# Transformation Cube Shader 

## Overview

Transformation Cube Shader is a Unity project that applies transformation effects—scaling, rotation, and colour manipulation—to a 3D grid of cubes in real-time. It showcases dynamic transformations controlled programmatically and through user input, creating a visually striking effect that leverages HDRP's high-quality rendering features.

## Features

### High Definition Render Pipeline (HDRP), URP and build in Compatibility

* Designed for Unity's HDRP, enabling advanced lighting, shadows, and post-processing effects for high-fidelity visuals.

* Also compatible with URP and build in pipeline -> Can run on touch-enabled devices



### Dynamic Grid Setup

* Generates a grid of cubes at runtime based on the specified gridResolution parameter.

* Each cube has unique properties and transformations, offering a high degree of visual customisation.



### Real-Time Transformation

* Scaling: The entire grid and individual cubes scale dynamically over time, creating a pulsating effect.

* Rotation: Continuous rotation is applied to the grid with individual cube adjustments.

* Colour Shifts: Dynamic colour changes across the RGB spectrum, creating a vibrant animation.



### Interactive Controls

* Mouse Control: Enables rotation along with mouse input on the screen.

* Touch Control: Supports single-touch rotation and multi-touch (pinch) scaling on touch-enabled devices. (This only works for non HDRP projects)



## Scripts

* `TransformationGrid.cs`



  This script handles:



  * Grid Creation: Instantiates cubes in a 3D grid with gridResolution settings.

  * Transformation Pipeline: Manages scaling, rotation, and position transformations across the entire grid using Transformation components.

  * Colour Updates: Adjusts the colour of each cube based on its position and time to create a shifting visual effect.



* `MouseInput.cs`

  This script enables user interaction:

  

  * Rotation Control: Rotates the cube with mouse movement along X and Y axes.

  * Touch Scaling: Allows for pinch-to-scale gestures on touch-enabled devices. (Only works for non HDRP project)

  

## Installation and Usage

* Clone the Repository: Download or clone this repository to your local machine.

* Open in Unity HDRP for better visual effect: Open the project in Unity Editor with HDRP enabled (Unity version compatible with HDRP).

    * Or open in URP/build in pipeline for touch-enable devices control

* Configure parameters such as gridResolution, rotationSpeed, scaleSpeed and assign prefab in the TransformationGrid component to spawn your desired gameobject 

* Run: Play the scene in Unity to see the grid transformation in action.

    * Control the cube rotation using mouse input/Input touch in the game view at run time



## Dependencies

* Unity Engine with HDRP enabled (Unity version compatible with HDRP)

* No additional plugins are required.
