ACU 3ds Max key terms

A window inside the 3ds Max interface that displays the scene from a camera or orthographic direction, letting you navigate, select, and transform objects interactively.

The tall panel on the right of the interface holding six tabs for creating objects, modifying them, and adjusting hierarchies, display, utilities, and animation tools.

An ordered list of applied modifiers shown in the Modify panel; evaluation flows bottom to top, so placement order changes the final result.

The local origin an object rotates and scales around and the reference for its transform values; it can be moved, centered, or aligned independently of the geometry.

The on-screen axis handles (move, rotate, scale) used to constrain manipulation to a single axis, a plane, or all axes at once.

The axis orientation used for transforms and tools, such as World, Local, View, or Parent, chosen from the main toolbar list.

An interactive navigation widget in a viewport corner that shows current orientation and lets you snap to standard or adjacent orthographic and perspective views by clicking faces, edges, or corners.

A navigation command that rotates the view around a target point without moving scene objects, useful for inspecting geometry from any angle.

A mesh object type exposing sub-object levels (vertex, edge, border, polygon, element) plus editing rollouts for building and reshaping low-polygon models.

A mode inside an editable object that limits selection and editing to components such as vertices, edges, or faces rather than the whole object.

A procedural operation added to an object's stack that alters its geometry or properties, such as bending, smoothing, or shelling, and can be reordered or disabled.

An operation that bakes the current modifier stack result into editable geometry, removing the procedural history and reducing file complexity.

A compound operation that combines two closed objects using union, subtraction, or intersection to produce a new mesh.

A compound object tool that merges multiple operands with union, subtraction, intersection, or merge operations and keeps operands editable for later adjustment.

A modeling operation that pushes selected faces or a spline profile along a direction to add depth, commonly used to build walls, panels, and lettering.

A modifier that revolves a spline profile around an axis to create radially symmetric shapes such as vases, bowls, or table legs.

A compound object that builds a surface by sweeping one or more cross-section shapes along a path curve, with controls for scale and twist.

A subdivision modifier that smooths a low-polygon cage by adding interpolated faces, with iteration and render-iteration settings controlling final density.

A modeling approach where a coarse control cage is smoothed by algorithms to produce dense, rounded geometry that stays easy to edit.

A sub-object editing mode where transforms fall off gradually with distance from the selection, producing smooth organic deformation instead of hard creases.

A precision aid that locks the cursor or transform to grid points, vertices, edges, or other targets so objects align exactly.

The interface for creating and editing materials and maps, assigning them to objects, and previewing their appearance on sample slots.

A node-based view of the Material Editor where materials and maps appear as wired nodes, making complex shading networks easier to build and read.

A set of surface properties (color, glossiness, transparency, texture, and so on) applied to objects to control how they react to light.

An image or procedural pattern plugged into a material channel, such as diffuse color, bump, or opacity, to add detail without extra geometry.

The coordinate system that tells a texture how to wrap onto a surface; modifiers and unwrap tools adjust these coordinates for correct placement.

A modifier providing tools to lay out and edit texture coordinates on a flattened plane so painted textures align with the model's faces.

A raster image file used as a texture map, with settings for cropping, tiling, filtering, and output that affect how it renders.

A basic scene light type such as omni, target spot, free spot, or directional, offering direct control of intensity, color, and shadow settings.

A physically based light that uses real-world intensity units and distribution patterns, intended for accurate illumination and global illumination workflows.

A shadow-generation method that renders depth from the light's viewpoint; resolution and bias settings trade sharpness against artifacts like banding and acne.

A shadow type computed by tracing rays from surfaces to lights, producing accurate, sharp-edged shadows at a higher render cost than shadow maps.

Rendering techniques that simulate bounced light between surfaces, adding indirect illumination and color bleed for more realistic results.

A global illumination method that samples indirect light at points on surfaces and interpolates the results, softening shadows and adding ambient bounce.

A rendering method that follows rays from the camera into the scene to compute reflections, refractions, and shadows accurately.

The process of computing a final image or animation from the scene's geometry, materials, lights, and camera settings using a render engine.

The dialog controlling output size, frame range, file format, and engine-specific quality options before a render is produced.

A scene object that defines the viewpoint and projection (perspective or orthographic) used for rendering, with lens and clipping controls.

A stored value for an animatable property at a specific time; the software interpolates between keys to create motion.

The timeline beneath the viewports showing the current frame, keyframes, and active time segment, used to scrub and navigate animation.

The method used to calculate values between keyframes, such as smooth, linear, or stepped, which determines the pacing of motion.

A graph view of animation tracks where keys appear as points on curves, allowing precise adjustment of value, timing, and tangents.

The dialog that sets frame rate, total animation length, start and end frames, and playback speed for the scene.

An animation editor that lists tracks and keys in a spreadsheet-like layout for retiming, copying, and sliding groups of keys.

The parent-child linkage between objects, where transforming a parent also moves its children, used for rigs and assemblies.

An animation controller that drives an object's position, rotation, or scale from another object, such as linking, look-at, or path constraints.
