bruteforce calculation for now + fixed matrix order multiplication + request for CD_MDEDEFORMVERT
2008-04-25Shrinkwrap skeleton codeAndre Susano Pinto
+vertex weights supported +target object now saves to file: load/save works :) for now simple moves objects vertexs to the nearest vertexs on target object (so that I can test if its working correctly with the modifier API)

2008-04-10Point Cache RefactoringBrecht Van Lommel
======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.
2008-03-20Cloth structure names update: Sorry about this commit, it will kill all your ↵Daniel Genrich
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.
2008-02-24-> Bevel tools and Bmesh kernelGeoffrey Bantle
The following is a commit of Levi Schooley's bevel code and the bmesh library it depends on. The current editmode bevel has been replaced with a new per edge bevel function. Vertex beveling is also availible. To set weights for the modifier to use, use the ctrl-shift-e shortcut on either edges or vertices. Recursive beveling is turned of for the time being.

2007-12-02ParticlesBrecht Van Lommel
========= Bugfix for crash with disabling the particles system and saving/loading files, the way it detected if the mesh had changed could not work correct.
2007-11-27ParticlesBrecht Van Lommel
========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.
2007-11-16Long outstanding feature request: "Multi Modifier"Ton Roosendaal
This allows to mix between the result of 2 modifiers, with both using the same input state. This is useful for having a mesh deform and armature deform working together. However! This functionality could have been presented better... this is actually Node editor stuff! Now it works by adding a "MM" button, next to the "overall vgroup" option. If MM is pressed, the input of this modifier is the same as the input of the previous modifier. Only the armature modifier has this option now...
2007-11-13==Mirror Modifier==Chris Want
Support for using the axes of a different object as the line of mirror symmetry for a mirror modifier. As a nice consequence, this allows "clipping" to arbitrary planes in editmode. A fun example of using a couple of mirror modifiers and an array modifier to easily make a nice flower type model is here: http://bebop.cns.ualberta.ca/~cwant/chocolateC05.blend
2007-11-12Mesh Deform ModifierBrecht Van Lommel
==================== Dynamic binding support. This means that the mesh can move _within_ the cage and still deform correct. If the mesh goes out of the cage, don't expect correct result. Must be enabled with the 'Dynamic' option, because it is slower and consumes more memory. This is useful to use e.g. the cage mesh for main deformations and still have shape keys for facial deformation working.
2007-11-06Mesh Deform ModifierBrecht Van Lommel
==================== Added a button to invert the vertex group influence, to make blending between mdef and armature deform easier.
2007-11-05Mesh Deform ModifierBrecht Van Lommel
==================== The MeshDeform modifier can deform a mesh with another 'cage' mesh. It is similar to a lattice modifier, but instead of being restricted to the regular grid layout of a lattice, the cage mesh can be modeled to fit the mesh better. http://www.blender.org/development/current-projects/changes-since-244/modifiers/ Implementation Notes: - OpenNL has been refactored a bit to allow least squares matrices to be built without passing the matrix row by row, but instead with random access. MDef doesn't need this actually, but it's using this version of OpenNL so I'm just committing it now. - Mean value weights for polygons have been added to arithb.c, a type of barycentric coordinates for polygons with >= 3 vertices. This might be useful for other parts of blender too.
2007-07-29Armature CrazySpace ImprovementBrecht Van Lommel
=============================== An improved CrazySpace correction is now used for Armature modifiers that use vertex groups, and that are the first enabled modifiers in the stack. This is a a specific case, but also a common one. http://www.blender.org/development/current-projects/changes-since-244/skinning/ Implementation Notes: - The quaternion crazyspace correction is still used for modifiers other than the armature modifier. - Modifiers can now provide a deform matrix per vertex to be used for crazyspace correction, only the armature modifier implements this now.
2007-04-30Really minor updates related to code I wrote for the Cast modifier:Willian Padovani Germano
- modifier.c: moved a check out of a loop, removed an unneeded var, made a couple cosmetic changes. - DNA_modifier_types.h: added parentheses to cast and smooth modifier defines that used bit-shifting (like 1<<1, etc.). Note: realized they were needed when I tried to use "flag &= ~MOD_CAST_Z" in modifier.c. Since MOD_CAST_Z is #defined as 1<<3, ~MOD_CAST_Z ended up as ~1<<3 while I wanted ~(1<<3). There are other places in that header file and others in Blender where it'd be safer to add the parentheses... - Updated the epydoc documentation for the features added by Ben Batt to the cast modifier; fixed small typo in API_intro.py. BTW, thanks Ben Batt (artificer) for checking, improving with a couple features and committing these modifiers :).
