|
504 |
|
|
* For example maps[0] = new Static4D( 0.0, 0.5, 0.5, 0.5 ) sets the 0th component texture map to the
|
505 |

|
* Probably the most common user case would be sending as many maps as there are components in this
|
508 |
|
|
* Mesh. One can also send less, or more (the extraneous ones will be ignored) and set some of them
|
509 |
|
|
* to null (those will be ignored as well). So if there are 5 components, and we want to set the map
|
510 |
|
|
* of the 2nd and 4rd one, call this with
|
511 |
|
|
* maps = new Static4D[4]
|
512 |
|
|
* maps[0] = null
|
513 |
|
|
* maps[1] = the map for the 2nd component
|
514 |
|
|
* maps[2] = null
|
515 |
|
|
* maps[3] = the map for the 4th component
|
516 |
|
|
*
|
517 |
|
|
* A map's width and height have to be non-zero (but can be negative!)
