Worksheet 6 — Part 3 · Textured Earth with Orbit Controls

We sample the globe using trilinear filtering (linear minification and mipmap filtering plus linear magnification). The trilinear choice balances sharp coastlines when the planet fills the view while fading aliasing in the alpine regions when the camera spins away—mipmaps eliminate the highest-frequency details before they shimmer, and the linear blend between mip levels avoids noticeable popping.
