```
public class Transform3D
extends Object
```
A generalized transform object represented internally as a 4x4 double-precision floating point matrix. The mathematical representation is row major, as in traditional matrix mathematics. A Transform3D is used to perform translations, rotations, and scaling and shear effects.
A transform has an associated type, and all type classification is left to the Transform3D object. A transform will typically have multiple types, unless it is a general, unclassifiable matrix, in which case it won't be assigned a type.
The Transform3D type is internally computed when the transform object is constructed and updated any time it is modified. A matrix will typically have multiple types. For example, the type associated with an identity matrix is the result of ORing all of the types, except for ZERO and NEGATIVE_DETERMINANT, together. There are public methods available to get the ORed type of the transformation, the sign of the determinant, and the least general matrix type. The matrix type flags are defined as follows:
- ZERO - zero matrix. All of the elements in the matrix have the value 0.
- IDENTITY - identity matrix. A matrix with ones on its main diagonal and zeros every where else.
- SCALE - the matrix is a uniform scale matrix - there are no rotational or translation components.
- ORTHOGONAL - the four row vectors that make up an orthogonal matrix form a basis, meaning that they are mutually orthogonal. The scale is unity and there are no translation components.
- RIGID - the upper 3 X 3 of the matrix is orthogonal, and there is a translation component-the scale is unity.
- CONGRUENT - this is an angle- and length-preserving matrix, meaning that it can translate, rotate, and reflect about an axis, and scale by an amount that is uniform in all directions. These operations preserve the distance between any two points, and the angle between any two intersecting lines.
- AFFINE - an affine matrix can translate, rotate, reflect, scale anisotropically, and shear. Lines remain straight, and parallel lines remain parallel, but the angle between intersecting lines can change.
A matrix is also classified by the sign of its determinant:
The Java 3D model for 4 X 4 transformations is:
Note: When transforming a Point3f or a Point3d, the input w is set to 1. When transforming a Vector3f or Vector3d, the input w is set to 0.

  - frustum
```

           double top,
           double near,
           double far)
```
    Creates a perspective projection transform that mimics a standard, camera-based, view-model. This transform maps coordinates from Eye Coordinates (EC) to Clipping Coordinates (CC). Note that unlike the similar function in OpenGL, the clipping coordinates generated by the resulting transform are in a right-handed coordinate system (as are all other coordinate systems in Java 3D).
    The frustum function-call establishes a view model with the eye at the apex of a symmetric view frustum. The arguments define the frustum and its associated perspective projection: (left, bottom, -near) and (right, top, -near) specify the point on the near clipping plane that maps onto the lower-left and upper-right corners of the window respectively, assuming the eye is located at (0, 0, 0).
    
    Parameters:
    left - the vertical line on the left edge of the near clipping plane mapped to the left edge of the graphics window
    right - the vertical line on the right edge of the near clipping plane mapped to the right edge of the graphics window
    bottom - the horizontal line on the bottom edge of the near clipping plane mapped to the bottom edge of the graphics window
    top - the horizontal line on the top edge of the near
    near - the distance to the frustum's near clipping plane. This value must be positive, (the value -near is the location of the near clip plane).
    far - the distance to the frustum's far clipping plane. This value must be positive, and must be greater than near.
  - perspective
```
public void perspective(double fovx,
               double aspect,
               double zNear,
               double zFar)
```
    Creates a perspective projection transform that mimics a standard, camera-based, view-model. This transform maps coordinates from Eye Coordinates (EC) to Clipping Coordinates (CC). Note that unlike the similar function in OpenGL, the clipping coordinates generated by the resulting transform are in a right-handed coordinate system (as are all other coordinate systems in Java 3D). Also note that the field of view is specified in radians.
    
    Parameters:
    fovx - specifies the field of view in the x direction, in radians
    aspect - specifies the aspect ratio and thus the field of view in the x direction. The aspect ratio is the ratio of x to y, or width to height.
    zNear - the distance to the frustum's near clipping plane. This value must be positive, (the value -zNear is the location of the near clip plane).
    zFar - the distance to the frustum's far clipping plane
  - ortho
```
public void ortho(double left,
         double right,
         double bottom,
         double top,
         double near,
         double far)
```
    Creates an orthographic projection transform that mimics a standard, camera-based, view-model. This transform maps coordinates from Eye Coordinates (EC) to Clipping Coordinates (CC). Note that unlike the similar function in OpenGL, the clipping coordinates generated by the resulting transform are in a right-handed coordinate system (as are all other coordinate systems in Java 3D).
    
    Parameters:
    left - the vertical line on the left edge of the near clipping plane mapped to the left edge of the graphics window
    right - the vertical line on the right edge of the near clipping plane mapped to the right edge of the graphics window
    bottom - the horizontal line on the bottom edge of the near clipping plane mapped to the bottom edge of the graphics window
    top - the horizontal line on the top edge of the near clipping plane mapped to the top edge of the graphics window
    near - the distance to the frustum's near clipping plane (the value -near is the location of the near clip plane)
    far - the distance to the frustum's far clipping plane
