previous code created faces with mixed face-flipping and could get very slow,
test with ~60,000 edges here hung my system for over 2min (didnt wait for it to finish), new code executes in about 1 second.
new code doesn't attempt to flip faces correctly, its quite involved to do so, especially when the new faces are not created adjacent to eachother.
so simpler to calculate normals afterwards.

This disables crazy adaptive sampling happening in diagonal direction.
This still gives some doggyness, but it's much less dramatic now,
and behavior is pretty damn the same as EWA filtering when rendering
textures with Blender Internal.

Problem is that the read/write buffer operations only work with actual
image inputs. If a singular value is used as group input no actual
buffer will be created, the write operation does not schedule any chunks
and the ReadBufferOperation subsequently returns zero
(MemoryBuffer::read).
The fix uses the (0,0) resolution to detect single value input of the
WriteBufferOperation. The actual resolution is then clamped to (1,1) to
ensure we have a single pixel to store the value in. A m_single_value
flag is also set, so we can reliably distinguish this from genuine image
resolutions without having to check m_width/m_height later on.
The ReadBufferOperation copies this flag from the associated
WriteBufferOperation and if set will always return the single value from
pixel (0,0).

us unimportant, since append steps over the whole list each time.

the subset version of the function checks if any faces has all its verts in the given array.
also made some additions to linklist functions (arena and pool versions of append).

In fact, there's no need to get float buffer at all,
conversion could be done in pixel processor level
after interpolation.
It might give slightly worse interpolation results
(which i'm not sure would be visible by eye) but
it gives more than 2x speedup on my laptop on node
setups used for warping image.

This commit includes all the changes made for plane tracker
in tomato branch.
Movie clip editor changes:
- Artist might create a plane track out of multiple point
tracks which belongs to the same track (minimum amount of
point tracks is 4, maximum is not actually limited).
When new plane track is added, it's getting "tracked"
across all point tracks, which makes it stick to the same
plane point tracks belong to.
- After plane track was added, it need to be manually adjusted
in a way it covers feature one might to mask/replace.
General transform tools (G, R, S) or sliding corners with
a mouse could be sued for this. Plane corner which
corresponds to left bottom image corner has got X/Y axis
on it (red is for X axis, green for Y).
- Re-adjusting plane corners makes plane to be "re-tracked"
for the frames sequence between current frame and next
and previous keyframes.
- Kayframes might be removed from the plane, using Shit-X
(Marker Delete) operator. However, currently manual
re-adjustment or "re-track" trigger is needed.
Compositor changes:
- Added new node called Plane Track Deform.
- User selects which plane track to use (for this he need
to select movie clip datablock, object and track names).
- Node gets an image input, which need to be warped into
the plane.
- Node outputs:
* Input image warped into the plane.
* Plane, rasterized to a mask.
Masking changes:
- Mask points might be parented to a plane track, which
makes this point deforming in a way as if it belongs
to the tracked plane.

This is mine and Keir's holiday code project :)

This adds a new Euclidean resection method, used to create the
initial reconstruction in the motion tracker, to libmv. The method
is based on the Procrustes PNP algorithm (aka "PPnP"). Currently
the algorithm is not connected with the motion tracker, but it
will be eventually since it supports initialization.
Having an initial guess when doing resection is important for
ambiguous cases where potentially the user could offer extra
guidance to the solver, in the form of "this point is in front of
that point".

OpenEXR libraries shall go after OpenImageIO,
otherwise it'll fail to find symbols needed
for OIIO.

* FIX: selecting bookmark or recent file caused UNDO push, also caused issue with the 'Open' and 'Cancel' buttons being grayed out.
Reported by Sergey Sharybin in IRC, many thanks.

Creating new splines via Python API didn't take
curve dimension into account.
Now adding new splines will set 2D/3D flag for
spline according to curve's dimension.
|

This is useful for benchmark tests, to make CPU cache
utilization as good as we could with current design.

Currently this is only for the Python API. The logic brick will be updated in a future commit.

Now sounds that stopped playing but are still kept in the device can be differentiated from paused sounds with this state.
This should also fix the performance issues mentioned in [#36466] End of SequencerEntrys not set correctly.
Please test if sound pausing, resuming and stopping works fine in the BGE and sequencer, my tests all worked fine, but there might be a use case that needs some fixing.

This is getting confused, why bevel is handled different
for 2D and 3D curves?
Anyway, made bevel work for 2D case nice again, but it's
probably nice to unify 2D and 3D cases.

Fix: to swap the drawing order for the warp mesh polygon
The code was drawing CW instead of CCW.
It would work in some cases where the drawing flags would allow for the
back faces to be visible.
More specifically the alternative fix were:
glDisable ( GL_CULL_FACE );
glFrontFace( GL_CW );
Bug originally reported in the small_planetarium mailing list.
This bug fix was a comissioned job by a group who prefer not to be
credited. Thanks regardless.

array reallocation with alloca.
fix for error increasing the face tag count when the face might not be created.
|
|
|
|
also simplify for loops.
|

Needed correct quat for first point as well.
Maybe it's time to refactor make_minimum_twist function a bit..

- allow negative index values.
- error when invalid index value are passed in.
- remove last item if no index argument is given.
also change behavior to remove the material slot, it was only clearning by default but the list length remained the same.

function was accessing the psys->frand random number array, but since the particle modifier is disabled this array does not get
initialized. Added a sanity check to skip disabled particle systems in BI render. (why wasn't this done before?)
