modifier.
The bug was caused by an endless loop in the Array modifier's calc_mapping
function. The loop worked under the assumption that there could not be sets
of vertices such that (for example) vertex A merges with vertex B and vertex
B merges with vertex A. As it turns out, this situation is possible, so the
loop got stuck going from A to B to A to B ad infinitum.
This commit fixes the problem by limiting the number of loop iterations with
the copy number for which the mapping is being calculated. This should also
give more correct results in general.
data, due to the temporary "Weight-coloured" TFace data being replaced by
the original before displaying. This commit fixes that by changing the type
of DerivedMesh calculated by mesh_calc_modifiers when no non-deforming
modifiers are applied from MeshDerivedMesh (which depends on the original
Mesh) to CDDerivedMesh (which doesn't depend on the original Mesh).
Compositor: Rotate Node
It only delivers RGBA buffers for now. Also Image size is unaltered, so
parts get cropped away. Doesn't work with translation Node before this
node yet.
RGB values if they are returned by the texture function. This fixes an issue
reported by several people where Image textures gave no displacement unless
CalcAlpha was turned on.
a vertex group which will modulate the influence of all bones in the armature.
This commit also tidies up the height of the modifier panels; they should all
have the same size margin now.
exception of the clone tool.
One level undo for image- and texturepaint, only storing those tiles
that changed.
Test to improve texturepaint performance using glTexSubImage2D, only
enabled with 2^n sized textures and mipmapping off. Painting a 2048x2048
texture is then pretty smooth here, as long as the geometry is not too
complex.
Particle distribution error when using Vertex Weights.
In the unlucky case the last face in a Mesh has no weight (zero), the code
that tries to distribute particles evenly accidentally could assign it
still a particle, because of the 'remainder' calculus.
Also only happens in cases where the remainder has a value.
So a workaround is also to increase/decrease amount of particles.
- this patch adds verse support for SCons, which can be enabled by
giving WITH_BF_VERSE=1, ie. on command-line
- this patch also adds a custom lib dir possibility. From the patch description:
"To set a custom ../lib dir, put LCGDIR="path to lib dir, including the platform folder name!" in your user-config.py."
* Fixed win32-vc-config.py so that it links to the proper library. Reported by Brandano.
of the fluidsim can now be disabled with the
flag: BF_NO_ELBEEM='true', e.g. for irix systems.
(The number of ifdefs from the original
patch was reduced, and the defines are now
only necessary when elbeem is switched off.)
- particle generation option is available again
[ #4337 ] Cant refresh the C:\
[ #4710 ] Wrong paths in file selector under user prefs
[ #4353 ] Using ^ char + click on Open/Load = Blender crash
Details:
Fixes for root paths like C:\ on Windows, where Blender still used '/'.
Also contains fixes for relative paths:
- no relative paths for the default dirs (forced to absolute)
- message if using relative paths when .blend file hasn't been saved.
Lastly also added '.' for refresh in root paths. Windows
FindFirstFile/FindNextFile also return '.' and '..', but not in root paths like C:\
Compositor: Image nodes used for Movie files didn't convert the relative
paths (if used), so it could not load the movie file.
This bug explains why sometimes movies worked in the Compositor... so for
the current release the bypass is to disable the "Relative" button in the
File Window.
The Blur node didn't pass on a buffer when the 'factor' value was not
exactly zero. Tiny values (like 0.0000001) or even negative ones were
still handled by the blur code.
Boundbox code for display lists lacked a check for empty Curve/Surface
objects, causing a boundbox to be giant (initialized huge values). That
frustrates code like 'view3d home', or 'centered object view'.
(Commit in view.c is only a little bit code cleanup)
Reports came in that Elephants Dream files crash on quit or loading other
files. Was caused by freeing Material Nodes, which was accessing memory
that potentially was just freed before (node->id). Apparently only Windows
really gives issues then, which is actually a good thing :)
New toolsettings variable "select_thresh" was not initialized. This caused
the option "similar normals" to not work really (uses a dot product).
It now is initialized (scene.c) as well as corrected in do_versions for
saved files.
really cool to get this working solidly, but there are many potential problems with the
triangle face creation across the flat surfaces, especially when there are holes inside
the curves. Maybe this could be a fun project for someone better at this than I? :)
Taper object curves still cause similar problems...
* Made the curve radius affect the 'Nsize' curve normal drawing too, so you don't need a
bevel to see the value.
This is a much faster and easier way to give a bevelled curve a taper, without
using taper curves. Each point on a curve now has a 'radius' value that you can
shrink and fatten using Alt S, which will influence the taper when the curve is
bevelled (either with a bevob, or with front/back turned off and a bevel dept
set). Alt S shrinks and fattens the selected points in an interactive transform,
and you can set an absolute radius for selected points with 'Set Radius' in the
curve specials menu.
See demo: http://mke3.net/blender/etc/curve_shrinkfatten-h264.mov
This can be a quick way to create revolved surfaces (eg.
http://mke3.net/blender/etc/wineglass-h264.mov ) and it would be very
interesting to use this radius value in other tools, such as a 'freehand curve'
tool that would let you draw a curve freehand, with the radius affected by pen
pressure, or even using the radius at each point to control curve guides for
particles more precisely, rather than the continous maxdist.
Posemode, Wkey option "Select constraint target" did not work for Copy
Scale constraint.
Also added a check for NULL pointer, constraint targets cannot exist...
- It saves a file with indicated type on each change, with number
appended denoting the current frame (like ANIM saving).
- Output filename button supports relative paths ("//")
- Shows optional preview image too
- For now, added a print on each file save as feedback
To make this option work nicely, changed the BKE_makepicstring() function
to have less globals inside, so it is more generic. Todo: allow amount of
digits in filenames to be set (to support files like tmp_123456.jpg)
other are changes so calchandles_ipocurve only calc handels on a bezier line.
This makes bvh import faster but should also speed up internal IPO operations.
This material node takes an input value of any size and fits it to a sigmoid curve (value between 0 and 1) The width of the curve can set to make the sigmoid fall off faster (bigger number) or slower (smaller number) and the centerpoint (what value is mapped to 0.5) can be adjusted as well. Anyone smarter than me can feel free to tweak this and make it better.
moment, but they can useful so rather than let them go to waste I've merged and
committed them.

- ImagePaint now uses ImBuf directly, and the rect blending functions
were moved into the imbuf module.
- The brush spacing, timing and sampling was abstracted into brush.c, for
later reuse in other paint modes.
Float ImagePaint support.
Textured Brushes:
- Only the first texture channel is used now.
- Options for size and offset should be added, but need to find some space
in the panel, or add a second one ..
* Combine RGBA
Basically the opposite of separate RGBA, brings 4 value channels into a single
RGBA image). Has interesting possibilities for reordering channels, when used
with separate RGBA!
* Dilate/Erode
Originally written by Brecht van Lommel, with some minor modifications and
tweaking by myself. Positive distances dilate, negative distances erode.
* I also added the 'value' field to the hue/saturation node. Minimal extra cost,
and can be handy.
- Code for brush spacing and timing was rewritten, making spacing more even.
Example: http://users.pandora.be/blendix/brush_spacing.jpg
- Instead of Stepsize for regular brushes and Flow for airbrushes, there is
now Spacing for both, and Rate for airbrushes.
- Airbrush now works more like it does in the Gimp now, by maintaining the
spacing even if the brush moves faster than the painting rate.
- Some preparations to make brushes work in texture paint mode.
- Added a new Brush datablock, only used by image paint, but intended
to be used in texture paint, vertex paint, weight paint and sculpt
mode also.
- Being a datablock, these brushes can be saved, appended and linked.
They have a fake user by default, to make sure they are saved even if
not selected.
Image Painting:
- Replaced the img module with C code in imagepaint.c
- Airbrush is no longer a separate tool, but rather an option that can
be used for soften, smear and clone also.
- Blend modes mix, add, subtract, multiply, darken and lighten have been
added, code taken directly from vertex paint.
Note to project files maintainers:
- The img module was removed from SCons and Makefiles, and this should
be done in other build systems also. I'll wait to remove the module
from cvs, to not break compilation.
The VectorBlur node crashed when it didn't get a RGBA type image as
input (like using Alpha as input). Added typeconversion for it.
Note: the Z input and Vector input are not converted, but checked for.
When an improper type gets connected to these inputs, an error is
printed in console.
When adding a new node in a group, the call to refresh input/output
sockets was called after a compositing update was executed.
Just moved this call 2 lines up.
This also uncommits the fix from Joilnen, the stack pointers in the node
system are *per definition* set. If NULL, it's an indication something
else is wrong.
Composite: the Translate Node only worked in some cases (pixel processor
call), and not for:
- filter
- seperate rgba
- conversion of buffer types (value to rgba etc)
Blur still doesn't either, but that code is too optimized to add quick.
Will put on todo for checking on better unification of translations.
