On certain linux, macOS environment, there is already a system
getopt. This often creates conflict when compiling filament.
Here we alias utils::getopt to either the system getopt (if
present) or third_party/getopt.
Fixes#7551
Enables the multiview implementation as the default for stereoscopic
rendering. Now all STE variants use the multiview path.
This change removes all CMake configurations, build scripts, and C++
preprocessors previously used for selecting stereoscopic rendering
modes. And, all shaders are now compiled for multiview.
The instanced rendering implementation is going to be removed. Note that
this commit only handles switching the default. The actual removal of
instanced rendering code will be submitted as a separate follow-up
commit.
BUGS=[470198472]
The commit 1747ae8f5a enfoces a correct
order for releasing resource. Fix the order to avoid crashes.
Make some samples to use the DEPTH32F format for better compatibility.
Some manufacturers don't fully support DEPTH24 on Vulkan. E.g., AMD
Radeon PRO W6400
Currently mLayerCount for RenderTarget is always updated to the number
of depth for attachments, which incurs unintended behaviors for some
types of textures. i.e., 2d array, cubemap array, and 3d textures.
Fix this by updating mLayerCount only for multiview use case.
BUGS=[369165616]
Clients can create a multi-layered render target that consists of array
textures, and use it as a custom render target.
A new sample app "hellostereo" demonstrates how to use this feature.
