Troubleshooting Floating-Point Issues on Line 30 in Three.js Procedural Heart Animation

I notice you're working on animating a procedurally generated heart in Three.js and experiencing issues with your implementation. However, you haven't provided your actual code that's causing problems, just placeholder code. Without seeing your specific implementation, it's difficult to diagnose the exact issue.

If you're dealing with floating-point precision issues related to cube roots in your heart animation, I can suggest a few approaches:

Potential Solutions for Floating-Point Issues

1. Use MathUtils: Three.js provides a MathUtils class that contains various utility functions which might help with precision issues:

JAVASCRIPTCopied
import { MathUtils } from 'three';

// Instead of direct Math operations
const result = MathUtils.clamp(value, min, max);

2. For Animation Interpolation: Consider using Three.js interpolation classes for smooth transitions:

JAVASCRIPTCopied
import { LinearInterpolant } from 'three';

// Create an interpolant for smooth animation
const interpolant = new LinearInterpolant(
  times, // Array of time keyframes
  values, // Array of values to interpolate between
  valuesSize, // Size of each value
  result // Optional result array
);

// Get interpolated value at time t
const value = interpolant.evaluate(t);

3. For Quaternion-based Rotations: If your heart animation involves rotations, use QuaternionLinearInterpolant for smoother results:

JAVASCRIPTCopied
import { QuaternionLinearInterpolant } from 'three';

// For rotation interpolation
const rotationInterpolant = new QuaternionLinearInterpolant(
  times,
  rotationValues,
  4, // Quaternions have 4 components
  result
);

If you could share your actual implementation code (especially the problematic line 30 you mentioned), I could provide more specific guidance tailored to your heart animation issue.
