Abstract
Abstract The invention relates to apparatus for generating a set of patterns (25) suitable for forming a plane tessellation comprising input means (26, 27, 28) for generating a set of lines, processing means (22A, 22B) for modifying the lines, and display means (21) for displaying the result of the modification process. According to the invention the apparatus is characterised in that the processing means comprises line moving and modifying means (22A) for placing the lines in selected relative positions and modifying the lines so as to form a basic pattern, line transformation means (22B) for transforming the lines using selected shapes in a complementary manner so as to transform the basic pattern into a final pattern suitable for tessellation, and replicating means for replicating the final pattern to form the set of patterns.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
Apparatus for generating a set of patterns (25) suitable for forming a plane tessellation comprising input means (1, 2, 11) for generating a set of lines (L1, L2, L3, L4), processing means (3) for modifying said lines, and display means (4, 5) for displaying the result of said modification process, characterised in that said processing means comprises line moving and modifying means (12,13, 14, 15, 16, 17) for placing said lines in selected relative positions and modifying said lines so as to form a basic pattern, line transformation means 14) for transforming said lines using selected shapes in a complementary manner so as to transform said basic pattern into a final pattern suitable for tessellation, and replicating means for replicating said final pattern to form said set of patterns.
Claim 2
Dependent Claim
129 words
Apparatus for generating a set of patterns (25) suitable for forming a plane tessellation comprising input means (1, 2, 11) for generating a set of lines (L1, L2, L3, L4), processing means (3) for modifying said lines, and display means (4, 5) for displaying the result of said modification process, characterised in that said processing means comprises line moving and modifying means (12,13, 14, 15, 16, 17) for placing said lines in selected relative positions and modifying said lines so as to form a basic pattern, line transformation means 14) for transforming said lines using selected shapes in a complementary manner so as to transform said basic pattern into a final pattern suitable for tessellation, and replicating means for replicating said final pattern to form said set of patterns.
Claim 3
Dependent Claim
57 words
Apparatus as claimed in Claim 1 characterised in that said line moving and modifying means comprises means (11, 12) for specifying a fixed end for each line, means (12) for defining the relative positions of said fixed ends, and means (13, 14, 15, 16, 17) for moving said lines relative to each other about said fixed ends.
Claim 4
Dependent Claim
45 words
Apparatus as claimed in either of the preceding claims characterised in that said line transformation means comprises storage means (23) for storing a set of shapes, and selection means for selecting one or more of said shapes for use in transforming said set of lines.
Claim 5
Independent Claim
95 words
A method of generating a set of patterns suitable for forming a plane tessellation comprising generating a set of lines, moving and modifying said lines, and displaying the result of said modification process, characterised in that said moving and modifying step comprises placing said lines in selected relative positions and modifying said lines so as to form a basic pattern, transforming said lines using selected shapes in a complementary manner so as to transform said basic pattern into a final pattern suitable for tessellation, and replicating said final pattern to form said set of patterns.
Claim 6
Independent Claim
95 words
A method of generating a set of patterns suitable for forming a plane tessellation comprising generating a set of lines, moving and modifying said lines, and displaying the result of said modification process, characterised in that said moving and modifying step comprises placing said lines in selected relative positions and modifying said lines so as to form a basic pattern, transforming said lines using selected shapes in a complementary manner so as to transform said basic pattern into a final pattern suitable for tessellation, and replicating said final pattern to form said set of patterns.
Claim 7
Dependent Claim
44 words
A method as claimed in Claim 1 characterised in that said line moving and modifying step comprises specifying a fixed end for each line, defining the relative positions of said fixed ends, and moving said lines relative to each other about said fixed ends.
Claim 8
Dependent Claim
39 words
A method as claimed in Claim 4 or Claim 5 characterised in that said line transformation step comprises storing a set of shapes, and selecting one or more of said shapes for use in transforming said set of lines.
