Struct Vec3

Source

pub struct Vec3 { /* private fields */ }

Expand description

A structure capable of holding a vector with three dimensions: x, y, and z.

The contents of the Vec3 structure are private and should never be accessed directly.

GLib type: Inline allocated boxed type with stack copy semantics.
