The bug T46099 no longer applies since the addition of `dist_squared_to_projected_aabb_simple`
Has also been added comments that relates to an occlusion bug with the ruler. I'll investigate this.
|
|
|
|
Some `UI_ThemeColor` calls were left in converted files, in some cases
because they were just overlooked, and in the case of text drawing,
because the new BLF color functions were not yet implemented at the
time of conversion.
Also converted one `drawcircball` call that was left in
transform_constraints.c

(and more Scene.base > SceneLayer.object_bases changes in transforma code)
|
|
(and replace more instances of BaseLegacy/scene->base with Base/sl->object_bases)
Still need mouse selection, box selection, and menu selection
Also, there is still a problem with BA_WAS_SEL, at the moment only the
objects centers are highlighted.

Design Documents
----------------
* https://wiki.blender.org/index.php/Dev:2.8/Source/Layers
* https://wiki.blender.org/index.php/Dev:2.8/Source/DataDesignRevised
User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.

`transform_snap_context_project_view3d_mixed` with `dist_px` NULL
|
|
There are still many places to fix. I'll miss the bright yellow!
This commit also uses the new BLF_default function where possible.
Part of T49043 since we call glColor less often.
|
|
Ray_start and ray_normal values were being ignored
|
|
Looks like `object_map` and `mem_arena` may be NULL sometimes...
Also, cleaned up function pointers declaration of Nearest2dUserData,
those were warning out in gcc. Please, *always* use typdef defined
prototypes for function pointers, it is sooooo much cleaner and clearer
that way. And easy to convert from compatible functions too.
|
|
DerivedMeshs and Bmeshs
Before it was informed the type of object in the `userdata`, and a same function ran between the types to obtain the coordinates of the vertices
|
|
Since the cache is created in one way or another, this flag is not really making a difference
More details here: D2496
|
|
The code looks for the closest element between its centers. In the case of islands, the center of each vertex is the center of the island.
The solution here is to skip the search for islands when the operation is translation
|
|
In obect mode, the rotation matrix need to be restored to the initial value if a snap point is not found
|
|
transformation
The problem was simple, just transform the global coordinates of t->tsnap.snapTarget to local coordinates.
(Some comments were added to the code)
|
|
Had mistakenly used 3D shaders for some 2D drawings...
Replaced those now.

Also converted ED_node_draw_snap from drawnode.c
Committing these together, as they are inter-dependent.

perspective view
Strangely this change does not affect the performance very much.
Suzanne subdividide 6x (ortho view):
Before:0.00013983
After :0.00013920
But it makes it easier to read the code
|
|
When the function that tests snap on multiple elements starts from the face and ends at the vertex, the transition between elements becomes much smoother.

considering the depth variation
Taking advantage of the area, the depth is decreased 0.01 BU to each loop to give priority to elements in order: Vertice > Edge > Face. This increases the threshold and improves the snap to multiple elements
|
|
Ruler only works right this way
The Ruler snaps to the element with the lowest depth.
|
|
The previous solution took arbitrary values to determine if the mouse was near or not to the Bound Box (it simply scaled the Bound Box).
Now the same function that detected the distance from the BVHTree nodes to the mouse is used in the Bound Box
|
|
points to active object
A simple confusion between enums: ~SNAP_NOT_ACTIVE~
|
|
Please doublecheck ED_transform_snap_object_project_ray_ex() is really
valid, it's weird to have extra arguments here unused.
|
|
This provides a slight improvement in performance in specific cases, such as when the observer is inside a high poly object and executes snap to edge or vertex
|
|
The bug would only be seen in terms of performance

Error reported by @tomjpsun
Patch D2491
|
|
Remove `BKE_boundbox_ray_hit_check` since it is no longer being used and can be easily replaced by `isect_ray_aabb_v3_simple`
|
|
The new `isect_ray_aabb_v3_simple` function replaces the `BKE_boundbox_ray_hit_check` and can be used in BVHTree Root (first AABB). So it is much more efficient.
|
|
Don't use CamelCase in functions and try to keep area affected first, and action last, in names
|
|
You need to make sure that ray_start is really far away, because even in the Orthografic view, in some cases, the ray can start inside the object
|
|
new struct `SnapData`
In order to simplify the reading of these functions, the parameters: `snap_to`, `mval`, `ray_start`, `ray_dir`, `view_proj` and `depth_range` are now stored in the struct `SnapData`
|
|
'BLI_bvhtree_find_nearest_to_ray' in transform_snap_object
Although the "BLI_bvhtree_find_nearest_to_ray" function is more practical than the generic "BLI_bvhtree_walk_dfs", it does not work to snap in perspective view. This makes it necessary to add "ifs" and functions that make the code difficult to understand

Took pieces from D2316 and D2359, changed a few more things.
- use new immediate mode
- use new matrix stack
- remove state push/pop

Avoids possible jumps when one is trying to do some really preciese tweak.
Quite striaghtforward change for mouse input initialization: take Shift
state into account. However, this will interfere with the axis exclusion
which is currently also uses Shift (the feature to move something in a
plane which doesn't have selected axis). This is probably not so commonly
used feature (nobody in the studio even knew of it) and the only downside
now would be that such a constrainted movement will become accurate by
default. That's easy to deal from user side by just unholding Shift key.

Things like `BLI_uniquename` had nothing, but really nothing to do in
BLI_path_util files!
Also, got rid of length limitation in `BLI_uniquename_cb`, we can use
alloca here to avoid overhead of malloc while keeping free size (within
reasonable limits of course).

This reverts commit 5aa19be91263a249ffae75573e3b32f24269d890 and b4a721af694817fa921b119df83d33ede7d7fed0.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.
