describes a 4x4 matrix transformation
<p>
A <a class="el" href="a01207.html" title="describes a 4x4 matrix transformation">vtkPerspectiveTransform</a> can be used to describe the full range of homogeneous transformations. It was designed in particular to describe a camera-view of a scene. <p>
The order in which you set up the display coordinates (via <a class="el" href="a01207.html#e9d12accf4e0d0f22835748e7ba6598d">AdjustZBuffer()</a> and <a class="el" href="a01207.html#a194dbd61adb47346d6ea4be5a437c52">AdjustViewport()</a>), the projection (via <a class="el" href="a01207.html#008d9581e44a1eba7cb4c1372c4f56ce">Perspective()</a>, <a class="el" href="a01207.html#470bc814f0babb4b8a4e8518f756b1e9">Frustum()</a>, or <a class="el" href="a01207.html#6737cca34ecda7c69e1d4f6cf1d31b34">Ortho()</a>) and the camera view (via <a class="el" href="a01207.html#c4635f9615090e4f7b77efcf237e8636">SetupCamera()</a>) are important. If the transform is in PreMultiply mode, which is the default, set the Viewport and ZBuffer first, then the projection, and finally the camera view. Once the view is set up, the Translate and Rotate methods can be used to move the camera around in world coordinates. If the Oblique() or <a class="el" href="a01207.html#66a490460ac48b589c6921a93ecefc99">Stereo()</a> methods are used, they should be called just before <a class="el" href="a01207.html#c4635f9615090e4f7b77efcf237e8636">SetupCamera()</a>. <p>
In PostMultiply mode, you must perform all transformations in the opposite order. This is necessary, for example, if you already have a perspective transformation set up but must adjust the viewport. Another example is if you have a view transformation, and wish to perform translations and rotations in the camera's coordinate system rather than in world coordinates. <p>
The SetInput and Concatenate methods can be used to create a transformation pipeline with <a class="el" href="a01207.html" title="describes a 4x4 matrix transformation">vtkPerspectiveTransform</a>. See <a class="el" href="a01723.html" title="describes linear transformations via a 4x4 matrix">vtkTransform</a> for more information on the transformation pipeline. <dl class="see" compact><dt><b>See also:</b></dt><dd><a class="el" href="a00577.html" title="allows operations on any transforms">vtkGeneralTransform</a> <a class="el" href="a01723.html" title="describes linear transformations via a 4x4 matrix">vtkTransform</a> <a class="el" href="a00998.html" title="represent and manipulate 4x4 transformation matrices">vtkMatrix4x4</a> <a class="el" href="a00227.html" title="a virtual camera for 3D rendering">vtkCamera</a></dd></dl>

Create a shear transformation about a plane at distance z from the camera. The values dxdz (i.e. dx/dz) and dydz specify the amount of shear in the x and y directions. The 'zplane' specifies the distance from the camera to the plane at which the shear causes zero displacement. Generally you want this plane to be the focal plane. This transformation can be used in combination with Ortho to create an oblique projection. It can also be used in combination with Perspective to provide correct stereo views when the eye is at arbitrary but known positions relative to the center of a flat viewing screen.

Create a stereo shear matrix and concatenate it with the current transformation. This can be applied in conjunction with either a perspective transformation (via Frustum or Projection) or an orthographic projection.

The angle should be negative for the left eye, and positive for the right. This method works via Oblique.
