Parameterization quantity

Parameterization Quantity Options¶

These options and behaviors are available for all types of parameterization quantities on any structure.

Several styles are available for how a parameterization is displayed.

The enum class ParamVizStyle has options for how parameterizations are visualized:

CHECKER: a two-color checker pattern
GRID: a grid with thin lines
LOCAL_CHECK: a checkboard over a radial colormap, centered around (0,0)
LOCAL_RAD: distance stripes over a radial colormap, centered around (0,0)
CHECKER_ISLANDS: a checkerboard where islands are colored according to the island labels integer, which must be given explicitly (meshes only)

The function SurfaceParameterizationQuantity::setStyle(ParamVizStyle newStyle) can be used to programmatically change the style.

The enum class ParamCoordsType has options that control how parameter coordinates are interpreted:

UNIT: UV coords are assumed to lie on the [0,1] interval
WORLD: UV coords are assumed to be scaled like the world-space positions of the mesh

These enums can be passed as an optional third argument when a parameterization is registered.

Parameter	Meaning	Getter	Setter	Persistent?
enabled	is the quantity enabled?	`bool isEnabled()`	`setEnabled(bool newVal)`	yes
style	the visualization style (see above)	`ParamVizStyle getStyle`	`setStyle(ParamVizStyle style)`	yes
checker colors	two colors to use for checkerboards	`std::pair<glm::vec3,glm::vec3>getCheckerColors()`	`setCheckerColors(std::pair<glm::vec3, glm::vec3> colors)`	yes
grid colors	two colors to use for line and background of grid	`std::pair<glm::vec3,glm::vec3>getGridColors()`	`setGridColors(std::pair<glm::vec3, glm::vec3> colors)`	yes
checker size	the width of checkers / stripes, always used as a relative value, unless the coord tpe is `UNIT`	`double getCheckerSize()`	`setCheckerSize(double val)`	yes
color map	the color map to use for radial displays	`std::string getColorMap()`	`setColorMap(std::string newMap)`	yes
