Initializer

init(name:semantic:string:)

Initializes a material property with a string value.

Declaration

convenience init(name: String, semantic: MDLMaterialSemantic, string: String?)

Parameters

name

A descriptive name for the material property. For details, see the name property.

semantic

The semantic meaning for the material property’s value. For details, see the semantic property.

string

The string value for the material.

Return Value

A new material property object whose type property is MDLMaterialPropertyType.string.

Discussion

The meaning of a string value depends on the renderer (or other software component) processing the material. For example, a string value might be treated as the name of a texture image to be loaded from a default path.
