Two-dimensional shapes have dimensions, such as length and width, while three-dimensional shapes have an additional dimension, such as height. Any shape that only has a surface area is a 2-D shape while shapes with volume are 3-D shapes.
By examining the units of area, inches-squared or an equivalent unit, it is clear that an area measurement is an example of a 2-D measurement. Likewise, volume is a 3-D measurement based on units of inches cubed. While the surface area of a 3-D shape can be determine, there is no volume to a 2-D shape. Only calculations or a lower order can be performed on any given shape.Learn More
2-D design applies two dimensions: length and width. Several elements and principles of art can be applied to 2-D design to make the simplest image more interesting and complex.Full Answer >
On a scaled drawing, the ratio 1:100 defines the relationship between the length on the drawing and the length in real life. For example, a length of 1 centimeter on the drawing means that the length of the object in real life is 100 centimeters.Full Answer >
Three-dimensional animation is taking three-dimensional objects, either real or virtual, and making them move. As of 2014, 3-D animation typically involves computer-generated imagery, but the original 3-D animation was stop-motion or claymation serial photography of solid objects moved slightly between each picture, which was then strung together creating animated action.Full Answer >
CAD or Computer-aided design is the use of software to create two- or three-dimensional designs, while CAM, computer-aided manufacturing, is the use of computer software and machinery to manufacture three-dimensional objects. For CAD users the end product is a design or image. For CAM users the end product is an object.Full Answer >
