Values and type information for per-instance geometry attributes.
alias GeometryInstanceAttribute
- The options object takes the following properties
- {ComponentDatatype} [options.componentDatatype] The datatype of each component in the attribute, e.g., individual elements in values.
- {Number} [options.componentsPerAttribute] A number between 1 and 4 that defines the number of components in an attributes.
- {Boolean} [options.normalize=false] 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.
- {Number[]} [options.value] The value for the attribute.
exception {DeveloperError} options.componentsPerAttribute must be between 1 and 4.
