TD 3D Modeling

• 3D models are made within a computer-based 3D modelling software.
• A 3D model is essentially made up of vertices, which come together to form a mesh and act as the core of the 3D model.
• By using coordinate data, the software identifies the location of each vertical and horizontal point, all relative to a reference point.
• The most common way to begin making a 3D model is to start with a basic shape
• Opening blender, you are faced with a toolbar to the left an right, file operations to the top, timeline on the bottom, and the 3D view in the center.
• To rotate around in the 3D view, hold down the middle mouse button and move the mouse.
• Notice that when you select something, it will be highlighted orange
• Object Mode lets you select objects and move them around as you please.
• Edit Mode allows you to select individual vertexes, lines, and planes. you can modify the mesh in this mode
• to switch between object and edit mode you can either go down to the menu below, or just press TAB
• The red arrow is the X axis, green is the Y axis, and blue is the Z axis.
• Rotating is very simple, all you have to do is select the object to be rotated, and press "R"
• To scale an object, simply press "S". if you want to stretch an object along a certain axis press "X", "Y", or "Z", after pressing "S
• In edit mode there are three ways to select things, you can either select individual vertexes, lines or planes.
• In edit mode you can select two or more verteces and merge them together
• In edit mode, you can select a line, vertex, or plane, and extrude, or, extend it
• Loop sliding allows you to make a "cut" in a mesh, letting modify it further.
• Modifiers modify your mesh
• "subdivision surface" modifier.
