Vocab Review 4

• Displacement Mapping- alternative computer graphics technique in contrast to bump mapping, normal mapping, and parallax mapping, using a height map to cause an effect where the actual geometric position of points over the textured surface are displaced
• Bump Mapping-  simulates bumps and wrinkles on the surface of an object
• Rendering- generating an image from a 3D model
• Alpha Channel- combining an image with a background to create the appearance of partial or full transparency
• NURBS vs Polygon- NURBS are the representation of curves and surfaces. Polygons are plane figures
• Tiling- the process of subdividing an image by regular grid
• Skinning-   used to change deformations
• Aperture- is a hole or an opening through which light travels
• Shutter Speed- The amount of light that reaches the film or image
• Focal Length- Camera lens focal lengths are usually specified in millimetres
• 
• Dolly- a film sequence
• 
• Pan- a type of computer network
• 
• Roll Aspect Ratio-  A long wing has higher bending stress for a given load than a short one and therefore requires higher structural design specifications
