Powei Feng afeae22423 android: [render-validation] collection of adjustments (#9898)
- A triangle tracker under the progress bar to track the test
   currently in view within the scroll view.
 - Text label to indicate the current device under test when a
   test is running.
 -  add filter intent arg
 - Add Fox (animation, skinning) and TransmissionRoughnessTest
   (transmission) to the test.
 - Add applyAnimation to the ValidationRunner
 - Make camera zoom in for default test and adjust tolerance
   acoordingly
 - Fix non-determinism of SSR by
     - waiting for more frames
     - account for false returned from beginFrame
     - Clear frame history on new test entry
 - Include Build.HARDWARE information into result
 - Make results array more thread-safe
 - Remove unused paths
 - Adjust tolerance for two tests

Filament sample Android apps

This directory contains several sample Android applications that demonstrate how to use the Filament APIs:

hello-triangle

Demonstrates how to setup a rendering surface for Filament:

Hello Triangle

lit-cube

Demonstrates how to create a light and a mesh with the attributes required for lighting:

Lit Cube

live-wallpaper

Demonstrates how to use Filament as renderer for an Android Live Wallpaper.

Live Wallpaper

image-based-lighting

Demonstrates how to create image-based lights and load complex meshes:

Image-based Lighting

textured-object

Demonstrates how to load and use textures for complex materials:

Textured Object

transparent-rendering

Demonstrates how to render into a transparent SurfaceView:

Transparent Rendering

texture-view

Demonstrates how to render into a TextureView instead of a SurfaceView:

Texture View

material-builder

Demonstrates how to programmatically generate Filament materials, as opposed to compiling them on the host machine:

Material Builder

gltf-viewer

Demonstrates how to load glTF models and use the camera manipulator:

glTF Viewer

hello-camera

Demonstrates how to use Stream with Android's Camera2 API:

Hello Camera

page-curl

Pure Java app that demonstrates custom vertex shader animation and two-sided texturing. Applies the deformation described in "Deforming Pages of Electronic Books" by Hong et al. Users can drag horizontally to turn the page.

Page Curl

stream-test

Tests the various ways to interact with Stream by drawing into an external texture using Canvas. See the following screenshot; if the two sets of stripes are perfectly aligned, then the Filament frame and the external texture are perfectly synchronized.

Building Samples

Before you start, make sure to read Filament's README. You need to be able to compile Filament's native library and Filament's AAR for this project. The easiest way to proceed is to install all the required dependencies and to run the following commands at the root of the source tree.

To build the samples, please follow the steps described in BUILDING.md
