round corners of cube - add bevel modifier (via wrench icon)


TAB key - toggle between edit mode and whatever your prior mode was (object, sculpt, etc)

ctrl + numpad 4 pan/move your view left (etc...)


video sequence editor (VSE)  drag vid clip to timeline

  frame rate - should ideally match camara    24frames / sec is hollywood quality?
  graph editor good for sound

turquis = audio track?

shift + a show menu

Press alt key while selecting face or edges

 To get the entire seam!!!!

2 screens (separate window by holding SHIFT and left drag the upper right slashes)

  can even do image


circle to cylender - grab circles vertices (click one then "loop select"), extrude them
make face on cylender - select top ring of vertices, "fill" them (alt-F)
F to join faces to one face

inset faces

Rigging

blender video animation rigging with body parented to armature bones 

  (for computer graphics)

create some body/mesh

in object mode - add armature bone in the spine area (use xray mode to see it)

in edit mode E to extrude more bones (connected to original bone)

in object mode - select body/mesh    then select the Armature/bone structure (the LAST object selected will be parent)

then press CTRL+P (Parenting Menu)  Select Armature Deform With Automatic Weights. (the body/mesh is child of the armature)

in pose mode move stuff around and/or rotate specific bones

Add-Ins

Vorovio = shorter

Material

Texture

Material  default texture is diffuse map

Aclusion nah

Normal is pink and purple

Reflection/specularity  white is glossy

Displacement distorts geometry

Keyboard
N is background menu

Node editor

Uv unwrap to fit

Lamp change to sun lamp

tip: do glossy last (in the NODE EDITOR)

Render tab/properties

Select file format (png, avi, etc)

==================================================================
blender - background - easily set nice world background image
 by creating an "Environment Texture"
You can use many different kinds of background images,
 but the best is this beautiful 360° background image type: HDRI (High Dynamic Range Image).
These types of images are designed to wrap around your world in a spherical shape
  so no matter where you look in the scene, you still see the background image:
     (for free HDR images visit HDRI Hub)
Steps:
use the Cycles Render engine
Object Properties-> World tab-> "Surface" section > Use Nodes
click "Color" button, Environment Texture, Open/select your HDRI file
to see your background image while working on your scene,
you MUST be looking through your Camera (press Numpad 0 to switch to it)
and also you have to set the 3D Viewport Shading to Rendered:
==================================================================

Camera
select camera
 press num pad zero to see thru it
 press g to mouse move view around

press r to rotate

press rr to move also

s to size/scale
s z to resize/rescale on z axis

numpad
  7 for top view

edit - mesh - edge - subdivide  (which is kinda like knife and/or split)
 to split selected edges in two
 

there is also a div multiplier thingy

to rejoin subdivided faces into 1 single face
    you can also select multiple subdivided faces, and then in edit mode click mesh menu
       then edge  then make edge/face
   

when sculpting
  dynamic toplogy will auto split/subdivide in the area meaning manipulated/sculpted

F12 to see the rendered image/scene

use material view
 to timeline-play and SEE the materials/textures you have applied

select a camera
  then press zero on numpad to see thru camera
       press g to grab and move scene
       press g z to grab/move scene on z axis
       press g zz to move/zoom camera in and out of scene (to widen what you can see, etc)
       press numpad dot/decimal to see behind camera

Node Editor
  difussers

  good idea to put glossy node/modifier last at the end/output
  dot input/output color legend/meaning
Green = shader
Yellow = color
Gray = numeric input/output


Tabs/icons on the right
  wrench = modifiers (such as multi resolution -> subdivide)

space bar to do relevant menu wildcard search


  ============
join 2 objects
  from object mode,  select 2 objects (holding shift with right click 2 objects)

or drag in tree
into parent
to join text to an object, is a bit trickier,
  you must convert the text to a mesh (via ctrl-c twice)


 

Press alt key while selecting face or edges

 To get the entire seam!!!!

https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics

In case you're wondering, UV mapping stands for

 the technique used to "wrap" a 2D image texture

   onto a 3D mesh.

"U" and "V" are the names of the axes of a plane,

 since "X", "Y" and "Z" are used for the coordinates in the 3D space.

For example: increasing your "V" on a sphere might move you along a longitude line (north or south),

while increasing your "U" might move you along a line of latitude (east or west).

Another explanation can be gleaned from the Blender manual.

Imagine a paper 3D model of an object, e.g. a sphere,

 that is to be laid flat on a table.

Each of the 3D coordinates of the sphere

 can be mapped to the 2D coordinate on the flat piece of paper.

Blender provides another view of the vertices (coordinates)

 in the UV/Image Editor.

You can select and edit these 2D vertices

  just like in the 3D Editor window.

The purpose of this unwrapping of the coordinates is just

 to map these coordinates to images/pictures

  so that the 3D image can have a realistic looking surface

   with textures derived from these images.


==============================================
blender -export/save video file of your animation
Before making video file, render it as an image sequence first.
 If you render it directly to a video file, you can't stop/pause the render
   or there is a chance that you will get a corrupted file.

"Render" tab (left icon on the right side of screen)-
   "Output" section (near the bottom right of screen), choose:
output folder/loc
image format under the output settings
click on "Animation" (in trip icon bar near the top right)
wait for it to finished generating the images

click "Choose screen layout" (top middle of screen) -> "Video Editing"
"Add" -> "Image" (press A to Select all image files) "Add image strip"

Finally to make a video files from the images
  return to "Default" screen layout
output sections - choose video format
click "Animation" again (it converts your image files into a video file)

Bump Mapping

Via blender render

Image texture – influence

– geometry – normal

-         Bump mapping method

scripting (python)

move a sphere

import bpy
import time
sphere1positions = (0,1,1),  (0,5,5),  (0,7,7),  (0,11,11)
sphere1startPos = (0,0,0)
sphere1Obj = bpy.data.objects["Sphere"]
frameNum=0
for pos in sphere1positions:
    bpy.context.scene.frame_set(frameNum)
    sphere1Obj.location = pos
    sphere1Obj.keyframe_insert(data_path="location", index =-1)
    frameNum += 20

    time.sleep(5)
