different types of beams and plaster recorded on the ceilings In the book "Vixen-03" by Clive Cussler there is a fragment about an entertainer who is recalling her previous life: "Faces, she thought. How strange that she couldn't remember their shapes and features. And yet the bedrooms and their decor stood out vividly. The feel of the mattress, the design on the wallpaper, the fixtures in the adjoining bathroom, were still etched in her mind along with the different types of beams and plaster she had recorded on the ceilings." Cannot clearly understand the last part of the last sentence - what are these "types of beams and plaster" which can be "recorded on the ceilings"? Seems somehow illogical... In advance, thank you for your answers!
