Changelog

v0.5.1 / 2021-09-08

  • NEW: Added support for textureless colored materials

v0.5.0 / 2021-09-07

  • NEW: Added prelude module. Add use dotrix::prelude::* to include Dotrix, Mut, Const, Context, System and Service to your namespace.

  • NEW: Dotrix::application(...) now includes all core services (Assets, Camera, Frame, Input, Globals, Renderer, Window, World) and appropriate systems in the background.

  • NEW: Added Dotrix::bare(...) function, that initializes empty application, as it was before with Dotrix::application(...). When migrate old code to newer engine version it is recommended to keep using Dotrix::application(...) and remove manually added services and systems.

  • NEW: Added crate dotrix_pbr that can be accessible using dotrix::pbr. It contain everything necessary to perform physically based rendering of solid and skeletal models.

  • NEW: Spawning of PBR entities has been changed, due to refactoring of Model component, that was decomposed into multiple components. Entity representing a solid PBR model requires following components: Model, Material, Transform, Pipeline. Entity representing a skeletal model also requires Pose component.

  • NEW: Added crate dotrix_overlay. Appropriate functionality has been removed from renderer. The new service Overlay has been introduced instead.

/// Show FPS counter
fn ui(overlay: Const<Overlay>, frame: Const<Frame>) {
    let egui_overlay = overlay.get::<Egui>()
        .expect("Egui overlay must be added on startup");

    egui::Area::new("FPS counter")
        .fixed_pos(egui::pos2(16.0, 16.0))
        .show(&egui_overlay.ctx, |ui| {
            ui.colored_label(
                egui::Rgba::from_rgb(255.0, 255.0, 255.0),
                format!("FPS: {:.1}", frame.fps())
            );
        });
}

  • NEW: Added crate dotrix_sky and skybox implementation has been moved there. Refer skybox example code for more details about how to use it.

  • NEW: Added crate dotrix_terrain for height map based terrain rendering. Appropriate example will be added in future releases.

  • NEW: Added engine extensions mechanism. To enable some extra features, like PBR rendering, that may require enabling of several systems and services, it is the easies way to use extensions:

use dotrix::prelude::*;
use dotrix::egui;
use dotrix::pbr;
use dotrix::overlay;

fn main() {
    Dotrix::application("With Extensions")
        .with(pbr::extension)
        .with(overlay::extension)
        .with(egui::extension)
        .run();
}

The following modules provide extension functions: dotrix::{ egui, pbr, sky, terrain }. The order of extensions in application builder does not matter.

  • NEW: The method .with(..) of application constructor can be used to add everything now:
    Dotrix::application("Mighty With")
        .with(pbr::extension)
        .with(System::from(my_system))
        .with(Service::from(MyService::default()))
        .run();

  • NEW: Added Globals service that can store and provide access to global application data. It is useful, when you don't want to have extra services in your app. It is now used to store ProjView, Lights, texture Sampler and terrain Layers.

  • NEW: Multiple Light components has been turned into enumeration of structures to optimize access over ECS.

  • NEW: Added auto detection of a system run level. If system is named after a certain run level, it will be automatically added to it.

  • NEW: Added prioritization of systems. It allows to influence the execution order without dependency on the order of enabling systems in your code.

Dotrix::application("Priorities")
    .with(System::from(execute_last))
    .with(System::from(execute_first).with(Priority::High))
    .run();

  • NEW: Camera service is no longer requires to be set manually. Developer can directly change properties in systems. The engine will do the rest. To initialize camera parameters use startup system.

  • NEW: The biggest change of the release is rendering mechanism. There is no longer a dependency on WGPU code in your rendering systems. Own wrappers has been added instead. It allowed to make Dotrix even more modular and scalable. There is no longer a need to create layout and pipeline separately. Developer can define, what kind of pipeline layout is necessary for specific rendering and Dotrix will create a new pipeline or reuse the previously created.

  • NEW: Dotrix has been completely switched to WGSL shaders.

  • NEW: Added new asset type Shader.

  • FIXED: It is now possible to use custom textures stored in Assets with egui.

  • FIXED: Texture Sampler now solves tiling properly. It is also possible to customize Sampler or even have more Samplers in your code.

  • UPDATE: Egui dependency has been updated to version 0.14.2.

  • UPDATE: WGPU dependency has been updated to version 0.9.0.

  • UPDATE: Winit dependency has been updated to version 0.25.0.
