Lego Constructor

BMSTU IU7, semester 5 — computer graphics coursework.

A 3D Lego-style building editor in Qt with its own software renderer: no OpenGL, the whole pipeline — projection, rasterisation, shadow mapping — is written by hand.

Structure

Path	Contents
lego-course-work/renderer.*	Rendering pipeline
lego-course-work/shadow_map.*	Shadow mapping
lego-course-work/scene3d.*	Scene, camera, interaction
lego-course-work/grid_system.h	Build grid with distance-based fade
lego-course-work/model.*	Model and its serialisation
lego-course-work/*element.h, brick*, plate*, rooftile.h	Part types
lego-course-work/selection_manager.h	Selecting and moving placed parts
lego-course-work/demo*	Demo recording and playback
lego-course-work/tests	Tests

Parts snap to a grid; models are saved and reloaded through model_serializer, and a demo mode records a build session and replays it.
