I am creating a tool that needs to draw meshes and gizmos in the scene view. Right now, I have it drawing both from a temp object I create in the scene, but I would rather not create that object. Is there some way to draw meshes and gizmos directly from an EditorWindow?
After more searching, I found this question Drawing to the scene from an EditorWindow - Questions & Answers - Unity Discussions and now have it drawing meshes and handles using SceneView.onSceneGUIDelegate
