In my case i have to load a file that consists of
the coordinates, Vertices and Facets of a polyhedron.
I have managed to isolate the useful information
from the text file, and now all i need is to supply these info in a program that
generate shape!
Here is my text file
Hi,
Measure your textures by pixel size, not in MB
size...
GForce4 Ti can handle textures up to 4096x4096
pixels.
GForce4 MX can handle textures up to 2048x2048
pixels.
Greater sizes will not work
properly.
You can try the below code. This method doesnot work with applets, but you can
There
are lots of things you can try. The first thing is to use the ImageIO
library to load the image (ImageIO.read(filename)). Another thing you can
try is to use JDK 1.4s ability to memory map files and map your image directly
into memory. This means your map could be in interleaved ARGB fo

Hi
Johan,
I'm
new to Java3d too, but there are two possibilities I know. You can use a 3D
modeller to construct the geometrie, save it to your disk and then use
a file loader to attach it to the scene graph. Here is a link to a file loader

hello Martin,
excuse for the long time for answering, i think your code will be very
useful for us. But I need to understand some basics about Java3D
before.. Anyway, after some time researching and participating this
list, I am sure Java3D can be used for implement our project,
May be it's possible to preload it via one Thread?
So you take no notice of loading the texture.

Do you use texture coordinates
generated earlier or generated by Java3D ?
May be try:
TextureLoader t = new TextureLoader(texPath, "RGB", null);

Hi!
I dont know about spline equations. Try to see in classes source:
com.sun.j3d.utils.behaviors.interpolators.KBCubicSplineSegment
com.sun.j3d.utils.behaviors.interpolators.KBCubicSplineCurve
com.sun.j3d.utils.behaviors.interpolators.CubicSplineSegment

Greetings,
So if this is the case then what are we to expect from the J3D team -
performance enhancements,tools,docs or is SUN going to place their efforts
elsewhere ?

I have tried differenent file formats like gif, bmp and jpg . the.bmp files loads the fastest that is around 40 secs ... which is a 12MB file
Hi,
You can add a new vertex to a geometry array by using by-ref geometry and the valid
vertex count.
As the simplest example, say you start with 4 vertices and want to add one more. If
you use a by-ref aray for your coords you
could make the array size 6 and initialy set the valid vetex count t

You mention "degree project".Does this mean that you are a student or

Alright, I found a method that gives the transform based on the alpha
value, so I've figured that part of it out. However, is there some access
in Java to get the spline equations (I need first and second derivatives at
various points on the splines)?
If not, I assume they must be calculated manu
I've read the kochbart.pdf link that you've sent, and it was quite helpful
in understanding the math behind the interpolator. However, I see a method
in the KBSplinePathInterpolator class called computePathInterpolation, but
it is a protected method. It seems like it is something like this that I
Hi,
That is exactly I did : A Hashtable to store part name as key and
TransformGroup as stored objects.
So I could easily and quickly apply movements to a character in a keyframe
demo.
I always knew what the part were doing what.
I guess OBJ files results in Shape3Ds instead TGs as vrml models do
Doug,
This is excellent news! I've always appreciated the help the Java 3D
team has provided. Java 3D has excellent support.

Yeah, these were the spline classes I was referring to in my email. I read
through the API documentation, but there is very little explanation of the
variables in the KeyFrames. So it's quite difficult to understand how to
construct one of these spline interpolators. If someone has some sample

Hi!
In Java3D is some interpolators for spline animation:
KBRotPosScaleSplinePathInterpolator
KBSplinePathInterpolator
RotPosScaleTCBSplinePathInterpolator
TCBSplinePathInterpolator
Try to use. Read API documentation. Those realy work!

Hi everyone -
I was looking through the spline class that is included in the Java3D API,
and it seems very confusing without much documentation. So I'm not sure if
it's useful at all, or how useful it might be in solving the following
problem.
Given a set of points, I want to be able to create a
