Detailed Description

This is the abstract base class for standard positional data. Positional data is not exactly the same as a transform in that it does not permit scales, and the rotation is always applied before the translation.

Examples:

SIM/SIM_SolverSNOW.C.

Member Function Documentation

void SIM_Position::getInverseTransform

(

UT_DMatrix4 &

xform

)

const

Gets the inverse transform matrix from our position and rotation. This function just calls getInverseTransformSubclass().

Examples:

SIM/SIM_SolverSNOW.C.

virtual void SIM_Position::getInverseTransformSubclass

(

UT_DMatrix4 &

xform

)

const [protected, virtual]

This implementation calls getTransform and inverts it.

Reimplemented in SIM_PositionSimple.

void SIM_Position::getOrientation

(

UT_Quaternion &

q

)

const

Gets a matrix representing the rotation component of the position. This function just calls getRotationMatrixSubclass().

virtual void SIM_Position::getOrientationSubclass

(

UT_Quaternion &

q

)

const [protected, virtual]

This implementation calls getTransform and extracts the rotations.

Reimplemented in SIM_PositionSimple.

void SIM_Position::getPivot

(

UT_Vector3 &

p

)

const

Gets a vector representing the pivot component of the position. This function just calls getPivotSubclass().

virtual void SIM_Position::getPivotSubclass

(

UT_Vector3 &

p

)

const [protected, virtual]

This implementation returns (0, 0, 0) as the pivot.

Reimplemented in SIM_PositionSimple.

void SIM_Position::getPosition

(

UT_Vector3 &

t

)

const

Gets a vector representing the translation component of the position. This function just calls getPositionSubclass().

virtual void SIM_Position::getPositionSubclass

(

UT_Vector3 &

t

)

const [protected, virtual]

This implementation calls getTransform and extracts the translates.

Reimplemented in SIM_PositionSimple.

void SIM_Position::getTransform

(

UT_DMatrix4 &

xform

)

const

Gets a transform matrix from our position and rotation data. This function just calls getTransformSubclass().

virtual void SIM_Position::getTransformSubclass

(

UT_DMatrix4 &

xform

)

const [protected, virtual]

This implementation returns the identity matrix.

Reimplemented in SIM_PositionComposite, and SIM_PositionSimple.

UT_Vector3 SIM_Position::selfToWorld

(

const UT_Vector3 &

p

)

const

Transforms a point into worldspace from object space. This function just calls selfToWorldSubclass().

virtual UT_Vector3 SIM_Position::selfToWorldSubclass

(

const UT_Vector3 &

p

)

const [protected, virtual]

This implementation calls getTransform and does the multiply.
