Construct-IT is a CAD system for modeling, calculating, and validating of scaffolding assemblies.I have designed and implemented from scratch a 3D engine for WYSIWYG module for preview of scaffolding assemblies (including buildings and landscape), with real-looking scaffold elements, possibility of rotating and moving to view from any angle and with any zoom etc. The engine was written on Delphi directly connecting with DirectX Direct3D API for 3D acceleration. Refactored old 2D design and edit modules for using capabilities of DirectX.Later on, I participated in refactoring and optimization of business logic of the project, analysing and designing of new functionality.I have implemented complex geometrical algorithms for dynamic 3D generation and visualization. Have done rendering optimization. Implemented miscellaneous mathematical algorithms (to calculate optimal solutions and load limits etc.) Designed 3D models in 3ds Max. Participated in designing, developing and maintaining of business logic. Mentored junior developers.Used tools: Delphi 7, DirectX, 3ds Max, OOP/OOD, Math, Borland StarTeam, Ms SQL Server.
