Camera 3D

Similar to 2D rendering, which needs Camera2dBundle, 3D rendering needs Camera3dBundle in order to show any 3D objects.

use bevy::{
    app::{App, Startup},
    core_pipeline::core_3d::Camera3dBundle,
    ecs::system::Commands,
    DefaultPlugins,
};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_systems(Startup, setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn(Camera3dBundle::default());
}

In default, the camera is at the position (0, 0, 0). The 3D space is consisted of the x-axis, y-axis and z-axis. Positive x points to right. Positive y points to up. And positive z points out of the screen, toward us.
