[Bf-blender-cvs] CVS commit: blender/source/blender/blenkernel/intern node_composite.c

[Ed Halley]

broken,

The build stops on a missing CMP_NODE_DISPLACE - did you forget to  
commit
BKE_node.h?  I could guess the new #define should be 245 but...

   Log:
   == Compositor ==
   * Displace Node

   Displaces an input image's pixels based on an input vector mask.  
This can be
   useful for a lot of things, like hot air distortion, quick-and- 
dirty compo
   refraction, compositing live footage behind refracting objects,  
and more!

   The amount of displacement in the X and Y directions is determined  
by:
   * The value of the mask's channels
     - (red) channel 1's value determines displacement along the  
positive or
     negative X axis
     - (green) channel 2's value determines displacement along the  
positive or
     negative Y axis

   If both the channel's values are equal (i.e. a greyscale image)  
the input
   image will be displaced equally in both X and Y directions, also  
according to:
   * The X scale and Y scale buttons
     - These act as multipliers to increase or decrease the strength  
of the
     displacement along their respective axes. They need to be set to  
non-zero
     values for the node to have any effect.

   Because of this, you can use the displace node in two ways, with a  
greyscale
   mask(easy to paint, or take from a procedural texture), or with a  
vector
   channel or RGB image, such as a normal pass, which will displace  
the pixels
   based on the normal direction.
