The plural form or the field/practice of creating or working with anaglyphs and anaglyphic images.
From anaglyph or anaglyphic plus the plural -s or the field suffix -ics, treating it as a body of knowledge or practice.
Just as 'graphics' is the field of making visual images, 'anaglyphics' would be the specific practice of making 3D images through color-separation techniques—though this term is rarely used today.
