Blender Git Commits

- add some windows specific defines to BIF_gl.h so that OpenGL can
be used without including windows.h - this is the main reason windows.h
is included in so many places and this change allows most of those
inclusions to die.

Global G.moving got nice define flags, and additional meaning.

- move object mode
- move editmode/pose mode
- move with widgets

- part of BLI_winstuff.h cleanup

Some cleaning up of BLI_winstuff.h usage
- removed reference in render.h (really bad, shouldn't include a platform
specific header so widely unless really necessary)
- added M_PI, M_PI_2, M_SQRT, M_SQRT_2 defines to BLI_arithb.h... this is
a better place as it is more the "standard" blender math header. left
in winstuff.h as well for the moment for simplicity
- other changes are patches to code so everything works ok with this
shuffling.

Little fix; while Transform() in editmode, and other objects were select,
these objects were drawn in transform color (white usually)

New version of rotate handlers. I like it! Now the rest of you ;)

BPython:
- Added Blender.Run(script) + doc update (forgot to mention in my previous commit).

Trying to fix two mistakes from my previous commit:

- nmesh.transform(): forgot yesterday that affine vectors have 4th component = 0, now updated normals transformation accordingly.

- As Ton pointed, recursive parsing of scripts dirs in search of scripts was a mess. I simply forgot about the "//" trick and much worse, to protect against worst cases ("/", for example). Now the code uses BLI_convertstringcode to take care of "//", doesn't process if dir = "/" and there are limits:

max depth for traversing subdirs = 4
max dirs in the tree = 30.

I'll work more on this, check more, but these changes were tested and should make the code safer, of course, so I'm committing. Sorry about the mess, I should take lessons on defensive programming ...

Fix for building on win32

Added transform_manipulator.c to the windows MSVC 6.0 projectfile

Added curly braces around an #ifdef NEWTRANSFORM.
Needed when NEWTRANSFORM was not defined.

Transform widgets; Scale and Rotate versions

To use; press the (temporal) icon in header. Switching widget types is by
pressing G, R or S once, if current widget type is different it switches,
otherwise it goes to normal Transform().

Widgets need a bit test for picking accuracy, correct drawing etc.
The rotate widget has a center button for 'trackball' rotate. That latter
can also be used for hotkey-based rotate.

In current code, all widgets remain in "Global" space, also in editmode.
Also widget updates while using normal transform has to be done.

2 Bugfixes:
- rotate in PoseMode had error for 2d 'around' center
- transform in postemode could crash, due to typo (& or |)

BPython:

- Scripts:
fixed error in "Save Current Theme" which prevented it from automatically updating script registration in menus.
cosmetic changes in a couple of Campbell's sel_same.py script strings + more descriptive name for its new menu place (3d view, face mode -> select menu).
small updates to help_browser.py script.

The above changes are related to this:
- Added new script menu entries: Render (for exporters to renderers), Themes, FaceSelect (this already at the proper place). Updated Scripts win->Scripts menu so it won't show all available entries, only the ones we mean to see there.
- Updated menu registration so that scripts folders can become trees. The release/scripts/ dir should be updated soon with subdirs like converters/, modifiers/, generators/ or whatever -- better discuss first (or is it? /me afraid of long irc discussions during meetings :) ).

- Modules:
Blender: added 'udatadir' option to .Get() function and added var Blender.mode to tell if Blender is in bg or interactive mode.
NMesh: added Campbell's nmesh.transform(matrix, recalc_normals = False) method (reworked, so my fault if it doesn't work).

- Bugs fixed:
#2123: http://projects.blender.org/tracker/?func=detail&atid=125&aid=2123&group_id=9
Reported by Ken Hughes (thanks!), who also found the exact problem later (it was in Text.Load, not with script links -- if only I had checked emails these days ... lost > 1 hour today to find the problem: passed filename to M_Text_Load was later being written over by a function called by add_text). Also saw that Text.Load wasn't checking existence of passed filename (duh!), now it does.

#1655: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1655&group_id=9
Reported by Chris Want (thanks!): command line "blender -P script" not working properly for bg mode ("blender -b blendfile -P script").
Had to make some small updates to get it working (bg mode for scripts was never explicitely handled, it worked due to collateral effects, let's say), interested readers can check the report after I update it or the API_intro.py doc file. After more testing we can make further updates. Updated many places to not call redraws if in bg mode, now it is officially available. Blender outputs its own info when rendering in bg mode, if that is considered a nuissance we'll have to add a few "if (during_script())" calls outside bpython.

- Removed a few warnings here and there and also updated docs.

- patch submitted by guitargeek
-includes:
*Text3d accessors - ablity to manipulate FONT objects through python
*update to Object.link - calls text_to_curve upon ob_font link for drawing
*update to constant.h - constant type checking define
*update to curve.c - clamp values on getters/setters
*clean up of Text3d module

- adds /GR to compiler options for generating run time type info for c++ classes in the debug release
- add support for new transform files

Individual Element (object) center for Rotate and Resize. Note that using this in edit mode is a bit useless right now, but we have some surprises in our bozo bin :P

Transform can switch mode on the fly again (GRS).

Fixed a bug with the BIF constraint call, needed to call startConstraint and normalise the space matrix (this affected the manipulator).

Forgot to cvs add a file!
Also did the SConscript file.

MSVC users have to add this!

So! Finally a show-off of the *power* of Martin P's work! :)

- Made framework for 3d Transform Manipulators (widgets)
- The Manipulators act like '2d buttons', by default with LeftMouse and with
while-hold-move-release
- Implemented now: Translation Widget, which allows:
- four hotspots for axis grab or view-aligned grab
- center defined by 'around' setting
- SHIFT+LMB gives planar constraint on other 2 axes
- works in Object mode and Edit mode (not posemode yet)

Enable it with (temporal) icon in 3D header. All other 'normal' transforms
then keeps working btw.

On the todo for this widget:
- choice for Global, Local or Normal orientation

The way the widgets are going to work is in review still. Commit is also for
Matt for his proposal/paper on topic.
Some notes regarding this project;

- no life updates (on mouse over) like 3DS, I think that's neurotic
- on click, dominant axis changes to theme defined "Transform" color, other axes disappear, like maya
- manipulater size is fixed preset, independent zoom.
- manipulator follows selection, and is located based on 'around' mode

Unresolved;

- in maya, when you select 2 or more objects, the manipulator draws on the 'active' object, also interesting
- what to do with G,R,S hotkeys? It could switch the manipulator "mode"...
- header button/menu for manipulator mode?

fixed example of use the GetScreenInfo
.

Needed to normalise the axis orientation matrix.
This fixed the scaling bug intrr and LetterRip reported.

Ack, typo in previous commit, bugfix for confusing edge selection. Passed
a face pointer to edge function... tsk tsk!
