Sample Sphere VEX

[andrulis]

Hi there! how to use Sample Sphere vex node or sample_sphere_uniform vex function?

 

[bunker]

this is how you use it:

 

// random vectors inside a sphere 

v@v= sample_sphere_uniform(rand(@P));

 

// random vectors inside a cube 

v@v= rand(@P) * vector(2) - 1;

 

// random vectors inside a sphere, with all vectors normalized

v@v = normalize(rand(@P)*vector(2)-1);

 

random_vectors.hip

 

also have a look at "sample_direction_cone" it does the same but inside a cone, very handy.
