* such prepared OutputSurface, the library will make sure to scale any Effects used so that the end |
| 317 | 312 |
* scene will end up looking identical no matter which object we render to. Identical, that is, except |
| 318 | 313 |
* for the loss of quality and gain in speed associated with rendering to a smaller Surface. |
| 314 |
* <p> |
|
| 315 |
* Example: if you create two FBOs, one 1000x1000 and another 500x500 in size, and set the second one |
|
| 316 |
* mipmap to 0.5 (the first one's is 1.0 by default), define Effects to be a single move by (100,100), |
|
| 317 |
* and render a skinned Mesh into both FBO, the end result will look proportionally the same, because |
|
| 318 |
* in the second case the move vector (100,100) will be auto-scaled to (50,50). |
|
| 319 | 319 |
* |
| 320 | 320 |
* @param mipmap The mipmap level. Acceptable range: 0<mipmap<infinity, although mipmap>1 |
| 321 | 321 |
* does not make any sense (that would result in loss of speed and no gain in quality) |
