====== Sticky Front UV ======

This node performs front projection mapping (classic and perspective camera only).

Optionally it may directly output the UV coordinates to be used in a compositing application for texture mapping. The front projection may happen in releation to the item position at a reference time and will then stick as the item is moved.

===== Controls =====

{{ :dbw:tools:stickyfrontuvnodegui.png?nolink|}}

  * **Camera** The camera to use as a reference for the front projection
  * **Time** Reference time for the front projection, the image will be mapped as if the surfaces where in the position at that time (not taking displacements into account).
  * **Image** The image to map
  * **MipMap Strength** The mip-map strength when mapping the image, higher values cause the image to be more blurry.
  * **Pixel Blending** performs an interpolation on the image pixels when mapping.

===== Outputs =====
{{ :dbw:tools:stickyfrontuvnode.png?nolink|}}
  * **UV** The UV coordinates as a vector, U is stored in X, V in Y, Z is empty. This can easily be hooked up as a colour to export for compositing. \\ This is independent of the mapped image. In fact, no image needs to be selected for the UV output to function.
  * **RGB, Alpha, Luminance** Respectively the colour, alpha or luminance of the mapped image.

===== Notes=====
Displacements (including due to bones) are not taken into account.
