Simple child hairs don't have a face index number assigned, so the
call to dm->getTessFaceData(dm, num, CD_MFACE) would cause a crash. To
work around this, UV and normal vectors are copied from the parent
hair.
I've also removed an unnecessary call to dm->getTessFaceArray(dm);

Not much to add here, except that it needs the scale of its MVP matrix
to be taken into account here...

The function doesn't return whether the object is a shape at all, since
it also returns true for camera objects (and soon also for empties). It
returns true when objects of this type can be exported to Alembic at all.
This is now reflected in the name.
Use new 2D dashed line shader in 3DView camera view.
Note that this also involved converting UI_draw_safe_areas() to this
dashed shader, which means it cannot be used anymore with other shaders.
Part of D2647.
Even though in some cases this does not seems useful, in others (like
zommed 2D views) we have to correct MVP matrix scaling to get fixed
dashes size.
Note that we could do that differently (commented about it in shader),
would also have been cleaner to extract that MVP scale from within the
shader, but there does not seem to be a way to initialize uniform values
from within a shader, and would rather avoid recomputing the scale for
every run (especially since 3DViewport does not need it e.g.).
Part of D2647.
That still not ideal, but so be it. IS_VIEWPORT_LEGACY should be
removed anyways, this is code from pre-draw manager and the
"modern viewport" as well as legacy will go away entirely once the draw
manager is feature complete.
Selection code needs to iterate over DEG_OBJECT_ITER otherwise we won't
get modifiers, dupli objects, ...
Also make selection respect selectability flag.
Review by: Sergey Sharybin
- use DRW_engine prefix for engine types.
- use engine suffix for files that define a draw engine.
- remove engines from include path (they're only referenced once)
- Use uniform color world for the world probe.
- Refactored the Fresnel expression to be better with Area Lights.
- Squared the roughness for default materials.
Needed to remove old draw code entirely.
Object mode selection support, pose and armature still need to be added.
Enabled when 'use_modern_viewport' is set.
- Added New Batch cache routine to get the split mesh for each material. (optimization needed)
- Did some shader modifications to create default_frag and support a somwhat correct fresnel for lamps (to finish)
Otherwise if we create a new collection, and drag a collection into it we either
get a crash, or at the very least we dont get the visibility flags correct.
This is part of the new draw manager design. Any engine (even clay, eevee, ...) should be able to draw to the viewport, as well as render to an image directly.
Changing the API names to conform to that.
