This commit adds some first building blocks for the two operators to work modally based on mouse input. To make their function easier, two hotkeys are introduced, Ctrl+B for bevel and I for inset.
TODO:
After discussion with Campbell, we would like to add scale-style line indicators for the operators. This is already done for transform operators but a new interface for mesh operations may have to be written using pieces from that code since, strictly speaking bevel and inset are not exactly "transform" operators.
Also, a better input method for inset is needed and more options exposed. The method implemented right now uses mouse move for thickness and ctrl-mouse move for depth. These are calculated using the distance of the selection center in screen space and the mouse position. While that may work and prevents abrupt changes in values when switching from thickness tweak mode to depth tweak mode, it limits the magnitude of values that can be put into the tool especially in small or large scale.
Alternatives until a better method is written include:
* use relative offset (works but may give strange results)
* tweak manually after the operation.
Added four new functions as shortcuts to creating GHashes that use the
standard ptr/str/int/pair hash and compare functions.
GHash *BLI_ghash_ptr_new(const char *info);
GHash *BLI_ghash_str_new(const char *info);
GHash *BLI_ghash_int_new(const char *info);
GHash *BLI_ghash_pair_new(const char *info);
Replaced almost all occurrences of BLI_ghash_new() with one of the
above functions.
Now only one operator. Same options for vertices, edges and faces (so adds edges sorting, and some options to vertices sorting).
Face sorting should behave as previously. However, XSortVerts won’t pack anymore selected vertices at the begining of the vert array (as it used to), if you want such behavior you’ll have to first run SortElements with Selected action.
Also added bug ref I forgot in r46354 (armature.c).
this is in fact 2 bugs.
- unselected edges between 2 faces that were joined didnt get removed.
- in face mode, edges and verts at the boundary of the selection would get incorrectly dissolved.
also quiet float/double promotion warning.
- makes wireframe from faces.
- options similar to inset (even offset, relative scale)
- copies face settings and loops (uvs, vcolors)
- optionally replaces the existing geometry.
That whole "element re-arrange" area could use some love, though (e.g. make a single vert operator with more options, as faces; and make faces work in edit mode, probably no more reasons to switch to object mode?). Post-release TODO, anyway.
Also spotted a glitch in BLI_rand code, imho, which makes first element of an array not guarantied to be shuffled by BLI_array_randomize()... No correction though, as this might/would affect other parts of the code!
This commits adds a new function which can remap vertices/edges/faces of a BMesh in a new given order:
void BM_mesh_remap(BMesh *bm, int *vert_idx, int *edge_idx, int *face_idx)
- dont do name based object lookup to find the object for a mesh undo state (possibly object is renamed inbetween undos which would crash)
- remove some todo comments for things that are working as they should.
