Re: [JAVA3D] How execute an example in JBuilder 4 ?

You can do 2 things : - the first, say to the aplication which one of your classes have the main method. - the other is make click over the class with the right button of mice and select run. But you have to be sure that the aplication is ok... Robert 17/08/2001 4:11:00, Luis Fabio Magalhães <

Re: [JAVA3D] Installing Java3D in Win2000

I'm sorry to contradict you, but DirectX 8.0a is NOT necessary to install Java3D 1.2.1_01 on Windows 2000. Windows 2000 ships with DirectX 7 bundled in and Java3D works fine with it. - Original Message - From: "Enio Ribeiro Salles" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursd

[JAVA3D] Key events (a bit sluggish)?

This is not a really Java3D related question, but I need a very fast-moving demo where I can navigate a simple environment, using the keyboard. The problem is that events aren't handled very well in Java, are they? I mean, using Swing or AWT the menus behave a bit slowly, sometimes mouse eve

Re: [JAVA3D] Diferences between DirectX e OpenGL ?

Philip, What I meant to say is that my understanding is that DirectX has many features (perhaps 100 to 200 video functions - at one time I'd heard a figure of 63) and that each video card manufacturer may or may not provide support for each of those features (or may supply a slightly different im

Hi, I don't know which example you are trying to run, but you ask how to run an "applet" and JBuilder is asking for a "main" and "main" is only associated with applications. I sounds to me that you called up the source in the IDE window and hit the run button. JBuilder is attempting to run thi

Nikhilesh, Concerning your first point, most of the 3D model loaders (including the one we wrote for 3DS) use "TextureLoader" to read in the texture graphics. TextureLoader automatically adjusts for the 2 to the Nth power requirement. - John Wright Starfire Research Nikhilesh Haval wrote: > >
