Instance Method

initWithName:semantic:float3:

Initializes a material property with a 3-component vector value.

Declaration

- (instancetype)initWithName:(NSString *)name semantic:(MDLMaterialSemantic)semantic float3:(vector_float3)value;

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.

value

The 3-component floating-point vector value for the material property.

Return Value

A new material property object whose type property is MDLMaterialPropertyTypeFloat3.

Discussion

A 3-component vector can also be used to store RGB color values. In this case, color components should be interpreted using the Rec. 709 color space standard.
