* Sometimes we want to display a Mesh on a rectangular screen. Then we need to stretch it by |
|
| 227 |
* different factors in x and y (or z) directions. If we also wanted do display some vertex effects |
|
| 228 |
* done on this mesh, let's say a bulge done by a Distort effect, and wanted the bulge to be round, |
|
| 229 |
* (i.e the same in x and y directions) then doing so without this method would be impossible. |
|
| 230 |
* |
|
| 231 |
* This sets 'stretch' factors in each 3 dimensions. All vertices of this Mesh will be premultiplied |
|
| 232 |
* by those factors in the very first line of the Vertex Shader, before any Effects are done on it. |
|
| 233 |
* Using this we can thus pre-stretch the mesh to aspect ratio equal to the surface we eventually |
|
| 234 |
* want to display the Mesh on, and this way we can achieve a round Distort bulge! |
|
| 235 |
* |
|
| 236 |
* This could also be used to pre-stretch a Rectangles Mesh to a size equal (in pixels) to the bitmap |
|
| 237 |
* this mesh is textured with - and this lets us work with all Effects in natural, pixel units. |

|
