Cartesian Co-ordinate System
What system do 3D software packages use to create the illusion of working in three-dimensional space?
The system used to create illusion in three dimemsional space is the Cartesian coordinate system which is the same system use to teach algebra, the cartesian coordinate system is used to determine each point uniquely in a plane through two numbers, usually called the x-coordinate or abscissa and the y-coordinate or ordinate of the point..
Who developed the system used to create the illusion of working in three dimensional space?
A French Mathematician “Rene Descartes”.
What are the two axes that commonly define the 2-dimensional Cartesian system?
The horizontal axis X. The Vertical axis Y.
The Point where the XY axes meet is known as the?
Origin. Point 0.
What is the importance of the Z axis?
The Z axis is called the depth axis and it allows us to locate any point in 3D space.
Write the following point using the Format (XYZ)
· 59 units along the negative X-axis· 100 units along the positive Y-axis· 50 units along the negative Z-axis
-59,100,-50
What is the purpose of the viewports?
The viewports present a more 3-dimensional view because it displays all three axis at the same time (X, Y and Z)
What is an Orthographic View?
The orthographic (or schematic) is the Top, Front and left views
