Detailed Description

Linear interpolation.

Mix first two inputs (a, b) in proportions given by base input (c). Each color channel is processed separately. Equation: x = bc + a(1 - c)

Example:

// Image C
Procedural::TextureBuffer bufferCloud(256);
Procedural::Cloud(&bufferCloud).process();
 
// Image A
Procedural::TextureBuffer bufferGradient(256);
Procedural::Gradient(&bufferGradient).process();
 
// Image B
Procedural::TextureBuffer bufferCell(256);
Procedural::Cell(&bufferCell).setDensity(4).setRegularity(233).process();
 
// Filter
Procedural::Lerp(&bufferCloud).setImageA(&bufferGradient).setImageB(&bufferCell).process();
