* Names of Effects one can add to the DistortedEffects queues.

* <p>
|

|
|
* Effect's 'Uniforms' are a vector of 7 (matrix effects) 12 (vertex) or 8 (fragment) floats, which
|
| 31 |
|
|
* together form full information how to compute a given effect.
|
| 32 |
|
|
* Typically, some of those values will be Interpolated in CPU (by one of the 'EffectQueueX.compute()'
|
| 33 |
|
|
* methods) and the effect of such Interpolation sent to the Shaders.
|
| 34 |
|
|
* </p>
|
| 35 |
|
|
* <p>
|
| 36 |
|
|
* Effect's 'Unity' is such a particular vector of its 'interpolated values' which makes the
|
| 37 |
|
|
* effect NULL. For example, if the effect is 'MOVE' by a 3-dimensional vector, then a 'NULL
|
| 38 |
|
|
* MOVE' is a MOVE by vector (0,0,0), thus (0,0,0) is the unity of the MOVE effect.
|
| 39 |
|
|
* This is used by the EffectQueue classes to decide if the final form of the Effect is NULL - and
|
| 40 |
|
|
* thus if it can safely be removed from Effect Queues without affecting the visual in any way.
