Bloktopia

<h2 id="header-0">HOT TOPIC: Avatar Optimisation</h2><blockquote>Developer Diaries aim to give a transparent view to our community on how the build of Bloktopia is progressing. We value your loyalty and passion for our project, and we will be sharing as much information as we can about 1 specific feature — hopefully at the end of each week! We will continue to work in an agile manner, and will be adapting and optimising our roadmap continuously. That is the nature of building a metaverse. So, some things we share here, might not ever come to fruition, but our goal will be to set clear expectations and communicate with you all about the upcoming roadmap and priorities.</blockquote>This <a href="https://medium.com/&#64;bloktopia/bloktopia-developer-diaries-1-1827868741ba" rel="noopener noreferrer nofollow">weekly Developer Diary update</a> is focused on Avatar optimisation- specifically Avatar LOD and the unique challenges faced when developing the Bloktopia metaverse.<h2 id="header-1">What is LOD?</h2>LOD simply stands for level of detail. It’s the process of making less detailed versions of models, such as digital Avatars, that are viewed when they’re further away from the camera.Each model or character in a game has multiple LODs, ranging from high detail and decreasing gradually to low detail. High detail LODs have the best graphics, but come at the cost of memory. Whereas low detail LODs use less memory and create less work for the graphics card, but deter from the experience quality.As we continue to develop Bloktopia, we’ll blend between high and low detail when necessary to keep the performance as efficient as possible. We do this when content is far away, meaning content in the distance is low detail where the player can’t perceive the difference. This allows us to keep a high frame rate whilst maximising the content on screen.In a VR metaverse like Bloktopia, this form of optimisation is crucial for UX, as we have large scale environments with many avatars all being displayed on relatively low powered VR headsets.This optimisation can be seen in the examples below:<img src="https://miro.medium.com/max/3788/1*UD9RKXky1PFX9hreRRQcGA.png" /><img src="https://miro.medium.com/max/3542/1*4k6K9nylTAuW-Z9d5h_-rg.png" />(From left to right) High LOD down to Low LODThe set of three avatars show a LOD ranging from 100% on the left, down to 60% in the middle and finally 10% on the right. When the avatars are all close up to the camera and equidistant, the LOD difference is easy to see.However, if the same LOD range is applied to a set of avatars at varying distances, it’s significantly changes the perspective with the difference in graphic quality no longer visible. This effect can be seen both through VR and non-VR versions of Bloktopia.<img src="https://miro.medium.com/max/3680/1*a148BmA7WdBDzVsHIWDWFA.png" /><img src="https://miro.medium.com/max/3882/1*6pzL2E98ULpX2eQMwT3sHA.png" />(From left to right) High LOD down to Low LOD now less prominent at a further distance<h2 id="header-2">Unique challenges for Bloktopia:</h2>Normally, in game development, all LODs can be built before the game is shipped. However, in the metaverse we allow players to look unique and bring in custom items, such as digital wearable NFTs. These items need to have their LODs created dynamically, making the process less uniform.We have over come this unique challenge by utilising a series of tools to build this process. We use Simplygon, along with a collection of internal tools, to create these optimised characters and apply the output back into the original character seamlessly.Simplygon allows us to specify a set of rules to optimise our geometry. In the examples below, the characters on the left of each image are high detail Avatars. Where as on the right of each image, the Avatars are the 10% LODs created by Simplygon.<img src="https://miro.medium.com/max/2186/1*hPKr6QAJifybydrgWSnPVQ.png" /><img src="https://miro.medium.com/max/1544/1*ADwUvhJx3RH0eBLXPITAFg.png" />Simplygon Wireframes are c.7x smaller than the High LOD WireframesWe can also utilise Ready Player Me’s new API. Recently, RPM have updated their service to support the creation of optimised meshes. Whilst this is still an ever evolving space, we will make use of this in combination of our own tools for optimal results.<h2 id="header-3">Why is the level of optimisation required?</h2>Like we touched upon in Developer Diaries <a href="https://medium.com/&#64;bloktopia/bloktopia-developer-diaries-8-e00777caa693" rel="noopener noreferrer nofollow">#12</a> when showcasing asset optimisation, user experience for Bloktopians is at the forefront of our decision making. These optimisations on assets and avatars allow for a significantly higher amount of users within the Bloktopia metaverse without compromising on the quality of the UX, primarily as a result of the framerate not dropping below the minimum threshold for performance.<h2 id="header-4">What’s next?</h2>As we continue to develop and optimise Bloktopia for the ultimate metaverse experience, the next steps to automate in our toolchain is the optimisation of texture resolutions, and the creation of new optimised material versions to enhance the UX of Bloktopia even further.<h2 id="header-5">About Bloktopia</h2>Bloktopia is a VR skyscraper made up of 21 floors to commemorate 21 million Bitcoin.
