please see the attachement. I want to let the icon's black background
be transparent,  and do a setTransparent(0) on the icon. the result
is the icon seems faded than before, how can I keep it as before ?
thanks.

ah, yes. I do a calcNormals(), and it shows up. thanks.

I do a setTexture on my model , and setup keyframe animation for it,
but after animate, the model become black, seems lost its texture ,
how can I keep the texture ? should re setTexture after each frame ?
thanks.

yes.  I am using intel onboard chips.
is there a software way to do anti-alias ?

I try this.

buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_GL_AA_4X);


and the result  seems the same.  am I missing something others ?

see the attachment.

by the way, I also tested my app with jPCT desktop version.
does code

buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_HARDWARE_ONLY);


will enable anti-alias ? the result seems no effect.
look the attach image

thanks. I will check this.

jPCT loads texture coordinates and names from 3DS as well as diffuse colors (but only if there are no textures assigned). Everything else will be ignored.
If the file contains diffuse colors but still comes out black, have a look at the log output. Diffuse colors can exist in two different formats. The file itself doesn't contain any information about which one it uses, so jPCT has to guess. However, some exporters create diffuse color information that i couldn't make any sense of.
If this is the case, this will be written to the log.

here is the log, there has a line " I/jPCT-AE ( 3464): Texture named RCA_orig.jpg added to TextureManager!"
seems like jPCT-AE find a texture in the model file, but my colleague said he doesn't mapping any texture. strange.

My colleague have made  a model for me. He only apply some material to the model, and not texture.
the model looks realistic  in Cinema 4D. and he export the model to .3ds file, and I load this file to jPCT,
the model looks black in jPCT,   how can I make it looks realistic as it in Cinema 4D ? thanks.

You can't. It isn't supported on ES 1.0 as far as i know.

thanks. so what's the minimum ES version should I get ?
or is there any other way to implement it ?

hi,  my app will run on a custom hardware, and it only support opengl es 1.0,
so how should  I implement anti-alias on my app with jPCT-AE ? thanks.

thanks. this is exactly what I want.

x=4 is no axis. I'm not sure what you are after...maybe setRotationPivot() is more what you want?

oh, I mean a line parallel to Y axis and pass through  point (4,0,0). how can I rotate around this ?

http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Object3D.html#rotateAxis(com.threed.jpct.SimpleVector, float)
if I use this api,  how should I represent a axis  (for example  x=4)  in vector form ? thanks.

I use the following code to project a vertex to screen, and the following output seems not what I want.
the mesh belong to a object which has a parent dummy object, I have scale and transfer the parent dummy object  to let
the object totally visible in the screen.  my question is how can I project a vertex which belong to a dummy object's son object ? sorry for my poor english.

public class VertexInfo extends GenericVertexController {

@Override
public void apply() {
// TODO Auto-generated method stub
SimpleVector[] sv = this.getSourceMesh();
Logger.log("mesh");
for(int i=0; i<sv.length; i++){
Logger.log(sv[i].toString());
}
// sort out the topLeftVertex
mMesh = new SimpleVector[sv.length];
for(int i=0; i<sv.length; i++){
mMesh[i] = SimpleVector.create(sv[i]);
}
}
private SimpleVector[] mMesh = null;
public SimpleVector getTopLeftVertex(Camera cam, FrameBuffer fb){

SimpleVector s = new SimpleVector();
for(int i=0; i<mMesh.length; i++){

SimpleVector sv = Interact2D.project3D2D(cam, fb, mMesh[i]);
Logger.log("project "+mMesh[i].toString()+" to "+sv.toString());
if(sv.x <= s.x && sv.y <= s.y){
s = SimpleVector.create(sv);
}

}
return s;
}

}

the output goes here:
