[JAVA3D] texture transform interpolator

2000-01-16 Thread Jimmy Talbot
Hi, Are there any texture transform interpolators hiding anywhere? I'd like to have a texture scrolling on a panel. Of course I can't use a PositionInterpolator since it requires a TransformGroup, not a TextureAttribute. Thanks Jimmy ===

I have attempted to use Java3d to evaluate volumetric data which has some of the same problems you're running into. What I ended up doing was creating an IsoSurface from the volumetric data, by using the marching cubes algorithm The result is a triangle surface mesh. The density of the mesh is de

Jimmy, I demonstrate a (custom) Behavior for something similar to this in my forthcoming book: http://www.manning.com/Selman/index.html I wrote a Behavior that took a TextureAttributes object in its ctor and updated it inside processStimulus every N milliseconds. It worked pretty well for my exa

[JAVA3D] Picking non-live nodes

2000-01-16 Thread Andy Wilkinson
I'm rendering my scene entirely in immediate mode, hence the desire to pick objects which aren't live. I'm essentially keeping a full scenegraph and simply not attaching the root to keep it non-live so the nodes which are being transformed are added to TransformGroups. When a node is being render

[JAVA3D] VRML Loader

2000-01-16 Thread chong zhang
Hi, I am running one sample applet of vrml loader which loads wrl (VRML file) by using Java3D. It works ok when the wrl file is small such as 60kb. But when the wrl file is as big as 2mb (about 20,000 triangles), it display nothing, and sometimes make my computer (PIIC300 Win98) down. I guess i

[JAVA3D] Very slow on multiple panels

Hi all i have done many panels with Canvas 3D on it in a CardLayout, each panel showing different projections which i use a PopupMenu to control which panel should be shown. Now the problem is i try to only attach the view branchgroup to the locale when that panel for it is being shown... but

[JAVA3D] better picking

2000-01-16 Thread Jimmy Talbot
Hi, It sounds like there should be a much more efficient way of picking than shooting a ray in the scene -- at least for bounds picking. Since rendering maps the 3d world onto the screen, why not just remember which polygon generated each pixel (and somehow taking into account the objects that ar

[JAVA3D] java with vrml

Hi I wish that you send me samples of java3d with vrml. Is it possible (have virtual worlds construct in vrml using cosmosworld opened in java application)? Do I get to identify event on virtual worlds in vrml with code of java? Thanks Haroldo
