This method of the Direct3dRMViewport Class sets the dimensions of the viewport on the front clipping plane, relative to the camera's z-axis.
public void setPlane(float left, float right, float bottom, float top);
left | The minimum x-coordinate of the four sides of the viewport. |
right | The maximum x-coordinate of the four sides of the viewport. |
bottom | The minimum y-coordinate of the four sides of the viewport. |
top | The maximum y-coordinate of the four sides of the viewport. |
Unlike the setField method, which specifies a centered proportional viewport, this method enables you to specify a viewport of arbitrary proportion and position. For example, this method could be used to construct a sheared viewing frustum to implement a right- or left-eye stereo view.
