Re: [JAVA3D] What do you want/need from Java3D?
I'm using Java3D for a spare time project: http://jose-chess.sourceforge.net. Having no background in 3D programming, I found Java3D an excellent framework for learning without having to delve into OpenGL, etc. I can't speak for professional graphics programmers, but J3D is the choice for hobby programming. And you get the additional bonus of platform independence. I have no specific demands for future development, but seeing J3D wither away would be really a pity. It doesn't really matter if the sources remain closed or open, but I would strongly recommend (given the complexity of the project) a profesional guidance (maybe you, Justin ?). Also Blackdown seems to have some competence in Java3D. Dropping DirectX in favor of OpenGL might be worthwile. It would open the way for a layered architecture (which other posters have already suggested). -- Peter === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

Re: [JAVA3D] mirroring problem
I'm using simply
setCullFace(PolygonAttributes.CULL_FRONT);
there's no need to manipulate the geometry.
If you're using directional lights, you have to mirror the light sources,
too.
And then you have to make sure that the original lights will only affect the
original objects,
and the mirrored lights will only affect the mirrored objects:
DirectionalLight.setInfluencingBounds(...)
(if you forget this, the mirrored objects will be lighted by both light
sources).
Hope this helps,
Peter

Re: [JAVA3D] Texture Loading/Choppy Frame Rates
are you using a Clip object ?
some graphic cards support only 2 clipping planes for textured objects
(4 for untextured objects).
If you have more than 2 planes the driver might
use some kind of software emulation for the remaining planes.
(that was my experience, though it had little impact on performance)

[JAVA3D] ModelClip bug ?
Hi there ! I think I've found a bug in the ModelClip class. If the model clip contains at least 3 clipping planes AND if it is applied to a textured object, only two clipping planes are actually effective. If the object has no texture, all clipping planes are effective. is this a known bug ? if so, is there a work-around ? Thanks in advance, Peter (attached images: txt-0002.jpg: a colorcube without texture; 3 corners cut off txt-0003.jpg: the same cube with a texture: only 2 corners cut off ???) <><>

[JAVA3D] What exactly are Device Coordinates ?
Hi there ! the javadoc for PolygonAttributes says public void setPolygonOffset(float polygonOffset) Sets the constant polygon offset to the specified value. This screen space offset is added to the final, device coordinate Z value of polygon primitives. I figured out that small values (< 1) will effect not very much. But large values (> 30) will mess up the front-to-back ordering of objects. Could anyone explain to me what's the relation between "screen space" and "device coordinates" ?

[JAVA3D] Reflection Mapping: it's beautiful, but...
Hi folks, I just started playing around with reflection mapping, using a TextureCubeMap. The first results are breathtaking, really a nice technique ;-) however, I have a question: when the map is projected onto a sphere (like in the attached image), the bottom face of the cube is spread around the rim of the sphere (the bottom face is the turquoise colored rim). It appears to me like the cube is mapped only to the visible hemisphere. I think this is hardly realistic !? Could someone explain why this must be so ?

[JAVA3D] can't detect multiple collisions
Hi there,
I have a problem with collision detection. If an objects collides with a
series of other objects,
only the first collision gets reported.
For example:
object X hits A --> WakeupOnCollisionEntry A
hits B while still intersecting A --> nothing happens
leaves A while still intersecting B --> nothing happens
leaves B --> WakeupOnCollisionExit A
what I was expecting is:
Enter A
Enter B
Exit A
Exit B
is this a problem with Java3D (1.3 beta1), or have I made a mistake ?
The behavior was set up with
Shape3D x = pickedGroup.getShape();
WakeupCriterion[] criteria = {
WakeupOnElapsedFrames(0,false),
WakeupOnAWTEvent(MouseEvent.MOUSE_RELEASED),
WakeupOnCollisionEntry(x, WakeupOnCollisionEntry.USE_BOUNDS),
WakeupOnCollisionExit(x, WakeupOnCollisionExit.USE_BOUNDS),
};
WakeupCondition wakeUpOnDrag = new WakeupOr(criteria);
...
wakeupOn(wakeUpOnDrag);
setCollidable(true) has been set for all relevant objects
I also tried WakeupOnCollisionMovement() but again, only events for the
first collision are reported
any help is appreciated ...

[JAVA3D] controlling the frame rate
Hi,
I have an application where the user is dragging objects around the scene.
When there is no user interaction I lower the frame rate to about 1 frame

frame is still
rendered after one second, so there is a noticeable delay.
Is there a way to force rendering of the next frame immediately ?

Re: [JAVA3D] How much Hardware Memory does Java3D need ?
Hello, yes, I'm using a high resolution (1600x1200). But many applications support it, only Java3D doesn't. So I wondered how many graphics card memory is used by Java3D. (roughly calculating, 1600x1200x16bit = 4MB; the graphics card has 32MB; even with double buffering there should be plenty of space ?!?) Is there a way to change the screen resolution from Java3D, or at least to determine the current resolution ? Is there a way to disable double buffering ?

Hi Peter I had the same problem. It is not realy a Java3D problem. I have a NVIDIA TnT2 card with 16 MB ram and a desktop resolution of 1280x1024. Now if I switch to fullscreen mode I will get the not enough hardware memory error. But if I change my desktop resolution to 1024x768 it works fine.
