Detailed Description

This is the simplest implementation 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.

Member Function Documentation

virtual void SIM_PositionSimple::getInverseTransformSubclass

(

UT_DMatrix4 &

xform

)

const [protected, virtual]

Gets the inverse transform matrix from our position and rotation. Because we build our transform matrices just in time, this is faster than getTransform() & invert().

Reimplemented from SIM_Position.

virtual void SIM_PositionSimple::getOrientationSubclass

(

UT_Quaternion &

q

)

const [protected, virtual]

Gets a rotation matrix from our position data.

Reimplemented from SIM_Position.

virtual void SIM_PositionSimple::getPivotSubclass

(

UT_Vector3 &

p

)

const [protected, virtual]

Gets pivot info from our position data.

Reimplemented from SIM_Position.

virtual void SIM_PositionSimple::getPositionSubclass

(

UT_Vector3 &

t

)

const [protected, virtual]

Gets a translation vector from our position data.

Reimplemented from SIM_Position.

SIM_PositionSimple::GETSET_DATA_FUNCS_Q	(	SIM_NAME_ORIENTATION	,
		Orientation
	)

Control the orientation attribute of the position.

SIM_PositionSimple::GETSET_DATA_FUNCS_V3	(	SIM_NAME_PIVOT	,
		Pivot
	)

Control the pivot point which the orientation is applied to.

SIM_PositionSimple::GETSET_DATA_FUNCS_V3	(	SIM_NAME_POSITION	,
		Position
	)

Control the translation attribute of the position.

TODO: These accessors are shadowing the SIM_Position versions. This is a bad thing as getPivot() will not invoke getPivotSubclass and anyone trying to chase the call graph will see an apparent infinite loop. We need to rename these to RawPosition, I think.

virtual void SIM_PositionSimple::getTransformSubclass

(

UT_DMatrix4 &

xform

)

const [protected, virtual]

Gets a transform matrix from our position and rotation data.

Reimplemented from SIM_Position.

virtual void SIM_PositionSimple::interpolateSubclass	(	const SIM_Data *	source1,
		const SIM_Data *	source2,
		fpreal	interp
	)			[protected, virtual]

Interpolation of positions can't be done in a componentwise fashion. If pivot is changing over time it is important that we adjust the rotation/translation to account for it.

Reimplemented from SIM_Data.

virtual void SIM_PositionSimple::optionChangedSubclass

(

const char *

name

)

[protected, virtual]

Override this function so that we can understand an option called rotation. Although this attribute isn't supported directly, it can be reinterpreted into the orientation option.

Reimplemented from SIM_OptionsUser.

Reimplemented in RBD_State.

virtual UT_Vector3 SIM_PositionSimple::selfToWorldSubclass

(

const UT_Vector3 &

p

)

const [protected, virtual]

Transforms a point into worldspace from object space. This is the same as multiplying by getTransform()

Reimplemented from SIM_Position.

virtual UT_Vector3 SIM_PositionSimple::selfToWorldVectorSubclass

(

const UT_Vector3 &

p

)

const [protected, virtual]

Transforms a vector into worldspace from object space. This is the same as multiplying by getTransform()

Reimplemented from SIM_Position.

virtual UT_Vector3 SIM_PositionSimple::worldToSelfSubclass

(

const UT_Vector3 &

p

)

const [protected, virtual]

Transforms a point into object space from world space. This is the same as multiplying by getInverseTransform()

Reimplemented from SIM_Position.

virtual UT_Vector3 SIM_PositionSimple::worldToSelfVectorSubclass

(

const UT_Vector3 &

p

)

const [protected, virtual]

Transforms a vector into object space from world space. This is the same as multiplying by getInverseTransform()

Reimplemented from SIM_Position.
