The HPS::CameraControl class is a smart pointer that is tied to a database object. The CameraControl is used to manipulate the viewpoint, or camera, in a scene. Using this control, the view position, orientation, target, and aspect ratio of a segment's camera can be set. Cameras are considered segment attributes, but unlink other attributes, they inherit as a group down the segment hierarchy. This table lists default values for the various segment attributes accessible from HPS::CameraControl. More...

override void | Dispose () |
HPS.CameraControl | Dolly (float in_x_dir, float in_up, float in_forward) |
Moves the camera position and target the specified amount but maintains the up vector and field. If a complete camera is not already set up, one will be populated with default values before dollying. More... | |
override HPS.Type | ObjectType () |
This function returns the type the object, as declared. This does not necessarily give the true type of the underlying object. More... | |
HPS.CameraControl | Orbit (float in_theta, float in_phi) |
Moves the camera around the target in_theta degrees to the right and in_phi degrees up. The target and field are maintained but position and up_vector may change. If a complete camera is not already set up, one will be populated with default values before orbiting. More... | |
HPS.CameraControl | Pan (float in_theta, float in_phi) |
Pivots the camera on its location in_theta degrees to the right and in_phi degrees up. The position and field remain unchanged while the target and up vector may change. If a complete camera is not already set up, one will be populated with default values before panning. More... | |
HPS.CameraControl | Roll (float in_theta) |
Spins the camera around its target in_theta degrees counter-clockwise (the scene will appear to move clockwise). The position, field, and target are unchanged while the up-vector may change. If a complete camera is not already set up, one will be populated with default values before rolling. More... | |
HPS.CameraControl | SetField (float in_width, float in_height) |
Sets the camera field. More... | |
HPS.CameraControl | SetNearLimit (float in_double) |
Sets the near_limit to in_double that defines the near limit of the camera. A value approaching 0.0 will place it close to the camera position (at the cost of poor z-buffer precision), whereas a value approaching 1.0 will place it near the camera target (at the cost of clipping away anything closer than the target). A value exactly equal to 0 will let HOOPS Visualize choose a limit based on the precision of the zbuffer as reported by the driver. More... | |

HPS.CameraControl | UnsetEverything () |
Removes all settings from this object. Unlike other attributes, it is not possible to unset just a single field of a camera. More... | |
HPS.CameraControl | Zoom (float in_zoom) |
Adjusts the field of view by dividing the width and height by the input value. Numbers greater than one will have the effect of making things on screen appear larger. Numbers between zero and one will have the opposite effect. Only the field is affected. If a complete camera is not already set up, one will be populated with default values before zooming.
