* Instance of this class represents a connected, flat set of cubes optionally textured as a whole.
|
|
8
|
* (a subset of a NxMx1 cuboid build with 1x1x1 cubes, i.e. the MxNx1 cuboid with arbitrary cubes missing)
|
|
9
|
* <p>
|
|
10
|
* General idea is as follows:
|
|
11
|
* <ul>
|
|
12
|
* <li> Create an instance of this class
|
|
13
|
* <li> Optionally texture it
|
|
14
|
* <li> Apply some effects
|
|
15
|
* <li> Draw it!
|
|
16
|
* </ul>
|
|
17
|
* <p>
|
|
18
|
* The effects we can apply fall into three general categories:
|
|
19
|
* <ul>
|
|
20
|
* <li> Matrix Effects, i.e. ones that change the Cuboid's ModelView Matrix (moves, scales, rotations)
|
|
21
|
* <li> Vertex Effects, i.e. effects that are implemented in the Vertex Shader. Those typically change
|
|
22
|
* the shape of (some sub-Region of) the Cuboid in some way (deforms, distortions, sinks)
|
|
23
|
* <li> Fragment Effects, i.e. effects that change (some of) the pixels of the Texture (transparency, macroblock)
|
|
24
|
* </ul>
|
|
25
|
* <p>
