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...
images (like used for rendering icons).
When working during Orange on new render pipeline, I've left this topic
alone for a while... subpixel precision testing is very time consuming and
needs concentration for a while. :)
This commit brings back precision as it was for 2.41. Below a short
explanation of the solved issues.
- the window matrix for rendering is kept constant during all OSA passes,
this to ensure clipping happens for each pass identically.
- a subpixel offset is only applied on filling in the z-buffer
- this offset is inverse corrected for shadepixel code, only on 2 places
Another nasty issue is that for filtered rendering (gauss etc), the tiles
(or entire image) is temporally increased 2 pixel in size. This caused a
'dark' (or sky color) edge on the rendering. During Orange that was solved
with a hardcoded clipping offset value, which only corrected for larger
pictures (like > 500 pixels in size).
Now this clipping offset is correctly calculated, based on render size.
Last issue: the view border in 3d window was calculated using integers,
giving small errors in display too. Now it uses float, so visually the
view border is more close to what a render shows.
Didn't realize that LMB+ALT was used for middle mouse emulation. Changed
the vertex snap modifier key for knife tool to 'CTRL' and fixed problems
with the drawing of the header instructions.
Also changed color of the knife tool to match that of loopcut tool. This
is easier to see and more consistent from a UI standpoint as well.
Manipulator orientation tweak: when having multiple objects selected, the
orientation option "Local" was always skipped, showing it global. Now it
uses the orientation of the active object.
The bug reportor noticed a conflict with the "Around" option "Active". In
that case he expected the orientation to be from Active Object as well.
- draw-extra for Lamps did not follow selection color
- Surface objects were drawing curves always in unselected color, also its
draw-extra options didn't follow selection color then
Previously the knife tool only allowed you to cut through edges. This
approach is limited however, since many times you want to cut through
vertices in order to create precise cuts or terminate a cut in a specific
way. Blenders knife tool now supports cutting through vertices as
demonstrated in these pictures:
http://briggs.zanqdo.com/newknife1.jpghttp://briggs.zanqdo.com/newknife2.jpg
Since the vertex intersection code is very precise, vertex snapping has
been added to the knife tool to assist the user when they wish to cut
through vertices and can be toggled by pressing and holding the 'alt' key.
Notes:
-Vertex cutting and vertex snapping are only available when using the
'knife exact' option.
-Added various fixes to the precision of the knife tool.
When a sequencer has mixed use of 32 bits and float images (note, Scene
strip returns float image too), the old 32 bits image should be freed,
otherwise it keeps saving that image.
- 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)
Preview render in 3d window: when window type changes (like 3d window to
UV window), and you change the window size, and restore to 3d view, the
rendered preview had to be re-initialized.
texture.c: a return was added without value.
- buffer overflow was possible with providing a file path argument longer
than 256 characters.
- buttons "VCol Light" and "VCol Paint" were not mutual exclusive
- quicktime error menu (unable to create) had a enter in end
- deleting points in CurveMapping button (like Curves node in compositor)
did not give proper recalc event
- edges render menu had a tooltip still mentioning the unified render
* Renamed Text3d.Font.New() to Text3d.Font.Load() since New was acring like load anyway.
* Text3d.Font.Get() was just calling Text3d.Font.New(),
made it get from a name or return a list of all fonts.
* implimenetd getsetattrs
* removed references to bones in the error messages
* added users variable
* renamed name to filename and added access to id.name
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.
Everyone else was using gzip. On the latest downloads many of them
are using bzip2, (I think everyone using scons)
So I decided to update make release so that everyone is using
gzip2. I don't mean to step on anyones toes, I know at least some of
the platform maintainers do not use make though so feel free to change
it back and or to something different for your platform.
While I was at it I also changed default path of OPENEXR to /usr on linux.
Was suggested on mailing list by Matt.
(I'm pretty sure the linux maintainer is using scons)

committed them.

- pending commit for OSX intel systems, with intel graphics. These now call
an extra swapbuffers after glFlush(). Code is ifdeffed, and doesnt affect
other systems.
- show-off commit: option to have transparent nodes over the composite
result. Only draws Image for active Viewer Node now, and image doesnt
translate nor zoom (which isnt bad though).
Set in themes the alpha color of "node backdrop" to make nodes
transparent.
- 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.
vec.normalized()
mat.inverted()
mat.transposed()
made vec/float possible
normalize/invert/transpose now return None because they modify the data in place.
use the ...(ed) versions to return a modified copy.
Fixed Memory leaks from not decreffing PyFloat_AS_DOUBLE from these python functions...
(found when testing above functions)
ob.rbMass
ob.rbRadius
matrix.determinant()
quat*float
vec*float
matrix.transpose()
EXPP_setModuleConstant
Checked all instances of PyFloat_AS_DOUBLE so I dont think there are any mroe leaks there.
