[JAVA3D] Capturing Canvas3D

Hi, Does anyone know why canvas capturing doesn't work with ati radeon 9200 graphics card. Other cards I have tested, it works fine. I have used example code at j3d.org web page: http://www.j3d.org/faq/examples/CapturingCanvas3D.java -mikko

[JAVA3D] morphing, 3ds objects and the Starfire loader

Hi, I've been pleased to see the interest in skin & bones animation triggered by Mark's contribution recently. These are once again exciting times now that the Java3D code has become an open source Java.net project. OK, enough of that, on to my problem... I'm trying to morph between objects created

[JAVA3D] Mouse events

I have an application that is supposed to record the intersection point of a mouse click location and a Shape3D, *after* the user selects a particular menu option. I've set up a user-defined clickBehavior that gets triggered when the user selects the menu option and then performs a mouseclick. Mo

[JAVA3D] HyperThreading mess up Java 3D picking

Hi, All, Here is the problem: We have multiple machines in Windows XP that has intel P4 2.8G Hz+ CPU with Hyper Threading enabled. We found Java 3D picking action become very slow, even slower than machines with less than 1G Hz CPU. The pickCanvas.pickAllSorted() method is taking more than 10 tim

Re: [JAVA3D] HyperThreading mess up Java 3D picking

Hi, that sounds like a graphics driver problem. Have you tried it with the OpenGL- and the DirectX-version of Java3D? Michael On Wed, 30 Jun 2004 13:51:34 -0500, Hong Cao <[EMAIL PROTECTED]> wrote: Hi, All, Here is the problem: We have multiple machines in Windows XP that has intel P4 2.8G Hz+ CPU

Re: [JAVA3D] Mouse events

i think this is due to erroroneous mouse click. it happens in my program also. many times click is not considered by java. it is bcoz a small drag event get fired. i also solved the problem by considering the length of drag > I have an application that is supposed to record the intersection point

Re: [JAVA3D] Mouse events

Thanks -- I'll check whether a drag event is fired.

Re: [JAVA3D] HyperThreading mess up Java 3D picking : more detail.

I checked Java 3D source code, their handling of picking is not related to the graphic driver. Java code will calculate everything. So graphic card driver problem is ruled out. (Remember when disable HT, everything is fine.) As to OS, we did have similiar, actually more serious problem when we ins

Re: [JAVA3D] HyperThreading mess up Java 3D picking

I wanted to chime in on this. It is possible that hyper threading is making a difference because it does require support at the OS level. (If I am not mistaken). Given that, it is possible that something within the OS (including such things as graphics drivers) might not be handling hyper threadin

Re: [JAVA3D] HyperThreading mess up Java 3D picking : more detail.

I want to point out that picking is *heavily* related to graphics drivers/cards. Java code may be used to process results of picking, but picking itself is a hardware operation that occurs during rendering to framebuffers. This is at least the case in OpenGL, and im sure its the same in directX.

Re: [JAVA3D] morphing, 3ds objects and the Starfire loader

Hi Mark, sorry I shouldn't have put my comment about skin & bones animation in my message about morphing. It's just that I'm so excited about what is happening in Java3D these days and I welcome the interest being shown by people like yourselves for include skeleton rigging in the core system or, a

Re: [JAVA3D] morphing, 3ds objects and the Starfire loader

It's possible the order of the vertices is being messed up by our loader as I use: gi.recomputeIndices(); // "gi" is an instance of GeometryInfo and s3d.setGeometry(gi.getGeometryArray()); So if GeometryInfo alters the order of the vertices this could account for the problems seen. - John W
