Cheetah3D is a powerful and easy-to-learn 3D modeling, animation, and rendering software designed specifically for macOS. With its intuitive user interface, efficient modeling tools, and excellent rendering engine, it has become the choice of many 3D enthusiasts, designers, and artists. This article will take an in-depth look at its core interface and guide you through the complete workflow from project creation to final export.

I. Detailed Overview of the Core Interface and Workspace

Cheetah3D’s interface design is compact and efficient, mainly divided into the following core areas:

1. Main Menu Bar and Toolbar: Located at the top of the window. The toolbar contains the most commonly used tools, such as select, move, rotate, scale, and create basic geometric primitives.
2. 3D Viewport: Occupies the center of the interface and is the main window for observing and manipulating your 3D scene. It is displayed in perspective view by default, and you can switch to orthographic views such as top, front, and right using the tabs above the viewport.
3. Object Browser: Usually located on the left side of the interface. It clearly displays all objects in the scene (models, lights, cameras, etc.), materials, and tags in a tree structure. This is key to managing hierarchical relationships in complex scenes.
4. Property Manager: Usually located on the right side of the interface. When any object, tool, or material in the scene is selected, all of its adjustable parameters are displayed here. This is the core panel for precise control and modification.
5. Animation Timeline: Located at the bottom of the interface. Used to create and edit keyframe animations, control animation playback, set keyframes, and adjust animation curves.
6. Coordinate and Information Display Bar: Located at the bottom of the window, displaying the cursor coordinates, selected object information, and operation hints in real time.

II. Complete Workflow: From Creation to Export

1. Create or Open a Project

Steps:

1. Launch the software: Double-click the Cheetah3D application icon.
2. Create a new project: After the software launches, a blank scene is created automatically. You can also create a new project via the menu bar File > New or by using the shortcut Cmd + N.
3. Open a project: To open an existing file, go to the menu bar File > Open... or use the shortcut Cmd + O, then select your .jas project file in the dialog that appears.

2. Modeling and Object Editing

Steps:

1. Add basic objects: Click the geometry icons on the toolbar (such as cube, sphere, cylinder), or select from the menu bar Objects > Primitives to create the object at the origin of the viewport.
2. Select Object: Click the object name in the 3D viewport or Outliner. Use the Cmd key for multi-selection.
3. Transform Object:
   • Move: After selecting the object, press the shortcut W to activate the Move tool, then drag the axis arrows.
   • Rotate: Press the shortcut E to activate the Rotate tool, then drag the rotation rings.
   • Scale: Press the shortcut R to activate the Scale tool, then drag the center cube for uniform scaling, or drag the axes for single-axis scaling.
4. Enter Edit Mode: For polygon models, double-click the object in the Outliner, or select it and press the shortcut Tab to enter vertex, edge, and face editing mode. Press Tab again to exit.
5. Use Modeling Tools: In Edit Mode, use tools such as Extrude, Bridge, Knife, etc. from the Tools menu bar or the right-click context menu to sculpt details.

3. Material and Texture Assignment

Steps:

1. Create Material: At the bottom of the Outliner, click the + icon and select “Material”. A new material sphere will appear in the Outliner.
2. Edit Material: Select the material sphere, and the property manager on the right will display all its channels (color, diffuse, specular, bump, etc.). Click the “…” button to the right of a channel to load an image texture.
3. Assign Material: Drag the material sphere directly from the Object Browser onto the target object in the 3D view, or drag it onto the object’s name in the Object Browser.
4. UV Unwrapping: For complex models, you need to unwrap UVs to map textures correctly. Select the model, use the menu bar UV > Unwrap UV or related tools, then adjust in the UV Editor.

4. Set Up Lights and Camera

Steps:

1. Add Lights: Click the light icon in the toolbar, or use the menu bar Objects > Lights to add point lights, spot lights, parallel lights, etc.
2. Adjust Light Parameters: Select a light and adjust intensity, color, shadows (enabling “Raytraced Soft Shadows” is recommended for better results), etc. in the Property Manager.
3. Set Up Camera: The scene already has a default camera. You can add a new camera via the menu bar Objects > Camera. After framing your shot, right-click the target camera in the Object Browser and select “Set as Render Camera”.

5. Animation Creation (Optional)

Steps:

1. Enable Auto Keyframe: Click the red circle button in the upper right corner of the animation timeline to enable Auto Keyframe mode.
2. Set the Starting Keyframe: Drag the time slider to frame 0, select the object you want to animate, and modify its position, rotation, and other properties. The software will automatically record a keyframe (displayed as a red diamond).
3. Set the Ending Keyframe: Drag the time slider to the target frame (e.g., frame 60), modify the object properties again, and create another keyframe.
4. Preview the Animation: Use the playback controls on the timeline (Spacebar) to preview.
5. Edit Animation Curves: Double-click an animation parameter in the Object Browser (e.g., “X Position”) to open the Animation Curve Editor for fine-tuning.

6. Render and Export the Final Work

Steps:

1. Adjust Render Settings: Click the “Render Settings” icon in the toolbar (or Cmd + K). In the Properties Manager, set:
   • Output Size: Define the width and height of the image.
   • Anti-Aliasing: Increase quality to reduce jagged edges, but this will increase render time.
   • Renderer: Cheetah3D includes a high-quality ray tracing renderer.
2. Render Test: Click the “Render” icon on the toolbar (or Cmd + R) to perform a quick test render and preview the result.
3. Final Render: Once you are satisfied with the result, adjust the final parameters in the render settings panel and click Render > Render... in the menu bar to start the final render. The image will be displayed in a new window.
4. Save Image: In the render result window, click File > Save... or use Cmd + S, choose a format (such as PNG, JPEG, TIFF), and specify the save location.
5. Export 3D Model: If you need to export a model for use in other software, select the target model in the Outliner and use File > Export... in the menu bar. Supported formats include FBX, OBJ, DAE, STL, and more.
