UGizmo

Highly efficient gizmo drawer for Unity.

UGizmo-02

Overview

UGizmo is a library that adds various features to the standard Gizmos class and allows calls at runtime and the Unity event functions. Also, by using GPU instancing to reduce draw calls, you can draw gizmos efficiently.

Key features

Available to be called by event functions such as Update(), LateUpdate(), etc.
Runtime support
Draw call optimization using GPU instancing
More than 30 gizmos

Draw call optimization

Getting Started

Requirements

Unity 2021.3 or higher
URP or HDRP (Built-in Render Pipeline is not supported)

Installation

You can enter the following link in the Package Manager of Unity

https://github.com/harumas/UGizmo.git?path=src/UGizmo/Assets/UGizmo

or open Packages/manifest.json and add the following to the dependencies block

{
    "dependencies": {
        "com.harumaro.ugizmo": "https://github.com/harumas/UGizmo.git?path=src/UGizmo/Assets/UGizmo"
    }
}

Samples

It can be drawn by using the UGizmos class.
In the standard Gizmos class, the matrix is specified using Gizmos.matrix, but in UGizmo, the position, rotation, and scale information is passed as method arguments. Also, the color should not be specified using Gizmos.color, but directly passing the Color structure as the method argument.

using UnityEngine;

public class DrawCubeSample : MonoBehaviour
{
    private void OnDrawGizmos()
    {
        UGizmos.DrawCube(Vector3.zero, Quaternion.Euler(45f, 45f, 45f), Vector3.one, Color.red);
    }
}

Open Package Manager > UGizmo > Samples to install samples for URP and HDRP.
