In 3D graphic the most important and basic of all the things is to learn what XYZ coordinates are? All the work in 3D graphics whether it is 3D modeling of images or 3D animated videos or 3D calligraphic designing all of them circle around XYZ coordinate system.
Here you can learn about XYZ coordinates in detail. You will be taught what frame of references means in XYZ coordinate system. There is reference point of each point in XYZ coordinate system. It is like that “a book is placed on a table“then table will be called as a reference to find the book in a room this should be taken as an example to describe the meanings of reference. Similarly, every point in work space of Maya has it reference with respect to origin. In XYZ coordinate system the origin is a fixed point from where the X, Y and Z coordinates originate. Learn XYZ coordinate system in Maya graphics in a very comprehensive manner on our website. You will then be able to draw Graphics in Maya 3D graphics like a professional.
