Dotrix

3D Game Engine written in Rust (development stage)

Overview

Dotrix has a flat linear ECS (Entity Component System) in its core, designed for fast querying of entities and their components.

1. Entities in Dotrix are virtual abstractions, identified by EntityId component containing numerical ID. Each entitiy agregates constant number of components.
2. Components are regular Rust structures.
3. Systems are Rust functions, implementing the core logic of a game.
4. Services are Rust objects available through systems, providing some key features or access to global resources, like Assets, Input or Render management.

Editor

Editor application is under active development in the separate repository lowenware/dotrix-editor.

Getting started

The best place to start is to review examples distributed with the engine. All examples are grouped under examples/ folder. Later when API becomes more or less stable we will prepare a Book for a quick start.

Demo Example

cargo run --release --example demo

EGUI

cargo run --release --example egui

Skeletal Animation

cargo run --release --example fox

SkyBox

cargo run --release --example skybox

Shaders Compilation

Migration to WGLS shaders is pending

Dotrix is distributed with both sources and precompiled to SPIR-V shaders. So until you make a change in a shader's code, you won't need to compile it. We are looking forward integration with naga, but until it is not ready, there are two possibilities of how to deal with shaders.

Using glslang

You can compile GLSL shaders into SPIR-V using glslang. This is the way how we compile them for releases.

Using shaderc

You can also compile shaders at a runtime, which is very helpful during development using optional shaderc feature. To make it working, you will need a recent version of shaderc library which can be built using cargo or obtained as a part of the Vulkan SDK.

Once you have it, don't forget to enable the feature during compilation:

cargo run --release --features shaderc --example demo
