Help: Reinstall caused J3D to not use Hardware acceleration

843799Jan 2 2002 — edited Jan 3 2002
System Specs: AMD Athlon 1400MHz, GeForce 2 MX 400 & ATI Rage32 (dual monitor), Windows 98, 256MB DRAM

I've been trying to figure out whether to use C++ or Java3D for an upcoming project. So I downloaded and installed J3D. I got 300+ frames/sec on the J3DFly demo application. Video performance was the only thing holding me back from using Java, so after seeing the J3DFly results, I decided to use Java.
In preparation to the project, I tore out my previous Java installations (Sun and IBM) and did a fresh re-install of Java 1.3.1_02 SDK and Java3D 1.2.1 OpenGL SDK. Swell. Re-ran the J3DFly program and got >>5<< FPS. ?!?!?
I've done everything that I can think of: switched to DirectX, tried to force hardware rendering, tried fresh re-installs. No luck.

- Anyone have any idea what happened or how to fix it?
- What framerates are people seeing on the J3DFly with the City scene?
- Is there any way that Java3D is not installing the proper hardware-accelerated DLL?
- Could my second non-3D accelerated graphics card be screwing Java3D up?

Thanks,
Alson

Bump! Just started working with trees and I've realised the same.

APEX Dev team - what version of jsTree is shipping with APEX 5? Are there improvements planned?

Answer

the node expanding missing is caused by some CSS and can be fixed with this:

body .tree > .ltr > li {

  display: block;

}

In apex 5, at least EA2, the tree component is still vastly outdated at version 0.9.9a2. I've a plugin which brings jstree 1.0.0 to apex at my github. It is very much functional but might still need some minor features. My demo page is still rudimental but it all works. jstree version 3 has been released in the mean time, and once I'm satisfied with what I have now I'd like to upgrade to v3. https://github.com/tompetrus/oracle-apex-ajax-tree I however consider the strength of the tree to be the javascript side, and many implementations in the tree are to be done with javascript. I'm not considering coding in much more than what I have at the moment.

Perfect - this makes a big difference thank you Tom.

I'm still baffled that jstree has not been updated. A more interactive hierarchy functionality would increase APEX's value as a corporate tool for navigating people hierarchies, if nothing else. This opens up a wealth of possibilities in terms of applications.
