PolygonalTechniqueParams

Declares a a geometry as a polygon.

Index

Fill color in hexadecimal or CSS-style notation, for example: "#e4e9ec", "#fff", "rgb(255, 0, 0)", or "hsl(35, 11%, 88%)".

depthTest: DynamicProperty<boolean>

Sets the polygon outline color.

lineFadeFar: DynamicProperty<number>

Distance to the camera (0.0 = nearPlane, 1.0 = farPlane) at which the object edges become transparent. A value of <= 0.0 disables fading.

lineFadeNear: DynamicProperty<number>

Distance to the camera (0.0 = nearPlane, 1.0 = farPlane) at which the object edges start fading out.

opacity: DynamicProperty<number>

For transparent lines, set a value between 0.0 for fully transparent, to 1.0 for fully opaque.

polygonOffset: undefined | false | true

Whether to use polygon offset. Default is false.

remarks

This corresponds to the GL_POLYGON_OFFSET_FILL WebGL feature.

PolygonOffset is used to raise the geometry towards the geometry (for depth calculation only). Default is false.

To activate polygonOffset these values have to be set to pull the line "forwards":

transparent: true

polygonOffset: true

polygonOffsetFactor : -1.0, (as an example, see link above)

polygonOffsetUnits: -1 (as an example, see link above)

polygonOffsetFactor: DynamicProperty<number>

Sets the polygon offset factor. Default is 0.

polygonOffsetUnits: DynamicProperty<number>

Sets the polygon offset units. Default is 0.

transparent: DynamicProperty<boolean>

Set to true if line should appear transparent. Rendering transparent lines may come with a slight performance impact.
