Getting ready for a Gawain API change...
Part of T49043
|
|
I converted all other files a day or two ago; this file was part of a recent merge.
|
|
All line & point drawing is responsible for setting its own state (as of January 2016) making this redundant.
|
|
Single quads are drawn as a TRIANGLE_FAN, with 4 verts in the same order.
Multiple quads now use PRIM_QUADS_XXX and will need further work. Only 8 places still use this.

Bug crawled in via 2944438e9a276e48d7eabb5bb88ecec9b2f1e7dc as part of custom manipulators.
|
|
We concatenate #defines and #extensions into these, and can count the max string lengths needed. 256 is enough to hold today's strings; we can adjust later if needed.
|
|
Follow-up to 204e067111af9346fccea9981a0a7962ec8ef906 which coverted manipulators' legacy GL matrix calls to new ones.

When WITH_LEGACY_OPENGL = OFF.
This is our final target for Blender 2.8, all previous versions will be dropped in the future. GLSL 3.3 is richer so we don't require as many extensions.
|
|
Kudos to Germano Cavalcante for spotting the issue, the real fix is to pass SL to the function though

It's possible that cancellation occured between the creation of the reader
and the creation of the Blender object, in which case reader->object()
returns a NULL pointer.
|
|
BKE_libblock_free_us() was called on the object data, which decrements
its user count, after which the same function was called on the object,
which decrements the user count of the object data again. This double
decrement was too much.
|
|
This used to be a separate pass
|
|
This was necessary, but was only mentioned at gather_object_paths (which
I didn't see earlier). That's now also fixed.
|
|
Original code from @Severin with changes from @dfelinto & @hypersomniac.
This doesn't cause many functional changes
besides using new transform manipulators.

More explicit, easier to read & understand.

This fixes T51143.
gl_ClipDistance is part of GLSL version 1.3 but Mac is stuck on 1.2 for now.
This workaround uses GPU_SHADER_3D_UNIFORM_COLOR for the entire rotation widget, ignoring any clipping plane. The CLIPPING shader only works on GLSL 1.3+ so I removed its 1.2 cruft.
A legacy implementation using gl_ClipVertex might be possible, but is not worth the effort. This problem (and workaround) goes away when all platforms move to 3.3 core profile.

Was popping out the bottom of the stack.

changes:
- exact vertex count
- take bool (filled vs outline) instead of GLenum
This function has some flexibility that is not currently used. I left that in.
|
|
Each function takes a bool (filled vs outline) and a color. We already had multiple ways of passing color in; these are still here. Special variant for anti-aliasing.
- took GLenum out of interface
- removed UI_RB_ALPHA flag (only one place really used it)
- use exact vertex count
- removed redundant state changes (BLEND, LINE_SMOOTH)

This introduces a new CMake option - WITH_LEGACY_OPENGL. Without this option
things may not draw perfectly, however, we should soon be able to build with
OpenGL core profile.
The matrix-related api calls are (still) not handled here (glTranslate, ...).
There seems to be no consensus on whether to make this build option the
default. We can talk about this later. For now two things are the
priority:
(1) To get rid of deprecated calls when WITH_LEGACY_OPENGL is ON
(2) To make core profile work for Mesa/Mac when WITH_LEGACY_OPENGL is OFF

Many thanks for Sergey Sharybin for the help.

Previously, a GHash was used to store a flattened mapping of parent
information based on the Alembic hierarchy, and then that hash was used to
set parent pointers on Blender objects. This resulted in errors and
some duplicate objects. The new approach stores parent pointers while
traversing the Alembic hierarchy, which means that there is much more
information about the actual context of the Alembic object itself,
producing a more stable import.
|
|
|
|
and more:
Also replaced the bool param "to_yup" with "AbcAxisSwapMode mode", so that
it's more explicit that axes are swapped.
Also added unittests for create_swapped_rotation_matrix.
|
|
There was a problem with parent-child relations not getting set up
correctly when an Alembic object was both the transform for a mesh object
and the parent of other mesh objects.

convert_matrix() now only converts from Imath::M44d to float[4][4] (taking
different camera orientations into account). Import-time scaling is now
performed by the caller.

This is not really supported with the new depsgraph.
