My goal for developing PoseBook 3D was to create a self controlled tool for artists to practice their construction and rotation of heads. Not only will it be a great tool to give you a better understanding of how forms move in space, but it will teach you how to draw the same head in multiple angles. Another great use of this app is for painters who wish to use it as lighting reference for shadows. Two of my greatest teachers in life were Andrew Loomis and George Bridgman.They taught me through their work the importance of rotating forms in space and this is why we have created the first app to offer a variety of character heads created by a variety of artists with different styles. PoseBook 3D gives you full rotation and lighting control and can be used on the go. This app will guide the artist in developing a better understanding of construction, tilts and perspective of the forms as long as you put it to continuous use. It is ideal for creating your own characters. For additional tutorials and videos, please visit https://www.youtube.com/silvertoons Enjoy, Silver
