I am trying to place different textures on sides of a Box
, but without any success.
Here is my code:
BufferedImage texture1 = ...; // brown image
BufferedImage texture2 = ...; // green image
Box box = new Box(1f, 1f, 1f, Box.GENERATE_TEXTURE_COORDS, new Appearance());
TextureAttributes ta = new TextureAttributes();
ta.setTextureMode(TextureAttributes.MODULATE);
Appearance app = new Appearance();
app.setTexCoordGeneration(new TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR, TexCoordGeneration.TEXTURE_COORDINATE_2));
app.setTexture(new TextureLoader(texture1).getTexture());
app.setTextureAttributes(ta);
box.setAppearance(Box.TOP, app);
Appearance app2 = new Appearance();
app2.setTexCoordGeneration(new TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR, TexCoordGeneration.TEXTURE_COORDINATE_2));
app2.setTexture(new TextureLoader(texture2).getTexture());
app2.setTextureAttributes(ta);
box.setAppearance(Box.RIGHT, app2);
Result:
Well, it places the images on both sides, but as you can see, they are blured.
I thought it could be caused by wrong TexCoordGeneration
applied to the appearance of sides. But I am also not sure if I create the Box
instance with correct parameters.
How should I fix this?
Thank you very much for answers!
OK I fixed that by generating my own TexCoordGeneration
object with Vector4f
objects.
Code:
app.setTexCoordGeneration(this.generateTexCoord(box.getShape(Box.TOP)));
and the method generateTexCoord()
:
private TexCoordGeneration generateTexCoord(Shape3D shape) {
BoundingBox bb = new BoundingBox(shape.getBounds());
Point3d lower = new Point3d();
Point3d upper = new Point3d();
bb.getLower(lower);
bb.getUpper(upper);
double width = upper.x - lower.x;
double height = upper.y - lower.y;
double deep = upper.z - lower.z;
Vector4f planeX = new Vector4f((float)(1.0/width), 0.0f, 0.0f, (float)(-lower.x/width));
Vector4f planeY = new Vector4f(0.0f, (float)(1.0/height), 0.0f, (float)(-lower.y/height));
Vector4f planeZ = new Vector4f(0.0f, 0.0f, (float)(1.0/deep), (float)(-lower.z/deep));
TexCoordGeneration tcg = new TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR, TexCoordGeneration.TEXTURE_COORDINATE_2);
if(width == 0) { // RIGHT, LEFT: YZ
tcg.setPlaneS(planeZ);
tcg.setPlaneT(planeY);
} else if(height == 0) { // TOP, BOTTOM: XZ
tcg.setPlaneS(planeX);
tcg.setPlaneT(planeZ);
} else { // FRONT, BACK: XY
tcg.setPlaneS(planeX);
tcg.setPlaneT(planeY);
}
return tcg;
}
Hope that helped someone with same problem. :)
I had the same problem as you and I was reading pages on the internet and with everything I finished the cube with different textures. I used images from my computer. Hope it works for everybody, it took me 3 days!
