I am trying to decompose 3D object (eg. Bunny) into primitive shapes basis functions.Orodruin said:It is not very clear what you mean by "representing 3D objects into primitive shapes".
Primitive shapes are basic geometric shapes, such as cubes, spheres, cylinders, and pyramids, that are used to construct more complex 3D objects. These shapes are often referred to as "building blocks" because they can be combined and manipulated to create a variety of objects.
Primitive shapes are used in 3D object representation because they are simple and easy to work with. They also provide a solid foundation for creating more complex objects, as they can be scaled, rotated, and duplicated to create a variety of shapes. Additionally, using primitive shapes can help reduce the number of calculations and resources needed for rendering 3D objects.
Primitive shapes can be transformed through a process called "meshing." This involves connecting a series of points, called vertices, to create a polygon mesh that defines the shape of the object. By manipulating the position, rotation, and scale of these vertices, the overall appearance of the 3D object can be changed.
While primitive shapes are versatile and can be combined to create a wide range of objects, they may not be suitable for representing highly complex objects or organic shapes. In these cases, more advanced techniques and software may be needed to accurately represent the object in 3D.
One limitation of using primitive shapes is that they may not always accurately represent the real-world object they are trying to model. This is because primitive shapes are made up of straight edges and flat surfaces, while real-world objects may have more complex curves and textures. Additionally, using only primitive shapes may result in a less realistic or detailed representation of the object.
