Hello;

Is there any noise function exactly same as turbluance noise in VEX (with fraquency adjustment parameter)?


Thanks.

it depends on noise type, you can check the code produced by the attribvop (RMB/VEX_VOP Options/View VEX Code)

so for example for Aligator noise you can use:
vector freq = {2,2,2};
vector off = {0,0,0};
float amp = 3;
float rough = 0.5;
float atten = 1;
int turb = 5;


// float noise
// v@Cd = amp*anoise(v@P*freq - off, turb, rough, atten);

// vector noise
v@Cd = anoise(v@P*freq - off, turb, rough, atten);
v@Cd *= amp;

for Simplex noise:
#include <voplib.h>
vector freq = {2,2,2};
vector off = {0,0,0};
float amp = 3;
float rough = 0.5;
float atten = 1;
int turb = 5;

// float noise
// v@Cd = vop_simplexNoiseVF(v@P*freq - off, turb, amp, rough, atten);

// vector noise
v@Cd = vop_simplexNoiseVV(v@P*freq - off, turb, amp, rough, atten);


etc…
