public class ShaderAttributeArray extends ShaderAttributeObject
attrName is explicitly set to the specified
value during rendering. attrName must be
the name of a valid uniform attribute in the shader in which it is
used. Otherwise, the attribute name will be ignored and a runtime
error may be generated. The value must be an array
of one of the allowed classes. The allowed classes are:
Integer[], Float[],
Tuple{2,3,4}{i,f}[], Matrix{3,4}f[]. A
ClassCastException will be thrown if a specified value
object is not one of the allowed types. Further, the type and length of the
value is immutable once a ShaderAttributeArray is constructed.
Subsequent setValue operations must be called with an array of the
same type and length as the one that was used to construct the
ShaderAttributeArray. Finally, the type of the value
object must match the type of the corresponding
attrName variable in the shader in which it is
used. Otherwise, the shader will not be able to use the attribute
and a runtime error may be generated.ShaderAttributeSet,
