Introduction:

Using Unity Web and our own frameworks, we have created many easily accessible 3D models to aid students in their studies across BCIT. The applications employ simple mouse controls to pan and zoom the models and click and drag parts, and employ UI toggles for users to explore specific parts of the 3D model.

These are a few examples of applications integrated extensively in BCIT’s course curriculum for the School of Health Sciences (SoHS) and School of Transportation (SoT).

BCIT SoHS Unity Web Aorta and Great Vessels

This model, along with the others, shows several key parts of the human body in relation to the skeleton, which helps students to better understand anatomy in relation to what they see on MRI scans.

Students can zoom, pan and rotate around each model, and can separate several parts to get a better look at the organ and view further inside the body.

Each model has 3D labels for the most relevant sections of the body. As well, each part that can be separated has a tooltip that identifies the part while the user hovers over it.

BCIT SOHS Brain Anatomy

This model is integrated in multiple SoHS programs, especially in Medical Radiography and Diagnostic Medical Sonography. It lets students view the brain’s anatomy and all the veins and arteries connected to it.

Students can view specific anatomy, veins and arteries by dragging parts out and zooming in. Moreover, students can make specific parts transparent for better visibility and a more detailed view.

BCIT SOHS Unity Web Carotid Artery

This model is used extensively across the SoHS, especially in the Diagnostic Medical Sonography program. It allows students to pan around a model of a human, with layers showing different anatomical systems.

Users can rotate with the right mouse button, zoom with the scroll wheel, and pan with the arrow keys/WASD.
The model includes a manipulatable ultrasound transducer to display ultrasound images across different parts of the carotid artery.

BCIT SOT Unity Web Transmission

This Unity Web transmission application is an essential part of the School of Transportation’s automotive service educational program (ASEP).

The 3D assets of this particular transmission were custom-developed with the collaboration of instructors in the ASEP program.

Students can view the transmission module in normal mode and transparent mode (“isolate”). Transparent mode allows the student to see through the transmission and select specific parts to view while the transmission is still intact. Moreover, students can disassemble the transmission by using the mouse pointer to drag away almost all the components.

BCIT SOT Unity VR Railway

In 2019, 1246 rail accidents were reported to the Transport Safety Board of Canada (TSB), up from the 2018 total of 1169, and an increase of 17 from the previous 10-year (2009–2018) average of 1064. Among all railway accidents reported to the TSB in 2019, 169 involved dangerous goods (reference from https://www.bst-tsb.gc.ca/eng/rail/index.html).

This standalone VR application simulates an accident scene involving a railway train that contains UN 1017 transport goods. The code UN 1017 stands for chlorine, a dangerous good.

The purpose of this VR application is to increase the awareness of railway knowledge. Furthermore, the next iteration of this application will simulate how the emergency medical responder in the area will respond to this kind of incident.

BCIT SOHS Unity VR Be the Beam

The Be the Beam project won the 2019 Simulation Canada Innovator Award

Be the Beam is a guided VR experience that takes the user through the process of x-ray production while focusing on the physics behind the process. The goal of Be the Beam is to use the visualization power of virtual reality to strengthen students understanding of x-ray physics as it relates to their work in the Medical Radiography program at BCIT.

After exploring a modern x-ray room, users will shrink down and enter the x-ray equipment to explore the process of x-ray generation. The seconds required to take an x-ray are expanded into several minutes, as the user watches electrons fire from the cathode at high velocity towards the tungsten- and rhenium-plated anode where they are converted into x-rays. The VR user then follows the path of x-rays through collimation, into the patient’s abdomen, and finally to the digital x-ray receptor located inside the x-ray table. Along the way, the physics of the entire process is explained. Be the Beam is complemented by learning modules outside of VR that are provided to users both before and after the VR simulation.
