- For newtonian particles a "self effect" button in particle extras makes the particles be effected by themselves if a particle effector is defined for this system, currently this is a brute force method so things start getting slow with more than ~100 particles, but this will hopefully change in the future.
- Two new effector types: charge and a Lennard-Jones potential based force (inter-molecular forces for example).
-Charge is similar to spherical field except it changes behavior (attract/repulse) based on the effected particles charge field (negative/positive) like real particles with a charge.
-The Lennard-Jones field is a very short range force with a behavior determined by the sizes of the effector and effected particle. At a distance smaller than the combined sizes the field is very repulsive and after that distance it's attractive. It tries to keep the particles at an equilibrium distance from each other. Particles need to be at a close proximity to each other to be effected by this field at all.
- Particle systems can now have two effector fields (two slots in the fields panel). This allows to create particles which for example have both a charge and a Lennard-Jones potential.
Introduction of a new Delay sensor that can be used to
generate positive and negative triggers at precise time,
expressed in number of frames.
The delay parameter defines the length of the initial
OFF period. A positive trigger is generated at the end
of this period. The duration parameter defines the
length of the ON period following the OFF period.
A negative trigger is generated at the end of the ON period.
If duration is 0, the sensor stays ON and there is no
negative trigger.
The sensor runs the OFF-ON cycle once unless the repeat
option is set: the OFF-ON cycle repeats indefinately
(or the OFF cycle if duration is 0).
The new generic SCA_ISensor::reset() Python function
can be used at any time to restart the sensor: the
current cycle is interrupted and no trigger is generated.
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
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)
*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"
make soft bodies spawn threads on a mid level
use G.rt == 16 to switch to 'old style'
i am going to remove that G.rt switch if everyone is fine /* i do not intend to keep 2 versions of code up because of "BAD STYLE" */
so .. give feed back ..
-Particles were being recalculated a bit too aggressively. Normal particles didn't care, but since reactor particles have dynamic birth times they lost crucial information in the recalculation.
-The particle dupliobjects were using the objects trackflag in combination with it's rotation causing strange behavior. Now the trackflag is ignored and only the rotation of the object being duplicated is taken into account.
