Overview

3D Rendering and physics in vanilla C#, no OpenGL or any other libraries.

• Made to be very simple to use
• Comes with some primitives but also supports loading OBJ files
• Dynamic objects / static objects supported (collision detection uses GJK)

Examples:

Utah teapot

Explosion of cubes and spheres

Code to generate the explosion

Basic Usage

Getting started:

1. Create a class that inherits from Engine
2. Create a constructor that takes in a Size and string
3. Override the Awake and Update methods
4. In Program.cs or wherever your Main method is, create a variable of type Engine and set it equal to the new class you've created
5. Call .Run() on the variable

Update and Awake overrides:

Awake is run first as soon as the program begins, and Update is run every frame after that.

GameObjects:

Adding and removing objects:

GameObjects are added by using the Instantiate method, parameters being the GameObject to add and the ID of the GameObject. IDs are provided as a way to keep track of each GameObject and have the ability to change/delete individual objects after creation. To delete an object simply call the Delete method and pass in the ID of the object as the only parameter.

GameObject class:

The GameObject class contains information about the Position and Rotation (both stored in Transform), Mass, Force, Velocity, Color, Mesh, and whether or not the GameObject is Dynamic.

The Step method:

The Step method is used to calculate the physics on individual GameObjects, and is virtual so it can be overrode to provide custom physics to each object.
