SgCore 1.4

sgCore solid modeling library is a useful and powerful mathematic engine for you to solve a lot of applied problems. Designed for engineers and programmers dealing with 3D modeling, sgCore meets the majority of requirements in this field and provides high accuracy and modeling speed.
SgCore library is developed by a group of highly-qualified programmers with a profound solid-state modeling experience. Being a base of the SolidGraph CAD system, sgCore is constantly tested and improved according to the geometrical modeling practical needs.
The API simplicity, a great number of functions to create most complicated objects and manipulate them, the small size of the library itself, the full documentation and the 24-hour technical support - all this makes our customers choose the geometrical core sgCore.
Main features:
- creating 2D primitives in the 3D space - points, circles, arcs, splines, contours.
- the basic algorythms for working with 2D objects are: finding the plane where the object is lying, self-intersecting control, finding points of objects intersection, checking the multiplicity of closed objects.
- creating equidistants for 2D objects with various shifts and with a feature of rounding angles.
- creating 3D primitives - spheres, boxs, cones, cylinders, toruses, ellipsoids, spherical bands.
- supports both 3D solids and surfaces
- creating groups of objects
- feature to appoint the users block of data to any object (with further saving of this block in a file)
- calculating of the UV texture coordinates for each polygon vertex using cubic, spherical and cylindric methods of textures mapping.
- 3D polygonal objects triangulation
- flat closed areas with holes triangulation
- Boolean operations with objects - intersection, joining, subtraction
- finding intersection lines of 3D objects
- finding the clips of 3D objects by arbitrary planes
- constructing solids and surfaces of revolution
- constructing solids and surfaces of extrusion an arbitrary flat area with holes along a curve
- constructing spiral solids and surfaces
- constructing solids and surfaces from their clips
- constructing flat faces with holes on boundary contours
- creating solids by surfaces sewing
