|
* All Objects to which Distorted Graphics effects can be applied need to be extended from here.
|
40
|
* <p>
|
41
|
* General idea is as follows:
|
42
|
* <ul>
|
43
|
* <li> Create an instance of (some class descended from) DistortedObject
|
44
|
* <li> Paint something onto the Bitmap that's backing it up
|
45
|
* <li> Apply some effects
|
46
|
* <li> Draw it!
|
47
|
* </ul>
|
48
|
* <p>
|
49
|
* The effects we can apply fall into three general categories:
|
50
|
* <ul>
|
51
|
* <li> Matrix Effects, i.e. ones that change the Bitmap's ModelView Matrix (moves, scales, rotations)
|
52
|
* <li> Vertex Effects, i.e. effects that are implemented in the Vertex Shader. Those typically change
|
53
|
* the shape of (some sub-Region of) the Bitmap in some way (deforms, distortions, sinks)
|
54
|
* <li> Fragment Effects, i.e. effects that change (some of) the pixels of the Bitmap (transparency, macroblock)
|
55
|
* </ul>
|
56
|
* <p>
|
57
|
* Just like in DistortedNode and DistortedFramebuffer, we need to have a static list of all
|
58
|
* DistortedObjects currently created by the application so that we can implement the 'mark for
|
59
|
* deletion now - actually delete on next render' thing.
|
60
|
* We need to be able to quickly retrieve an Object by its ID, thus a HashMap.
