Blender Git Loki

LANPR: use "master style" instead of following contour style.

GPENCIL: use copy_v3_v3 for gp points.

[Fast import/export] Added NURBS export. Previous commit added path mode

ProfileWidget: Profile fill display added. Uses triangulation from Polyfill_2d.c
to build triangles that make up the profile's area. A different filling method from
the CurveMapping widget is necessary because the profile's path is not necessarily
a mapping function.

Set up OpenXR views and spaces for drawing

Using a dummy identity pose at {0, 0, 0} to start with. This should
later use the current viewport position & orientation I guess.

Also adds function to set a draw callback. There's quite some OpenXR
related stuff to be done before and after drawing anyting, as well as
before and after drawing each view (eye). Quite some info would have to
be exposed to WM to let it manage drawing. So I think using a callback
called from GHOST_Xr to draw each eye instead is a good way to go.

VR session currently crashes after opening. Seems to be related to
blocking frame wait call. I'm not too worried about that though, might
disappear once OpenXR frame sync functions get proper timing info
passed.

Mantaflow: More manta / smoke renaming and added some sanity checks for the adaptive domain

[Fast import/export] Bug fixing, added and fixed UI

[Fast import/export] OBJ exports materials and animations

Bring back wm_xr.c for higher level XR functions

Execute necessary OpenXR frame timing calls

LANPR: make format

LANPR: two step chaining, need a toggle for switching 2d/3d space priority.

LANPR: Fixed modifier read pointer error by providing foreachObjectLink() callback.

LANPR: modifier controlled stroke generation is working. (only manual)

LANPR: feature line modifier manual update

Correctly destruct swapchain on shutdown

Create graphics binding specific swapchain images

Following the OpenXR SDK's example code very closely here. We have to do
some nasty converting of graphics binding specific image vectors to
generalized base ones. The SDK's approach seems like a good way to go
about this.

Use abstract class/interface for generalized graphics binding operations

Rather than having switch case blocks throughout the session code, give
binding operations an own interface with dedicated implementations.

Fix error causing sessions to not start correctly

With this, the Windows Mixed Reality Portal finally pops up when
starting the session. That is how it's supposed to work. After it's
initialization phase all you see is black. That's expected too as we
don't send anything to the device yet.

OpenXR swapchain creation

Nothing special to say. Just calls needed OpenXR functions to create
swapchains. Swapchain images are not created yet.

Interestingly, the Windows Mixed Realtiy portal now pops up when closing
Blender after having created a VR session. So we're getting closer ;)
