Just take the transform, which ever one you want, and run the points through the Transform3D.transform(...) method. The resulting point is the one you are looking for.
If you want to do this to an entire geometry, you will have to apply it to each coordinate separately (someone correct me if I am wrong). Java3D pushes this transform on the openGL pipeline then sends the coordinates. -mike -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of Serge Bernier Sent: Friday, September 03, 2004 11:50 AM To: [EMAIL PROTECTED] Subject: Re: [JAVA3D] transform question Hi, what I want to be able to have is not the t3d resulting from all the multiplication of the t3d from the parent nodes. It the result of the coord point of the geometry after applying the transformation. Let me explain by an example. I have a triangle array with only one triangle. The vertices are at: 1-0,0,0 2-1,0,0 3-0.5,1,0 Let cut down the problem an say I want to apply a translation to the triangle. T3D: A matrix translation of 1 in the X axis. After applying the t3d to the traingle the vertices have change location in the virtual scene. The final vertices of the triangle are: 1-1,0,0 2-2,0,0 3-1.5,1,0 I want to have this information. The result of the t3d multiplication on the geometry coord point. Not the final t3d apply to the geometry. Is it possible??
