val componentDatatype: ComponentDatatype

The datatype of each component in the attribute, e.g., individual elements in ColorGeometryInstanceAttribute.value.

Link copied to clipboard
val componentsPerAttribute: Int

The number of components in the attributes, i.e., ColorGeometryInstanceAttribute.value.

Link copied to clipboard
val normalize: Boolean

When true and componentDatatype is an integer format, indicate that the components should be mapped to the range 0, 1 (unsigned) or -1, 1 (signed) when they are accessed as floating-point for rendering.

var value: Uint8Array

The values for the attributes stored in a typed array.
