Plus: moved particle interaction and effect buttons back to a single
Object context. The proposed solution (sub context) has workflow issues,
(adds another click (no hotkey) to view settings)
whilst almost all Object buttons nicely fit in single view still.
This was on todo since first particle commit, actually the idea was to
move particle related issues to a special sub-context, but leave the
effects themselves in the Object main menu. Splitting off Particles from
the Effect system isn't in the scope of what is feasible now.
Also note; the current panel 'particle interaction' actually should be
a generic 'forces and collision' panel, since it's also relevant for
soft body feature (WIP)... that can be changed later.
old files still use the old fast OSA, and when you want a specific
material to have specular/shader/texture AA you can set this individual.
When rendering ray_mir or ray_transp or ray_shadow the new OSA will be
effective by default however.
Still todo; make this switch work for transparant faces and unified...
- now more than 31 channels possible for ipos
- added lotsa new channels all over
- Texture block has ipo now too
- recoded getname_ei functions
(Will ask nathan to give release log info when he's back!)
This problem appeared to be a famous one, with some fun read to be found
on the web. The solution as I commit here is described on the site:
http://www.blender3d.org/cms/Misc_improvements.355.0.html
As extra (I needed it quite some!) added requested feature to have the
renderwindow display in titlebar whether the spare page is shown (JKEY)
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.
toggle for all pivot modes. The 2 new pivot modes have been removed
from the popup.
Instead, a new toggle button is added to the 3d view header.
2) Grab cursor mode. Cursor can be grabbed (and constrained to axis, grid,
etc. while moving) like any other object. If no object is selected,
GKEY alone grabs the cursor, otherwise pressing CKEY while in GKEY mode
moves the cursor.
instead of right.
This basically swaps left and right, in most window spaces
so you can choose between:
LMB: Cursor/time slider/paint - RMB: Select
or LMB: Select - RMB: Cursor/time slider/paint
Aimed at:
1. Newbies
2. 1 button mouse mac users
3. People like me who are sick of having to constantly keep putting their brains into different modes when
switching between other apps and Blender :)
Yes, the User Preferences window is a bit of a nightmare
now, a layout cleanup will be forthcoming soon...
3d Cursor, only Ob Centers
Median Point, only Ob Centers
They prevent rotation/scaling from effecting the scale/rotation of the objects and just effects their position.
This is handy for aligning objects if you constrain to an axis and scale, as well as other neato things :)
Intrr came up with the code and I hacked it into the GUI
- "Global Pivot": Maintains a global Pivot and Align mode setting for
all 3d views when enabled, instead of seperate settings per 3d view
- "Auto Perspective": Switch to ortho mode automatically on 1/3/7, and
to Perspective when the view is rotated with the mouse
- "Align mode": As suggested on the list, when enabled, transformations
on several objects only transform their locations, not their sizes or
rotations.
- Grid dotted when not 1:1
***ATTENTION***! The User Interface parts of these features have not been
committed, as I work on my own modified UI here. The three features need
toggle buttons to turn them on and off.
I used the following 3 buttons (first two features are in userprefs,
third as a 3d view setting):
uiDefButBitS(block, TOG, USER_AUTOPERSP, B_DRAWINFO, "Auto Persp",
(xpos+edgespace+(3*medprefbut)+(3*midspace)+smallprefbut+2),y3+10,smallprefbut,buth,
&(U.uiflag), 0, 0, 0, 0,
"Automatically switch between orthographic and perspective");
uiDefButBitS(block, TOG, USER_LOCKAROUND, B_DRAWINFO, "Global Pivot",
(xpos+edgespace+(4*midspace)+(4*medprefbut)),y3+10,smallprefbut,buth,
&(U.uiflag), 0, 0, 0, 0,
"Use global pivot setting for all 3d views");
uiDefIconButS(block, TOG|BIT|10, B_AROUND, ICON_ALIGN,
xco+=XIC,0,XIC,YIC,
&G.vd->flag, 0, 0, 0, 0, "Translate only (align)");
Someone needs to add these to the interface in an appropriate manner!
Thanks.
Added the missing anti-aliasing pixel filter size and threshold parameters for manual AA control (disable 'Auto AA' button).
Added support for yafray raytraced depth-of-field.
Added extra panel for Camera in edit window to edit dof paramaters.
The actual focus point will be drawn as a cross when camera 'ShowLimits' is enabled, similar to the aqsis code in tuhopuu.
Note to users: raytraced DoF is very slow, for best results, the default AA parameters are not good enough, especially with higher aperture values (more blur).
So for best results, disable 'Auto AA' and set the AA parameters yourself.
It works best with multi-pass AA ('AA passes' > 1) and a reasonable 'AA samples' value, something in the range 8 - 25 or even higher.
Currently the post-process DoF is not available in yafray, alternatives are being worked on.

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.
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)
The changes from the original include the ability to add a blurred edge with a selectable width to the wipe and to rotate the effect.
Has these sweep types included already
-single
-double
-iris
These still need to be coded
-box
-cross
-clock
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...
Kent Mein. So next to the mix, mult, add, sub we have now:
- Div: divides by texture color
- Screen: is like Mult, but works opposite (makes lighter)
- Diff: the difference between texture color and material
- Light: if texture is lighter it shows (per component)
- Dark: if texture is darker it shows (per component)
Next step: add this for specular and mirror, and the other channels...
I commit it now because it also fixes error in previous commit.
http://www.blender3d.org/cms/Ramp_Shaders.348.0.html
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
This for all current NKEY menus by default. Can be standard for each hotkey
controlled Panel from now on; use toggle_blockhandler() for it.
Another popular request: hotkey enabled Panels now optionally reopen on
the previous location, instead of under mouse. This option "Pinned" is a
user option now. Optional for later; have it as per-panel option... dunno!
The last request, close on mouse-exit, won't be implemented, this intrudes
with Panel consistancy, and is pretty OK solved with NKEY-NKEY now.
this consists of 22 different ways to sweep from 1 strip to another. For you windows lovers: it's like "Blinds" in Powerpoint :)
- in the NKEY menu you can choose which type you want perform, vertical, horizontal, in/out etc. it's too much to decribe.
Credits for this go to Kent 'Sirdude" Mein who coded the sequence plugin I stole the code from.
To allow certain sequence effects to have settings, I also added a "varstr" void pointer to the Sequence DNA, that can point to a special struct for each effect. This is similar to how plugins are handles.
more neat effects to come....
Needs latest yafray, you can get it from cvs, but I have also binaries
for os x here:
http://www.coala.uniovi.es/~jandro/noname/downloads/yafray-0.0.6-3.pkg.zip
To use it, go to yafray panels (global settings) and uncheck the "xml" button.
That would tell the export code to avoid xml export and use the yafray plugin
instead. You'll see the render being draw while running and you can even stop it
with ESC key.
Since I'm sure problems will appear, expect updates soon.
Remember: does not work on win32
types:
- Continue: is default, old style
- Dolly: is like previous, but not continuous
- Scale: is the new method. Name is based on fact it scales view
is calculated in where_is_object.
Negative scale is found by a cross product of first 2 rows in matrix, and
comparing that (dot product) with third row.
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.
Kester: since this is in DNA, it backwards converts all R into B now,
which isn't the bug. On big endian systems (OSX) there engine colors
are OK, which indicates the conversion of MCol goes wrong on the
engine side, by using some endian-sensative approach.
The main confusement is, that the MCol struct isn't in use for read
or write in Blender, only for a save in files. The contents of that
struct is wrong, yes. See note in vpaint.c top.
"Sphere": spherical mapping for a 360 degree panorama
"Tube": cylindrical mapping for a 360 degree panorama
Both mappings by default do only the sky (upper) hemisphere. The color
below is same as regular Horiz and Zenith colors, useful for setting
an AO effect.
Sample pics:
http://www.1000skies.com/fullpanos/index.htm (commercial)
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.
appeared that the standard size (64x64x64) just works fine for small
scenes, like a single character in a small environment. Larger scenes and
larger environments became exponentional slower.
Disadvantage of larger octrees is longer build time, and overhead traver-
sing it though, so something to tweak based on some experimenting.
A table with test results + blender file will be in CMS soon.
New button is in F10 Render panel, in bottom. Last free spot there! O_o
Sizes supported now 64, 128, 256 or 512.
fixes, including:
- Panel in action window (disabled it, since there's no need for it)
- fix: when action was added to mesh with vertex keys, the action couldn't
be deleted, nor did action window draw key names
- mouse on RVK (key) in Action window: Nkey menu pops as well.
This is not a good candidate to put in Panel, no selection possible here.
- when you change name of RVK in action window, it shows in IpoWindow too
it for the UV Image window (as Nkey replacement). Blendix can take
this further now.
Other little improvement: vertices in UV window now draw unselected
first, and then selected over it. Less confusing!
Next spaces: Action and Nla.
- 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!
* Updates to the cygwin build.
the dna.c file used to be generated with a full path. Cygwin doesn't like
this. The problem was with some cflags and linkflags that are used to build
makesdna.exe
Hos nicely pointed this out and proposed a solution.
Now, these flags are only added to the command when the platform != 'cygwin'.
* Updated some variables in SConstruct.
- 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..
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!
- Draw Faces in the UV editor
- Draw Faces, selected in the UV editor, in the 3D view
- Draw Shadow Mesh in the UV editor (for faces unselected in the 3D view)
- Select Linked UVs (LKEY)
- Unlink Selection (Alt+LKEY)
- Stick (Local) UVs to Mesh Vertex on selection
- Active Face Select
- Reload Image
- Show / Hide Faces in the UV editor (H, Shift+H, Alt+H)
- Proportional Editing (O, Shift+O)
- Stitch, Limit Stitch UVs (snap by mesh vertex)
- Weld / Align UVs (WKEY)
- UVs Snap to Pixels on/off switch
- RMB in Texture Paint or Vertex Paint mode picks color
- Select Inverse in Faceselect mode
I hope these are all the features that were commited. The new UV Mapping
panel (and code) will follow later.
