Google Poly: Low Poly Alternatives

We learned recently that Google Poly would be closing as of June 30, 2021. Uploads will be turned off April 30. As a 3D creation and viewer tool, students and educators are easily able to create low-poly objects with in-VR tools and share them with others, expanding the range of 3D objects available for education.

Many artists, creators, educators, researchers, developers, and historians have uploaded “irreplaceable” cultural artifacts to the service and consider it to be a “cultural museum” of 3D and VR history. They are demanding the archive be preserved and continue to be curated in some way. A petition on is inviting signatures to encourage Google to open source the Poly platform. We encourage you to join.

Photogrammetry Examples and Resources

Mark Jeffcock presented a workshop in AltspaceVR on photogrammetry recently, inspiring others to step into photogrammetry.

Among the many tips and tricks Mark offered during the workshop, he emphasized taking as many photographs as possible from multiple positions and heights. It’s not about photographing around the diameter. The 3D images need to capture over, under, and inside. The software then stitches the images together to created the final 3D image.

He’s encouraging people to create their own photogrammetry project and share it on our Educators in VR Discord group in the Weekly Discussion channel. You may share a link to the Sketchfab asset or, if you import it into AltspaceVR or another social VR platform, a link to your publicly accessible virtual world. We’d love some show and tell of your great creative works.

The video of his presentation in AltspaceVR for Educators in VR is on our Educators in VR YouTube channel.

Mark mentioned that most of the photogrammetry software is designed for the real estate industry, agents and homeowners with little or no technical ability, which makes it ideal for student and class work.

Other services mentioned to help you create your own 3D models with photogrammetry included:

  • 3Dflow/3DF Zephyr: 3D Flow is a commercial company offering solutions and software for photogrammetry, 3D modeling, processing, and visual effects. Their product, 3DF Zephyr is available for free and paid versions to process images for photogrammetery. The free version is limited to 50 images per project, enough to learn about how the process works and create small objects good for use in AltspaceVR and other low poly social VR platforms with world building.
  • MicMac: A free, open-source photogrammetry suite used to create 3D reconstruction scenes, models, and othro-imagery.
  • COLMAP: A general-purpose Structure-From-Motion (SfM) and Multi-View Stereo (MVS) pipeline with a graphical and command-line interface to reconstruct ordered and unordered image collections for 3D renderings. Instructables has a simple guide for installing and using COLMAP.
  • Credit and monthly fee photogrammetry software for scanning, creating, and sharing 3D scenes and assets including full-body scans, 2D and 3D maps, and 3D printing.

Cyberbullying Month: Resources and Research

Educators in VR is recognizing Cyberbullying Month all October. We have three events lined up for you. Tuesday, October 15, is Daniel Dyboski-Bryant and special guest Lucas Rizzotto, award-winning director and pioneering VR and AR storyteller, developer of “Where Thoughts Go,” the successful virtual storytelling creation app. They will be discussing using empathy in VR to build awareness and sensitivity training for educators and learners, and beyond. On Tuesday, October 29, Educators in VR will be presenting a special program to conclude Cyberbullying Month, and Thursday, October 17, is a special Cyberbullying Panel Discussion hosted by veteran Virtual Communities Consultant, John Williams (JayW) and representatives of the AltspaceVR Staff and Community including special guest Keegan Law, the Program Owner of AltspaceVR. We will be discussing and sharing insights on cyberbullying in virtual reality.

John Williams and Lorelle VanFossen gathered information and resources for you in support of Cyberbullying Month.

Virtual harassment and bullying isn’t new. Julia K. Ferganchick-Neufang published “Virtual Harassment: Women and Online Education” in February 1998, tackling the issue of student aggression toward female instructors online even before Second Life was launched in 2003.

The “virtual” aspect of virtual reality creates a distance that makes it easy for us to ignore the very real human communication and interaction of such spaces. If we are to challenge these abusive attacks from students and the passive-acceptance of this behavior from administrators, we need to work collectively to convince others, including program administrators, to take us seriously. Student aggression, whether it takes place in writing, in person, or online, is a violation that creates a hostile or intimidating work environment; it is harassment and must be treated as such.

…I do not believe that virtual space is either evil or inherently masculine and patriarchal. What bother me is not the medium, but the lack of attention paid to how that medium may perpetuate sexism and violence against women. I agree with Lari Kendall who says, “the online environment is not itself a solution. Understandings of gender and the hierarchical arrangements based on these understandings do not simply disappear in forums where we can’t see each other. We carry these understandings with us and re-create them online. Therefore, the appearance of more women on MUDs, and online generally, is likely to help only if both women and men make specific efforts to counter…stereotypical understandings.”

This article highlights the negative side of virtual reality, but know that it is statistically a low risk. Depending upon the game or the social VR app, community standards, moderators, and the community itself tends to self-police in a way that represents their goals for the community.

AltspaceVR, for example, is one of the oldest immersive social VR platforms, and has a multi-prong approach to community standards and violations. Their terms of service and AltspaceVR’s Community Standards were designed with community in mind. Not that people read them when creating an account, but the community standards are reinforced by the AltspaceVR 101 30-minute tutorial recommended to newcomers, and through the volunteer Community Helper program of experienced community members helping other members through positive example and mentorship and supportive events. They are aided by the Community Support Team members in the campfire “lobby” to ensure a tolerant and inclusive community.

To begin our dive into cyberbullying and virtual reality, let’s begin with the example of the Community Standards by AltspaceVR as it is an example to other social VR platforms and games, and may serve as a good example for VR in your classroom and school.

Defamation and Intolerance

AltspaceVR is an international community of users that come from many different cultural backgrounds. Each community member has their own individual background, cultural practices, accents and mannerisms, belief structure and reasons for being in VR. As a community that is enriched by this multi-cultural environment, there will be no tolerance for bigotry regarding any user’s race, nationality, spiritual beliefs, physical abilities or sexual orientation. Any language that is meant to defame or injure another user will result in an immediate suspension and determination as to whether the account will be closed permanently.


A healthy community is rooted in the shared understanding that everyone is entitled to feel and express whether something is offensive or uncomfortable for them. When a user chooses to ignore this and continue to aim the uncomfortable behavior at that person, it is perceived as Harassment. If another community member expresses that something makes them uncomfortable, it is your responsibility to cease that behavior in the presence of them. Continued harassing behavior will result in a suspension and subsequent determination as to whether the account will be closed permanently.

Cyber-Bullying and Intimidation

While Cyber-Bullying is regarded as being an issue affecting teens and pre-teens, we are including it as part of the Community Standards so that we make it clear that any form of intimidation levied against another user be it on the AltspaceVR platform or on any social media or forum site managed by Microsoft, shall be considered grounds for suspension or account termination.

As with all such documents, it is a living document, shifting and changing as the needs of the virtual community’s needs change.

Here are some other examples of terms of service and community policies for social VR platforms.

Behind Every Avatar is a Real Person

Behind the cartoon avatar, it’s easy to forget that you are standing with real people with real emotions, sensitivities, anxieties, history and experiences.

The avatars are just masks, malleable, easily changed, sporting a robot or human-style presentation customizable to anything including green skin, red hair, purple eyes, and black shirt and pants with green shoes. Gender, sexual preference, personal characteristics disappear behind these avatars, or are enhanced by choice to represent the real person or their creative spirit or life choices. Just as in the real world, bullying over skin color, disfigurements, tattoos, and any physical differences is unacceptable. Even with limitations in avatar construction, people’s appearance choices are to be honored and respected.

Virtual reality allows you to be you without physical insecurities getting in the way. Avatars may become extensions of the users, their mind and heart embodied. Such fragile selves need protection in VR and the real world to be allowed to explore, develop relationships, and blossom. Continue reading

VR Permission and Waiver Forms

Young girl looks up wearing VR headset.Exploring the world in virtual reality means no field trip permission slips, no travel logistics, and lightens the financial and liability load on an educational institution, but we still can’t escape all permission slips and waivers. Lately, there have been requests and discussions in our Educators in VR Discord server about Virtual Reality Waivers and Permission Forms for underage students and the general public to be used in schools, libraries, and for public demonstration events. We went digging and found there are some good examples online.

Each public or student use of virtual devices varies per usage, device, physical setting (VR lab versus a chair in a library), student limitations, facility limitations, event or class outcomes, number of participants, etc. The permission and waiver should represent the specifics of the situation as well as the needs of your institution and facilities. Use the examples below to help you write your proposed waivers and review them with your administrators and legal representatives.

Let’s review the details that make a virtual reality waiver and permission form distinctive from other parental and guardian approval forms for students and for general use of VR in libraries and other public facilities.

Privacy and Age Restrictions

Privacy is a big issue for all online activities and apps, and VR is no exception.

Any information disclosed through registrations or interactions online through software, apps, or online access come under several international privacy laws. The EU GDPR and other privacy laws, with which most of the world complies, applies to children under the age of 13. In general, under 13 should not access most Oculus VR, PlayStation, Steam, and other VR stores, and social VR apps like AltspaceVR, VR Chat, etc. Individually, countries and states have various age restrictions in general ranging from 12-16. The form should comply with your local laws as well as your institution’s requirements so users agree to abide by the privacy policy. Be aware that individual virtual apps also have age restrictions of their own, including age usage recommendations.

While it is beyond the scope of this informational article to discuss the pros and cons of such age law restrictions, be aware that there are many VR apps and games designs for under 13. These are not social or multi-player but individual, one-person experiences. Library and educational institutions preinstall apps for students and user access, controlling access and restricting usage to age-appropriate content, often clarified in the waiver.
