Box/Subdivision Modeling

Box modeling, or subdivision modeling, is a versatile technique that allows you to start with a simple shape and add detail incrementally. Tools like Autodesk Maya, Blender, or 3ds Max provide robust box modeling capabilities. Begin by creating a basic shape such as a cube and use subdivision algorithms to refine and sculpt your model's structure.

Procedural Modeling:

Procedural modeling allows you to generate complex models using algorithms and rules. Tools such as Houdini, Substance 3D Designer, or World Machine are great for these use cases. In this workflow, you define parameters and algorithms to create intricate structures programmatically. This technique offers great flexibility, enabling quick iterations and dynamic customization, however it is quite complex to learn and takes a deep knowledge in math and modeling techniques.

3D Scanning and photogrammetry:

3D scanning captures real-world objects or environments using specialized equipment. Tools like RealityCapture, Agisoft Metashape, or Autodesk ReCap provide efficient 3D scanning capabilities. Scan physical objects or environments to generate highly realistic models. After scanning, you can optimize the resulting high-polygon models using mesh simplification or retopology techniques.

Digital Sculpting:

Digital sculpting allows for meticulous shaping and detailing of 3D models. Tools like Pixologic ZBrush, Blender, or SculptGL offer powerful digital sculpting features. Sculpt intricate details and organic forms, breathing life into characters and objects. With digital sculpting, you can achieve remarkable realism and unleash your artistic vision.

AI-Generated 3D Models:

AI is revolutionizing the industry, providing huge efficiency boosts and cost savings. With tools such as Sloyd, you can create 3D models effortlessly, reducing or eliminating the need for manual creation or outsourcing. These models can also serve as a starting point for traditional 3D modeling, combining AI efficiency with human creativity in an effective way. Sloyd combines parametric models with AI to make sure you get quick results that are optimized and ready to use.
