Some of these API's can have 3D versions, explicitly name them 2D.
|
|
Border and circle select wait for input by default.
This commit uses bool properties on the operators instead of
magic number (called "gesture_mode").
Keymaps that define 'deselect' for border/circle select
begin immediately, exiting when on button release.
|
|
Replace with operator type 'last_properties'.
Also use generic function for circle gesture properties.
|
|
Remove unneeded define, double allocations when increasing.
|
|
Wasn't obvious what this did at a glance.
|
|
Having gesture automatic free memory isn't practical if this
has it's own allocations.
Add option not to free userdata.
|
|
Replace iroundf with round_fl_to_int, add other types

Bitmap drawing is out-of-scope for a general math API,
move to BLI_bitmap_draw_2d.
|
|
Replace glDrawPixels w/ glaDrawPixelsTex

The basic shader needs to be temporarily disabled in this case.
Add macros for temp store/restoring the state.

The patch contains an implementation of the wide lines and the line stipple that is necessary for OpenGL upgrade.
For the implementation I have chosen the geometry shader because it required minimum changes for the wrapper calls and such implementation is the best for the "basic shader" architecture.
There are few shortcomings that can be corrected in future. They all are related to the fact that the lines in one strip are not connected with each other. So the stipple pattern is not continuous on the common vertex of two lines. There is also no continuity of form (each line is an independent rectangular).
But the advantage is that even outdated glBegin, glVertex work! Though with the above restrictions.
Continuity of form and stipple can be implemented with additional attributes, and it will require more changes in calls.
At the moment, the patch replaces calls for some "gestures". It works satisfactorily for "cross" or "rectangular" and not so good for "lasso" and "circle" due to the above-mentioned shortcomings.
Don't forget to set USE_GLSL to true for testing.

Instead of running the callback per-pixel,
pass the x-span to the callback.

2d pixel filling for drawing and selection.
|
|
|
|
* Color picker cursor was too small, and color cirle was not smooth enough.
* Border select gesture cross before first click did not reach to the border
of the window.
* Buttons were not drawing emboss properly (also for non-retina actually).
Note it doesn't draw entirely right for aligned buttons, but this was also
the case before it got broken.

speedup for BMesh ngons which never have holes and ensures predictable triangle count (totvert - 2), which is needed for pre-calculating array size.
|
|
- use DummyRNA_NULL_items to replace empty enums.
- replace calloc with malloc in copy_dverts since its copied over after.
- add wmGesture->userdata, so operators that use gestures have somewhere to store their own data (not used yet).
|
|
scanfill remove-doubles pass assumes ordered edges (as with curves), otherwise it can hang.
workaround this problem by skipping removing-doubles for mesh ngons, since this isnt such a common case as it is with curves and we can just not support it.

use where possible.

replace do prefix with do_ for bool vars.
|
|
- use bmesh iterator macros in more places
- rename scanfill variables (were using same names as mesh faces/verts which was confusing)
|
|
|
|
use for editmode ngon filling.

merge it didn't need to be) - now rendering uses its better if its threadsafe.

|
* made bmesh_structure.h function names more consistant.
* remove unused code in bmesh_structure.c
* removed 'Edge Flip' operator (missing from bmesh but looked into trunk feature and dont think its worth keeping).
* tagged some BMESH_TODO's
|
|
- copy & rename EditMesh stricts for use with scanfill (remove unused members)
