Looks good. Approved.

One more (minor) update to fix a problem with the name of the test class (else gradle will not execute it). I also updated the copyright date in NGShape. The fix itself is unchanged from the initial webrev. http://cr.openjdk.java.net/~kcr/RT-35019.02/

Updated webrev with a regression test (the fix itself is unchanged). http://cr.openjdk.java.net/~kcr/RT-35019.01/ The regression test fails without the fix and passes with the fix.

Please review the following: http://cr.openjdk.java.net/~kcr/RT-35019/ Reviewers: flar Simple fix to avoid creating a texture with 0 width or height (which will fail) and return without rendering anything, since there is nothing to render in that case anyway.

This is caused by trying to draw a primitive whose bounds is 0 in either X or Y with a 3D transform. The following simple test case will reproduce the bug. import javafx.application.Application; import javafx.scene.Group; import javafx.scene.PerspectiveCamera; import javafx.scene.Scene; import javafx.scene.shape.Circle; import javafx.scene.text.Text; import javafx.scene.transform.Rotate; import javafx.stage.Stage; /** * Test program for rendering shapes with empty bounds and a 3D transform */ public class Test3DEmptyBounds extends Application { @Override public void start(Stage stage) { Circle emptyCircle = new Circle(10, 10, 0); Text emptyText = new Text(10, 100, ""); Group root = new Group(emptyCircle, emptyText); root.setRotationAxis(Rotate.Y_AXIS); root.setRotate(-30); Scene scene = new Scene(root, 400, 300); scene.setCamera(new PerspectiveCamera()); stage.setScene(scene); stage.show(); } public static void main(String[] args) { Application.launch(args); } }

This is a regression introduced in FX 8 by the fix for RT-5534. The attached program runs fine in FX 2.
25-03-2014
JavaFXApplication1.zip sample application attached. run the application, click on green button, try to resize application window or try to rotate scene using mouse drag inside of scene. jdk used: jdk8 b123 x64 environment: win7 hint: cannot reproduce the bug without of line 85 in ColorApp1.java: nonresizeable.setTranslateZ(i);

Victor, please attach a standalone test program that reproduces this, and then reopen it. Note that I have made this bug public since there is no reason for it to be internal.

update: 100% reproducible with b120 8u-cpu build. Test scene consists of few VBoxes(HBoxes, FlowPanes) with circles and a button inside.

Do you have a test case?
