Transcript:
this tutorial we will learn to manipulate objects in Blender
everything will be explained in this tutorial
happen in Object Mode
mode of object manipulation
before anything else,
need to understand how the system of axes in a 3D environment
pressing the keypad 7
go to the Top view
Imagine a drawing done by hand on paper
it has two dimensions,
symbolized by the letters X and Y
forming the 2D coordinate system
as a standard, 2D coordinates
are calculated from the bottom left
and bottom-up
this applies to most programs
that use the 2D coordinate system
if we, for example, measure the height of one
we always start from the bottom up
not unlike
this concept has always been used by
great artists of history
and for this reason, programs such as Blender use
some programs like Photoshop and Corel Draw
reverse this pattern by calculating the coordinates
based on the upper left
and top to bottom
it for easier viewing
the size of objects on the monitor
but this is an exception to the rule
in our case, the green arrow represents the Y axis
that defines the height
and the red arrow represents the X axis
that defines the width of the cube
the fact is that we are in a 3D program
and enter a 3D view
perceive the existence of a third blue axis
called the Z axis
and represents the depth of our cube
is precisely the presence of this third axis depth
which defines the third dimension
to add new objects, press Shift + a
and add the menu will appear
objects in this menu are available in Blender
separated into groups
the first group are the primitives
the second, the objects of deformation
the third, the configuration objects of the environment
and the fourth group, the physical objects and automation
Mesh objects are vector nets
used as a basis for modeling complex objects
Curve objects are vector curves
that can be used to design logos
or 2D shapes, to be later transformed into 3D
Surface objects, surfaces are vector
that can be used to model forms
Metaball objects are special objects
that blend with each other to collide
Text objects are blocks of text
that can be easily edited and formatted
Armature objects, are subject to joint
used to create hinges
how the bone structure of a character
or any type of joint
Lattice objects are containers
that deform objects
that are within its bounding area
imagine the lattice objects
like a plastic bag full of candy
that when folded, fold the candy that is also inside
Empty objects
are used along with other objects
to assist in the dynamic manipulation of specific parts of the mesh
the Camera object, the object is filming the environment
the rendering process uses the camera
to capture the scenes and produce images or animations
Lamp objects, are responsible for lighting the scenes
Force Field objects are special objects
that simulate physics effects such as wind, magnets, cyclones, etc.
Group Instance objects,
are instances of objects grouped
that can be added
as many times as necessary
we understand how they work
later in the tutorial sequence
