Improved accuracy of the eraser a bit. Now it does a boundbox test first before trying to erase strokes, which means that other (rather unrelated) strokes are less likely to be affected as well.
Other methods could easily be supported in the future. The method now works as planned for the contour style. For style modules with Python shaders, there still is a problem that I will fix right away.
With this patch, only sensors that are connected to
active states are actually registered in the logic
manager. Inactive sensors won't take any CPU,
especially the Radar and Near sensors that use a
physical object for the detection: these objects
are removed from the physics engine.
To take advantage of this optimization patch, you
need to define very light idle state when the
objects are inactive: make them transparent, suspend
the physics, keep few sensors active (e,g a message
sensor to wake up), etc.
This commit introduces the ability to erase strokes. Admittedly, the code for this is not totally stable yet, and doesn't always produce optimum results. I'm committing now for backup purposes.
It currently uses the lasso code to check whether segments of the strokes (a segment occurs between two recorded points) occur inside a region defined by the 'eraser' stroke, or any intersections it makes with the 'eraser' stroke.
There are multiple ways to erase strokes:
* With 'Draw Mode' on, use RMB-drag to erase
* With a tablet, use the 'eraser' end of the stylus
* Hold the Alt Key, and use the 'selection' mouse-button (i.e. LMB if mouse-button swapping is on, RMB otherwise) to erase. For this one, this is necessary to avoid overriding the view-rotation hotkey combo for 2-button mice!
Todo:
* 3d-strokes are not correctly mapped back to screen-space for sampling yet
* Drawing of eraser strokes is still not distinctive enough
* After running a few times, may cause stack corruption/segfaults, so be careful!
== Bugfixes ==
* Grease-Pencil Onion-Skinning works again. Onionskining was being supplied the wrong frames, and the alpha factor was still the old one used for 0-255 ranged colour values
This includes...
- Renaming dLoc and dRot as Loc and Rot ( as well as changing the tooltip to location and rotation ). dLoc and dRot are programming terms, not user terms.
- Placing Loc and Rot as the two initial shown values, so that the physical ones are all shown together.
I also changed it so that only Loc and Rot are shown in the UI, unless the object is Dynamic ( as the other values only make sense if it is dynamic ).
These are just a few simple changes, that should make a lot of difference to users when learning how to use the GE.
--------------------------------------
Things I'd *really* like to do to this, when I get a chance to code Blender again ( hopefully in a few days time, after I have finished teaching on the GE course )...
Color / Colour tint the X,Y and Z entry boxes as slightly red, green and blue, to reflect the colour of the axis / transform gizmo
...or...
Just show X,Y and Z labels above all of the values.
Getting to grips with the whole XYZ thing is very confusing for users, esp when they are presented with 6 x 3 entry boxes.
There existed two options to copy only the mass, and only the damping, but no option to copy all of the physical attributes.
This patch adds in this option, right under the Mass and Damping listings.
This one deals with the very small default clipend value ( 100.0 ) when pressing P to run the GE from a non-camera view. ( ie if the user zooms out a bit from the default box area, the box will get clipped out of view, so it's a WFT from the user )
To see what this fixes, load up Blender default scene, go into perspective, and press P. Everything looks grand. Now, zoom out until the box is about 10 pixels high, and press P again. The box will disappear / be clipped out.
I've set the clip end to the maximum ( 5000 ) as defined in Camera.h.
This should be suitable for inclusion in 2.47 branch also.
Retag subgraphs when merging, to prevent loops
Mark missing up link in multi resolution as NULL
Ignore hidden vertices when propagating weight between islands
=======================================
Alpha blending + sorting was revised, to fix bugs and get it
to work more predictable.
* A new per texture face "Sort" setting defines if the face
is alpha sorted or not, instead of abusing the "ZTransp"
setting as it did before.
* Existing files are converted to hopefully match the old
behavior as much as possible with a version patch.
* On new meshes the Sort flag is disabled by the default, to
avoid unexpected and hard to find slowdowns.
* Alpha sorting for faces was incredibly slow. Sorting faces
in a mesh with 600 faces lowered the framerate from 200 to
70 fps in my test.. the sorting there case goes about 15x
faster now, but it is still advised to use Clip Alpha if
possible instead of regular Alpha.
* There still various limitations in the alpha sorting code,
I've added some comments to the code about this.
Some docs at the bottom of the page:
http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/
Merged some fixes from the apricot branch, most important
change is that tangents are now exactly the same as the rest
of Blender, instead of being computed in the game engine with a
different algorithm.
Also, the subversion was bumped to 1.
To make it work, I had to:
- update Operators to include all of its methods in the Python API
- redefine the Freestyle modules as local classes, allowing predicates to support the __call__ method (I found out that Python does not allow modules to be callable). The API is defined in the new freestyle_init.py file.
- remove all references to former Python Freestyle API (located in source/blender/freestyle/python/, under the Freestyle.py file) and replace it with the new API file.
- normalize all constants related to the Nature class
- redefine the logical_operators.py file so that AndUP1D, OrUP1D and NotUP1D would be subclasses of a UnaryPredicate1D subclass having a operator() implementation. Using UnaryPredicate1D as a superclass would somehow prevent calls to the operator(). For the time being, I chose ContourUP1D (even though it does not really matter which subclass it is, since the __call__ method is redefined in all of these classes). I will implement this classes in C++ to get rid of the problem altogether.
- turn off a few classes that somehow are not well recognized (Noise, Curve...). I will reenable them later once I understand what's going on.

Quite a few modifications were made to finish the API:
- Freestyle's SConscript was modified to catch all files within the intern/python directory, allowing integration of future shaders implemented in C++.
- the Operators class was ported, with a special care of making its methods static (using the METH_STATIC flag in the tp_methods method definitions)
- all of the type-checking functions [ BPy_[class name]_Check(obj) ] were changed to allow subclasses to be seen as that type too: instead on looking at the ob_type value, the PyObject_IsInstance function is used.
- all of the iterators can now retrieve the object pointed to by the operator, using the getObject() method. A directedViewEdge pair is returned as a list of the two elements in the pair.
- all of the style modules were copied to a style_modules_blender/ folder and were modified to use Freestyle as a Blender's submodule. IntegrationType and MediumType was also integrated (for example, changing MEAN to IntegrationType.MEAN).
Testing now begins. If everything works correctly, I'll move on to lib3ds removal right away.
There is just one more class remaining to port (and probably the most important): Operators. After that, I'll be able to test whether Freestyle functions well without SWIG.
- Takes less than half the time to format a full document
- Where possible only the required lines are re-parsed when text is changed (was the whole file, for every key press!)
- Memory is allocated in one place only (there were all sorts of problems here)
- Should be easily extensible for other scripting languages
- Lots of comments to make it very easy to follow / change
- def and class are now properly coloured. They had a theme colour but the checks didn't work.
Bone-locking should only be set if the bone (and not its parent/children) are selected. Transposition error from the patch (I had to manually apply as there were some oddities about the patch file).
The pasting code for text-buttons (when hovering over the button), was incorrectly using the drawstr (i.e. the string that is displayed in the text-button, and includes the 'name' of the button) as the old value. This meant that the renaming code could not correctly detect matches to rename.
This bug-report revealed a critical error made in the menus for Constraints Owner/Target spaces. It seems that the wrong values have been used for 'pose space' and 'local with parent' space. This has now been rectified, so that old rigs won't break (just that the labels will be a bit different).
