While working on a virtual reality application for painting graffiti on walls our team had difficulties with the implementation of smooth painting with spray paint.
The drawing process itself is calculated mathematically using linear interpolation. We launch a beam from a can of paint and aim at the texture of the wall on which we will paint, after which we calculate the pixels, and the paint is transferred to the wall.
The main difficulty occurred when moving quickly with a can. The paint did not fill all the intermediate points, but only separate ones, as a result, voids appeared in the filling with color. Naturally, at the same time, the drawing process lost its realism and smoothness and became uncomfortable. The reason for this was the use of Unity’s built-in math, which could not cope with a large number of miscalculations.
In order to solve this problem, we decided to use third-party libraries:
- Hybrid renderer — provides systems and components for rendering ECS entities. Hybrid Renderer is not a render pipeline: it is a system that collects the data necessary for rendering ECS entities and sends this data to Unity’s existing rendering architecture.
- BurstCompiler — it translates from IL/.NET byte code to highly optimized native code using LLVM. It is released as a unity package and integrated into Unity using the Unity Package Manager.
- Unity C# Job System — lets you write simple and safe multithreaded code that interacts with the Unity Engine for enhanced game performance.
In the video below, you can see the difference in performance before and after using third party libraries.
After the implementation of the above libraries, the efficiency of the application was improved by 90-100%.

OpenAI’s Sora & ElevenLabs: How Will They Impact Game Development? The emergence of tools like OpenAI’s Sora and ElevenLabs sparks discussions about their potential impact on the industry. Amidst the ongoing buzz about AI revolutionizing various fields, game developers find themselves at the forefront of this technological wave. However, the reality may not be as revolutionary as some might suggest. Concerns Amidst Excitement: Unraveling the Real Impact of AI Tools in Game Development Today’s AI discussions often echo the same sentiments: fears of job displacement and the idea that traditional roles within game development might become obsolete. Yet, for those entrenched in the day-to-day grind of creating games, the introduction of new tools is seen through a more pragmatic lens. For game developers, the process is straightforward – a new tool is introduced, tested, evaluated, and eventually integrated into the standard development pipeline. AI, including platforms like Sora and ElevenLabs, is perceived as just another tool in the toolkit, akin to game engines, version control systems, or video editing software. Navigating the Practical Integration of AI in Game Development The impact on game development, in practical terms, seems to be more about efficiency and expanded possibilities than a complete overhaul of the industry. Developers anticipate that AI will become part of the routine, allowing for more ambitious and intricate game designs. This shift could potentially lead to larger and more complex game projects, offering creators the time and resources to delve into more intricate aspects of game development. However, there’s a sense of weariness among developers regarding the constant discussion and hype surrounding AI. The sentiment is clear – rather than endlessly discussing the potential far-reaching impacts of AI, developers prefer practical engagement: testing, learning, integrating, and sharing insights on how these tools can be effectively utilized in the real world. OpenAI — for all its superlatives — acknowledges the model isn’t perfect. It writes: “[Sora] may struggle with accurately simulating the physics of a complex scene, and may not understand specific instances of cause and effect. For example, a person might take a bite out of a cookie, but afterward, the cookie may not have a bite mark. The model may also confuse spatial details of a prompt, for example, mixing up left and right, and may struggle with precise descriptions of events that take place over time, like following a specific camera trajectory.” So, AI can’t fully create games and its impact might be limited. While it could serve as a useful tool for quickly visualizing ideas and conveying them to a team, the core aspects of game development still require human ingenuity and creativity. In essence, the introduction of AI tools like Sora and ElevenLabs is seen as a natural progression – a means to enhance efficiency and open doors to new creative possibilities. Rather than a radical transformation, game developers anticipate incorporating AI seamlessly into their workflow, ultimately leading to more expansive and captivating gaming experiences.

In this article, we will explore the impact of augmented and virtual reality on national parks, specifically how they are changing our experience of visiting natural landscapes. We focus on free virtual tours that allow us to see the beauty of national parks without leaving home. We will also reveal the main advantages of augmented reality, which enrich the visiting of real parks with the help of digital content with interesting information. In particular, we will share our experience of creating tourist VR excursions using the example of the Carpathian Mountains Virtual Tour and Medieval Fortress Virtual Journey. We will also explore other famous AR/VR use cases, e.g., the State Parks of California, giving us a unique perspective on our national parks’ historical and ecological significance. Discovering Benefits of AR and VR in National Parks Virtual and augmented reality offer such benefits to national parks as Getting informative content on the spot. When visiting parks and other historical places, visitors usually don’t know about this or that type of plant or even in which part of the park they are. With the help of an AR application, a tourist can simply point the screen at a particular plant and get additional information about it. Read also: The Ways AR Redefines Modern Tourism Speaking about orientation in place, AR navigation will come in handy here, which guides the tourist in the right direction with the help of digital pointers. Read also: From Outdoors to Indoors: AR Navigation as Game-Changer Visiting places that aren’t accessible for you. During the COVID-19 pandemic and home isolation, virtual tours of museums or national parks were one of the popular alternatives to visiting real tourist locations. Even though the pandemic began to gradually fade away, virtual tours continue to be relevant. By visiting free tours on museums or park websites, an Internet user saves money on the ticket, car fuel, and transportation. Especially when a person does not always have an opportunity to get to the place where, perhaps, he would like to go. “The advantage is that you can go somewhere and experience the same feelings without leaving your home. Virtual guides have musical accompaniment, the effect of presence thus allows you to immerse yourself in the environment. This is all about VR. Plus, not all of us can go to Papua New Guinea or somewhere else to look at bamboo, baobabs, etc. Or go on safari. Therefore, these are opportunities to visit somewhere without spending additional funds,” said Oleksandr Ivanov, project manager of Qualium Systems. Drawing attention to ecology, rare plants and animals. As you know, there are more than 35,000 species of endangered plants and animals in the world, 99% of which are endangered due to human activities. With virtual and augmented reality for parks that are the home for these species of animals, it becomes possible to tell about these endangered species to a wider audience. As of July 2023, there are almost 7 billion people in the world who have smartphones, which is more than 86% of the entire population of the planet. Qualium System’s Virtual Tours of National Parks Qualium Systems has great experience in developing VR excursions. Carpathian Mountains Virtual Tour is an application for Meta Quest, created as part of The World Of Carpathian Rosettes — Activities For Preserving The Cultural Uniqueness Of The Carpathians project by the Euroregion Carpathians — Ukraine association with the financial support of the European Union. The main goal of this program is to preserve the cultural uniqueness of the Ukrainian Carpathians. The main challenge in the development of this virtual tour was to introduce more than 260 photo and video materials into the program while providing the VR headset users with such an experience as if they were visiting a real museum. In this application, a tourist can explore virtual settlements in the Carpathians, both with the effect of presence in these settlements and from a bird’s eye view. There is also the option of a “bicycle trip” available. A tourist can “ride” along the Franko route, which is a path in the forest, famous Ukrainian poet Ivan Franko liked to travel. Also, our developers are working on another virtual tour of the medieval fortress in the Ukrainian town of Tustan. Unlike the previous tour, a VR headset user will not only be able to see the digital environment with exhibits but also interact with them. “With the help of VR, you can not only be there, in that museum, but also take the artifacts, examine, bring them up to your forehead. You could see everything down to every crack,” said Oleksandr Ivanov, project manager of Qualium Systems. Unveiling Diverse Use Cases of AR and VR in National Parks Our company pays attention to virtual tours and giving people the opportunity to see places that are inaccessible to them due to various circumstances. We constantly monitor the latest trends in the modern IT industry, and there are other famous examples that will be mentioned later. Virtual Reality Adventures in California State Parks The California Department of Parks and Recreation has introduced virtual and augmented reality tours for 9 parks located in the state of California. In the Virtual Adventurer mobile app, tourists get a guided tour that tells the story of each of the parks, including Colonel Allensworth State Historic Park, Montana de Oro State Park, Old Town San Diego Historic Park, and others. Moreover, futuristic holograms and 3D reconstructions are also involved. “The app also supports and enhances the department’s Reexamining Our Past Initiative by developing content for parks that tells a more complete, accurate, and inclusive history of people and places,” said California State Parks Director Armando Quintero. Great Barrier Reef’s Virtual Realms As mentioned above, virtual excursions allow gadget users to get to places they would be unlikely to get to in real life. The same is true for the underwater attractions. Not every tourist wants to spend their time and money not only to reach, for example,…
