A 3D framework designed to assist artists with sketching human heads. Based loosely on the Andrew Loomis method, this Blender setup uses a collection of curve objects parented to a central controller to easily pose the head using trackball rotation. The file includes internal guides for marking the corners of the brows and cheekbones. It features automated camera focal length adjustments tied to positioning, simulating various lens distortions like telephoto and fisheye while keeping the guide framed within the render border.
