PROCESSES AND METHODS OF OPERATION |
|
67. Image regeneration Image regeneration | The sequence of actions required to regenerate an image from its memory representation |

75. Aiming symbol | A circle or other illuminated shape on the rendering surface used to indicate the area in which the presence of a light pen can currently be detected |
76. Detectable element Detectable element | An output primitive that can be detected by a pointing device |
77. Rubber thread method | Moves the common ends of a set of straight line segments while leaving the other line segment ends fixed |
78. Drawing | Create lines by moving the position input device across the rendering surface, leaving a trail behind it, similar to using a pencil to draw a line on paper. |
79. Towing method | Moving one or more segments along the display surface by shifting them along the path defined by the position input device |
80. Selection | An action aimed at highlighting an image of an output primitive or segment by modifying its visual attributes |
81. Transfer | Offset output primitives by the same vector |
82. Scaling | Enlarge or reduce all or part of the image. Note. Scaling can be carried out optionally with the same factor in all directions |
83. Turn | Rotating output primitives around a given axis |
84. Mirror reflection | Rotating output primitives by 180 around some axis in the plane of the rendering surface |
85. Window | A given part of virtual space |
86. Output field | A specified portion of the visualization space |

88. Clipping | Removing output primitives or parts thereof that lie outside the specified area |
89. Shielding | Suppression of output primitives or parts thereof falling inside a specified region |
90. Scrolling | Moves a window vertically or horizontally so that new data appears inside the output field and old data disappears |
91. Vertical scrolling | Scrolling limited to up and down directions |
92. Zoom | A gradual change in the scale of an image in order to create a visual sensation of movement of the entire visualized group or part of it towards or away from the observer. Note. Scaling factors should be the same in all directions |
93. Tumbling | Dynamic representation of output primitives rotating around an axis whose orientation continuously changes in space |
94. Pan | Gradual transfer of the image in order to create a visual sensation of movement in the horizontal direction. Note. Panning can be limited to the output field |
