Explanation about the drawings.
JB3D is a hobby-company that makes drawings on computer in 3D.
How does it work?
Drawing on computer is different from drawing on paper. Paper is flat. That is why you can only draw in two dimensions. For instance you draw the floorplan of a house first. Afterwards you draw the different sides. Most people have problems to imagine how this house looks in our real 3D-world.
That’s where computerdrawing comes in.
In programs like Blender 3D you can put three dimensions in one drawing. Than you can colour and texture your objects and assign lights to it. That’s how an imaginary world grows. In that world you can take your position and you can see how it looks like from that point. You can even go further and make animations.
That’s the way the pictures beneath came into being.
