Is it possible to animate vectron values in its script?

[foliohattu]

im Wondering if its possible to animate vectron script values by adding a key framable slider or altering its script to say that in x number of frames the number should be x ?

Trying to think a way to animate following numbers on menger sponge boolen.
Mainly the 2.1 and 3.2

vector a = mod( p*s, 2.1 )-1.0;
s *= 3.0;
vector r = abs(1.0 - 3.2*abs(a));

Does anyone know if this is possible?

Hi,
you can use the time parameter, please have a look at this example:

Code: Select all

 #include "octane-oslintrin.h"
shader OslGeometry(
    int Iterations = 10,
    float Power = 2.0,
    float Bailout = 20,
    output _sdf c = _SDFDEF)
{
    vector pos = P;

    float power = Power;

    float w = fmod(_wipes(), 300.0) / 300.0;

    w += time / 300.0;

    power = w * 5 + 5.0;

	vector z = P;
	float dr = 1.0;
	float r = 0.0;
	for (int i = 0; i < Iterations ; i++) {
		r = length(z);
		if (r>Bailout) break;
		
		// convert to polar coordinates
		float theta = acos(z[2]/r);
		float phi = atan2(z[1],z[0]);
		dr =  pow( r, power-1.0)*power*dr + 1.0;
		
		// scale and rotate the point
		float zr = pow( r,power);
		theta = theta*power;
		phi = phi*power;
		
		// convert back to cartesian coordinates
		z = zr*vector(sin(theta)*cos(phi), sin(phi)*sin(theta), cos(theta));
		z+=pos;
	}
	c.dist = 0.5*log(r)*r/dr;
}

ciao Beppe

float w = fmod(_wipes(), 300.0) / 300.0;

Could you tell me the purpose of this line, and what the function _wipes() does, is for? Having real trouble getting this to work properly. More info on how the time variable works is very much needed. Also, any other undocumented variables we should know about?
