This provides a weight-paint option that only paints on vertices that have
already the weight-group assigned before. The default adds weights on all
vertices painted on.
Fixes in patch include:
- much less code
- also support for 'filter' mode
- proper code styling
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.
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.
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.
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.
- 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
- 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 ..
- 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 F3 key 'save rendered image' made inconsistant choices to save either
in jpg or tga, when the output panel was indicating to render to movies.
Even worse, it was sometimes saying 'save jpg' and saved a targa!
Made it consistantly save .jpg now, since tga isn't a good common format.
2)
Forgot to commit transform.h for previous bugfix in transform numeric input
The "generator" class for nodes then better completely disappears, also
from theme color choices menu. Since there was room for it, made the
generator themecolor to become color for 'Convertor' node types.
AO option "Use Distances" does not work for colored AO, only for "Plain".
I've added this info in tooltip, and added event that resets the color
option for AO when "Use Distances" pressed.
Weightpaint fix.
Weight painting was recoded in 2.40 to support all features from vertex
paint. That code uses a 'soft' brush by default, which makes it impossible
to assign exact weight values on a single click (which used to be possible)
I've made that an option now, so you can disable it for single-click setting
of values on vertices within the brush (if 'use vertex distances' is
set, of course).
In outliner, the icons sometimes were drawing too large or too small.
Same happened in NLA, Action, Image window etc. And it happened
for "International fonts" when set to use 'texture drawing'.
Reason: the API call for setting icon size BIF_icon_set_aspect() was not
used consistantly. Sometimes it was set, sometimes not. And even worse,
for every icon drawn in UI buttons, the icon lookup had to be done twice
because of the aspect function.
Solved it by removing this call, and adding a new function:
BIF_icon_draw_aspect()
The old BIF_icon_draw() call now draws with aspect 1.0 always. The icons
code already had optimal checking for changed sizes, zo a change in aspect
won't result in much cpu overhead. Plus it saves calling icons lookup code,
which will make it all a bit faster.
Andrea: I've added this aspect function a long while ago, I think you also
like it better how it is now? Please check!
A subsequent hotkey press like F5 now cycles through the sub-context in
buttons. However, this should not happen when clicking on Material icon
in outliner!
Sequencer:
Removing feature that allowed live updates of render progress while using
scene strips. In 2.41 and older this also happens invisible, and ESC from
it works now anyway.
Two reasons:
- it is quite annoying, especially on quit renders
- new 'render to window' conflicts too much with the sequencer window
option that shows previews (in code as well as functional!)
naming convention for Compositing:
- Render Result node -> Render Layers node (name only appears in Add menu)
- Compositor image -> Viewer Node image
I've also added a version patch (2.41 saved files only) to rename existing
"Compositor" Images.
ESC wasn't supported for sequence-based rendering yet.
Solved it with correctly initializing the sequence render with all
render callbacks, including render updates (which it didn't do yet).
Cleanup:
- Bug in ghostwinlay code: the get_mbut() function reads from the window
struct if a mouse is pressed. However, when you press the mouse in the
sequencer, which causes a render, this value was hanging because then
the active window was a render window.
- The new render display options (image window) didn't work for sequence
render OK. There was a recursion even, because a sequence draw command
calls a render, which in turn now calls redraws.
rendering now is full 32 bits. This gives drawing issues in some cards,
like ATIs.
Copied the function used for renderwindow to glutil.c, and used now in the
image window.
- removed "Unified" button, replaced with "HD" preset for 1920x1080 output
- removed the unused "Pass" options
- removed the unused "Strands" render-layer option
Because the internal render pipe supports this already; added two more
render-layer options:
- "Sky", to enable/disable sky render in a layer (this was part of "Solid"
before, not so correct... to ensure previously saved files work, the
"Sky" option is set by default when "Solid" was set. The version patching
will do this temporally always, until we've bumped up version to 2.42
- "Edge", to enable/disable edge render in a layer. Nice for compositing.
Also in this commit: fixed warnings for exported functions for the new
Node Editor pull-down menus.
- restored type choice compatiblity (plane, sphere, cube) with 2.41 release (sorry, will break saved files with CVS... my fault, should
have known.)
- removed lamp choices (lights now are different per preview, no fixed
choices).
- added checkered plane behind the plane preview. nicer for halos.
Nkey "Properties Panel" now has Dimension ("Dim") buttons too.
This reads from the actual bounding box value to see the size. Note that
dimensions for animated & deformed objects will change per frame.
(Cleaned up buttons layout for patch, and added support for Curve, Text and
Surface objects)
Next to the "DispWindow" there are now two new choices:
- Display render output to Image Editor
- Display render output to Screen-sized Image Editor
Both options won't open a 2nd window anymore, which makes work quite more
smooth even, especially because 'focus' isn't lost. Further it fits in the
'single window UI' paradigm of Blender. Should have been done 10 years ago!
Lastly it might bypass issues with X11... having 2 windows with opengl
context is not always stable in Linux.
This option uses an identical trick as for the Compositor viewer, using an
Image block with a fixed name ("Render Result").
The flow, when invoking a Render, goes as follows:
- first it checks if there's an Image Editor visible displaying the "Render
Result", if so then it uses that area-window.
(Use this option for dual-monitor setups for example, a render will always
go to the same location then)
- else it checks if there's an Image Editor open in general, it then
assigns that window the "Render Result" Image.
- else: it searches for the largest Area in the screen, and turns that into
a temporal Image Editor showing render output.
After a render, an ESC will push back the former view, if the Area type has
changed.
Same rules apply for the "Full Screen" option. Here an ESC will always go
back to the regular Screen, and restore Area type if required.
While rendering, the queue for the renderwindow isn't handled yet, so you can
not zoom (nor get full redraws), as for the regular render window.
Existing conflicts:
- in FaceSelect mode, the Image editor enforces to display the face texture
after rendering again.
- when using an Image window for compositing, you'll lose the Viewer output
on a render.
Implementation note:
While rendering updates, nothing is drawn in frontbuffer anymore. That's
good news for b0rked OpenGL drivers (and faster). However, for the few
OpenGL cards that don't do a "swap copy" but a "swap exchange" you get
issues... has to be worked on. I'm afraid we have to drop frontbuffer
drawing altogether.
Other fixes:
- Hotkeys NumPad 1, 2, 4, 8 will set zoom levels (was half coded only?)
Use SHIFT to zoom out (smaller).
- Rendering Tile updates still had draw errors on edges of tiles, in OSA
only. (Caused by commit 4 days ago)
you can click on the 'Sample' button, to sample any colour on the Blender
screen. This is really useful in the compositor, and would probably be good for
sampling footage in any eventual chroma key nodes that may be made, too.
LMB to pick the colour, ESC or RMB to cancel.
Added patch by Matt Ebb, that enhances the sequencer GUI in several ways:
- It looks a lot better
- Strip colours are themeable.
- The drawing code is more readable.
- The background of the timeline makes now distinguishing the channels easier
by alternating between different shades of gray.
- Handle-scaling is clamped to min and max-values, making it possible to
grab strips at large zooming levels more easily.
- Preview-images can be panned by dragging it with the middle mouse button.
Home-Key resets the position.
- Since some people can't grab the meaning of "C 0", it is renamed to "Chan: 0"
- Effect strips have slightly different colors to distinguish them better.
Additionally:
- fixed an off by one error in Matt's patch
- Scene-rendering saves CFRA to avoid jumping current-scene on scrub
(might be academic fix, since most likely it only happens if you add
the sequencer-scene to the timeline... But nevertheless it bugs you on
testing the GUI ;-)
Bugfix: If you use the IPO-pinning feature and edited an IPO that wasn't
highlighted as the current Sequence (current Sequence being a Metastrip),
you'll get obscure crashes, since the code
a) was mistakenly using last_seq
b) didn't test for se->ok != 2, thereby doing double frees on imbufs
Am I the only one, who wants to remove the last_seq global completely... ?
Small fix, but results are at least less frustrating now. It uses the
"compatible euler" function from inserting key positions here, preventing
euler values to be constrainted that differ weirdly.
I've tried several other approaches to get a definite rotate constraint,
but only constraining a single axes seems to me impossible magic still...
Added code to make 'Collapse Edges' handle UV's intelligently. This seems to work in just about every case that I can test, so it's turned on by default.
Also completely removed the 'collapse faces' command and code. I'm not sure what I was thinking with this in the first place since edge collapse does the same job while in in face mode. Because of this there is now just one single command that covers both situations called 'Collapse' which uses the edge collapse code.
Fulfilling a very old feature request: a new Mesh Primitives module is
introduced, which gives script writers access to the Blender mesh datablocks
created from the "Add->Mesh" menu. You can now do this:
from Blender import *
me = Mesh.Primitives.UVsphere(10,20,3) # 10 segments, 20 rings, diameter 3
ob = Object.New('Mesh','mySphere')
ob.link(me)
sc = Scene.GetCurrent()
sc.link(ob)
Added the following to the 'select' menu of 3d header and toolbox while in mesh editmode: '
-Path Select
-Edge Loop Multi-Select
-Edge Ring Multi-Select
-Loop to Region
-Region to Loop
Also added Collapse Faces and Collapse Edges to menu and toolbox as well as made them available in selection modes other than face exclusive and edge exclusive.
New Constraint API. Constraints are accessible through a "constraints"
attribute in poses and objects. Would be REALLY NICE for armature users to
pound on this code.
EM_editselection_center
EM_editselection_normal
EM_editselection_plane
These functions are used by the manipulator to get data from an editselection. regardless of weather its a face/edge/vert.
