The SetData method in the RenderAttributes class is used to set a data attribute for rendering purposes. This method allows you to specify a key and a value, where the key is a StringToken and the value is a span of generic type T. This is useful for setting data that can be used in rendering operations, such as shader parameters or other rendering attributes.
To use the SetData method, you need to have an instance of the RenderAttributes class. You can then call the method with the appropriate parameters:
k: A reference to a StringToken that represents the key for the data attribute.value: A System.Span<T> that contains the data to be set.Ensure that the type T is compatible with the rendering system and the data you intend to set.
RenderAttributes renderAttributes = new RenderAttributes();
StringToken key = new StringToken("exampleKey");
Span<float> data = stackalloc float[] { 1.0f, 2.0f, 3.0f };
renderAttributes.SetData(ref key, data);
