Techniques

Origin

Consider scaling a lamp on a desk: Want the lamp to stay on the desk, not go below the desk.
→ Enable 3D Viewport Pie Menus add-on in preferences(Edit → Preferences or F4 → p)

Camera

• Alt-R clear rotation

Bezier Curves

• Alt-C close curve
• F fillgap between two vertex points
• V set handle type (auto, vector)
• W subdivide - insert new point between selected
• X, Select - remove a point
• X, Segment - cuts curve between two selected points
• Preferences → Themes → Light Theme — curves show up better
• Preferences → Add-ons → Add Curve: Curve Tools
• Preferences → Add-ons → Add Curve: Extra Objects
• Colorized Handle Functions
  • Automatic: → smooth flowing curve
  • Vector: → linear, straight line
  • Aligned: → locked to other handle
  • Free: → corner type or free angle
  • "toggle free aligned" → ???

Backdrop in Node Compositor

• V zoom out
• Alt-V zoom in
• Alt-MMB pan
• Ctrl-LMB,drag to cut a connection between nodes
• Shft-LMB,drag over a connection to create a reroute node (splitter)
• H collapse selected node

Make an emitting plane:

• Cycles - Give you plane an emission shader
• Blender render - In material settings increase emit value
• In World enable Indirect Lighting and set Gather to Approximate

Make curtains

• Add a new mesh, Grid, and set the divisions to something divisible by 3, say 54
• Tab into edit mode and rotate to vertical
• Select the top left vertex, skip two vertices, shift select
• Press Ctrl Shift numpad plus to repeat to last vertex on top right
• In object properties, add a new vertex group called pinned vertexes, and click assign
• still in edit mode, press Ctrl H and select hook to new object to tie these vertices to a new empty
• Tab into object mode, right click and shade smooth
• In physics properties, add a cloth physics
• still in physics, open shape menu, and add the vertex group, pinned vertexes, to the Pin Group
• below that,

Architectural Model

• Enable built in add-on called Import Images as Planes
• Import the reference image Shft A → Image → Images as Planes
  • Be sure Viewport Shading is set to Material Preview
• Scale the reference image
  • Set units (metric vs imperial) in View Properties
  • Add a vertex and then edit mode to extrude it to a known length in the reference image
