Different draw mode for Vortex effector ( http://www.clubinfo.bdeb.qc.ca/~theeth/Temp/vortex.jpg )
Use row buts for effector type (only one effector at a time per object).
Forcefield circle transparency in 3D view is controlled by falloff value (for coolness factor).
Please note that those only draws in the 3D view for Empty objects. I've tested with all other object types through a global call, but lamps (and only those) give problems. Since we go in release status soon, I prefer commiting something that works all the time.
- small additions and fixes to enable the demo mode;
- Added sleep() to Blender.sys and 17 new functions to Blender.Window module:
things to help demo script writing and as a bonus read / write access to Blender's input event queue;
- updates in docs, those interested please check Window.py in python/api2_2x/doc/ to read about the new Blender.Window functions.
----
Demo mode should be working well now for (I) playing rt animation -- aka ALT+A -- and (II) rendering pics and anims and playing anims. I'll still add access to radiosity data and functions.
PS: Joseph Gilbert made (II) possible with the Scene.Render module he added for 2.32. He's been coding great things for bpython, so I'd like to take the chance to point that and thank him here.

Implementation Least Squares Conformal Maps parameterization, based on
chapter 2 of:
Bruno Levy, Sylvain Petitjean, Nicolas Ray, Jerome Maillot. Least Squares
Conformal Maps for Automatic Texture Atlas Generation. In Siggraph 2002,
July 2002.
Seams: Stored as a flag (ME_SEAM) in the new MEdge struct, these seams define
where a mesh will be cut when executing LSCM unwrapping. Seams can be marked
and cleared in Edit Mode. Ctrl+EKEY will pop up a menu allowing to Clear or Mark
the selected edges as seams.
Select Linked in Face Select Mode now only selects linked faces if no seams
separate them. So if seams are defined, this will now select the 'face group'
defined by the seams. Hotkey is still LKEY.
LSCM Unwrap: unwrap UV's by calculating a conformal mapping (preserving local
angles). Based on seams, the selected faces will be 'cut'. If multiple
'face groups' are selected, they will be unwrapped separately and packed in
the image rectangle in the UV Editor. Packing uses a simple and fast
algorithm, only designed to avoid having overlapping faces.
LSCM can be found in the Unwrap menu (UKEY), and the UV Calculation panel.
Pinning: UV's can be pinned in the UV Editor. When LSCM Unwrap is then
executed, these UV's will stay in place, allowing to tweak the solution.
PKEY and ALT+PKEY will respectively pin and unpin selected UV's.
Face Select Mode Drawing Changes:
- Draw Seams option to enable disable drawing of seams
- Draw Faces option to enable drawing of selected faces in transparent purple
- Draw Hidden Edges option to enable drawing of edges of hidden faces
- Draw Edges option to enable drawing of edges of visible faces
The colors for these seams, faces and edges are themeable.
transformation (from vertex -> world space), used defines for vecadd and
vecsub, and intersects quads more efficient.
Result is about 2 times faster.
- Added draw mode for empty used as forcefield
- added defines VECADD and VECSUB
Cleaned the GUI for effectors: Widen the panel and the buttons. Made the button text more conformed.
Added vortex field for particles. Particles swirl around z-axis of the object. Little hackish, could be made better.
Edges in Mesh
- adds automatic when you use creases. For other situations; call the
void make_edges(Mesh *me) in mesh.c. Of course, once in editmode the
edges are automatically recreated.
- in F9 buttons you can add/remove edges too
- both for Mesh and DisplistMesh, so it speeds up drawing quite some in
wireframe
- render for edges can't work... edges have no material nor tface nor col..
so here still the faces are rendered in wire
Creases in Subsurf
- based on the code by Chris McFarlen
- main changes is that now edges are used, saving quite some data in file
- use SHIFT+E in editmode to set edges-sharpness. values go from 0-1
- in F9 buttons you can set draw-crease mode. It draws now blended from
wire color to edge-select color (as provided in Theme)
Known issue: setting sharpness on 1 cube (subdiv 2) gives weird results
with some values... Chris, can you check?
Further; code cleanups, changing 0 in NULL when needed, no warnings, etc etc
* removed 32 channel limit (can now have 50, or of you know what number to change, 999 ;)
* added new IPOs: mirror fresnel and fac, transparency fresnel and fac, and glow factor transparent materials (add)
for Armature. Note: only works for subsurfed Mesh now!
Change in drawobject.c: Halo option on subsurf Mesh now draws points.
but using the original vertices...
- textures: added support for new mixers (div, diff etc) to work on the
other map-to channels too, like ref or spec
Also it works on lamp and world textures
- brought back uncommented line of code that was removed by leon, to have
particle motion based on textures
- recoded the glPylonOffset hack to be nice function, this for future
testing.
- hotkeys, obdatacopier and renameobjectbyblock, all from Jean-Michel Soler (jms);
- bevel_center by Loic Berthe, suggested for inclusion by jms;
- doc_browser, by Daniel Dunbar (Zr)
Thanks to them for the new contributions!
(I included doc_browser at 'Misc' because only users interested in script writing would actually use it, but it could also be under 'Help'. Opinions?)
BPython related:
- Added scriptlink methods to object, lamp, camera and world.
- Object: added object.makeTrack and object.clearTrack (old track method).
- sys: made sys.exists(path) return 0 for not found; 1 for file, 2 for dir and -1 for neither.
- doc updates and fixes.
- made ONLOAD event work. G.f's SCENESCRIPT bit was being zeroed in set_app_data.
- Blender: updated functions Load and Save to support the builtin importers and exporters besides .blend (dxf, videoscape, vrml 1.0, stl, ...)
- Draw: added mouse wheel events.
- Scene: added scene.play to play back animations (like ALT+A and SHIFT+ALT+A). Makes a good counter, too, when the 'win' attribute is set to a space that doesn't "animate".
The scene.play() addition and the fix to ONLOAD scriptlinks is part of the work for a Blender demo mode. It already works, but I'll still add support for Radiosity calculations and fix a thing in main(): it executes onload scripts too early (BIF_Init), giving funny results in alt+a animations and renderings when firing up Blender. Loading after the program is up has no such problems. When I finish I'll post examples of demo mode scripts.

Material color and specular now can be defined by a Colorband. The actual
color then is defined during shading based on:
- shade value (like dotproduct)
- energy value (dot product plus light)
- normal
- result of all shading (useful for adding stuff in the end)
Special request from [A]ndy! :)
polygonization of 512 MetaBalls:
- version 2.33a: 76 s
- current cvs version 8 s
- button "Never" is added in button window: Metaballs are polygonized only during render time (it is useful for particle animation) http://e-learning.vslib.cz/hnidek/misc/bowl_metaballs.blend
New is that objects can have a force field, and Meshes can even deflect
(collide) particles. This is in a new sub-menu in Object buttons F7
The full instructions where on the web, Leon mailed it me and I will put
it in CMS tomorrow. For those who like to play with it now, here are demo
files:
http://download.blender.org/demo/test/
Quite some changes where in the integration though... so previous created
particle deflectors will not work. Changes to mention now are:
- gravity is renamed to 'force field'
- force field and deflector options are in Object now, not in Mesh
- the options also have its own struct, doesnt add to Object by default
- force fields are possible for all object types, but only work on center.
So empty objects are typical for it.
Work to do:
- add draw method in 3d win to denote forcefield objects
- check on the UI (panel with different size?)
- add 'recalc' button in deflector panel
OpenGL draw.
(BTW: the previous commit also solves raytrace errors with negative scaled
objects...)
Further a cleanup of displaylist flags and object/base flags. The #define
ACTIVE is moved to filesel.c (only used here).
The GONNA_MOVE #define got a OB_ added in front.
The Image texture repeat options, now allow a "Checker" repeat. With
odd and even tiles set separately, and a size button to set a
'Mortar' inbetween tiles.
http://www.blender3d.org/cms/Render_engine_features.215.0.html
Also fixed bug: using 'CalcAlpha' option for image textures didn't give
antialised edges for image.
- fixed two warnings, unused var in Object.c and undeclared function in script.c
- updated Blender.Draw doc, it was missing info about Button object
- refactored pytype initialization to try to fix for once platform (and distro!) specific crashes on startup. This asked for tiny updates in Effect.[ch] (removed static from declaration, moved definitions to the .c file) and modules.h
- fixed error I made trying to fix scripts w/ no [eol] char in menus. Thanks Michael Velikanje for reporting the problem!
played (= packedfiles opened and copied to another block) these
packed data blocks where not freed.
The error showed in console at closing of Blender, like:
read_struct len: 24 0x1c4423c
Problem: when appending data, it called the local_all() function, which
indeed made all data local, including all other dynamic linked data.
Not very nice... but mixing dynamic & appending data from single file is
headcrunching code.
Solution: when appending data, it now only makes local_all() the data from
that specific library file, leaving dynamic data from other files linked.
(Bug report 1183)
mesh_add_normals_flags()
Basically this abuse was only for normals and draw flags. For huge imports
the editmode hack is far too slow.
Now added to vrml importer. Hos can check for his stl work!
- AO energy slider to control amount
- option "Use sky color" for colored AO. The horizon color will define
bottom diffuse color, the zenith works on top
- option "Use sky texture" will do a full sky render to define AO color
Please note that AO energy and color only is found when a ray does not
intersect. So for interior scenes make sure 'Dist' value is sufficient
low.
New also is:
- World "Map input" allows "Ang Map" (Angular mapping) which can be used
for 360 degree spherical maps, aka as Light Probes. Check samples here:
http://www.debevec.org/Probes/
Note that Blender doesn't support HDRI images yet, but option "Use sky tex"
already gives intersting results with such images
- World sky rendering with Image Textures now correctly filters and uses
antialiasing. Also noticable for raytrace mirror reflections
- World preview render for sky type "Real" now gives correct view as
defined by current used camera.
I tried to speed up AO tracing with coherence systems, none of it really
worked yet... time to tackle octree itself i guess!
When more than 30 scenes are in a scene, the sequencer "Add" option didnt
show a databrowse window.
This was a nasty one, because databrowse facilities are more-of tied to
having a header. The fix is that I added option to IDnames_to_pupstring()
to not limit the menu (by passing NULL for menu short pointer).
Also noticed a bug with pupmenu_col(), which did return on a val==0 event
(mouse release) which shouldn't be, this makes sequences of menus not
possible.
Animated metaballs didn't update correctly when changing frame, this when
they were parented (for example) to an object with Ipo.
The fix consists of three things:
- the test_displist() call doesn't remake displist anymore, but frees it.
this works, because when drawing an mball object it checks for a displist
and creates one when needed
- the main drawing routine drawview3d() now has a separate loop where first
all objects are updated with where_is_object(), then they're drawn.
This effectively solves lag for mballs. Might improve other lags too!
- included in NumPad-9 call to test_displist() too, to force a full upgraded
3d view
CTRL+SHIFT+A (apply lattice deform) on a Bezier Curve object was not
implemented yet. Added this.
Little sidenote: when curves are 2D the result will remain 2D, disregarding
deformation in 3rd dimension.
- Ambient Occlusion is a more sophisticated ambient trick, which takes
nearby faces into account by firing a hemisphere of shadow-rays
around. AKA 'dirt shader'.
- Eeshlo made it a Lamp type, which doesn't fit well. I've moved the
settings to the World menu, and let the Material->ambient value control
the amount it contributes
- currently, the AO value is added/subtracted/mixed with the 'diffuse'
factor while shading, before it is multiplied with Material color
Buttons are in new Panel 'Amb Occ" in F8 menu. Note:
- "Dist:" by shortening the length of rays you get subtler effects and it
renders faster too
- "DistF:" the attennuation factor gives control over how the 'shadow'
spreads out.
Further it's just raytracing, so tends to be slooooow.... :)
Here same tricks as for other raytraced scenes apply, especially try to
keep the environment as small as possible (exclude faces from Octree by
giving them no Material Traceable).
I still have to think over a couple of aspects, will await feedback on it:
- AO color? Now it just adds 'white'
- other sampling patterns? I tried dithering, which was so-so
- method of controlling final 'samples' in F10? Might be useful for other
oversampling too (area light) to have it reacting to a percentage or so..
The real bug is in the matrices blending function which doesn't handle non-uniform scaling correctly.
I've minimized the occurence of the bug by calling the blending function only when the influence is smaller than one (woah, optimisation AND bug fix!)
This should make the bug disappear approximatly 90% of the time since people don't use influence all that often (also, this only applies to constraint that are alone, not using influence IPOs to switch between two constraints).
I'd solve the blending function bug, but I haven't had much time to dig into it really.
Incidently, by reverting to the previous code, this solves bug #1069http://projects.blender.org/tracker/index.php?func=detail&aid=1069&group_id=9&atid=125
Basically this provides three new things:
1. Choice of a list of noise-base functions, which can be used by the
current Clouds, Marble, Wood textures as well.
2. Three new texture types: Musgrave, Voronoi and DistortedNoise
3. Python access to noise functions (not for render!)
All of this together makes Blender's builtin procedural textures a LOT
more powerful. Here again, a full webpage should be made to show off all
possibilities, and explain some of the more scientific names for settings.
A good read on Musgrave textures can be found here:
http://www.ypoart.com/Downloads/Musgrave.htm
About Voronoi:
http://www.ypoart.com/Downloads/Worley.htm
I can't find official DistortedNoise docs easily... maybe its something
Eeshlo created himself.
I've spent some time to change the patch Eeshlo provided. Worth noting:
- created main texture "Musgrave" with 5 sub choices (instead of 5 new
main textures)
- added for all new textures the option to scale (zoom in out)
- added patch in do_versions to initialize variables
I hope the Python team will check on the Noise.c API. And include in docs!
binary subformats, and writes the binary subformat. Read is done with
usual F1, write is done in the menu 'File->Export Selected->STL'. Writes
meshes only, writing the 'displistmesh' if subsurf is on. The 'magic'
to determine whether it is reading the binary or ASCII subformat
could use a little work, but makes the correct choice most of the time.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them
That was about it.
There are a few things that needs double checking:
* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
- added mesh_set_smooth_flag, mesh_delete_material_index function
- isolated some globals
- got rid of reliance on meshdata in buttons_editing.c and material.c
(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
of source that actually edit mesh *data* vs. areas that just edit
mesh object information.
