Title: Computer graphics
Inventor: FITZGERALD RAYMOND LEE
IPC: G06T15/04
Filed: 1995-03-31
Abstract: Dynamic computer graphics images are enhanced by mapping two-dimensional texture onto objects with texture definition appropriate to the range from an eye point to the object. With varying definition texture map levels stored, each carrying different texture resolutions (degrees of definition) select sets of levels are paged for mapping operations based on the range to an object. In an operation with two select sets, one set (the top) includes the five least detailed or least defined levels while the other set, the whole, constitutes all levels. The choice between the two select sets for texture mapping an object is determined based on the range, and a specific ratio of pixel view frustum values provides an effective test criteria. <IMAGE>

Patent GB-958882-A (GB)
Abstract: 958,882. Calculating machines; multiplication. ING. C. OLIVETTI & CO. S. p. A. April 17. 1963 [April 24, 1962], No. 15004/63. Heading G4B. In a ten-key multiplying machine the partial products are represented by shaped plates 6, one plate to a multiplicand digit, each having shoulders 9,11 representing units and tens respectively of the multiples of the digit. The plate shown in Fig. 2 is that for the digit one. Pin carriages 12, 76 register the multiplicand and multiplier respectively as entered on a single keyboard. Entering the multiplicand. A set of slides 99 (Fig. 3) beneath the keyboard are-normally positioned so that lugs 101 register with pins 17 of the pin-carriage 12 whereas lugs 102 are intermediate of the pins of carriage 76. Depression of a key rocks the slide 99 and its lug 101 depresses a pin 17. A known escapement mechanism is operated and the carriage shifts to the left, releasing a slide 21 (Fig. 1) until stop 26 is arrested by the depressed pin. The slide 21 sets an indicator drum 28 and differentially positions a vertical slide 34 (all carried by carriage 12) by means of surfaces 31 so that a rod 38 is adjacent one of the partial product plates 6. Entering the multiplier. By a conventional multiplier key the slides 99 are shifted so that lugs 102 register with the pins of the multiplier pincarriage 76 which are set in the usual manner on depression of the number keys. Multiplication. Depression of a multiplication key (not shown) starts the motor. A cam 74 (Fig. 1) rocks a lever 69 so that a set of levers 67 are in the path of the set pins of carriage 76. A cam 81 now operates to actuate pawl 79 (Fig. 2) which backspaces the carriage 76. The set pin of the lowest order rocks one of the levers 67 clockwise which pushes an associated slide 54 into the path of a reciprocating member 83 actuated by cam 92 twice in a machine cycle. The slide 54 has an upward extension 56 by means of which the partial product plates 6 are moved to the right in Fig. 1 and 2 distances depending on the positions of the shoulders 9 or 11 contacted by extension 56. Thus all the plates are moved distances representative of the multiples of the number in the multiplier order being operated on. The rods 38 determine which multiples are transmitted to the totalizers as they have been set to position adjacent the partial product plates appropriate to the multiplicand digits. The rods transmit the motion of plates 6 to actuators 42. The plates 6 are moved twice in a machine cycle. In the first movement the projection 56 on slide 54 engages the shoulders 9 transmitting the units of the partial product. After this the multiplicand carriage 12 is shifted one step to the left and slide 54 is rocked by comb 58 so as to engage the shoulders 11 to transmit the tens of the partial product. Transfer takes place on the return stroke of member 83.
