hi, do I have to activate this clipping for every Shae3D seperately, with the help of a PolygonAttributes-object, or is there a central way of doing it?

hi, I use shading like described in the thread "shading" (the normal way).
But I noticed that flat-shading is used so I tried to activate smooth goraud-shading. I created an ColoringAttributes-object, used setShadeModel(ColoringAttributes.SHADE_GOURAUD) and added it to the object's  Appearance. But no difference can be seen.
So thx for help

thank you very much arne, it finally works now
I forgot to add normals
thx & cu

it doesn't work. Is it really that complicated to use simple shading in Xith? Has noone ever used it succesfully? In poor openGL it's quite simple. It seems I have to use it directly.

hi & thx. I'm trying it on Monday, althoug I don't know how that influences shading.
cu

I played a bit with the settings but none did what I wanted them to do

hi & thx for your answer.
I use the normal HelloXith3D-demo with a light:

PointLight l=new PointLight();
l.setEnable(true);
l.setColor(new Color3f(1,0,0));
l.setLocation(new Point3f(0,0,4f));
scene.addChild(l);


and the cube with some attributes:

Geometry geo = Cube.createCubeViaTriangles(0, 0, 0, 1, true);        
           Appearance ap=new Appearance();            
           Material m=new Material(true);
           m.setDiffuseColor(1,0.5f,0.5f);
           m.setEmissiveColor(new Color3f(1,0.5f,0.5f));
           m.setShininess(0.9f);
           m.setSpecularColor(1,0.5f,0.5f);            
           ap.setMaterial(m);            
           ColoringAttributes ca=new ColoringAttributes(new Color3f(1,0.5f,0.5f), ColoringAttributes.SHADE_FLAT);
           ap.setColoringAttributes(ca);
           Shape3D sh=new Shape3D(geo, ap);

hi, I tried to use shading in my small program. It is actually the HelloXith3D-code. I deactivated the colors of the cube, put a PointLight to the cam's position and enabled lighting  in the cube's material and in the RenderAttributes of the canvasPeer.
Now the cube is lit in a nice red light but without shading. You can't see the edges in front of the cam. It's like one level surface that is now red.
I belive someone here can help me,
thx & cu

itistoday, no stress. it's not that due. I just meant it would be great if u completed it somewhen in the near future. thank u for your engagement :]

hi & thx to all.
itistoday, pls hurry
we need it for our college-project. Otherwise our professor will tear our bodies in small pieces

hi and thx.
for normal nodes it works well, but e.g. when I want to make a copy of a md2-model I can see 2 figures, but they always have the same animation at the same time  .
Maybe I find a way to solve the prob.
If someone knows anythinh, pls tell me, thx, cu

hi, ich tried to render 1 Shape3D at 2 different positions. Xith just draw it once. So I tried the Link-class and the SharedGroup. But it didn't work either.
1) I created my scene
2) I put a TransformGroup (t1) at the scene
3) and a second one (t2) at the scene, too
4) I created a SharedGroup (sg) and gave it my Shape3D as child
5) I put a Link under t1 and gave it sg
6) and a second link under t2
Now Xith only draws the Shape3D at the position that is located last.
What am I gonna do?
Thx 4 help, cya

ok, thx, that helped a lot

ok, thx. Does Xith create such volumes also when the object is created with the 3ds or md2 loader?
thx, cu

hi, does Xith cull (frustrum culling) by default?
So when I add some objects (spheres, boxes,...) does Xith make a bounding-volume around theese objects by itself and then culls them, or do I have to create the boundings?
thx, cu

hi, is it possible, to make a kind of bounding-group?
E.g., I have a couple of trees and because Xith should not cull (frustrum culling) every tree, I want to have one bounding-volume around all the trees.
Thx, cu

hi and thx for all

@kul_th_las:
this is a good idea, but so I need control of each frame within the animations. I don't know much about animation, but I wanted to use the AseFile from Xith. I saw a commnd like 'setAnimation("name");'. I thougt, this way, I would just start the animation. And the animation controlls the single frames to be shown.

Hi, how do I make a deep copy (not just a reference) of a loaded model (i.e. a creature)?
When I want to show 2 creatures of the same kind, one jumping and one walking, I need to have 2 copies of the original model.
Pls, tell me how, or if there r better ways in solving my problem.
Thx, cu

u don't have to get the matrix back.
There r very effective calls in openGL directly for rotation, translation and scaling: glRotate, glTranslate and glScale. But theese commands r never used by Xith. Xith itself calculates a matrix and sends it to openGL by the much less efficient method glMultMatrix.
So, when I have to change (move, rotate) 100 objects in my scene the CPU has to do all the transformations, possibly hundreds.
Normally in openGL u walk through your scenegraph and call glRotate....

hi, y the hell, does Xith let the CPU do the matrix calculations and not openGL and the GFX-Card??
For example in the Class Transform3D:

private MatrixExt4f matrix = null;

public void rotX(float angle) {
       setIdentity();
       matrix.rotX(angle);
}

MatrixExt4f is a subclass from Matrix4f from the package javax.vecmath.

One of the main advantages of today's GFX-Cards is that they do all the expensive calculations.
Pls, someone help me
