BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Without this clang-format may wrap them onto a single line.

For clang-format not to wrap definitions.

Helps separate variable names from descriptive text.
Was already used in some parts of the code,
double space and dashes were used elsewhere.
|
|
It is very commonly needed in loop conditions to check if
the items in the heap are good enough to continue.
|
|
Some of these API's can have 3D versions, explicitly name them 2D.
|
|
- When returning the number of items in a collection use BLI_*_len()
- Keep _size() for size in bytes.
- Keep _count() for data structures that don't store length
(hint this isn't a simple getter).
See P611 to apply instead of manually resolving conflicts.

Recent addition of 'reinsert' didn't match logic for ghash API.
Rename to BLI_heap_node_value_update,
also add BLI_heap_insert_or_update since it's a common operation.

Improves performance for high poly meshes,
~70% faster for decimate, only ~10% for beautify.

Was using an edge hash for triangle -> edge lookups,
updating triangle indices for each edge-rotation.
Replace this with half-edge which can rotate edges much more simply,
writing triangles back once the solution has been calculated.
Gives ~33% speedup in own tests.

This allows to have different macro headers without them sharing
similar names to regular C modules.

no functional changes.

Own error in recent decimeter commit
|
|
|
|
|
|
This allows the error threshold for calculating the optimized location to be much lower.
Resolves visible artifacts w/ 1m-tri happy-buddha example.
|
|
|
|
This can't be avoided completely, however the threshold used can be much lower.
|
|
|
|
Support for decimating while maintaining symmetry on a single axis.
|
|
|
|
Can be useful to apply more extreme weighting
|
|
Add slider to adjust the influence of weights relative to geometry distortion.
This allows subtle influences to be applied - without drastic changes in behavior.

Since using doubles to calculate cost,
using topology fallback cost isn't needed as much.
|
|
Float precision was causing problems for decimate,
small faces that create a nearly flat surface were detected as having no 'cost' to collapse.
|
|
Previously decimate on flat areas of a mesh would more or less randomly collapse edges.
(giving bad topology).
This commit includes a topology 'cost', so smaller edges on flat surfaces collapse first.
|
|
Created overlapping faces in T44780

|
When calculating quadrics, using the first-vertex isn't correct.
|
|
Also add depsgraph & physics

Was breaking windows compile, reported by bdancer over IRC, thanks.
Also, quite some annoying 'unused vars' warnings (debug-only vars).
|
|
`CustomData_bmesh_interp_n` was expecting the 'dest' arg not to have its offset applied.
This was a bit confusing since the source args have it applied,
and in some cases we only have the destination with the offset.
|
|

Turned out there was still quite a few cases were indices were set dirty,
but elem_index_dirty was not tagged accordingly (mostly for BM_LOOP,
but a few others as well). So probably this crash was not the only one
hidden here.
Hopefully all possible cases were catched this time!
|
|
Opted to keep includes if they are used indirectly (even if removing is possible).

handling.
Most notably, BM_LOOP and BM_FACE index recompute should now be fully decoupled.
|
|
* 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.

also remove CDDM_Check, theres no need for it.
