flutter_fbx3d_viewer 0.0.3

Flutter package for viewing Fbx 3d animated files. Now it is only a non textured version.

Flutter FBX 3D Viewer

Flutter package for viewing FBX 3D animated files

Support me: https://www.paypal.me/LaszloKozari

This library is experimental. Some FBX files, particularly older fbx files, may not load correctly. No guarantee is provided as FBX is a closed proprietary format.

This library is based on the dart_fbx library

Example

Fbx3DViewer(
  size: Size(ScreenUtils.width, ScreenUtils.height),
  zoom: 30,
  path: "assets/knight_2014.fbx",
  fromAsset: true,
  showInfo: true,
  rotateX: false,
  rotateY: false,
  showWireframe: true,
  wireframeColor: Colors.blue,
  initialAngles: Math.Vector3(270, 10, 0),
);

FBX Viewer

Properties

path: you can add an asset path (fromAsset=true) or you can add an SD card path (fromAsset=false)

zoom: Initial zoom.

showInfo: Show infos like FPS, and vertices.

rotateX: Animating the object with a rotateX.

rotateY: Animating the object with a rotateY.

showWireframe: Show the wireframe.

wireframeColor: Color of the wireframe.

initialAngles: Initial model angles.

Convert an FBX binary file to an FBX ASCII file that can this library handle

1, First step is to download an animated/rigged fbx binary file from the net:

https://www.turbosquid.com/3d-models/free-female-character-rigged-biped-3d-model/569036

Lets see this model. (you will download Mixamo-Joan_InjuredWalkAnimation.fbx Autodesk FBX - 4.22 MB)

2, Second is to load that modell with AUTODESK MotionBuilder 2020

You just drop you file to your MotionBuilder then FBX Open -> mixamo.com

3, Python Tools -> FBX Export on the MotionBuilder

FBX Version: FBX 2014/2015 -> Export

SAVE -> .fbx (ASCII)

Embed medias checked only

Save options:

Remove: (Settings)

Base Cameras

Camera switchers

Current camera

Global Lighting

Transport

Remove: (Scene)

Cameras (all)

Textures (all)

Video

4, SAVE

Now if everything is went good in the fbx file header you can see this: ; FBX 7.4.0 project file

Limits

FBX is a closed format, so while this library does it's best to interpret the data in an FBX file, I cannot guarantee that it will read all FBX files, or all data within FBX files.

No texture

Please don't use this library with a lot of vertices/polygons. Speed will be very low on huge point count.

Normal speed will be on an fbx that is max 3000 vertices. (Becuse it is draw with the CPU not on the GPU)
