Accuracy Vs. Precision |
-Accuracy is how close a measured value is to the actual value -Precision is how close the measured values are to each other |
|
What is Orthographic Projection |
A 3 dimensional object shown using several 2 dimensional planes(However many is necessary to accurately show object) |
|
What is Isometric Projection |
A 3 dimensional object shown with 3 visible sides of the object from the same angle to each other. |
|
Describe Perspective Projections |
Type of projection that represents objects as we see them or as they would appear in a photograph |
|
Describe Parallel Projections |
Type of projection that projectors are parallel with object |
|
Describe Orthographic Projection in respect to Parallel Projections
|
Parallel projectors are perpendicular to the plane of projection |
