It started as a purely educational project but grew as the project progressed. This year there has been a lot of momentum which allowed me to do a public beta release (v0.9) a few months ago. This week I launched the next public beta release: v0.10!</p> <p>The project is free and open sourced under the MPL-2.0 license. It runs on older hardware (GTX 10 series) and anything more recent as well.</p> <h2> Use Cases </h2> <p>1) People using the source code for learning purposes</p> <p>2) People using it as a rendering starting point if they want to build their own game engine or integrate it into a visualization/modeling tool</p> <h2> Sample Images </h2> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--rxApUEEN--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/np9aly8jtn66fv0mgi4c.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--rxApUEEN--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/np9aly8jtn66fv0mgi4c.png" alt="San Miguel 1" width="800" height="450"></a></p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--SjVndm_U--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2ac6m8dl4egdd6y371wb.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--SjVndm_U--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2ac6m8dl4egdd6y371wb.png" alt="San Miguel 2" width="800" height="450"></a></p> <p>(3D Model: San Miguel)</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--LGwlw6JZ--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/elj86ol2jiy5hzfpn4dq.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--LGwlw6JZ--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/elj86ol2jiy5hzfpn4dq.png" alt="Sponza" width="800" height="443"></a></p> <p>(3D Model: Sponza)</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--irC73qS5--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zawbs0avl2m330xsjie8.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--irC73qS5--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zawbs0avl2m330xsjie8.png" alt="Junk Shop" width="800" height="449"></a></p> <p>(3D Model: Junk Shop)</p> <h2> Features </h2> <h4> Graphics </h4> <ul> <li>Physically based metallic-roughness pipeline</li> <li>Realtime global illumination</li> <li>Spatiotemporal image denoising</li> <li>Raymarched volumetric lighting and shadowing</li> <li>Cascaded shadow mapping</li> <li>Deferred lighting</li> <li>Mesh Level-Of-Detaul (LOD) generation and selection</li> <li>GPU Frustum Culling</li> <li>Screen Space Ambient Occlusion (SSAO)</li> <li>Tonemapping</li> <li>Fog</li> <li>Bloom</li> <li>Fast Approximate Anti-Aliasing (FXAA)</li> <li>Temporal Anti-Aliasing (TAA)</li> </ul> <h4> Engine </h4> <ul> <li>Pool allocators</li> <li>GPU memory allocators/managers</li> <li>Multi threaded utilities</li> <li>Concurrent hash map</li> <li>Entity-Component System (ECS)</li> <li>Logging</li> </ul> <h2> Links </h2> <p><a href="https://github.com/KTStephano/StratusGFX">GitHub Repo</a></p> <p><a href="https://www.youtube.com/watch?v=dj0wVxwd1ng">Video Tech Demo</a></p> <p>Thanks!</p> showdev opensource gamedev programming
