Re: [JAVA3D] Java3D Win D3D & OpenGL in a single package!!!

[Mike Goldwater]

Hi,   I have managed to do some tests to establish the limits of my machine and Java when using large memory. My machine is an Acer Ferrari (not my choice of name) with an AMD64 processor, 2GB memory (currently 4GB with virtual memory) and the video is ATI mobility Radeon 9700 with 128MB memory. My tests are summarized below. My application runs using 2D graphics but can display a 3D window.   Java Version J3D Driver J3D Version Max memory (using –Xm option Result 1.3.1_03 D3D 1.3.1 >512MB Not examined 1.3.1_03 OpenGL 1.3.1 >512MB Blue screens with J3D on much higher memory 1.4.2._05 D3D 1.3.2 exp <=1022MB J3D works 1.4.2._05 D3D 1.3.2 exp <=1256MB 2D works; J3D fails (gets stuck) 1.4.2._05 OpenGL 1.3.2 exp <=846MB J3D works 1.4.2._05 OpenGL 1.3.2 exp <1256MB 2D works; J3D causes error in atiogl.dll; program vanishes, but computer still OK. 1.4.2._05 Either 1.3.2 exp >1256MB Heap error – program never started. In all cases the D3D performance was very poor when polygon edges were displayed. Heap error = Error occurred during initialization of VM Could not reserve enough space for object heap   Why does Java completely fail to start when you have memory >1256MB? Because blue screen failure recovery is very time consuming I did not examine in detail the behaviour of the earlier versions. Obviously I must contact Acer about the OpenGL driver errors.   Regards Mike Mike Goldwater Auric Hydrates Ltd From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of Alessandro Borges Sent: 13 October 2004 13:31 To: [EMAIL PROTECTED] Subject: Re: [JAVA3D] Java3D Win D3D & OpenGL in a single package!!!   Yes, they do. And if you have a testcase it could be nice. I guess can be very interesting studying your case in another video card model.   About lines, as the old Java3D D3D readme says, line thickness is not available in D3D mode.    Alessandro  Mike Goldwater <[EMAIL PROTECTED]> wrote: Hi,   D3D performance improves when the model is very small (not surprising - but needed to be demonstrated).   Do official J3D developers read these pages or do I have to post this elsewhere?

From the hints I thought it might be worth trying the D3D version. I have just tried your link to a recent build of J3D with D3D on my biggish engineering application.  It draws loads of quadrilaterals. When it just draws colours it is fine. However when I switch on the polygon outlines the D3D version slows right down to about down to about 1 frame/sec. On the OpenGL version it draws smoothly. Line thickness is ignored as in the bug pages.   Regards Mike Mike Goldwater   From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of Alessandro Borges Sent: 11 October 2004 19:37 To: [EMAIL PROTECTED] Subject: [JAVA3D] Java3D Win D3D & OpenGL in a single package!!!   Yes!!! One of the biggest  advantages of Java3D over the others 3D engines is the D3D support. As a lot of low end, as well  some high end ATI vcards, runs better using D3D, and this is a great thing for wider audiences. But we have to choose the desired package : D3D or OpenGL.  One or other. Now we have both ! Fresh new Java 3D  1.3.2 build 7 is 2 in one : D3D and OpenGL in a single package!! Better and smaller.  Just 1.35 MB. Congratulations, J3D team !!! use -Dj3d.rend=d3d to use DirectX as underlaying API. I havent tested it in deep, but up to now it works fine in our Win2K stations https://java3d.dev.java.net/  look  at downloads section ;) Alessandro   Yahoo! Acesso Grátis - Internet rápida e grátis.
