### Transforming Textures and Objects

When an object is transformed all textures attached to the object at that time are transformed as well. This means that if you have a `translate`, `rotate`, `scale`, or `matrix` modifier in an object before a texture, then the texture will not be transformed. If the transformation is after the texture then the texture will be transformed with the object. If the transformation is inside the `texture` statement then only the texture is affected. The shape remains the same. For example:

     sphere { 0, 1

      texture { Jade } // texture identifier from TEXTURES.INC

      scale 3      // this scale affects both the

               // shape and texture

     }

     sphere { 0, 1

      scale 3      // this scale affects the shape only

      texture { Jade }

     }

     sphere { 0, 1

      texture {

       Jade

       scale 3     // this scale affects the texture only

      }

     }

Transformations may also be independently applied to pigment patterns and surface normal patterns. Note that scaling a normal pattern affects only the width and spacing. It does not affect the apparent height or depth of the bumps. For example:

     box { <0, 0, 0>, <1, 1, 1>

      texture {

       pigment {

        checker Red, White

        scale 0.25 // This affects only the color pattern

       }

       normal {

        bumps 0.3 // This specifies apparent height of bumps

        scale 0.2 // Scales diameter and space between bumps

              // but not the height. Has no effect on

              // color pattern.

       }

       rotate y*45 // This affects the entire texture but

      }       // not the object.

     }
