* move the focus distance from DofOptions to Camera
The DofOption parameter is now deprecated, but will still work if the
focus distance is not set on Camera.
* A few new helper APIs on Camera
- getFocalLength() which returns the focal length used internally for
DoF computations.
- computeEffectiveFov() and computeEffectiveFocalLength() which can be
used to better simulate a real camera's FOV changes with the
focus distance.
Modified gltf_viewer so it uses the effective fov/focallendth when
DoF is active.
* simplify setLensProjection
We can call setProjection directly instead of converting to a fov
first, which ends up performing atan(tan(x)).
Also improve parameters names.
- setImage() used the width of the texture for calculating the required
user buffer size, but this was too large when only updating a
portion of the texture. It would result in a BufferOverFlowException.
- setImage3D() had the opposite problem where it didn't take into
account the depth of the texture.
- the offset in the user buffer was called "bottom" on the C++ JNI side,
but it is called "top" on the java and filament side.
Fixes#3685
Currently the only NONE and MEDIAN are available options, at some
point we may add a "MAX" option which is cheaper.
There is no real practical uses for this option with these only two
choices, other than for debugging.
* gltfio: Add internal MorphHelper, enable up to 255 targets.
Previously, gltfio could not animate models with more than 4 morph
targets. Now we can handle up to 255 targets, as long as no more than
4 targets are ever used simultaneously. This allows us to handle
many more models, such as those exported by Modo, and the horse model
in #1852.
We do this by picking the highest 4 weights. The indices for these
weights are called the "primary indices", and we construct a new
VertexBuffer for each unique set of primary indices.
In the near future this will be made more efficient by adding a new
VertexBuffer API to the Filament core.
Fixes#1487.
* Code review fixups.
This fixes two different logcat messages that would occur when scrubbing
a slider in the UI:
- "Discarding message, message queue overflow."
- "Downloading model..." would repeat itself needlessly
- Add a "shift" parameter to Camera. This has the effect of translating
the viewport, without changing its size.
This is an effect similar to using a shift lens.
- Camera::setScaling() now takes a double2 instead of double4, this is
because scaling the result of the projection in the Z direction
can lead to very confusing problems -- it will essentially move the
near/far planes, and we don't want to expose that as a public API.
- setCustomProjection() now allows to set a different projection for
rendering and culling (useful for e.g. for using an infinite far
rendering projection matrix).
This adds a WebSockets server to filament-utils-android.
Unlike my first attempt (#3599), this does not use a piping server and
is therefore much faster to use over a LAN. It also has lower user
friction because there is no need to touch a button in the app or
scan a QR code.
This adds libs/viewer to filament-utils-android and provides JNI
bindings for AutomationEngine.
This commit also changes the AutomationEngine to use PPM for screenshots
rather than PNG. The reasoning is that it is wasteful to include stb and
our two image-related libraries just to dump screenshots, especially for
a feature we might not use on Android.
Mathias noticed that the `setAcquiredImage` method was not well
documented on the C++ side. While fixing this I figured I'd try to write
up a docstring for the class itself.
* Stop using members as globals between methods
* Multi-thread shaders generation with JobSystem
* Pass JobSystem to MaterialBuilder::build()
* Fix MeshAssimp to use the new API
* Allow the Java API to pass a job system via Engine
* Update docs
* Apply suggestions from code review
