The TD layer simulator

Transmission Distance (TD) is the one number that decides how a HueForge print looks β€” but it's invisible on the spool. Drag the sliders below: watch the same filament read as a pale wash at one layer and its full colour a few layers later. That's TD, made visible.

4.0 mm Β· translucent

Low TD blocks the layer below in one pass (opaque); high TD lets it show through, so colour builds slowly.

Front-lit: the base shows through by the transmittance below; a black base creates shadows.

Tracked filaments nearest to TD 4.0 β€” good for soft blends & backlit glow Β· we don't track much filament this translucent yet, so these are the closest, not exact:

Simulation using base-10 Beer-Lambert (T = 10βˆ’d/TD) composited in linear light β€” it predicts the trend, not an exact swatch (real prints scatter light and read a little lighter/softer).
