Member Function Documentation

makeEditorInfo()

static PropertyTypeEditorInfoSharedPtr kanzi::TrajectoryLayoutConcept::makeEditorInfo ( )

static

getItemOffset()

static float kanzi::TrajectoryLayoutConcept::getItemOffset ( const Node & item )

static

Gets the offset of an item in a Trajectory Layout node.

Parameters

item	A node that is an item in a Trajectory Layout node.

Returns

The last offset calculated for the item by the Trajectory Layout.

getOverrideOffset()

static optional< float > kanzi::TrajectoryLayoutConcept::getOverrideOffset ( const Node & item )

static

Gets the fixed offset of an item on the trajectory.

Parameters

item	A node that is an item in a Trajectory Layout node.

Returns

The value of the OverrideOffsetProperty in the item, or if the property is not set, an empty optional.

setOverrideOffset()

static void kanzi::TrajectoryLayoutConcept::setOverrideOffset ( Node & item, float staticOffset )

static

Sets the fixed offset of an item on the trajectory.

Parameters

item	A node that is an item in a Trajectory Layout node.
staticOffset	The fixed offset on the trajectory, which the Trajectory Layout uses to position the item.

Examples

To manually position items in a Trajectory Layout node:

        // Position an item in the middle of the trajectory.
        TrajectoryLayout3D::setOverrideOffset(*item2, 0.5f);
 
        // Set the distance between the items to one third of the length of the trajectory.
        trajectoryLayout->setOverrideDistance(0.3f);

Member Data Documentation

TrajectoryProperty

PropertyType<ResourceSharedPtr> kanzi::TrajectoryLayoutConcept::TrajectoryProperty

static

Defines the Trajectory resource used by a Trajectory Layout node.

The default value is ResourceSharedPtr().

TrajectoryLayoutConceptImpl::setTrajectory(), TrajectoryLayoutConceptImpl::getTrajectory()

ItemAreaBeginProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::ItemAreaBeginProperty

static

Defines the starting point of the trajectory segment in which the layout items are considered fully visible.

The value is in [0, 1] range where 0 is the beginning and 1 is the end of the trajectory. See Node::VisibleAmountInParentProperty. The default value is 0.0f.

TrajectoryLayoutConceptImpl::setItemAreaBegin(), TrajectoryLayoutConceptImpl::getItemAreaBegin()

ItemAreaEndProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::ItemAreaEndProperty

static

Defines the ending point of the trajectory segment in which the layout items are considered fully visible.

The value is in [0, 1] range where 0 is the beginning and 1 is the end of the trajectory. See Node::VisibleAmountInParentProperty. The default value is 1.0f.

TrajectoryLayoutConceptImpl::setItemAreaEnd(), TrajectoryLayoutConceptImpl::getItemAreaEnd()

OverrideDistanceProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::OverrideDistanceProperty

static

Defines the fixed distance between items in the trajectory layout.

If not set, the trajectory layout calculates the distance and provides equal spacing between the items. The default value is 1.0f.

TrajectoryLayoutConceptImpl::setOverrideDistance(), TrajectoryLayoutConceptImpl::getOverrideDistance()

StartOffsetProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::StartOffsetProperty

static

Defines the starting offset on the trajectory from where the items are laid out.

The value is in [0, 1] range, where 0 is the beginning and 1 is the end of the trajectory. The default value is 0.0f.

See also

TrajectoryLayoutConceptImpl::setStartOffset(), TrajectoryLayoutConceptImpl::getStartOffset()

AlignToTangentProperty

PropertyType<bool> kanzi::TrajectoryLayoutConcept::AlignToTangentProperty

static

Sets whether the items in the trajectory layout are aligned to the tangent of the trajectory.

The default value is false.

See also

TrajectoryLayoutConceptImpl::setAlignToTangent(), TrajectoryLayoutConceptImpl::isAlignToTangent()

CalculatedOffsetProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::CalculatedOffsetProperty

static

Defines the value where the layout stores the current calculated offset along the trajectory calculated for an item.

The value is in [0, 1] range, where 0 is the beginning and 1 is the end of the trajectory. The default value is 0.0f.

See also

TrajectoryLayoutConceptImpl::getCalculatedOffset()

OverrideOffsetProperty

PropertyType<float> kanzi::TrajectoryLayoutConcept::OverrideOffsetProperty

static

Defines the fixed offset on the trajectory, which the trajectory layout uses to position an item.

If not set, the trajectory layout calculates the offset automatically. The value is in [0, 1] range, where 0 is the beginning and 1 is the end of the trajectory. The default value is 0.0f.

See also

setOverrideOffset(), getOverrideOffset()

StretchProperty

PropertyType<bool> kanzi::TrajectoryLayoutConcept::StretchProperty

static

If true, scale the trajectory to match layout size.

The default value is false.
