How do 3D models for virtual worlds come about?

3D modeling is the process of creating three-dimensional objects in a computer using certain software. These objects can be anything from space and objects in the real world to fantastic and futuristic creations. It is used in a variety of industries including design, architecture, film and video games. Designers use 3D modeling to create precise and realistic models, while architects use this technology to create virtual representations of future projects. Modeling characters or objects for virtual worlds like Roblox or Somnium works in an identical way.

3D modeling software usually has various tools and functions that allow users to create and manipulate 3D objects. Some of the most commonly used are e.g. Blender, Maya, or Autodesk's 3ds Max. These tools include the ability to draw surfaces, add texture and color, as well as create animations and interactive models. When the 3D model is finished, it is saved in a format compatible with the virtual world system or VR software. For Unity purposes, it is usually fbx, and VRML and OBJ file formats are still common. Generally speaking, for the purposes of VR devices, models are extremely detailed and precise in order to achieve the most immersive experience.

How to start with 3D modeling?

1. Choose the right 3D modeling software. There are many different options on the market, from free programs like Blender to professional tools like 3ds Max or Maya. Choose one that suits your needs and skills.
2. After you have installed and run the software, look for tutorials and online resources to help you familiarize yourself with the tools and functions of the program. These tutorials usually cover the basics of 3D modeling, such as drawing surfaces and adding texture and color.
3. When you are familiar with the basics, try to create your first 3D model. You can start with a simple object, such as a ball or a cube, and use the tools in the software to refine it and add details.
4. When you're happy with your first 3D model, try animating it or integrating it into virtual reality. These steps may require additional learning and exploration, but they can give you even more opportunities and experiences with 3D modeling.
5. After mastering the basics of 3D modeling, continue learning and exploring new techniques and tools. This will help you improve your skills and create increasingly complex and realistic models.
