UNDERSTANDING, THROUGH EXPLORATION
Different animals.
A connected story.
From a cat’s compact frame to a giraffe’s long neck, mammals share a basic body plan. This atlas makes that idea tangible: rotate the model, peel back a layer, and follow a structure from the whole animal to a conceptual muscle-fibre view.
These procedural illustrations are for introductory exploration. They omit organs, many individual bones and muscles, and variation between breeds, ages and sexes. They are not veterinary reference models. Zoom changes your viewpoint; enable “Reveal layers as I zoom” to step through layers automatically, or use the depth control.
Reading & model information
Anatomy explanations draw on the Merck Veterinary Manual and OpenStax Biology: muscle contraction and locomotion. These sources inform the text; they do not validate the model geometry.
3D rendering: Three.js, MIT license. Model geometry: original procedural illustrations. The current collection covers twelve mammals; other animal families are not yet modelled.
