We began FLAME by learning the basics of 3D modelling using Blender. Complex shapes can be broken down into basic primitive shapes. Paul is interested in recreating the built environment around us including a local skate park. Here he has recreated O'Reilly Hall.
You can also use a free add-on for Blender to download Google Earth 3D tiles and let it do a lot of the work for you. The 3D map of Belfield was imported and a video was created with a flyover of the campus. The 3D models are not of particularly high quality when viewed up close but offer a quick way to build a large scene. Combinng this data with carefully modelled buildings gives the best result.
Shauna worked on a rigged model of a cat to demonstrate positioning during radiography. This involved applying a skeletal rig to a 3D model of a cat and using inverse kinematics to realistically control limb response. Students can view the animation from any orientation to get a better understanding of how to perform an X-ray correctly.
The environment is a 360 degree image of a surgical theatre created by Oliksiy Yakovlyev under a CC0 license and is available here. This can be used to ground a 3D model in a representative environment.
Richard is studying to become a teacher focusing on maths, science and physics. This demo illustrates the effect of capacitance, plate overlap area and the resulting change in the behaviour of the gold leaf electroscope. This type of animation can be used to prepare students for what they will observe in an upcoming experiment or to offer an experience not physically available to them.
This wheel is based on examples from two Roman sites in northern Britain. It has two distinct features - a particular type of spoke manufacture that seems to be unique to this period. These are turned on a lathe and have a characteristic double step tenon where the spoke fits into the hub. The second feature is a felloe (wooden outer rim) that is made from a single piece of wood. An iron tyre would probably have fitted over this (not yet modelled!) Often we only find parts of objects like these surviving so a 3D representation that can be taken apart helps students to understand how we visualise a complete object from individual parts found in different locations.
Lauren is a visiting student working with Dr Nigel Kent from DCU. They are interesting in developing visualisation of the operating principles of a DC motor from a solid model to exploded view to interaction between current flow and magnetic field resulting in torque. Lauren has created her own page to demonstrate her work HERE.
Like Lauren and Nigel, Paul is interested in demonstrating how motors and other electronics work. Paul leveraged his learnings from the workshop to deploy a 3D model using the SketchFab platform embedded in BrightSpace. This commercial tool offers an alternative to Model-Viewer making the process of embedding 3D content easy.
Donal teaches a core Engineering module where students learn about mechanical systems such as linkages, gears and motors. Using Blender's rigid body physics tools he has created several of these systems.
Cathy works to build realistic and authentic simulations for medical training In this case a model of the tracheostomy tube was created and paired with a commercially available 3D model of a syringe. The texture on the syringe was updated using Blender and Photoshop to replace the gradations to match that used in real procedures. This is case the animation was rendered to video using the cycles renderer which uses path tracing for photorealistic light transport. The result is that the use of alpha channel textures and physically based materials generates a video that is very life like.
Allison teaches the fundamental principles of the operation of Magnetic resonance imaging. This animation illustrates the effect of a magnetic field on the behaviour of a proton as it undergoes Larmor precession. Like Cathy, Allison presents her work as a video. However, here she has chosen to use the Eevee renderer due to its speed. There is little need for photorealism in such a demonstration and since this animation renders in near realtime Eevee is a good choice. Procedural textures are applied to the particles so that their rotation is clearly visible.
Mugesh expressed an interest in bringing many of the statues and sculptures around us to life. Here we see the Black Tulip piece by Eamonn Ceannt located just outside the O'Brien Centre for Science. Mugesh used a smartphone 3D scanning app to capture the shape of the sculpture which was then imported into Blender. An armature using inverse kinematics is used to deform the geometry.
Here Mark is exploring different materials and textures to generate compelling visualisations of cells. 3D models displayed on webpages such as this have limitations in terms of file size and rendering techniques, transparent materials in particular require sophisticated shading methods. The video below is path traced and we see the complex refraction of the light throught the transparent medium. This is lost in the 3D model. The educator needs to decide which approach suits their teaching.
Here rigid body physics and rigid body constrainsts such as hinges, sliders and springs are used to simulate a vehicle traversing a complex terrain. Dynamic paint is used to capture tracks left by the wheels on the ground. Simulations like this run quickly using simplified physics solvers and allow students to interact with concepts such as Hooke's law in an engaging way.
Martin developed several examples of interactive anatomical models and expanded the interactivity within Brightspace using the Verge3D plugin. This exports web and SCORM content compatible with Brightspace and adds extra functionality to control the model in the browser, with drag’n’drop coding. Martin also used the hotspot feature in Model-Viewer to add labels to 3D anatomical models.
Here is an example showing an interactive exploded view of a CAD model. The animation can be interrupted using a slider.
