.SH "Detailed Description"
.PP 
Engine for computing a normal map from a height map\&. 

This engine will create a normal map texture from a height map texture\&. You can use it in an Inventor file like this:
.PP
.PP
.nf
Texture2 {
  image = HeightMapToNormalMap {
    sourceImage = Texture2 { filename "HeightMap\&.jpg" } \&. image
  } \&. image
}
.fi
.PP
.PP
Be aware that the field connections will remain active, so both Texture2 nodes and the HeightMapToNormalMap engine will be kept resident in memory (unless you intervene manually and detach the engine) even though only the 'outer' Texture2 node is needed\&. This can give quite a big memory use overhead\&.
.PP
Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor \fBv2\&.1\fP API\&.
