Illegal Image Size
Hi, having returned to basic J3D bits and bobs for a few years now and I'm having some issues loading a texture.
After having read through a few tutorials I have put together the following code. It simply creates a QuadArray of 4 points, sets the texture coordinates (which I don't know if I have done correct i.e., please note the first parameter, as the method I used to use is deprecated now) then apples and image of 64x64 pixels, a multiple of 2 - which i believe is required by J3D.
private Shape3D loadTexture(){
QuadArray plane =new QuadArray(4,GeometryArray.COORDINATES|GeometryArray.TEXTURE_COORDINATE_2);
Point3f p =new Point3f();
p.set(-1.0f,1.0f,0.0f);
plane.setCoordinate(0,p);
p.set(-1.0f,-1.0f,0.0f);
plane.setCoordinate(1,p);
p.set(1.0f,-1.0f,0.0f);
plane.setCoordinate(2,p);
p.set(1.0f,1.0f,0.0f);
plane.setCoordinate(3,p);
TexCoord2f q =new TexCoord2f();
q.set(0.0f,1.0f);
plane.setTextureCoordinate(0,0,q);
q.set(0.0f,0.0f);
plane.setTextureCoordinate(0,1,q);
q.set(1.0f,0.0f);
plane.setTextureCoordinate(0,2,q);
q.set(1.0f,1.0f);
plane.setTextureCoordinate(0,3,q);
URL textureURL = getClass().getResource(TEXTURE_LOCATION);
TextureLoader loader =new TextureLoader(textureURL,this);
ImageComponent2D image = loader.getImage();
Texture2D texture =new Texture2D();
texture.setImage(0,image);
Appearance appearance =new Appearance();
appearance.setTexture(texture);
Shape3D shape =new Shape3D(plane,appearance);
return shape;
}
Any help working out why I am getting the following exception would be greatly appreciated:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Texture:illegal image size
