+
+# Change Log
+
+#### v0.3.0
+
+This release involved considerable internal refactoring, allowing us to expose more Filament functionality on the Dart side. Previously, most of this functionality was 
+rigidly implemented in C++ and didn't allow for end-users to take advantage of Filament directly.
+
+This also means there are a number of breaking changes from `0.2.1`. To summarize:
+
+- `ViewerWidget` has been introduced. This is a Flutter widget for users who only need basic rendering and don't need/want to deal with camera/materials/etc directly.
+- Users who want more fine-grained control than a `ViewerWidget` can still work with `ThermionViewer` and `ThermionWidget`.
+- The singleton `FilamentApp.instance` exposes methods for working almost directly with the underlying Filament engine (e.g. loading custom materials from `Uint8List`, creating textures, etc).
+- New interfaces have been added for `Material`, `MaterialInstance`, `Texture`, `View`, `Scene` and `Camera`.
+- `ThermionAsset` replaces `ThermionEntity` as the main interface for scene objects.
+- Transforms/material instances should be set directly by `asset.setTransform`, `asset.setMaterialInstanceAt`
+- Material properties can be set directly on the `MaterialInstance`, e.g. `materialInstance.setParameterFloat4("baseColorFactor", 1.0, 0.0, 0.0, 1.0);
+- Linux binaries have been added to `thermion_dart`. This package can be run on Linux (which we are using for CI and automated testing) but there are not yet any Flutter bindings, so `thermion_flutter` cannot run on Linux yet.
+- On Windows, `thermion_flutter` now uses the Vulkan backend. This is still experimental and will have limited supported on older hardware (pre-2018).
+-  Web support for `thermion_dart` has now reached parity with other platforms, though should still be considered experimental. Some manual steps are required to run in a Flutter app or a Dart web app.

-## Camera Manipulation (Flutter)
-
-> You can find the entire project below in the [flutter/quickstart](https://github.com/nmfisher/thermion/examples/flutter/camera_manipulation) folder.
-
-A `ThermionListenerWidget` is one option for manipulating the camera with an input device (e.g. mouse or touchscreen gestures). 
-
-This will generally wrap a `ThermionWidget`, meaning the entire viewport will act as a receiver for gesture events. 
-
-> You can position this independently (for example, stacked vertically beneath the viewport), but this will not translate picking queries correctly.
-
-```
-@override
-  Widget build(BuildContext context) {
-    return Stack(children: [
-      if (_thermionViewer != null)
-        Positioned.fill(
-            child: ThermionListenerWidget(
-                inputHandler:
-                    DelegateInputHandler.fixedOrbit(_thermionViewer!)
-                    ..setActionForType(InputType.MMB_HOLD_AND_MOVE, InputAction.ROTATE)
-                    ..setActionForType(InputType.SCALE1, InputAction.ROTATE)
-                    ..setActionForType(InputType.SCALE2, InputAction.ZOOM)
-                    ..setActionForType(InputType.SCROLLWHEEL, InputAction.ZOOM),
-                child: ThermionWidget(
-                  viewer: _thermionViewer!,
-                ))),
-    ]);
-```
-
-`ThermionListenerWidget` is a very simple widget; it simply forwards pointer, gesture and keyboard events to the provided [InputHandler], which must decide how to interpret those events.
-
-For example, one [InputHandler] implementation might interpret mouse pointer movement as "rotate the camera", whereas a separate implementation might interpret it as "translate this specific entity".
-
-Thermion provides two default InputHandler implementations for manipulating the camera: [DelegateInputHandler.fixedOrbit] and [DelegateInputHandler.flight].
-
-[DelegateInputHandler.fixedOrbit] will rotate the camera in a fixed orbit around a target point (the origin, by default), and also allow zooming in/out (subject to a minimum distance, which is configurable).
-
-By default, [DelegateInputHandler.fixedOrbit] will:
- rotate the camera when the middle mouse button is held and the pointer is moved (on desktop), and when a single swipe left/right/up/down is detected (on mobile)
- zoom the camera when the scroll wheel is scrolled up/down (on desktop), and when a pinch gesture is detected (on mobile)
-
-You can change the action for a specific input type by calling `setActionForType`; for example, if you wanted to rotate the camera by moving the mouse pointer while holding the left mouse button, you would call:
-
-```
-setActionForType(InputType.LMB_HOLD_AND_MOVE, InputAction.ROTATE)
-```
-
-See the [InputType] and [InputAction] enums for available input types and actions.
-
-[DelegateInputHandler.flight] will translate keyboard and mouse/touchscreen gestures to free flight camera manipulation. 
-
-By default:
- holding the middle mouse button will control the pitch/roll/yaw of the camera
- holding the left mouse button will pan the camera left/right/up/down
- the middle mouse button will zoom/dolly the camera in/out
- the WASD keys will pan the camera left/right/up/down and dolly the camera forward/backward
-
-If these don't exactly fit your use case, you can create your own [InputHandler] implementation. If you think it would be useful to other users, please feel free to submit a PR for your implementation to be included in the base Thermion package.

+## Getting Started
+
+Thermion currently requires the Flutter `master` channel with the `native-assets` experiment enabled.
+
+1. Switch to Flutter master channel, upgrade Flutter, create a new project, then add `thermion_flutter` as a dependency
+
+```bash
+$ flutter channel master
+$ flutter upgrade
+$ flutter config --enable-native-assets  
+$ cd your_flutter_project
+$ flutter pub add thermion_flutter
+```
+
+2. If running on iOS or MacOS, change the minimum deployment target to OSX 13
+
+<Accordion title="Click to open iOS/MacOS instructions">
+
+Make sure the `platform` entry refers to `13.0` in your Podfile.
+
+In `macos/Podfile` (for macOS):
+```
+platform :osx, '13.0'
+```
+
+In `ios/Podfile`, (for iOS):
+```
+platform :ios, '13.0'
+```
+
+Then open XCode:
+```

-## Quickstart (Flutter)
+## ThermionViewer (Flutter)

-> You can find the entire project below in the [examples/flutter/quickstart](https://github.com/nmfisher/thermion/tree/master/examples/flutter/quickstart) folder of the repository.
+If you just want to display a 3D object in the viewport with some basic camera controls, use the [ViewerWidget described in the Quickstart section](./quickstart).

-1. Switch to Flutter master channel, upgrade Flutter, create a new project, then add `thermion_flutter` as a dependency
+If you need want more fine-grained control 

-```bash
-$ flutter channel master
-$ flutter upgrade
-$ flutter config --enable-native-assets  
-$ flutter create thermion_sample_project && cd thermion_sample_project
-$ flutter pub add thermion_flutter
-```
+> You can find the entire project below in the [examples/flutter/viewer](https://github.com/nmfisher/thermion/tree/master/examples/flutter/viewer) folder of the repository.

-2. If running on iOS or MacOS, change the minimum deployment target to OSX 13

-<Accordion title="Click to open iOS/MacOS instructions">

-Make sure the `platform` entry refers to `13.0` in your Podfile.

-In `macos/Podfile` (for macOS):
-```
-platform :osx, '13.0'
-```
-
-In `ios/Podfile`, (for iOS):

 ### Flutter

-Thermion requires Android SDK version 22, so change your `app/android/build.gradle` to match this version or higher：
+Copy thermion_dart.js and thermion_dart.wasm to the `/web` folder for your target app.

-```groovy
- defaultConfig {
-    ...
-        minSdk = 22
-    ...
-    }
-```

-### Quickstart (Flutter)
-
-```
-_thermionViewer = await ThermionFlutterPlugin.createViewer();
-
-// Geometry and models are represented as "entities". Here, we load a glTF
-// file containing a plain cube.
-// By default, all paths are treated as asset paths. To load from a file 
-// instead, use file:// URIs.
-var entity =
-    await _thermionViewer!.loadGlb("assets/cube.glb", keepData: true);
-
-// Thermion uses a right-handed coordinate system where +Y is up and -Z is
-// "into" the screen.
-// By default, the camera is located at (0,0,0) looking at (0,0,-1); this
-// would place it directly inside the cube we just loaded.
-//
-// Let's move the camera to (0,0,10) to ensure the cube is visible in the
-// viewport.
-await _thermionViewer!.setCameraPosition(0, 0, 10);
-
-// Without a light source, your scene will be totally black. Let's load a skybox
-// (a cubemap image that is rendered behind everything else in the scene)
-// and an image-based indirect light that has been precomputed from the same
-// skybox.
-await _thermionViewer!.loadSkybox("assets/default_env_skybox.ktx");
-await _thermionViewer!.loadIbl("assets/default_env_ibl.ktx");
-
-// Finally, you need to explicitly enable rendering. Setting rendering to
-// false is designed to allow you to pause rendering to conserve battery life
-await _thermionViewer!.setRendering(true);
-```
-
-and then in your Flutter application:
-```
- @override
-  Widget build(BuildContext context) {
-    return Stack(children: [
-      if (_thermionViewer != null)
-        Positioned.fill(
-            child: ThermionWidget(
-          viewer: _thermionViewer!,
-        )),
-    ]);
-  }
