Continuous function
A function whose output changes arbitrarily little when its input changes arbitrarily little.
Geometry for Programmers
Continuity is the property of a function having no excluded domain points within its intended domain and no abrupt changes in value.
- How it is used
- Uses continuity to distinguish usable function behavior and model curves and surfaces in geometry.
- How deep it goes
- Defines continuity intuitively, contrasts domain gaps and jumps, and extends treatment through C1, C2, and C3 spline continuity without formal definition.
- Examples
- Uses sine, tangent, floor, polylines, and degree-varied NURBS to illustrate continuity and smoothness.
- What you can do after
- Evaluate whether functions and spline curves contain gaps, jumps, or stated levels of continuity.

Continuity is the property that sufficiently small changes in a function's input produce sufficiently small changes in its output.
- How it is used
- Explains why variational autoencoders learn latent spaces that support smooth image variation and manipulation.
- How deep it goes
- Defines continuity intuitively and connects it to latent sampling, stopping short of formal mathematical conditions.
- Examples
- Uses random latent sampling around an encoded image and shows the encoder-to-decoder transformation.
- What you can do after
- Evaluate why nearby latent points should decode to similar images in a variational autoencoder.
