Deforming 3D Models: A Practical Tutorial

Deforming 3D models lets you create organic motion, apply sculptural changes, or adapt geometry procedurally. This tutorial covers foundational techniques, tools, and a step-by-step workflow you can use in Blender (free) or similar 3D software. Follow along to learn basic deformers, mesh-weighting, and a simple animation example.

• Operating System: Windows 10 (64-bit) or macOS High Sierra (or later)
• Processor: 64-bit Intel or AMD processor (quad-core or higher)
• Memory: 8 GB RAM (16 GB or more recommended)
• Graphics: NVIDIA GeForce GTX 1060 or AMD Radeon RX 580 (or higher)

Step-by-step: Animated Squash-and-Stretch (Blender)

1. Scene setup: add a UV sphere (Shift+A → Mesh → UV Sphere). Apply transforms (Ctrl+A → All Transforms).
2. Subdivide: add Subdivision Surface modifier (Levels 2 viewport). Add Shade Smooth.
3. Add Shape Keys: in Object Data Properties, click '+' twice to create Basis and Key 1. With Key 1 selected, go into Edit Mode and scale the sphere along Z (S → Z → 0.6) and compensate by scaling X and Y up (S → Shift+Z → 1.2) to create a squash pose. Exit Edit Mode.
4. Animate shape key influence: insert keyframes for Key 1 value at frame 1 (0), frame 10 (1), frame 20 (0). Use Graph Editor to add ease in/out or a custom curve for bouncy timing.
5. Add a slight stretch at contact: duplicate Key 1 for a stretch shape or use a second shape key focused on Z stretch. Blend both keys to compose squash-and-stretch.
6. Add secondary motion: parent a soft-body or lattice to the sphere for subtle wobble; animate influence to fade.

1. Scaling: Resize an object using the Scale tool (Ctrl + Shift + S (Windows) or Command + Shift + S (Mac)).
2. Translation: Move an object using the Move tool (Ctrl + Shift + M (Windows) or Command + Shift + M (Mac)).
3. Rotation: Rotate an object using the Rotate tool (Ctrl + Shift + R (Windows) or Command + Shift + R (Mac)).

Database Generation: Generate the keyword file and start the simulation engine. Post-processing (Results) Analyze the equivalent stress, strain, and material flow. deform 3d tutorial
