Line styles now have a set of new options for rearranging the stacking order of lines.
This gives artists more control to determine which lines should be drawn on top of others.
Two available sort keys are the distance from camera and curvilinear 2D length.
Since the distance of a line from camera may vary over vertices, another option called
integration type is used to compute the sort key for a line from the values computed at
individual vertices. Available integration types are MEAN, MIN, MAX, FIRST and LAST
(see the tool tips for more detail).
It makes code more tidy (avoids having to call invalidation on a myriad
places). Also makes sure other invalidation cases (some mesh change,
e.g.) work as expected.
Don't use a dedicated node layer but use temporary int layer instead.
Works like a charm as long as we are careful resetting the layer when
needed (after pbvh clearing and always after bmesh has been filled in
undo)
Tip by Campbell, thanks!
This commit makes it so CameraIntrinsics is no longer hardcoded
to use the traditional polynomial radial distortion model. Currently
the distortion code has generic logic which is shared between
different distortion models, but had no other models until now.
This moves everything specific to the polynomial radial distortion
to a subclass PolynomialDistortionCameraIntrinsics(), and adds a
new division distortion model suitable for cameras such as the
GoPro which have much stronger distortion due to their fisheye lens.
This also cleans up the internal API of CameraIntrinsics to make
it easier to understand and reduces old C-style code.
New distortion model is available in the Lens panel of MCE.
- Polynomial is the old well-known model
- Division is the new one which s intended to deal better with huge
distortion.
Coefficients of this model works independent from each other
and for division model one probably want to have positive values
to have a barrel distortion.
Tessellated split normals CDlayer had no swap func, hence ugly little test_index_face()
could not rotate its values correctly when rotating tessellated faces...
Extra-reported in T39735.
The problem here was that animation buffers got initialized with zeros in the beginning for unknown parts. Now it gets initialized with the first known value.
The bug's result was that the animation of the pitch started with 0 on first playback and thus any seeking while the pitch is zero resulted in seeking to the beginning.
Since this is now pretty much the de-facto "minimum distance between keyframes",
we might as well expose this in this header so that other places which need similar
thresholds can perform similar checks (needed for my next commit)
Root of issue is probably in AUDASPACE itself (or even in OpenAL?).
Issue not present with SDL backend, only OpenAL afaik.
For now, workaround in Blender is to call seek twice when starting play
(not needed when resuming from pause).
- BLI_ghashutil_strhash_n takes string length, to avoid terminating the string before hashing.
- BLI_ghashutil_inthash/uinthash take ints, to avoid casting to (void *)
This also showed up incorrect use of inthash, which was using a pointer.
* Merely a re-implementation of core split algorithm for BMesh, taking advantage of topological data available.
* This code needs valid loop indices, so added BM_LOOP support to BM_mesh_elem_index_ensure() & co.

* Add a new calcLoopNormals function to DerivedMesh struct, and implement it for CDDM and CCGDM (subsurf).
EditDerivedBMesh (edit mode DM) only gets a dummy one in this commit.
* Add a tessellated version of CD_LOOPNORMAL layer (CD_TESSLOOPNORMAL), with relevant code to handle it
(tessellation, rna access, etc.).
* Change auto_smooth options of Mesh (angle now in radian internaly, and toggle is now used to enable/disable
split normals in DM creation process). Note BI render code is not touched here, hence its behavior regarding
this option is now incoherent, will be addressed in a separate commit.

This gives a huge speedup gain for cases when you've got
rather huge markers on a byte images.
Done by skipping IMB_float_from_rect()/IMB_rect_from_float()
for such cases. We can sample the buffers without color space
conversion.
The variables are considered invalid unless DM_update_materials is
called prior to use. Only use case currently is
mesh drawing. This helps with excessive allocation on the stack during
GPUObject creation, but may help elsewhere in the future as well.
