Notes

Certainly, I can explain these terms:

a) **Foreshortening:**
- Foreshortening is an artistic technique used to depict objects or figures in a picture or drawing in a way that accurately represents their depth and perspective. It involves showing objects that are closer to the viewer as larger and those farther away as smaller. This technique helps create a sense of three-dimensionality in two-dimensional artwork, making objects appear as if they are receding into the distance. Foreshortening is commonly used in fields like painting, drawing, and illustration to achieve realistic depth and perspective.

b) **Planar Projection:**
- Planar projection is a method used in computer graphics, computer-aided design (CAD), and mathematics to represent three-dimensional objects on a two-dimensional plane, like a computer screen or paper. It involves mapping points, lines, and surfaces from a 3D space onto a flat surface. Different projection techniques, such as orthographic and perspective projections, are used to accurately visualize and work with 3D objects in 2D spaces. Planar projection is fundamental in fields like engineering, architecture, and computer graphics for modeling and design purposes.

c) **Biometry:**
- Biometry, also known as biostatistics or biometrics, is a branch of science that applies statistical and mathematical methods to analyze and interpret data related to living organisms. It involves collecting and processing data from biological and life science studies, such as genetics, epidemiology, ecology, and medical research. Biometric techniques are used to draw meaningful conclusions, make predictions, and conduct experiments in these fields. It plays a crucial role in understanding and addressing various biological and health-related phenomena.

d) **Field of View (FOV):**
- The field of view (FOV) refers to the extent of the observable world or scene that can be seen at any given moment through a visual or optical device. It is typically measured in degrees or angular units and represents the area or angle within which an observer or instrument can capture information. In photography, a wide field of view captures more of the scene, while a narrow field of view focuses on a smaller portion with greater detail. In scientific instruments like microscopes and telescopes, the field of view affects the amount of a sample or celestial object that can be observed simultaneously. FOV is a critical parameter in various imaging and observational contexts.
