Integrate 3D scene in a Java canvas (AWT, Swing, JavaFX or SWT) #5

Open jzy3d opened 3 years ago

jzy3d commented 3 years ago

Current prototype uses a native GLUT frame to render the scene, which is not suitable for a complete integration in a Java desktop application.

Ideas

Option 1 : Render offscreen, fetch image and add it to a classic AWT or Swing Canvas

Use FBO

Display in

AWT
JavaFX
Swing
SWT

Option 2 : Get a rendering context from a Canvas and expose GL functions with JExtract generated code

Pro : cleaner design similar to JOGL
Pro : Canvas may expose the current GL context hence avoid multithreading issues
Cons : requires understanding the depth of AWT & JDK

See JAWT See JAWT IN LWJGL See JAWT IN JOGL See Project Lanai for Metal support on MacOS.

Questions

Why Sun drop JOGL and Java3D in 2004? Are there fundamental reasons why making OpenGL from Java is not viable?
Would an AWT Canvas support rendering with both internal JDK native code AND OpenGL wrapped methods with JExtract?

Merged improvements based on FBO for Ubuntu branch, but still FBO on Linux is not resolved
