Public Functions Documentation

function Transform

cpp

explicit Transform(
    const TransformOperation & transformType
)

function createDefaults

cpp

void createDefaults()

Prepare storage for second level parameters (std::map with values)

function disableSynergies

cpp

inline void disableSynergies()

function enableSynergies

cpp

inline void enableSynergies()

function free

cpp

inline void free()

function getCurrentIndex

cpp

inline int getCurrentIndex() const

function getCurrentSequence

cpp

Ptr< Node > getCurrentSequence()

function getDefaultTypes

cpp

TransformOperation::ValueMap getDefaultTypes() const

Return: A map of valueName and value pairs.

function getDefaultValue

cpp

const Data & getDefaultValue(
    const std::string & name
) const

Get the value which the transform can hold (current value stored in the transformation).

Todo: rename to getCurrentValue?

Precondition: Default value with name exists.

It is not the initial value!

function getDefaultValues

cpp

DefaultValues & getDefaultValues()

function getValueState

cpp

EValueState getValueState(
    glm::ivec2 coords
) const

function hasMenuSynergies

cpp

inline bool hasMenuSynergies() const

function hasSavedValue

cpp

bool hasSavedValue() const

function hasSynergies

cpp

inline bool hasSynergies() const

function initDefaults

cpp

inline virtual void initDefaults()

Init the (non-zero) second level parameters (from LOD::SetValues) via their initDefaults and update the internal transformation matrix).

It is overriden in all transforms with their default values. This version is for nodes without the default value (now only the Free node)

It resets the matrix to identity.
this is done in free->resetMatrixFromDefaults()

function isInSequence

cpp

inline bool isInSequence() const

function isLocked

cpp

bool isLocked() const

function isValid

cpp

virtual bool isValid() const =0

Checks the validity of the stored Transform matrix (used by GUI to show the corrupted flag).

Return: true if the stored matrix represents a correct transform

Todo: isValid checks matrix AND parameters from the SetValues LOD (Default values)

function lock

cpp

void lock()

function notifySequence

cpp

void notifySequence()

function nullSequence

cpp

inline void nullSequence()

Todo: MH these should not be public.

function properties

cpp

TransformOperation * properties() const

function reloadValue

cpp

void reloadValue()

Restore saved values if they exist.

function resetMatrixFromDefaults

cpp

virtual void resetMatrixFromDefaults() =0

Reset the transform matrix visible in LOD::Full (internalValue) to match the defaultValues (from LOD::SetValues).

Todo: For synergies, it has to be resolved. Most probably, it should leave the synergies unchanged.

for Scale When setting X value in non-uniform scale -> this switch to uniform scale (due to enable synergies)

Specialized functions are created for each Transform type. For transforms with no default values (now only Free), resets the matrix directly.

The opposite setup - from matrix to Defaults - is done in the setValue() functions. It should also lock the matrix.

function saveValue

cpp

void saveValue()

Save current values of the transformation for future reloading.

function setDefaultValue

cpp

template <typename T >
inline SetValueResult setDefaultValue(
    const std::string & name,
    T && val
)

Setting of one second level parameter defining the transformation (in LOD::SetValues).

Parameters:

name Name of the parameter (such as Center)
val New value

Template Parameters:

T Type of the stored value val

You can find transform names, types, and their default values, in the file Core/Nodes/Operation.h. The initial values are hard-wired in initDefaults() of TransformImpl<ETransformType...> in TransformImpl.h

function setDefaultValueNoUpdate

cpp

template <typename T >
inline void setDefaultValueNoUpdate(
    const std::string & name,
    T && val
)

function setDefaultValues

cpp

inline void setDefaultValues(
    const DefaultValues & values
)

function setSequence

cpp

inline void setSequence(
    Node * s,
    int index
)

function setValue

cpp

virtual SetValueResult setValue(
    const glm::mat4 & mat
) override

Lock non-editable values.

Reimplements: Core::Node::setValue

Reimplemented by: Core::TransformImpl< ETransformType::AxisAngle >::setValue, Core::TransformImpl< ETransformType::Quat >::setValue

And enable synergies, if exist, i.e., hasSynergies() == true

function setValue

cpp

virtual SetValueResult setValue(
    float val,
    glm::ivec2 coords
) override

Parameters:

val new value
coords in the column major order: coords.x is the column index and coords.y is the row index.

Return:

Reimplements: Core::Node::setValue

function unlock

cpp

void unlock()

Protected Functions Documentation

function canSetValue

cpp

bool canSetValue(
    const ValueMask & mask,
    glm::ivec2 coords,
    float value
)

function getDefaultValueMut

cpp

Data & getDefaultValueMut(
    const std::string & name
)

Precondition: Default value with name exists.

function setDefaultValueWithSynergies

cpp

virtual void setDefaultValueWithSynergies(
    const std::string & name,
    Core::Data && val
)

Function for setting values in the Set Defaults LOD.

Parameters:

name changed data field
val newValue as Core::Data(newValue)!!! (as we cannot have virtual template functions)

Reimplemented by: Core::TransformImpl< ETransformType::Quat >::setDefaultValueWithSynergies, Core::TransformImpl< ETransformType::Ortho >::setDefaultValueWithSynergies, Core::TransformImpl< ETransformType::Frustum >::setDefaultValueWithSynergies

Performs default data correction based on synergies Do not use - use setDefaultValue() instead!!!

Protected Attributes Documentation

variable m_defaultValues

cpp

DefaultValues m_defaultValues;

variable m_hasMenuSynergies

cpp

bool m_hasMenuSynergies = false;

True for transformations, that support synergies, such as scale, eulerAngleXYZ, ortho, frustum, and quaternion ONLY.

Synergies variants | Transformation | hasMenuSynergies | show in Full LOD | show in SetValues | synergies force | | ------------—|---------------—|---------------—|----------------—|--------------—| | Free | no | no | no | | | Translate | no | no | no | | | AxisAngle rot | no | no | no | | | LookAt | no | no | no | | | Perspective | no | no | no | | | Ortho | yes | no | yes | | | Frustum | yes | no | yes | | | Quat | yes | no | yes | unitQuaternion | | Scale | yes | yes | yes | uniform scale | | EulerX,Y,Z | yes | yes | no | cos and sins |

variable m_hasSynergies

cpp

bool m_hasSynergies = false;

applicable for: uniform scale, eulerAngleXYZ, ortho, frustum, and quat and quaternion.

All other undefined (false)

variable m_isLocked

cpp

bool m_isLocked = true;

Edit of the matrix is limited to editable values - defined in Operations.h g_transforms.
