Perspective Camera Parameters
View parameters associated with a projection camera
Users can adjust any of the following parameters: field-of-view width, field-of-view height, near clipping plane distance, far clipping plane distance, up vector, and look vector.
The viewing frustum is visualized in a window, allowing students to understand how the parameters relate to the shape of the viewing frustum.
Manipulate the different camera parameters by manipulating the sliders and vector views, or enter numerical values via the numerical entry fields.
Observe how the viewing volume seen in the main window is affected by the parameter changes. In the 3-dimensional scenes, use your right mouse button to manipulate the viewing position.
Clicking along the edges of the viewing area initiates rotation, while clicking in the center of the viewing area initiates a zooming action.
