Hi, I’m Kartik.

I’m mostly just a kid with internet, building whatever seems fun enough to keep me up at night.

I build for the joy of making software and watching real people use it.

I’m an engineering student, class of 2027.

p (t) = \frac{\sin ((1 - t) δ)}{\sin (δ)} p_{0} + \frac{\sin (t δ)}{\sin (δ)} p_{1}

t 0.42

AerisSpherical linear interpolation

C (t) = \frac{(τ_{2} - t) B_{1} + (t - τ_{1}) B_{2}}{τ_{2} - τ_{1}}

P₃ latitude 0.95°

AerisCentripetal Catmull–Rom spline

p (s, k) = (1 - k) s + k \sin (1.5 s_{yx} + 2 \cos s)

Warp 0.38

edbn/uiSinusoidal coordinate warp

P_{N} = 1 - \prod_{i = 1}^{N} [1 - Φ (\frac{c_{i} - r}{max (σ_{eff}, 1)})]

Rank 5,100P₅ = 97.3%
