ISO 10303 - is an ISO standard for the computer interpretable representation and exchange of industrial product data. Engineering drawing (the activity) produces engineering drawings (the documents). It uses a symbolic language on engineering drawings and computer generated three dimensional solid models for explicitly describing nominal geometry and its allowable… … WikipediaĮngineering drawing - Technical drawings An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items. Geometric dimensioning and tolerancing - (GD T) is a system for defining and communicating engineering tolerances. Our Matrix classes have standard matrix operations like Multiplication, Inverse, Rotation, Scaling, and Transformation etc.Смотреть что такое "geometric dimensioning and tolerancing" в других словарях: Alternatively, a generic Matrix class can be created and 2D and 3D Matrix classes can be derived from the generic class. I have created specific Matrix classes for 2D and 3D for convenience. You can find more information by searching on the web.
We use a 3x3 matrix for 2D and 4x4 matrix for 3D. This also allows transformations to be concatenated easily by multiplying their matrices - from Wikipedia. Matrices allow arbitrary linear transformations to be represented in a consistent format, suitable for computation. Our Vector classes have standard vector operations like Addition, Subtraction, Transformation, Negation, Dot Product, Cross Product, finding the angle between two Vectors etc. The Vector does not have a fixed location in space. The Vector has two properties: Length and Direction. VectorĪ geometrical Vector specifies the direction in space.
A Point is represented by its X and Y (also Z in the case of a 3D point) coordinates. PointĪ Point represents a two dimensional or three dimensional point in space. You can get more detailed explanations about Geometry, Vector and Matrix functionalities by searching on the web. The 2D classes are used for two-dimensional geometry, and 3D classes for three-dimensional geometry. I have created 2D and 3D classes for each of these ( Vector2D, Vector3D, Matrix2D, Matrix3D, Point2D and Point3D).
This geometry library contains only some basic classes like Vector, Matrix, and Point. It also has options to view the 3D object along different axes. The test application reads a point data file and draws lines connecting the read points. A test application also has been developed to test this library. I have created a 3D geometry library with just the basic classes like Vector, Matrix, and Point. I am not using DirectX or any other library. The list of points is generated by some other software. I had a requirement to plot a list of 3D points on a graphics display.
