As part of an exploratory grant project for Landscape Construction, Materials, Methods and Documentation (LAR 457), <\/span>Postdoctoral Research Scholar <\/span>Muntazar Monsur<\/span><\/a> and <\/span>Teaching Assistant Professor <\/span>Carla Delcambre<\/span><\/a> from the <\/span>College of Design<\/span><\/a> are working with a team of dedicated DELTA staff members to create an immersive, 3D environment that students can explore using virtual reality (VR) headsets. <\/span><\/p>\n

The main deliverable of this project is an immersive, 3D environment built in the <\/span>Unity Engine<\/span><\/a> that can be explored using a VR headset. Embedded in the 3D environment will be several short videos demonstrating the building process at different sites such as the Syme Hall rain garden and construction at the Avent Ferry Complex that is still ongoing. There will also be a WordPress site hosting a browser version of the environment and a collection of resources, such as case studies, models and drawings of past projects. The project will be fully deployed by September 2018.<\/span><\/p>\n

Delcambre has been teaching LAR 457, a five-week summer course, for more than seven years. The purpose of this course is to help students understand various landscape architectural concepts, such as the application and use of sustainable materials, green infrastructure techniques and commonalities between abstract design and physical realities. <\/span><\/p>\n

Monsur and Delcambre began working together as part of the College of Design\u2019s <\/span>Natural Learning Initiative<\/span><\/a> (NLI) team. They were inspired by the capabilities of VR technology to enhance student learning after seeing the success of other DELTA grant projects, including Monsur\u2019s work with Research Associate Professor <\/span>Nilda Cosco<\/span><\/a> creating an <\/span>interactive map tool with 360\u00b0 videos<\/span><\/a>. \u201cMuntazar approached me and wanted to integrate the exploratory grant within this course,\u201d said Delcambre. Work on the project formally began on September 1, 2017.<\/span><\/p>\n

Initially, Monsur wanted to create a \u201cvirtual field trip\u201d of a real site using 360\u00b0 videos students can view through a VR headset. \u201cThe field trips are really important for students to go out and see how design is translated into real construction,\u201d said Monsur. However, it proved to be challenging getting the timing of shoots aligned with days students were out working on the sites. Other complicating factors, such as unpredictable weather and construction delays, also hindered their progress. Monsur decided that they would create a completely simulated environment with viewable 360\u00b0 videos within it. \u201cThe main goal is still the same, [which is] trying to understand how abstract design is constructed in reality,\u201d said Monsur. <\/span><\/p>\n

Salam added, \u201cWe are trying to create an environment in Unity and incorporate these videos of particular construction processes so that students can immerse themselves in this 3D environment and learn the construction process.\u201d <\/span><\/p>\n

The DELTA team was able to record several videos of students taking the <\/span>Design + Build Studio<\/span><\/a> (LAR 500) course, co-taught by Delcambre and Assistant Professor of Practice, <\/span>Jesse Turner<\/span><\/a>. These short videos will be viewable within the VR environment as hot spots demonstrating the process of moving from a design to construction of a 3D object. These videos combined with the VR environment will allow students to get a similar experience without physically being at a specific site. They will be able to select different areas to watch videos documenting the construction process as they move around the 3D space. <\/span><\/p>\n

What is exciting about this project is that it is DELTA\u2019s first simulated VR environment viewable through a VR headset. \u201cIt is something we haven\u2019t done before,\u201d said Huckaby. DELTA has completed several projects involving 360\u00b0 videos in the past, but has never constructed an immersive, 3D environment with VR headset capabilities until now. Spherical videos are considered a form of VR when viewed through a VR headset, but the viewer is not able to move freely within a 3D space. \u201cAnother key difference is that 360\u00b0 video is static content\u2014once it is recorded, that is what you get,\u201d said Huckaby. <\/span><\/p>\n

According to Delcambre, landscape architecture students often have trouble visualizing their 2-D drawings as 3D objects. Many do not have experience working with different landscape materials and seeing how they fit together. \u201cYou lack that mindset since you\u2019re not the one building it,\u201d said Earnest. <\/span><\/p>\n

Monsur and Delcambre hope that creating an interactive, simulated environment will allow students to become familiar with different materials and methods, especially international students, who have to adjust from metric measurements to feet and inches. \u201cSeveral of our international students during the Design + Build [course] said they had drawn a particular detail several times and didn\u2019t understand what the material was,\u201d said Delcambre. This simulated environment will allow students to view different structures and materials throughout the course, making it easier for them to visualize moving from a drawing to a constructed object. <\/span><\/p>\n

The models they are building in the 3D environment will also showcase different forms of sustainable infrastructure. These designs focus particularly on how water moves through an urban landscape. The design will include stormwater control measures (SCMs) such as rain gardens and structural soil which helps filter water as it moves through the ground.<\/span><\/p>\n

There will be a version of the 3D environment for viewing in class with a VR headset, but for those who cannot be physically present in the classroom, they can also access the web version. Delcambre hopes the web version of the immersive environment will be helpful for distance education students who take landscape architecture courses. \u201cIf you\u2019re not using a headset, or you don\u2019t have a lot of equipment, you can still experience it just from your web browser,\u201d said Huckaby. <\/span><\/p>\n

Currently, the DELTA team is working on finishing up the VR interface. They plan to release a pilot version of the environment to be tested by Delcambre\u2019s LAR 457 students in June 2018.<\/span><\/p>\n

Challenges<\/span><\/h3>\n

Since this is DELTA\u2019s first project involving construction of a 3D environment for VR, the team has faced some unique challenges. The DELTA team takes high-detail models provided by Monsur and Delcambre and converts them into more efficient, low-poly models. \u201cWe need to be as efficient as possible, but we also want it to look really good,\u201d said Huckaby. Finding the correct balance between quality and performance is a major challenge.<\/span><\/p>\n

The process of building an environment in Unity is also time-consuming. Prior experience developing simulations in Unity, such as creating a soil sampling exercise for HS 200, gave the team some familiarity with this type of work, speeding up the development process. The team can also save time by reusing 3D models provided in Unity model packages from previous projects for objects like trees and other plants. However, they have to design their own 3D models of any structure or object not included in these packages. <\/span><\/p>\n

Goals<\/span><\/h3>\n

Monsur and Delcambre hope to expand the project after it is completed. \u201cWe have students that want to learn more [about] VR,\u201d said Delcambre. \u201cIt would be fantastic to have [more of] that type of learning happening in the College of Design.\u201d She wants to incorporate VR into her introduction to landscape architecture course. Monsur and Delcambre intend to apply for another DELTA grant in Spring 2019. <\/span><\/p>\n

Monsur sees VR as a technology that will significantly impact landscape architectural education. \u201cVR is the future of presentation for architecture and landscape architecture,\u201d said Monsur. \u201cSoon it is going to take over all other formats like drawing, photographs or renderings. It gives you such a big advantage when you are presenting to the client as if the space is already built. The client has the advantage of looking around, moving around a space that\u2019s not yet built.\u201d<\/span><\/p>\n

They believe the 3D environment can be used for horticulture, geospatial, natural resources and civil engineering courses as well. On the website, Monsur and Delcambre will be able to share their designs, pictures, videos and construction projects with other professors and students.<\/span><\/p>\n

The DELTA team sees their work serving as a touchstone for future VR projects. \u201cOne of our goals is to break new ground with VR development since that is something we haven\u2019t done before,\u201d said Huckaby.<\/span><\/p>\n
