9 years ago Why don't you import the CAD model directly with JCSG via STL.file()? The Caused by: java.lang.StackOverflowError error is not necessarily an error of the JCSG library. Please make sure that the stack of your JVM is big enough (e.g. -Xss515m). If this does not solve your problem you should post the model that you are trying to import.
When I load a .stl and convert to CSG (of the JCSG library) through this method, any boolean operation I perform fails. However simple models native to the JCSG library works fine.
So I get my CSG in a HashMap with the Node (JavaFX node of the CAD model) as a key and then perform the boolean operation union for example like this:
HashMap<Node, CSG> objCSGMap = contentModel.getObjectCSGMap(); Node obj1 = contentModel.getObjGroup().getChildren().get(0); Node obj2 = contentModel.getObjGroup().getChildren().get(1); CSG csg1 = objCSGMap.get(obj1); CSG csg2 = objCSGMap.get(obj2); CSG result = csg1.union(csg2); contentModel.set3dContent(result.toJavaFXMeshSimple().getAsMeshViews().get(0), null);
This is the error message:

However, this works fine:
CSG csg1 = new Cube(10, 70, 4).toCSG(); CSG csg2 = new Cube(40).toCSG(); CSG result = csg1.union(csg2); contentModel.set3dContent(result.toJavaFXMeshSimple().getAsMeshViews().get(0), null);
So it looks like boolean operations work fine for simple CSG objects from the JCSG library itself and not imported CAD files that have been converted to CSG objects through this method.
