Add Edges to Mesh

 Loop Cut Tool

• Go to edit mode
• The tools and icons on the right change
  • If you float over them, they tell you what they are
• You can drag the side of the icons to put them
  • side by side
  • or by seeing the name
• Icons with a triangle on the bottom right corner have sub-menus
• You can use the loop cut tool to add edges
  • Ctrl + r
    • You can see short cuts if you hover your mouse and leave it for a few seconds over the icon.
  • By default, it is in the middle of the two parallel edges
    • If you left click the mouse button and hold and drag, you can position where it goes
• When you let go of the left click and have the edge loop, there is a menu on the bottom left to configure things like the
  • number of cuts....

Edit Multiple Objects and Workspaces

 Edit mode

• Ctrl + Tab select in wheel the mode
  • Can use numbers hotkey in keyboard and numpad
• Tab to go to toggle edit mode
• Shift + a to add objects with pop-up menu
• Can create multiple objects and edit them

 Workspaces

• There are pre-defined workspaces.
  • They are not new modes, they are just custom layout streamlined for your workflow
• You can duplicate a workspace, rename it and customize it
• Switching modes go to edit the selected objects in the contextual edit mode

Modeling tools introduction

• You can toggle to the orthographic view, click on the grid in the top right corner of the viewport.
  • Perspective view is when there is a vanishing point
  • Orthographic view does not have this vanishing point
• Polygon tools only works on meshes
• Must be in edit mode
  • You are deforming and manipulating
    • vertices (points, verts)
    • edges (lines, sides)
    • polygons (faces)
• You can't select other objects while in edit mode
• You can go into edit mode from
  • the top drop down
  • Ctrl + Tab
    • Tab only will toggle Object Mode and Edit Mode
  • 1, 2, 3 on the top keyboard
    • 1 vertices
    • 2 edges
    • 3 polygons
• You can select the component in edit mode
  • vertices
  • edges
  • polygons
• NOTE: You...

Polygon Mesh - Drawing Polygons in Blender

• Create a mesh object
  • Lets use a plane
• Go into edit mode and delete all vertices
• Go to top view
  • 7 on the numpad
  • Hold alt and orbit in viewport to snap to a view
  • Click on the positive z-axis in the top right corner
• To add a vertex
  • Ctrl + Right Mouse Button Click in Edit Mode
  • NOTE: If the last vertex is selected it will draw a edge
    • You can click an empty area in the viewport to unselect
• Select all the vertices and press the f button to create a face
• Can check orientation of faces with Overlays -> Geometry -> Face Orientation
  • Make sure Overlays is enabled
  • Make sure backface culling is off
• You can check backface culling with ...

Polygon Mesh - 3D Coordinates

• There are 3D coordinates based on the XYZ axis

  • There are different conventions in fields and software
    • What axis is up
    • Positive values
    • Right hand and left hand rule
    • Units
    • Clock-wise or counter clockwise

• Normal is perpendicular to the surface

  • Good for light
    • fresnel effect

• UV texture

• Different types of modeling

  • NURBS (non uniform rational basis splines)
    • Was popular for a time because it was smooth/organic (not hard) surface
    • Less intuitive (points were not on the surface)
    • More abstract
    • Due to computation, not always accurately designed

• Polygon modeling based

  • Look very blocky (or faceted)
  • Computationally expensive and a lot of RAM to deal with all these points
    • Not so these days
  • Now, we can have a lot more points

What does it consists of

• Points, or vertices (plural of vertex)
• Edges
• Faces (can be called a polygon)
  • All polygons are made of triangles
