In the dot function, it sums up the multiplication of two numbers. But if the two resulting numbers are Infinity and -Infinity, it results in NaN value for d variable.

Then, it causes hyperplaneFromPoints function to return a vector with NaN values. Then, in the getOptimalStart function, it pushes undefined via planePts.push(points[p]); since the p still equals to -1.

Finally, it causes an error: tympanum.module.js:161 Uncaught TypeError: Cannot read properties of undefined (reading '0')

        for (var j = 0; j < dim; ++j)
            v[j] = v0[j] - pt[j];

This is a part of the code in Miniverse.

function rebuildDelaunay() {
  probePositions = [];

  // Assure some size vertically
  const min = vec3.fromValues(Infinity, -30, Infinity);
  const max = vec3.fromValues(-Infinity, 30, -Infinity);

  irradianceProbes.forEach((probe, i) => {
    vec3.min(min, min, probe.position);
    vec3.max(max, max, probe.position);
    probePositions[i] = probe.position;
  });

Not sure what the underlying cause because I don't know understand the implementation details. It might be a bug in the software or a misusage. It'd be great @DerSchmale if you could have a look.
