    1 GIMP normalmap plugin
    2 (C) 2002-2008 Shawn Kirst <skirst@insightbb.com>
    3 ==========================================
    4 
    5 This is a plugin for GIMP version 2.4.x. It allows you to convert images into
    6 RGB normal maps for use in per-pixel lighting applications. The goal is to
    7 completely clone NVIDIA's photoshop plugin, with a few new useful features.

    9 Features
   10 ==========================================
   11 * Filters. These include the filters found in the NVIDIA plugin (4
   12 sample, 3x3, 5x5, 7x7 and 9x9) with the addition of a 3x3 sobel and a 3x3
   13 prewitt filter (yields the best results IMO).
   14 * Post-filtering normal scaling
   15 * Wrap mode. This allows the filters to wrap around the image.
   16 Useful for creating normalmaps from a tiling bumpmap.
   17 * Height source. Use an average of the RGB components or the alpha
   18 channel as the height source in the generation of the normals.
   19 * Alpha result. For RGBA images, the alpha channel can either remain
   20 unchanged, have the height used to generate the normal written to it, be
   21 replaced by either 0 or 1, or the value of a grayscale image.
   22 * Dynamic 2D preview in the interactive dialog.
   23 * Dynamic 3D preview window with the normalmap applied to a lit primitive
   24 * Parallax bump mapping for 3D preview

   26 Planned features

   28 * Support gray and gray-alpha images.
