Method and apparatus for dynamically displaying geo-physical information

Claim 1

A method of forming for display a sequence of images representative of a body at a particular time comprising: providing first and second memories, storing in said first memory a matrix of data bytes representative of locations in a first plane, storing in said second memory a matrix of data bytes representative of locations in a second plane parallel with the first plane, fetching from the first memory the bytes stored therein, converting the fetched bytes into signals usable to produce a display on a video screen and recording the converted signals on a magnetic storage medium, selectively fetching from the first memory a first percentage of the values of data bytes stored therein and from the second memory a second percentage of the values of data bytes stored therein, said first percentage being initially larger than said second percentage, the bytes fetched from the first and second memories representing differing locations distributed throughout the planes, converting the selectively fetched bytes into signals usable to produce a video display and recording the converted signals on the storage medium in sequence after the earlier stored signals; repeating the steps of selectively fetching, converting and sequentially recording while, in each representation, decreasing said first percentage of the bytes from said first memory and increasing said second percentage of the bytes from said second memory until, in the last repetition, said first percentage from said first memory is zero; and displaying the sequence of signals stored on said medium in the manner of a motion picture dissolve to thereby create an illusion of motion through said body.

Claim 2

A method of forming for display a sequence of images representative of a body at a particular time comprising: providing first and second memories, storing in said first memory a matrix of data bytes representative of locations in a first plane, storing in said second memory a matrix of data bytes representative of locations in a second plane parallel with the first plane, fetching from the first memory the bytes stored therein, converting the fetched bytes into signals usable to produce a display on a video screen and recording the converted signals on a magnetic storage medium, selectively fetching from the first memory a first percentage of the values of data bytes stored therein and from the second memory a second percentage of the values of data bytes stored therein, said first percentage being initially larger than said second percentage, the bytes fetched from the first and second memories representing differing locations distributed throughout the planes, converting the selectively fetched bytes into signals usable to produce a video display and recording the converted signals on the storage medium in sequence after the earlier stored signals; repeating the steps of selectively fetching, converting and sequentially recording while, in each representation, decreasing said first percentage of the bytes from said first memory and increasing said second percentage of the bytes from said second memory until, in the last repetition, said first percentage from said first memory is zero; and displaying the sequence of signals stored on said medium in the manner of a motion picture dissolve to thereby create an illusion of motion through said body.

Claim 3

A method of forming a sequence of images representing successive sections within a body at a particular time comprising forming in a first memory a matrix store of bytes defining data points representing points contained in a series of planar regions within the body, each point having identifiable location characteristics and an intensity characteristic; selectively extracting from the first memory a first set of bytes defining a set of data points representing locations lying in a first predetermined planar region in the body which can include points lying in more than one of the stored series of regions and storing the extracted bytes in a second memory; selectively extracting from the first memory a second set of bytes defining a set of data points representing locations lying in a second planar region parallel with the first planar region and storing the second set of bytes in a third memory; converting the bytes stored in the second memory into a signal form displayable on a CRT as a visually perceivable image representative of the first planar region; recording the converted signals on a recording medium; selectively extracting a first percentage of the values of bytes from the data points stored in the third memory and a second percentage of the value of the bytes from the data points stored in the second memory, said first percentage initially being smaller than said second percentage, the extracted bytes from the two memories representing locations in the two planar regions and the total of said first and second percentages equalling substantially 100%; converting the selectively extracted bytes into a signal displayable on a CRT; recording the converted signals on a recording medium; and repeating the steps of extracting, converting the extracted bytes and recording the converted signals a predetermined number of times, each time increasing said first percentage of the value of the bytes extracted from the third memory and decreasing said second percentage of the value of the bytes extracted from the second memory until the second percentage extracted from the second memory is zero, thereby forming on the recording medium a sequence of signal sets displayable as a sequence of images, said sequence of images created by said repeated steps of extracting, converting and recording merging smoothly from the first planar region to the second planar region in the manner of a video dissolve when the recorded converted signals are displayed on a CRT to thereby create an illusion of motion through the body.

Claim 4

A method of forming a sequence of images representing successive sections within a body at a particular time comprising forming in a first memory a matrix store of bytes defining data points representing points contained in a series of planar regions within the body, each point having identifiable location characteristics and an intensity characteristic; selectively extracting from the first memory a first set of bytes defining a set of data points representing locations lying in a first predetermined planar region in the body which can include points lying in more than one of the stored series of regions and storing the extracted bytes in a second memory; selectively extracting from the first memory a second set of bytes defining a set of data points representing locations lying in a second planar region parallel with the first planar region and storing the second set of bytes in a third memory; converting the bytes stored in the second memory into a signal form displayable on a CRT as a visually perceivable image representative of the first planar region; recording the converted signals on a recording medium; selectively extracting a first percentage of the values of bytes from the data points stored in the third memory and a second percentage of the value of the bytes from the data points stored in the second memory, said first percentage initially being smaller than said second percentage, the extracted bytes from the two memories representing locations in the two planar regions and the total of said first and second percentages equalling substantially 100%; converting the selectively extracted bytes into a signal displayable on a CRT; recording the converted signals on a recording medium; and repeating the steps of extracting, converting the extracted bytes and recording the converted signals a predetermined number of times, each time increasing said first percentage of the value of the bytes extracted from the third memory and decreasing said second percentage of the value of the bytes extracted from the second memory until the second percentage extracted from the second memory is zero, thereby forming on the recording medium a sequence of signal sets displayable as a sequence of images, said sequence of images created by said repeated steps of extracting, converting and recording merging smoothly from the first planar region to the second planar region in the manner of a video dissolve when the recorded converted signals are displayed on a CRT to thereby create an illusion of motion through the body.
