Classes
class	ToyMaker::RangeMapperLinear
	A simple linear interpolation implementation between a fixed input and output range. More...

Namespaces
namespace	ToyMaker
	Namespace containing all class definitions and functions related to the ToyMaker engine.

Functions
glm::mat4	ToyMaker::buildModelMatrix (glm::vec4 position, glm::quat orientation, glm::vec3 scale=glm::vec3{1.f, 1.f, 1.f})
	Converts a position, orientation and scale into its model matrix equivalent.
float	ToyMaker::squareDistance (const glm::vec3 &vector)
	Returns the square of the length of a 3 component vector.
bool	ToyMaker::isFinite (float number)
	Tests whether a given number is finite.
bool	ToyMaker::isFinite (const glm::vec3 &vector)
	Tests whether a set of 3 numbers is finite.
bool	ToyMaker::isPositiveStrict (float number)
	Tests whether a number is strictly positive.
bool	ToyMaker::isPositiveStrict (const glm::vec3 &vector)
	Tests whether a set of 3 numbers is strictly positive.
bool	ToyMaker::isNumber (float number)
	Tests whether a float is really a number (as opposed to a special error representation).
bool	ToyMaker::isNumber (const glm::vec3 &vector)
	Tests whether a set of 3 numbers are really numbers (as opposed to special error representations).
bool	ToyMaker::isNonNegative (float number)
	Tests whether a number is non-negative.
bool	ToyMaker::isNonNegative (const glm::vec3 &vector)
	Tests whether a set of numbers is non-negative.
glm::quat	ToyMaker::getRotation (const glm::vec3 &from, const glm::vec3 &to)
	Returns the rotation between two vectors represented as a quaternion.
float	ToyMaker::getAngle (const glm::vec3 &from, const glm::vec3 &to, const glm::vec3 &axis)
	Gets angle between two vectors about an axis vector in the range [-Pi, Pi].
glm::vec3	ToyMaker::getOrthogonal (const glm::vec3 &from)
	Given some arbitrary non-zero vector, returns a normalized vector that is orthogonal to it.
std::pair< glm::vec3, glm::vec3 >	ToyMaker::getTangents (const glm::vec3 &vector)
	Returns a pair of normalized tangents to an input vector.
bool	ToyMaker::isSensible (const glm::mat3 &matrix)
	Determines whether a particular matrix is valid and finite.
glm::mat4	ToyMaker::getScaleMatrix (const glm::mat4 &fromTransform)
	Given a transform, returns scale matrix that was used to compose the transform.
glm::mat4	ToyMaker::getRotationMatrix (const glm::mat4 &fromTransform)
	Given a transform, returns rotation matrix that was used to compose the transform.
glm::mat4	ToyMaker::getTranslationMatrix (const glm::mat4 &fromTransform)
	Given a transform, returns translation matrix that was used to compose the transform.
