Introduction

What's HeadAtlas:

An educational game for studying neuroanatomical details on mobile devices with Augmented Reality

You can access more than 2500 labels and descriptions and use 3 different visualization tools: create sections, isolate objects, exploded view.


Head Atlas provides a variety of texts organised into three cognitive levels, from general overviews to highly specific definitions, to facilitate learning and memorisation.



What I've done in this project:

UI/UX, Augmented Reality, Scene Setup with complex 3D organization, All methods and functions, In-Depth Code optimization, Database, Online Server API, Camera Behaviours, Input, Object Selection through shader (Not Colliders due to optimization needs), Section Shaders, Recolor and retexturing Shaders, Services (Savings, In App Purchase, News, Store)

Selection without Colliders or Raycasts

Pixel Shaders

Due to optimization needs (we had more than 3 Milions vertices), we decided to remove all colliders from our 3D objects in the scenes. This solution leads to a major performance improvement but it creates another problem: Raycast to select an object is now unavaible.

To solve this problem I used a render texture applied on a Plane that mirrors the rendered screen but, instead of using the normal object material, I used a UNIQUE randomly generated RGB color code applied to every single interactable's object shader. (See video) After that, we can easly check, given the user's input position, the same position on the renderPlane and get the precise color of the selected pixel. Given the fact that every color is Object-unique, we can easly return the selected object without using any raycasts or colliders.

Section

Pixel and Vertex Shader

This shader uses an hidden plane that moves around the scene following the user's input in order to gather his world position.

Every pixel of the meshes then make a check between its relative position and the forward vector of the plane.

If the check fails, the pixel will be discarded during the rendering queue and will not be rendered

That's how I managed to achieve a section effect of a complex mesh

Augmented Reality

using ARFoundation (ARCore/ARKit)

The big challenge was to design every functions and aspect of the application to make it works both on a regular session and on a stable Augmented Reality Session.


This app uses the Plane Detection features from ARKit & ARcore that allows the user to place the 3D scene on an Horizontal plane

Technologies: ARKit ARCore

Features: Plane Detection

Introduction

What it is

Neurosurgery is a comprehensive library of modules for mental training. It contains 3D tools for Augmented Reality designed to improve 3D surgical knowledge and enhance the training experience in a revolutionary way. It also contains a real time stream of updates from the scientific community. Modules available: Craniotomies light/full Craniotomies is a powerful tool for 3D mental skill augmentation with a particular focus on neurosurgical approaches. This module, available in a light and a full version, is designed as a virtual simulation sequence of mental training steps: Planning, positioning, step-by-step approach, microscope, closure.

In the full version all the approaches are explorable in augmented reality and the scene has a full-screen mode for amazing screenshots that you can use for your classes or daily notes!

Sequence of scene from the App

Those are some steps that you can do inside the app, every choice you made is significant for the next scenes.

  • Planning your craniotomy
  • Position the patient accordingly to the choosen craniotomy
  • See the complete animation for that approach
  • Using the Gyroscope, simulate a microscope exploration

    The achievement here is being able to see patient's positiong in Augmented Reality and use all the head positioning functions provided by the app

    Mesh Deform

    Vertex Shader

    For this shader to work, I have used two meshes; the first one is the brain with his normal size and the second one is the same brain but completely deformed


    Following the user's input I am able to evaluate which vertices had to be deformed and then interpolate between the original position of the vertex and the same vertex position of the completely deformed mesh

    I've decided to use this strategy because, during real surgery, we cannot deform a brain completely but we have some sort of threshold.
