Intelligent spatial geometry gives a 'breathing space' of open volumes.

The spatial geometry of the universe is conformally flat.

The R value is also a function of the spatial geometry between the observer, light source, and reflector.

Gaudí evolved from plane to spatial geometry, to ruled geometry.

Dimensions is a French project that makes educational movies about mathematics, focusing on spatial geometry.

The homogeneous and isotropic universe allows for a spatial geometry with a constant curvature.

If the spatial geometry is spherical, the topology is compact.

Painter and engraver, de Margerie starts with a spatial geometry using long lines or curves.

This feat also demonstrates his intuitive sense of spatial geometry between objects.
