* Re-organize Android Gradle files
Clean up our Gradle files, share versioning, etc. and prepare for
publication to sonatype.
* Use androix annotations for desktop
* Add samples as subprojects to root Gradle
* Fix build script
* Don't break when samples aren't compiled
* Better organize the Android Studio project
The C definition was changed to include METAL, moving NOOP further down.
The Java definition never caught up, making NOOP mean METAL and making the
real NOOP unreachable.
This patch puts them back in sync. Also, updated the Java comments to match
the comments from the C definition.
If spherical harmonics are not specified in IndirectLight (i.e.
omitted entirely), we instead use the roughness==1 LOD in the shader.
This produce much better results with absolute HDR environment, and
generally works better more often.
This is now the preferred solution.
For cases where spherical harmonicas are better or preferred, they
can simply be supplied as before.
Sometimes CMake decides to use the JNI bits included with XCode instead
of those from the installed JDK. The header files are located in different
directories. This does the proper include.
This new sample differs from "Hello Camera" in that it exercises all
three ways of using Stream. It also uses Canvas instead of Camera2 to
draw into the external texture. It shows two sets of stripes, one
animated using the shader and the other animated using Canvas. If the
two stripes are aligned, then the stream is perfectly synchronized.
Users can tap the screen to cycle between the three modes.
- we add an 'intensity' parameter that allows to control the strength
of the AO effect. This is useful for aesthetic reasons.
- the default intensity is now 2x that of before this change, which
makes the intensity parameter match AO papers this implementation
is inspired of.
- bias is now z-dependent, which reduces some self shadowing wrt the
depth.
Previously, Streams had two modes (native and texid), this adds a third
mode called "acquired", which allows for copy-free synchronized external
textures in OpenGL and paves the way for Vulkan.
The native mode is now deprecated but texid mode needs to stay around
until all clients can be upgraded.
In an early prototype, this functionality was added directly into
Texture but required quite a bit of additional state tracking, so the
Stream API seemed like a better fit.
This API is probably not necessary for Metal due to Metal's shared
ownership semantics.
This has been tested with a new Android sample that will be added in a
subsequent PR.
This is useful for unit tests. The content of the swapchain can be
read to main memory with Renderer::readPixels().
This PR doesn't implement this new feature in the following backends and
platforms (TODO):
VulkanDriver.cpp
MetalDriver.mm
PlatformWGL.cpp
PlatformWebGL.cpp
PlatformCocoaTouchGL.mm
Filament keeps a global static list of engines for verification purposes
which was being recreated multiple times, causing a panic. After a lot
of experimentation with the build, I was not able to fix this while
keeping the current scheme of dynamically loading both libraries.
As a "solution", we now staticly link filament into gltfio-jni, and ask
clients to load only that.
Fixes#1811.
This simple Kotlin app projects a live feed on the side of a cube.
It looks very similar to the `lit-cube` demo but there is a new Kotlin
class called `CameraHelper` that creates Camera2 objects, starts
the capture session, creates the Filament texture, etc.
For now, this app uses SurfaceTexture. This is a starting point and
provides a testing ground for tentative improvements to our Stream API.
