Classes
class	cmlabs::Color
	24-bit RGB color with mixing, inversion, distance and palette-generation helpers. More...
class	cmlabs::Size
	2D/3D extent (width, height, optional depth) stored as doubles. More...
class	cmlabs::Point
	Integer 3D point with an optional attached Size; interoperates with PointFloat and vectors. More...
class	cmlabs::PointFloat
	Floating-point 3D point with an optional attached Size; float counterpart of Point. More...
class	cmlabs::Line
	Line segment between two PointFloat endpoints with a drawing width. More...
class	cmlabs::PolyLine
	Ordered collection of Line segments (not necessarily connected). More...
class	cmlabs::Box
	Axis-aligned rectangle defined by an upper-left corner and a Size, with overlap/containment math. More...
class	cmlabs::Vector2D
	2D vector with the usual linear algebra: dot product, determinant, projection, rotation, angles. More...
class	cmlabs::Vector3D
	3D vector with dot/cross products, projection and angle math. More...
class	cmlabs::RandomPathGenerator
	Generates a smoothly wandering 2D path: each call to generateNextPoint() advances the last point along a direction vector perturbed by a random variation, useful for simulated motion in tests/demos. More...

Functions
bool	cmlabs::MathClasses_UnitTest ()
	Unit test for the MathClasses module (geometry / vectors / boxes).

Variables
const std::map< std::string, std::array< uint8, 3 > >	cmlabs::ColorMap
	Lookup table mapping ~200 CSS/X11 color names (with and without spaces) to 8-bit RGB triplets; used by Color(const char*).

Detailed Description

Geometry and 2D/3D math value classes: Color, Size, Point, PointFloat, Line, PolyLine, Box, Vector2D, Vector3D and a random path generator.

These lightweight value types are used across CMSDK/Psyclone for image regions, tracking, visualization and spatial reasoning. All members are public by design; the classes are simple aggregates with convenience math. Angles are radians unless noted; coordinate system is screen-style with the origin at the upper-left and y growing downward (relevant for Box).
