11 What is JavaFX 3D?!! JavaFX 3D is a general-purpose 3D graphics library for JavaFX 11

12 JavaFX 3D Overview JavaFX 3D leverages the 2D UI capabilities of JavaFX JavaFX 3D shares the same scene graph with JavaFX JavaFX 3D is not a thin wrapper around OpenGL/D3D JavaFX 3D is not a AAA game engine JavaFX 3D is easy to learn and use Check out MoleculeSampleApp.java 12

20 Modeling Modeling Building Transform Skinning or Parenting 3D Modeling Tools! Blender (Free!) Maya 3D Studio Max Lightwave Cheetah 3d Cinema 4d SketchUp Modo 20

21 Modeling Modeling Building Transform Skinning or Parenting 3D File Formats FBX: Popular Autodesk file format COLLADA (DAE): Open standard XML schema OBJ: Old format for polygon meshes, but still used STL: For Stereolithography and 3D printing 21

22 Modeling Modeling Building Transform Skinning or Parenting 3D Viewer Viewer for 3D geometry, skinning, animation Free, open-source, a lot of useful functionality Written to help us prepare JavaOne demos Experimental, rather than production code 22

23 Modeling Modeling Building Transform Skinning or Parenting 3D Viewer Importers Maya: Imports general polygons and triangles OBJ: Only imports triangles, not general polygons 3D Studio Max: Donated but untested DAE: Just a start 23

24 Modeling Modeling Building Transform Skinning or Parenting Other Importers (not part of 3D Viewer) FBX Importer by Tesis Dynaware source code at 3ds, COLLADA, OBJ, STL Importers by August Lammersdorf 24

25 Modeling Modeling Building Transform Skinning or Parenting Triangles vs. General Polygons Ultimately, all geometry gets turned into triangles However, keeping geometry as polygons for as long as possible has advantages for subdivision surfaces In animation, quads are preferred over triangles 25

27 Modeling Modeling Building Transform Skinning or Parenting Catmull-Clark Subdivision Surfaces is a generalization of a recursive bicubic B-spline patch subdivision algorithm. For rectangular control-point meshes, the method generates a standard B-spline surface. Edwin Catmull and Jim Clark,

29 Modeling Modeling Building Transform Skinning or Parenting Duke was designed by Joe Palrang!!! 29

30 Modeling Modeling Building Transform Skinning or Parenting Duke was originally modeled in 3D by James Gosling!!! 30

31 Modeling Modeling Building Transform Skinning or Parenting Duke was remodeled for animation for JavaFX 3D!!! 31

33 Modeling Modeling Building Transform Skinning or Parenting Model Resolution and Topology Matter for You don t want the resolution too high. Leave that for subdivision surfaces You don t want the resolution too low. If the resolution is too low, the mesh doesn t deform right when animated. 33

34 Rigging / Character Setup Modeling Building Transform Skinning or Parenting In order to animate a 3D model, you need a transform hierarchy to which the 3D geometry is attached. The general term for this part of the pipeline is rigging or character setup. Rigging is the process of setting up your static 3D model for CG animation, to make it animatable. 34
