The view vector was not being calculated correctly. Shamelessly rip off
correct transform to object space from projective texture painting code.

and undo buffers.
When we have smooth shading we must not only update the unique vertex
normals.

* fill-holes operator now takes advantage of new edge-net fill, works in many more cases then it did before.
* face-create that uses edge-net now initializes the normals based on surrounding geometry, only running normal calculation if there are no connected faces for a reference.

New features:
* Bump mapping now works with SSS
* Texture Blur factor for SSS, see the documentation for details:

Work in progress for feedback:
Initial implementation of the "BSSRDF Importance Sampling" paper, which uses
a different importance sampling method. It gives better quality results in
many ways, with the availability of both Cubic and Gaussian falloff functions,
but also tends to be more noisy when using the progressive integrator and does
not give great results with some geometry. It works quite well for the
non-progressive integrator and is often less noisy there.
This code may still change a lot, so unless you're testing it may be best to
stick to the Compatible falloff function.
Skin test render and file that takes advantage of the gaussian falloff:

* Forgot to remove RNA/DNA in r59043. No need to keep this here, we never used it in Trunk.

- use single inlined lookup function.
- move comments into source.
- pack iterator vars more efficiently.

ghash/edgehash.
the outliner does this intentionally, so add a flag to allow this situation optionally.
|
|
- optimize BM_face_exists_overlap_subset(), dont check faces smaller then the vert array, don't initialize overlap flag unless its needed.
- BM_face_exists_overlap had incorrect check (currently function is unused so no harm done)

This is done by fixing logic for finding the first unused element in treehash.
The blend file from [36486] also exposes a memleak, but it should be addressed separately.

This will make transitions from older versions of Blender easier since VSYNC_ON
will be the default. This could have been changed in a do_version, but the vsync
code has yet to see an official release, so I figured this would be a bit nicer.
Also, this makes VSYNC_ON the default for new scenes as well.

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.
Some video tutorials are available:
- Coder video: http://www.youtube.com/watch?v=vISEwqNHqe4
- Artist video: https://vimeo.com/71727578
This is mine and Keir's holiday code project :)

* 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 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.

Make it so mpath is not shared between several bones now.
Fix suggested by Joshua Leung, thanks!

also remove unused transform defines.

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..
|
|
support this.
