Learn Blender terms through bpy

For developers learning Blender with an agent. Blender terms, bpy code, and real renders made with Blender 5.1.1.

From the interface to code

Each image was rendered from a bpy script in Blender 5.1.1.

···

Mirror modifier미러 모디파이어

Model one half and this modifier flips a copy onto the other side — the usual starting point for symmetric models.

···

Roughness거칠기

A 0–1 value for how smooth a surface is: 0 gives mirror-sharp reflections, 1 spreads light like chalk.

···

Keyframe키프레임

A marker that records a value at a frame. Blender fills in the values between two keyframes.

Motion & automation

▣Interface & modes

The 3D Viewport, Outliner, Edit Mode — the names you see on first launch, and how each screen action maps to Python.

View all (11) →

···

3D Viewport3D 뷰포트

The work area for viewing, moving, and making objects. The same scene can be modeled, animated, and painted here.

···

Viewport Shading뷰포트 셰이딩

A set of display modes for the 3D Viewport, from checking shape to previewing materials and lighting.

···

Outliner아웃라이너

A hierarchy of a scene’s collections and objects, used to select, rename, and organize them.

···

Properties Editor속성 에디터

Tabbed settings for the selected object and scene. Values are stored in data and can affect the render.

⊹Objects & transforms

Location, rotation, scale, origin, parenting, collections — the basics of placing, grouping and organizing things in a scene.

View all (11) →

···

Transform트랜스폼

Three values decide where an object sits, how it turns, and how large it appears. In Object Mode, the origin and mesh move together.

···

Object Origin오브젝트 원점

The point that locates an object and anchors its rotation and scale. It can sit somewhere other than the mesh center.

···

Pivot Point피벗 포인트

The point used to rotate or scale a selection. Unlike an object origin, it can change per operation: median, cursor, or each origin.

···

Snapping스냅

Snapping constrains moves, rotations, or scaling to a grid or nearby geometry, so precise placement depends less on mouse feel.

⬡Mesh editing

Extrude, inset, loop cut, knife — Edit Mode tools that change vertices, edges and faces, plus the bmesh code that does the same.

View all (12) →

···

Extrude돌출

Extends selected faces, edges, or vertices into new geometry and connects the sides.

···

Inset Faces면 삽입

Creates a smaller face inside the selection, leaving a border for frames and panels.

···

Loop Cut루프 컷

Adds a continuous edge ring across quad faces, giving precise control over where a form bends.

···

Knife and Bisect나이프와 이등분

Knife cuts along a drawn path; Bisect cuts a mesh with a plane.

⧉Modifiers

Mirror, Array, Boolean, Solidify — stack non-destructive effects that change the result while the original mesh stays untouched.

View all (18) →

···

Modifier stack모디파이어 스택

An object’s modifiers evaluate from top to bottom. Reordering them can change the result even when the modifiers stay the same.

···

Apply Modifier모디파이어 적용

Apply bakes a modifier’s evaluated result into the mesh and removes it from the stack. You can no longer revise the operation by changing its settings.

···

Mirror modifier미러 모디파이어

Model one half and this modifier flips a copy onto the other side — the usual starting point for symmetric models.

···

Array modifier배열 모디파이어

Repeat one piece in a line, circle, or other layout. Blender 5.1’s current Array is Geometry Nodes based; the older one is labeled Legacy.

⋈Geometry Nodes

Distribute points, instance, set position — build shapes procedurally by wiring nodes, and script those node trees.

View all (12) →

···

Geometry Nodes Modifier지오메트리 노드 모디파이어

A modifier that builds and changes object geometry procedurally through a node tree. It reevaluates the result from its input without baking changes into the source mesh.

···

Distribute Points on Faces면에 점 분포

A Geometry Nodes node that places points across mesh faces using a chosen method and density. Those points can anchor objects such as grass or pebbles to a surface.

···

Instance on Points점에 인스턴스

A node that places a reference to source geometry at each point instead of making full copies. Rotation and Scale fields control the orientation and size of each placement.

···

Realize Instances인스턴스 실현

A node that turns instance references into real geometry. Later mesh operations can then work on each copy’s points and faces, at the cost of more memory.

∿Curves & text

Bézier curves, bevel depth, extruded text — make shapes from lines and letters, then convert them to meshes.

View all (8) →

···

Bézier curve베지어 커브

A curve shaped by a few control points and handles. Move a point or adjust its handles to refine the path.

···

Curve bevel커브 베벨

A cross-section swept along a curve to give the path thickness. Increase the value to turn a thin line into a tube.

···

Control-point radius taper제어점 반경 테이퍼

Sets each control-point Radius on a beveled curve to vary thickness along the path. This example narrows both ends to 0.08.

···

NURBS curveNURBS 커브

A spline computed from control points and weights. It is shaped by nearby points rather than necessarily passing through every one.

◐Materials & shaders

Principled BSDF, roughness, metallic, transmission — the values that decide how a surface takes light, and wiring shader nodes in code.

View all (16) →

···

Principled BSDF원리 BSDF

One shader node combines surface properties such as color, metalness, roughness and transmission.

···

Base Color기본 색

The Principled BSDF color input that tints its diffuse, metallic and transmissive layers.

···

Roughness거칠기

A 0–1 value for how smooth a surface is: 0 gives mirror-sharp reflections, 1 spreads light like chalk.

···

Metallic금속성

Blends the Principled BSDF from a dielectric toward a metal, whose reflections take on the base color.

☀Lights & world

Point, sun, spot and area lights, HDRI worlds, three-point lighting — how a scene is lit and what shapes its shadows.

View all (11) →

···

Point Light점광원

A point light sends light in every direction from one position, like a bare bulb. The direction and brightness on a surface change with its distance from the source.

···

Sun Light태양광

It sends parallel light in one direction, like a distant sun. Its position does not affect the scene; its rotation sets the direction.

···

Spot Light스포트라이트

It sends light from one point inside a cone. Set the cone angle and edge softness to control the lit area.

···

Area Light면광원

A light emitted from a surface. Its size and shape affect highlights and the softness of shadow edges.

◎Camera & render

Focal length, depth of field, EEVEE vs. Cycles, samples, denoising, color management — the settings that turn a scene into an image.

View all (13) →

···

Focal Length초점 거리

Focal length sets how wide a view the camera captures. With the camera fixed, a longer lens shows a narrower part of the scene at a larger size.

···

Depth of Field피사계 심도

Depth of field blurs areas in front of and behind the focus distance to draw attention to a subject. Set the focus target and aperture to control the blur.

···

Orthographic Camera직교 카메라

An orthographic camera projects without perspective. Distant objects keep the same apparent size as nearby ones, which suits technical views.

···

Render Engine렌더 엔진

A render engine is the method Blender uses to turn a scene into an image. Workbench, EEVEE, and Cycles differ in speed and how they calculate light.

◇Animation

Keyframes, interpolation, F-curves, drivers, shape keys — changing values over time, and the slotted Actions of Blender 5.x.

View all (11) →

···

Keyframe키프레임

A marker that records a value at a frame. Blender fills in the values between two keyframes.

···

Interpolation보간

Interpolation defines how values are filled between keyframes. The same two keys can produce different speeds and arrival times.

···

F-CurveF-커브

A curve that maps frames to one animated value. Edit its keys and interpolation in the Graph Editor.

···

F-Curve ModifiersF-커브 모디파이어

Add rules such as repetition or noise to an F-Curve without changing its keys. Motion can continue without duplicating keys.

⟟Rigging & physics

Armatures, weights, IK, rigid bodies, cloth, particles — move things with bones and let simulations drop them.

View all (10) →

···

Armature아마추어

A hierarchy of bones and joints that moves a mesh. A pose change travels through the hierarchy and deforms the bound mesh.

···

Vertex Groups정점 그룹

Named sets of mesh vertices with per-vertex weights. Armatures and modifiers use them to decide which vertices they affect and by how much.

···

Weight Paint웨이트 페인트

An editing mode that paints vertex-group weights as colors. It helps reveal which parts of a mesh each bone will move and by how much.

···

Inverse Kinematics역운동학

A constraint that solves connected joint rotations backward from a target position for the chain endpoint.

›_Python & pipeline

bpy.data vs. bpy.ops, background renders, append and link, glTF export — running Blender from code and the command line.

View all (13) →

···

bpy.data vs bpy.opsbpy.data와 bpy.ops

bpy.data edits scene data-blocks directly. bpy.ops runs Blender actions and depends on the current selection and context.

···

Context Override컨텍스트 오버라이드

Temporarily supplies the active object or selection an operator needs, without changing the user's current selection.

···

Background Rendering백그라운드 렌더

Blender evaluates and renders a scene without opening its window, which suits servers and batch jobs that produce files unattended.

···

Command-Line Arguments명령행 인자

Pass numbers, paths, and options at launch instead of editing the script. The -- marker separates Blender flags from script arguments.
