// Persistence Of Vision Ray Tracer POV-Ray 3.5 sample Scene

// PYRAMID.POV demonstrates basic use of macros and local
// identifiers in recursive calls. Creates a fractal
// pyramid from spheres.
//
// Note some spheres are redundant. See PYRAMID2.POV
// for a version which eliminates duplicate spheres.


// Define the macro. Parameters are:
// X: position of sphere
// Y: position of sphere
// Z: position of sphere
// R: radius of sphere
// L: level of recursion
#macro Pyramid(X,Y,Z,R,L)

sphere { ,R}

#if (L > 0)
#local New_L = L - 1;
#local New_R = R / 2;
#local Pos = New_R * 3;
