Detailed Description

Convert height map to normal map.

Use Sobel algorithm to calculate a normal map out of the given image.

Example:

Procedural::TextureBuffer bufferCell(256);
Procedural::Cell(&bufferCell).setDensity(4).setRegularity(234).process();
Procedural::Normals(&bufferCell).process();

Tip

Create a copy of your working TextureBuffer for normal mapping before you colour it:

// Generate structure
Procedural::TextureBuffer bufferColour(256);
Procedural::Cell(&bufferColour).setDensity(4).setRegularity(234).process();
 
// Create normal map
Procedural::TextureBufferPtr bufferNormalMap = bufferColour.clone();
Procedural::Normals(bufferNormalMap).process();
 
// Colourize structure
Procedural::Colours(&bufferColour).setColourBase(Ogre::ColourValue::Red).setColourPercent(Ogre::ColourValue::Blue).process();
delete bufferNormalMap;
