    Granite [6] is developed by Parametric Technology Corporation. C3D Modeler is developed by C3D Labs, part of the ASCON Group. [7] [8] CGAL is an opensource Computational Geometry Algorithms Library which has support for boolean operations on Polyhedra; but no sweep, revolve or NURBS. Open CASCADE is an opensource modeling kernel.

  4. Wavefront .obj file - Wikipedia

    en.wikipedia.org/wiki/Wavefront_.obj_file

    The Material Template Library format (MTL) or .MTL File Format is a companion file format to .OBJ, also defined by Wavefront Technologies, that describes surface shading (material) properties of objects within one or more .OBJ files. A .OBJ file references one or more .MTL files (called "material libraries"), and from there, references one or ...

  5. PLY (file format) - Wikipedia

    en.wikipedia.org/wiki/PLY_(file_format)

    The file starts with the header which defines a file in ASCII format. There are 14 vertices (6 faces * 4 vertices - 10 vertices saved due to merging) and 6 faces in total. After the header, the vertex and face data is listed. The vertex list contains position (x,y,z), normals (nx,ny,nz) and texture coordinates (s,t) for each of the 14 vertices.

  6. Hexadecagon - Wikipedia

    en.wikipedia.org/wiki/Hexadecagon

    There are three regular star polygons, {16/3}, {16/5}, {16/7}, using the same vertices, but connecting every third, fifth or seventh points. There are also three compounds: {16/2} is reduced to 2{8} as two octagons , {16/4} is reduced to 4{4} as four squares and {16/6} reduces to 2{8/3} as two octagrams , and finally {16/8} is reduced to 8{2 ...

  7. Polygon mesh - Wikipedia

    en.wikipedia.org/wiki/Polygon_mesh

    Generally materials will be defined, allowing different portions of the mesh to use different shaders when rendered. UV coordinates Most mesh formats also support some form of UV coordinates which are a separate 2d representation of the mesh "unfolded" to show what portion of a 2-dimensional texture map to apply to different polygons of the mesh.

  9. Polygonal modeling - Wikipedia

    en.wikipedia.org/wiki/Polygonal_modeling

    A polygon mesh of a dolphin In 3D computer graphics , polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygon meshes . Polygonal modeling is well suited to scanline rendering and is therefore the method of choice for real-time computer graphics .
