i need to understand the point towards complicating the whole chess board making process and then performing certain calculations (when choosing 4 squares) without clarifying what they were and how did we arrive at those figures while calculating?
why do we need to keep the previous mesh data when every single mesh we create will automatically come with the mesh data ?
It is about education, not a simple do this to make a chess board. It would be very easy just to list a set of instructions to make a chess board in one way. Many parts of the course use methods that may not be the ‘best’ but as ways to teach the basic methods for understanding. The board could just be made with an array modifier, but it is early on the course to introduce that yet.
If you add a Cube, you’re adding an object to the scene.
Objects have many properties, location, scale, materials, and also mesh data.
This mesh data is part of the object and not the object itself.
This MESH data contains the vertices, edges and face information.
The MESH can be exchanged for other mesh or shared, as in a LINKED DUPLICATION, between other OBJECTS.
As NP5 states, some steps in doing things with Blender. Is purely for learning purposes. Many things in Blender can be done differently. There is no right or wrong in Blender.
Have fun!
