Flutter FBX 3D Viewer

Flutter package for viewing FBX 3D animated files with textures

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

FBX Viewer Example

Properties

  Fbx3DViewer({
    @required this.size,
    @required this.fbxPath,                 // "assets/asd.fbx" or sd card path
    @required this.lightPosition,
    @required this.initialZoom,
    @required this.animationSpeed,          // 0-1
    @required this.fbx3DViewerController,
    @required this.refreshMilliseconds,
    @required this.endFrame,                //max frame to play
    this.texturePath,                       // "assets/asd.png" or sd card path
    this.backgroundColor = const Color(0xff353535),
    this.showInfo = false,
    this.showWireframe = false,
    this.wireframeColor = Colors.black,
    this.initialAngles,
    this.panDistanceToActivate = 10,        //pan distance to activate swype
    this.onZoomChangeListener,
    this.onRotationChangeListener,
    this.onHorizontalDragUpdate,
    this.onVerticalDragUpdate,
    this.color = Colors.white,
    this.lightColor = Colors.white,
    this.showWireFrame = true,
    this.showGrids = true,
    this.gridsColor = const Color(0xff4b4b4b),
    this.gridsMaxTile = 10,
    this.gridsTileSize = 1.0,
  });

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.

2, Second is to load that modell with AUTODESK MotionBuilder 2020 or AUTODESK 3DS Max!

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

TRIANGULATE

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. You can play with FBX version 7.4 files ASCII text format

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 3000-5000 vertices
