# Class: l3dprojector

a projector allows textures to be projected on models, orthogonally and perspectively. There is a special texture type that can fix backprojection errors for perpective projection, but shouldnt be used on orthogonal, or if no errors with normal textures appear.

### Method overview:

- activate
- aspect
- attenuate
- backplane
- blend
- deactivate
- fov
- frontplane
- new
- projmatrix
- textureid

new (string name,|l3dlayerid layer|)
  returns: (l3dprojector)
  creates new projector
activate (l3dprojector,int id)
  returns: ()
  adds projector to the active list with given id (0-31)
aspect (l3dprojector,[float])
  returns: (float)
  returns or sets projection aspect ratio = width/height
attenuate (l3dprojector,[boolean])
  returns: (boolean)
  returns or sets attenuation, this is quite heavy effect but will perform a per pixel distance attenuation that causes the projector to fade out towards its backplane.
backplane (l3dprojector,[float])
  returns: (float)
  returns or sets projection backplane distance
blend (l3dprojector,[blendmode])
  returns: (blendmode)
  returns or sets blendmode of projector
deactivate (l3dprojector)
  returns: ()
  removes projector from active list
fov (l3dprojector,[float])
  returns: (float)
  returns or sets projection fov, when negative it will be orthogonal projection with abs(fov) rectangular size
frontplane (l3dprojector,[float])
  returns: (float)
  returns or sets projection frontplane distance
projmatrix (l3dprojector,[matrix4x4])
  returns: ([matrix4x4])
  returns or sets projection matrix. Using frontplane,aspect and so on will override manually set matrices.
textureid (l3dprojector,[texture])
  returns: (texture)
  returns or sets projected texture
