You're looking at an image featuring a yellowish paper with handwritten text and diagrams. At the top, there's a sketched square divided by a vertical line into two rectangles, with a small "3" written above it. Below the square is the main body of handwritten text describing the sketches beneath it. One sketch appears to represent a cross-section of a gemstone or similar object, showing faceting, with a couple of arrows indicating direction. Alongside the gemstone, there's a smaller sketch that seems to be illustrating a perspective view of the same shape with lines radiating from a center point toward the corners. The handwriting is cursive and somewhat difficult to read due to its hurried and uneven style, but it seems to be explaining the concepts of depth and horizontal/vertical directions as they relate to the diagrams. Notably, the text includes terms like "depth direction," "horizontal and vertical direction," and "identical point positions."

The image appears to be a hand-drawn diagram with annotations. The diagram depicts a cross-section or schematic representation of some kind of object or system. The annotations describe various features and relationships, including a "depth direction between b&b" and "application to factor in C-S". The overall subject and purpose of the diagram are not entirely clear from the information provided in the image alone. However, the image seems to be a technical or scientific illustration with accompanying notes that provide additional context and details about the depicted content.
