Publishing Interactive Media on the Web with Playcanvas and Sketchfab
Publishing 3D media and deciding which interactive applications would be the most effective to use can be a long and confusing process. While there are many useful tools bioscience communicators can use to put interactive media on the web, we will be breaking down two of them, Sketchfab and PlayCanvas, and what is required to publish content effectively as an individual or small team.Liza will discuss publishing interactive applications on the browser-based game engine PlayCanvas and using their templates to assist in producing interactive media efficiently. Dani will go over the web application Sketchfab to publish models and animated content. She will also discuss sharing those models in websites and presentations and the limitations of the medium.
PlayCanvas: The audience members will know how to create a simple interactive web app and publish it to the web.
- Navigating the user interface
- Uploading content to the web-based platform and adding functionality
- Utilizing existing templates to produce interactive apps quickly
- Testing out your web creation in browser
Sketchfab: The audience will know how to upload a model and make it viewable to their clients.
- How to optimize models for upload
- How to use their premade materials and lighting system or upload your own textures
- How to import an animated object, create timeline markers, and add labels to a model
- Different options for publishing and sharing work on the platform
Building vasculature in ZBrush
Building realistic vasculature in 3D is a common task for the medical illustrator. ZBrush’s curve brush mode offers some unique capabilities which facilitate construction of complex tubular networks. The tools can be configured to allow the precise placement of vessels at speed and with good control regarding shape and distribution. The presenter will demonstrate how insert mesh brushes can be used to draw vessels onto a surface, adjust placement, taper of vessel, diameter, shape etc. Strategies for managing cut edges and vessel. Bridging, creasing geometry and making models suitable for realtime rendering will be demonstrated and limitations of each discussed. A companion video tutorial will also be made available.
Learning Objectives: Using ZBrush
- To create custom a “Insert Mesh Brush” and use it to build vessels conforming to an underlying model in
- To modify a stroke (nudge, elongate, taper and crease.)
- To save custom brushes and settings for future use.
Keywords for Presentation: ZBrush, modeling, realtime rendering

Visual inspection of PDB models
The main purpose of the workshop will get familiar with the software PyMOL. This is one of the standard molecular visualization system software used in academia and research labs. Its functionalities include common representations for macromolecular structures, inspection of electron density maps, molecular editing and calculation of other structural parameters of PDB models. It is a very powerful software that can used both via a graphical user interface or in a command line mode, making it very versatile for audiences with different needs and skills.
Learning Objectives: After the workshop, participants will be able to open PDB structures directly from the database and visually inspect them using the software PyMOL. Based on the their personal interest, attendees will be able to calculate and examine structural features of proteins such as distances between atoms, cavities, electrostatic potential surfaces, and the effect of single point mutations among other properties
Keywords for Presentation: structural biology, protein inspection
Maya 2020 Spline IK for Modeling and Animation
After viewing this presentation the learner will be able to construct a Spline IK (inverse kinetics) Handle using the animation-key menu in Maya 2020. This showcase will demonstrate how to use a spline IK to model and animate an endoscope, as well associated instruments. In addition, the showcase will present techniques for employing a spline IK to create the curvature of the vertebral column and the large intestines.
After viewing this showcase the learner will be able to
- animate an “endoscope” as it inspects an environment.
- model the “natural” curvature of an anatomic structure or organ.

Pen & Ink, Nib to Paper
During a 30 minute presentation information about the history of Pen and Ink will be discussed, different types of nibs and variety of uses will be demonstrated. Difference of papers and difference of ink types. Scanning and clean up of traditional media will be discussed. Briefly introduce history of pen and ink and examples of flexible nib pen and ink from medical and non-medical illustrators.
Learning Objectives: Individuals participating in the ZOOM demonstration will be able to identify: Different types of nibs and understand their strength and weakness Different types of papersIndividuals should be able to select nibs and pen holders and experiment which options work best for them.Individuals should be able to discuss options for scanning final P&I artwork, what softwares help to optimize best digital file for print production. Individuals should be able to describe a “moire effect” in pen and ink. When it can be beneficial and when it can be distracting. Individuals will be able to identify different medical illustrators by pen and ink style.
Traditional Carbon Dust on Coated Illustration Board
This talk will cover the history of carbon dust illustration from its roots in 19th century European fine art to the use of this medium in both 20th and 21st century medical and scientific publications. The traditional technique of carbon dust will also be covered in this talk including the use of drawing tools, illustration boards, and papers. A recorded video demonstration will document the technique from start to finish. A live virtual event will allow for questions and answers as well as a discussion of the relevant history. Closing the talk will be a look at how carbon dust is still a viable illustration technique when combined with Photoshop.
At the conclusion of this workshop the student should:
- Identify and use drawing tools to create a carbon dust illustration
- Identify illustration boards suitable for carbon dust illustration
- Appreciate the history of the carbon dust medium and why it is still used in modern publications

Maya will demonstrate some loose and abstract acrylic painting techniques from my studio. Participants may watch or follow along with their own supplies. We will be taking a break from the accurate, tight, illustrative quality of our usual work. The loose application can help us to move our bodies, play with color and layering, and create textures which are not entirely planned out. Alongside the pure fun and fine-art making possibilities, these textures and abstractions can be useful later in our medical illustrations – on a Photoshop layer or 3D material. Optional materials: canvas, acrylic paint (heavy body or fluid), brushes, water
Learning Objectives: At the conclusion of this demo, participants will be able to choose acrylic painting materials, apply paint to canvas, layer transparent paint, and use water to make drips on the canvas.
Keywords for Presentation: painting, fine art
Photogrammetry for surgery
Capturing a photography-based 3D snapshot of an intraoperative surgical field has tremendous educational potential. The logistical limitations of a live operation and sterile field produce unique challenges–a single camera cannot compensate for the inherent movement of living human anatomy, and existing multi-camera rigs are too large and expensive to be practical in the OR. We are currently developing and testing novel approaches to address these challenges.
Learning Objectives: After participating in this session, attendees will be ready to apply the fundamentals of the photogrammetry reconstruction process from initial photo capture to production-ready 3D model assets for animation or VR. Best practices for photographic capture to be used in photogrammetry will be discussed, as well as recommended settings for organic subjects in photogrammetry 3D software reconstruction, and methods of refinement of 3D models to be used for animation or interactive applications.
