Helper functions to get properties of a scaling vector. More...

Functions
bool	IsNotScaled (Vec3Arg inScale)
	Test if a scale is identity.
bool	IsUniformScale (Vec3Arg inScale)
	Test if a scale is uniform.
bool	IsUniformScaleXZ (Vec3Arg inScale)
	Test if a scale is uniform in XZ.
float	ScaleConvexRadius (float inConvexRadius, Vec3Arg inScale)
	Scale the convex radius of an object.
bool	IsInsideOut (Vec3Arg inScale)
	Test if a scale flips an object inside out (which requires flipping all normals and polygon windings)
bool	IsZeroScale (Vec3Arg inScale)
	Test if any of the components of the scale have a value below cMinScale.
Vec3	MakeNonZeroScale (Vec3Arg inScale)
	Ensure that the scale for each component is at least cMinScale.
Vec3	MakeUniformScale (Vec3Arg inScale)
	Get the average scale if inScale, used to make the scale uniform when a shape doesn't support non-uniform scale.
Vec3	MakeUniformScaleXZ (Vec3Arg inScale)
	Average the scale in XZ, used to make the scale uniform when a shape doesn't support non-uniform scale in the XZ plane.
bool	CanScaleBeRotated (QuatArg inRotation, Vec3Arg inScale)
Vec3	RotateScale (QuatArg inRotation, Vec3Arg inScale)

Detailed Description

Helper functions to get properties of a scaling vector.

Function Documentation

CanScaleBeRotated()

bool ScaleHelpers::CanScaleBeRotated ( QuatArg inRotation, Vec3Arg inScale )

inline

Checks in scale can be rotated to child shape

Parameters

inRotation	Rotation of child shape
inScale	Scale in local space of parent shape

Returns

True if the scale is valid (no shearing introduced)

IsInsideOut()

bool ScaleHelpers::IsInsideOut ( Vec3Arg inScale )

inline

Test if a scale flips an object inside out (which requires flipping all normals and polygon windings)

IsNotScaled()

bool ScaleHelpers::IsNotScaled ( Vec3Arg inScale )

inline

Test if a scale is identity.

IsUniformScale()

bool ScaleHelpers::IsUniformScale ( Vec3Arg inScale )

inline

Test if a scale is uniform.

IsUniformScaleXZ()

bool ScaleHelpers::IsUniformScaleXZ ( Vec3Arg inScale )

inline

Test if a scale is uniform in XZ.

IsZeroScale()

bool ScaleHelpers::IsZeroScale ( Vec3Arg inScale )

inline

Test if any of the components of the scale have a value below cMinScale.

MakeNonZeroScale()

Vec3 ScaleHelpers::MakeNonZeroScale ( Vec3Arg inScale )

inline

Ensure that the scale for each component is at least cMinScale.

MakeUniformScale()

Vec3 ScaleHelpers::MakeUniformScale ( Vec3Arg inScale )

inline

Get the average scale if inScale, used to make the scale uniform when a shape doesn't support non-uniform scale.

MakeUniformScaleXZ()

Vec3 ScaleHelpers::MakeUniformScaleXZ ( Vec3Arg inScale )

inline

Average the scale in XZ, used to make the scale uniform when a shape doesn't support non-uniform scale in the XZ plane.

RotateScale()

Vec3 ScaleHelpers::RotateScale ( QuatArg inRotation, Vec3Arg inScale )

inline

Adjust scale for rotated child shape

Parameters

inRotation	Rotation of child shape
inScale	Scale in local space of parent shape

Returns

Rotated scale

ScaleConvexRadius()

float ScaleHelpers::ScaleConvexRadius ( float inConvexRadius, Vec3Arg inScale )

inline

Scale the convex radius of an object.
