Godot Geometry Elements

All examples are created using v2.1.5.stable This repository is dedicated to introducing geometry in game development. For this reason some well known methods of mathematical library of the Godot Engine can be reimplemented in GDScript for purpose of education.

Examples:

Objective of each example is to illustrate how selected geometry topics can be implemented and used in games. Each example have 2 versions (only for porjects in Godot 2.1.5): start with framework for implementation and final containing actual implementation.

2d_steering Godot 2.1.5 version

2d_steering Godot 3.0 version

Introduction to vector manipulation by implementing basic 2d spacecraft steering using simplified Newtonian physics.

projections Godot 2.1.5 version

projections Godot 3.0 version

Implementation of projections. Calculation of object spatial relation.

bezier_curve Godot 2.1.5 version

bezier_curve Godot 3.0 version

Implementation of interactive Bézier curves: linear, quadric and cubic.

targeting_solution Godot 2.1.5 version

targeting_solution Godot 3.0 version

Implementation of two approaches for aiming:

Aim approximation used by manoeuvring rockets

Predictive aim based on quartic equation solution applied to projectiles with constant speed

ray_triangle_intersection Godot 2.1.5 version

ray_triangle_intersection Godot 3.0 version

Implementation of basic ray tracing based on ray triangle intersection algorithm.

selection_in_3d Godot 3.0 version

Implementation of simple method for selecting points in space.
