* This class is similar to CardMaker, but instead of generating ordinary
|
||
|
|
* cards, it generates a circular rose that represents the projection of a 3-D
|
||
|
|
* scene through a fisheye lens. The texture coordinates of the rose are
|
||
|
|
* defined so that each 2-D vertex has a 3-D UVW that reflects the
|
||
|
|
* corresponding position in 3-D space of that particular vertex.
|
||
|
|
*
|
||
|
|
* This class is particularly suited for converting cube maps to sphere maps.
