|
|
17 | * A mesh is a regular grid representing cells of the same width (in x) and of the same height | |
|
|
18 | * (in y). At each mesh point is associated a value. | |
|
|
19 | * | |
|
|
20 | * Each axis of the mesh is defined by a minimum value, a number of values is a mesh step. | |
|
|
21 | * For example: if min = 1, nbValues = 5 and step = 2 => the axis of the mesh will be [1, 3, 5, | |
|
|
22 | * 7, 9]. | |
|
|
23 | * | |
|
|
24 | * The values are defined in an array of size {nbX * nbY}. The data is stored along the X axis. | |
|
|
25 | * | |
|
|
26 | * For example, the mesh: | |
|
|
27 | * Y = 2 [ 7 ; 8 ; 9 | |
|
|
28 | * Y = 1 4 ; 5 ; 6 | |
|
|
29 | * Y = 0 1 ; 2 ; 3 ] | |
|
|
30 | * X = 0 X = 1 X = 2 | |
|
|
31 | * | |
|
|
32 | * will be represented by data [1, 2, 3, 4, 5, 6, 7, 8, 9] | |
