  POV-Ray 3.6 Documentation Online View Adding a Camera Adding Texture to an Object Describing an Object

Now that the camera is set up to record the scene, let's place a yellow sphere into the scene. We add the following to our scene file:

  sphere {
    <0, 1, 2>, 2
    texture {
      pigment { color Yellow }

The first vector specifies the center of the sphere. In this example the x coordinate is zero so it is centered left and right. It is also at y=1 or one unit up from the origin. The z coordinate is 2 which is five units in front of the camera, which is at z=-3. After the center vector is a comma followed by the radius which in this case is two units. Since the radius is half the width of a sphere, the sphere is four units wide. Adding a Camera Adding Texture to an Object
