[JAVA3D] Drawing Text on a Canvas3D

Hello folks, I need to draw text on a Canvas3D using a Truetype font. The text must not be on an opaque background (otherwise I could simply use a java.awt.Canvas or a java.awt.Textfield). Also, for performance reasons, I do not want to use an OffScreenBuffer. For the same reason I want to kee

Hello Janet, The reason why you get an infinite loop is because the loader can not find the object files (*.lwo) in your *.lws file. Open the lws file with a text editor and make sure the paths to your object files are correct. If you have the lwo files in the same directory as your lws files yo

Rayan, in an object without holes every vertex is typically shared by three or four polygons. If they all reference the same vertex, that vertex only has to be transformed and lighted once instead of three or four times as is the case with the same object represented by a non-indexed GeometryArra

Hi Eric, first, as I've done behaviors and picking without using the SUN utilities package, this is only a hint: picking will supply the shape3D nearest to your viewplatform. Get its bounds and calculate a wire frame box. You can use IndexedLineArray or IndexedQuadArray (here u'll need PolygonAtt

Re: [JAVA3D] Plant Visualization

I think the answer depends on what kind of visualization you want. If you just need the physical structures and layout, I think VRML is probably a better answer. Many CAD programs output directly to VRML 2.0. If your's doesn't, take a look at "Crossroads" it's a geometry translator that works wel

Re: [JAVA3D] dual processor performance

Java 3D will take advantage of any CPU resources available. How much they are used depends upon the application. Visualization of a static scene will most likely only use one CPU, because all it is doing is rendering. The more dynamic the scene, the more a second CPU will be used. More feature
