Basics of 3D Animation - Co-ordinate system

Third Dimension (3D) computer graphics is ‘2 dimensional portrayal of the simulated 3D world’. It is the virtual world we see around us.
While transferring 2D image in third dimension; a z-coordinate axis has to be added along with the default ones i.e. x-axis and y-axis. In addition to this, we just don’t create objects in 3D; but we have to generate the 2D images of the 3D scene which will resemble the 3D objects.

In a particular scene; the scale, rotation and position of an object can be altered. The object coordinate system is suitable for the object that is being created. The coordinates which is used to create the complete scene with objects is called the World coordinates. After creating the scene the output can be taken in the form of an image.
