Re: [JAVA3D] OpenGL or DirectX

I am not sure what you mean by different SDK having difference "javacs"... What I am saying is that each Javas3D run-time essentially consists of 1. A set of .class files stuffed into a few jar files 2. A set of DLLs (on win32). For the DirectX and OpenGL implementations both class files and DLL

I am in favor of including both versions at deployment. You can then let the user, by the use of a start-up configuration menu choose between the two and thereby let him/her use the one that works best on his/her machine. This can be implemented by including both versions with your app and then a

Re: [JAVA3D] OpenGL or DirectX

Kent, I use both on my system. I have the OpenGL SDK installed, but I also have the DirectX RT installed. This way, I can develop under one, then run under the other. By doing this, I can quickly determine if there's an issue with one of the two implementations. So far, I've only run into a

Microsoft has not yet written a 1.2 or 1.3 OpenGL library, but there is no need to worry or do anything. Various 3D card manufacturer implement their own version of the library. For instance, if you use a nVidia 3D card you already have OpenGL 1.3 installed. Application programs (e.g. java3D) can

That is correct. You have to be part of a live scene to call that method. That is because there is no "root" by which to calculate the ultimate destination of the points until it exists within the live scene. Dave Yazel - Original Message - From: thorsten topol <[EMAIL PROTECTED]> To: <
