javafx-3d

Is it possible in a JavaFX 8 3D scene to find points along a ray (e.g. PickRay), starting at an arbitrary point in 3D space with some 3D direction vector, where the ray intersects the triangles in a mesh (TriangleMesh inside a MeshView)? I know this is done in the Camera/MouseHandler for mouse picking but I can't see any way for doing it for arbitrary rays. As @jdub1581 suggests, a ray is just a geometric vector, so in order to find a list of triangles intersected by this vector we need to solve problems of the kind 'line intersects plane' and 'line intersects plane within the triangle borders

My goal is a game played with dice. I am using javafx. First question: Is there an easy way to customize the 3d box in javafx. It doesn't matter to me, if I have to add an image to every side of the die or if I use just one image which wraps around the box. (After lots of research I didn't find anything about it.) In the code below I created a stackpane, which is a 3d cube. It is build from 6 Rectangles, each of the is filled with one side of a die (1 to 6). If I rotate the stackpane by 180 degrees, the Rectangle which should be in the foreground is in the background and the one which was

I have a sample 3D application (built by taking reference from the Javafx sample 3DViewer) which has a table created by laying out Boxes and Panes: The table is centered wrt (0,0,0) coordinates and camera is at -z position initially. It has the zoom-in/out based on the camera z position from the object. On zooming in/out the object's boundsInParent increases/decreases i.e. area of the face increases/decreases. So the idea is to put more text when we have more area (always confining within the face) and lesser text or no text when the face area is too less. I am able to to do that using this

I have a 3D scene in JavaFX and need to overlay GUI over the 3D scene. I have tried adding buttons and text to the scene but they always appear in the 3d view as 3D objects. I have looked around and haven't found how to do it. The only workaround would be creating a whole new window and putting the settings there but that isn't an option in this case. Thanks for the help!! Something like this Or this José Pereda The best solution for what you are looking for is the SubScene , a built-in JavaFX container : The SubScene class is the container for content in a scene graph. SubScene provides

I'm using JavaFX to move 3D cubes around by mouse drag. The cube should stay on the plane spanned by x and z axis. My solution works fairly well, however if I move the cube too fast with my mouse or when it encounters an object with a certain depth (y-Axis), it is assumed, that the mouse is moving on the y-Axis and the cube starts jumping forward or backwards. Is there a way to restrict the mouse to the xz-plane? A more complicated solution would be projecting the y length back to the xz-plane, but I got no clue how. I looked at JavaFX Moving 3D Objects , but couldn't adapt it to my case. My

How do you create a video wall like in the JavaFX 2.0 demo here: https://www.youtube.com/watch?v=UXSmJYFrulY#t=411 For a start it doesn't have to be videos, it can be images as well. All I'd like to have is to place the nodes like they are in the video, i. e. in a curved shape like the insides of a cylinder or a sphere. Or is the source of that demo available somewhere? Thank you very much. I researched and found a very awesome site with the relevant information: http://paulbourke.net/geometry/transformationprojection/ The relevant part was the Coordinate System Transformation, in particular

How can I fill in JavaFX a 3D Sphere with a linear gradient like a 2d Circle? I work with the JavaFX Scene Builder. As @mohsenmadi has pointed out, the diffuse color doesn't allow you using other than one single color. But you can have different colors on the sphere by using an image as a diffuse map. Based on your first image, I've created this texture image (called diffuse.jpg , and placed under the same folder as the JavaFX class): You can create now your bicolored sphere: @Override public void start(Stage primaryStage) throws Exception { // 3D Sphere sphere = new Sphere(5); PhongMaterial
