Since JDK8u60 b14 transparency is enabled in 3D shapes. This is a quick test done with it: A cylinder with diffuse color Color.web(“#ffff0080”), is added on top of a box and two spheres. group.getChildren().addAll(sphere1, sphere2, box, cylinder); There’s no depth sort algorithm though, meaning that order of how 3D shapes are added to the scene … Read more

For one mesh there’s one material, and it’s not possible to assing different materials to different triangles of the same mesh. So if you want to avoid textures, I’m afraid the only way is grouping triangles with the same color … Read more

The idea is based on how the camera projection works, and it is based on the com.sun.javafx.scene.input.InputEventUtils.recomputeCoordinates() method that is … Read more
