Hello,
I applied a grayscale image with 24bit as a texture to a simple quad. it
works perfect but looks bad. the image seems to be color reduced. it is not
dithered or have compression artefacts but have blocklike structures. it
might have 256 colors? has anybody a solution or idea?
//create geometry
QuadArray qa =
new QuadArray(8,
QuadArray.COORDINATES
| QuadArray.TEXTURE_COORDINATE_2
| QuadArray.NORMALS);
//...
//load an image
tk = java.awt.Toolkit.getDefaultToolkit()
tk.getImage(filename)
//create the texture
Appearance app = new Appearance();
app.setCapability(Appearance.ALLOW_TEXTURE_WRITE);
app.setCapability(Appearance.ALLOW_TEXTURE_READ);
TextureAttributes texAttr = new TextureAttributes();
app.setTextureAttributes(texAttr);
Material mm = new Material();
mm.setLightingEnable(false);
app.setMaterial(mm);
app.setColoringAttributes(
new ColoringAttributes(
new Color3f(1.0f, 1.0f, 1.0f),
//ColoringAttributes.FASTEST));
ColoringAttributes.NICEST));
imageSwitch.addChild(new Shape3D(qa, app));
the code is copy and paste from various locations in my code,
maybe some lines are missing.
does anyone see the fault?
thanks for help!
Chris
