It'll be convenience for hydra used by Node.js.

Usage

1. When you'd like to change the canvas axis to "y" perspective.

• osc().scale(glslAxis("y")).out();
• voronoi(20,1,5).scale(glslAxis("2y")).out();

2. It can be modulated using the difference between "solid" and "gradient" color changes.

• speed=1/4;
flash(1,2,1).diff(osc(30,1/8,300).diff(osc(30,1/8,300).rotate(Math.PI/2))).scale([1/4,1/2].smooth()).out();

3. You can also use functions that store trigonometric and inverse trigonometric functions to change the video.

• noise().rotate(()=>list(1,2)).out();

4. The options available within hydra's "ease" function can also be easily specified.

• gradient(1).hue([0,1].ease(easeInOut(5))).out();

5. Variables can be defined sequentially and the last variable among them can be used. (It can also be used outside of hydra.)

• osc().rotate(varDef("hydra",Math.atan,10)).out();

6. Two different functions can be entered, each increasing in a different step, and the results put into an array and modulated.

• shape(funcAry(4,5,6,0.05,0.1,Math.tan,Math.sin).smooth()).out();

7. It can generate an array from 0 to a specified number and output a random value.

• shape(randAry(100,0.1)).out();

8. It can generate an array from 0 to a specified number, repeatedly output a random value, and store it in the array again.

• shape(genAry(100,0.1,10).smooth()).out();

9. Four output videos can be looped and switched every specified number of seconds at specified speeds.

• setLoop(1/2,-1/4,-1/2,1/4,1000);
osc().out();
noise().out(o1);
gradient(1).out(o2);
voronoi().out(o3);

10. Others(form, pad, particle, rbga, hsb, rainbow and zebra)

• form(4,2,0,1,15,1/8,0).colorama(3).luma().hue(()=>Math.sin(time/10),()=>Math.cos(time/10),()=>Math.tan(time/10)).diff(gradient(1)).invert().scale(Math.PI).repeat().out();
• pad(10,o0,4,0,1,.99).diff(osc(1,2,300).diff(gradient(1)).scale(.1)).diff(rgba(o0,1,1,1,1)).diff(hsb(o0,1,1,1/4)).invert().out();
• gradient().blend(rainbow(3)).out();
• osc(1,2,300).diff(gradient(1)).scale(.1).diff(particle(o0,.99)).invert().out();
• s0.initCam();
solid().add(zebra(src(s0), 2, 4, Math.sin, 0.1)).out();

I appreciate all hydra users or developers on GitHub, FB, Twitter or Discord, etc...
