A new option for Font/Text objects vertical alignment:
* Top Base-Line (current mode)
* Top
* Center
* Bottom
The Top is the equivalent as the Top-Baseline with an empty line at the begin of the
text. It's nice to have this option too though, since if we are driving
the alignment via Python we don't want to add extra lines to the text
only to accomodate to the desired vertical alignment.
The Center and Bottom are as intuitive as their name suggest.
When working with text boxes, the vertical alignment only work for
paragraphs that are not vertically full.

BM_face_split_edgenet wasn't correctly detecting boundary vertices to walk over,
since vertices may be attached to boundary edges not part of the newly created face.
rB046adde64f16 was actually pretty useless (and broken), since issue ends up not being
in binary search code, but in generation of the 'summed weights' array used to distribute
particles over mesh items - looks like very small weights could lead to null accumulated
weights, wich was breaking binary search.
Fixed simply by adding a minimal, non-zero weight for mesh items to be allowed to emit particles.
Hopefully we are done with this distribution mess!
It is not possible to use a set split by name as valid input to
check_node_input_traversed - it needs a complete set of all nodes visited so
far. On the other hand, the merge comparison loop should only check nodes that
were not just visited, but found unique. This means that there should really be
two separate data structures.
Without the fix, check_node_input_traversed actually never returns true, so
only nodes without any inputs are processed.
For non-branched path tracing with a GTX 960 and CUDA 7.5, this gives a small reduction
in stack usage but mainly: 8% faster render on BMW, 5% on pabellon, 13% on classroom.
This is an initial commit for half texture support in Cycles.
It adds the basic infrastructure inside of the ImageManager and support for these textures on CPU.
Supported:
* Half Float OpenEXR images (can be used for e.g HDRs or Normalmaps) now use 1/2 the memory, when loaded via disk (OIIO).
ToDo:
Various things like support for inbuilt half textures, GPU... will come later, step by step.
Part of my GSoC 2016.
Some area were still not in sync with readfile.c, now should be better.
Note that readfile.c has been used as référence here re us refcounting,
not sure how accurate it is, time will say :|
Optimization in binary search could lead to equality instead of expected strictly greater than value.
Harmless but noisy, and better be strict here.
reported by sergey on irc (with koro cycles benchmark file), thanks.
In some cases when:
* the viewport was in the camera mode
* the camera was ortho
* the view was not fitting (as oppose to use HOME)
region_2d_to_origin_3d would misbehave (and consequently region_2d_to_location_3d).
Sample addon to test it:
```
import bpy
from bpy_extras.view3d_utils import (
region_2d_to_location_3d,
)
from mathutils import (
Vector,
)
class MoveXYOperator(bpy.types.Operator):
"""Translate the view using mouse events"""
bl_idname = "view3d.move_xy"
bl_label = "Move XY"
@classmethod
def poll(cls, context):
return context.object
def modal(self, context, event):
if event.type == 'MOUSEMOVE':
self.move(context, event)
elif event.type in {'LEFTMOUSE', 'RIGHTMOUSE', 'ESC'}:
return {'FINISHED'}
return {'RUNNING_MODAL'}
def invoke(self, context, event):
if context.space_data.type == 'VIEW_3D':
self.ob = context.object
context.window_manager.modal_handler_add(self)
return {'RUNNING_MODAL'}
else:
self.report({'WARNING'}, "Active space must be a View3d")
return {'CANCELLED'}
def move(self, context, event):
xy = region_2d_to_location_3d(
context.region,
context.space_data.region_3d,
(event.mouse_region_x, event.mouse_region_y),
Vector(),
).xy
self.ob.location.xy = xy
def register():
bpy.utils.register_class(MoveXYOperator)
def unregister():
bpy.utils.unregister_class(MoveXYOperator)
if __name__ == "__main__":
register()
```
