+## A fuzzer that generates random Vector3 values within a specified box range.[br]
+##
+## This is particularly useful for testing 3D physics, spatial
+## positioning, camera systems, particle effects, or any code that processes 3D vectors.[br]
+##
+## The fuzzer generates vectors where each component (x, y, z) is independently
+## randomized within its respective range, creating a uniform distribution over the
+## 3D box volume.[br]
+##
+## [b]Usage example:[/b]
+## [codeblock]
+## # Test 3D object placement within world bounds
+## func test_spawn_position(fuzzer := Vector3Fuzzer.new(Vector3(-100, 0, -100), Vector3(100, 50, 100)), _fuzzer_iterations := 300):
+##     var position := fuzzer.next_value()
+##     var object = spawn_object(position)
