| the visual fidelity possible on Meta Quest devices. It has been built using <a |
| href=\"https://developer.oculus.com/documentation/unity/unity-isdk-interaction-sdk-overview/\">*Interaction |
| SDK*</a>\_for interactions, <a href=\"https://developers.meta.com/horizon/documentation/unity/move-overview\">*Movement |
| SDK*</a> for full body tracking, and <a href=\"https://developers.meta.com/horizon/documentation/unity/meta-xr-audio-sdk-unity\">*Audio |
| SDK*</a> for spatialized sounds. It is designed to be used primarily for the |
| best intended hand-tracking experience but also provides full controller support.\n\nInspired |
| by the age of sail and exploration, you play as a new deckhand aboard the _Polaris_, |
| a ship with a dedicated crew on a quest to find a mythical sunken treasure at |
| Ocean Deep.\n\nYou can play this showcase for free on the <a href=\"https://www.meta.com/experiences/north-star/28679538058299918/\">Horizon |
| Store</a>.\n\n\n# Showcase Features\n\nEach of these features have been built |
| to be accessible and scalable for other developers to take and build upon in |
| their own projects.\n\n\n## Ocean\n\n*North Star* includes a highly customizable |
| ocean system that is optimized to be quite performant on device while achieving |
| a visually realistic ocean volume. Developers can control the hue, activity/choppiness |
| of the water, reflections, height and intensity of waves through the inspector, |
| and transition smoothly between profiles.\n\n\n## Boat Movement\n\nMost of the |
| game takes place *Polaris* as it sails through a variety of ocean conditions, |
| *North Star* achieves a variable motion on the boat to simulate the natural bobbing |
| and swaying of sailing while paying special heed to the player\u2019s comfort.\n\n\n## |
| Comfort Settings\n\nBefore starting the game, players can set up their experience |
| through the main menu. In addition to seated mode and height detection, they |
| can elect their sailing comfort level. There are 4 comfort levels to choose from |
| (Calm, Choppy, Rough, Sailor), with the lowest dampening the natural movement |
| of the boat to be negligible, and each following level intensifying the sailing |
| experience further toward the highest and most realistic level.\n\n\n## Time |
| of Day\n\nIncluded in the *North Star* project is a Time of Day system, where |
| designers can define Environment Profiles to determine the sun/moon position, |
| color of the sky, directional light, and more. Designers can set up multiple |
| Environment Profiles and either transition between them over a duration, or switch |
| to new profiles immediately (ie: during a teleport or load screen).\n\n\n## Ropes\n\n*North |
| Star* was built with the intention of providing the most realistic and tactile |
| rope interactions available in VR gaming. Ropes respond naturally when interacted |
| with, allowing players to wrap them around other objects (like securing the rope |
| from the mainsail to a cleat), swing and propel other objects (like a life buoy) |
| and generally behave realistically when thrown, pulled and jiggled.\n\n\n## Interactables\n\nUtilizing |
| Meta\u2019s Interactions SDK and built specifically with hand tracking in mind, |
| there are a variety of unique interactions available within the *North Star* |
| experience:\n\n**Rope & sail manipulation**: Pull ropes to raise the mainsail |
| and secure it off on a cleat, untie to furl the sails.\n\n**Cranks**: Use a crank |
| to re-angle the sails to line them up with windsocks and catch the breeze!\n\n**Levers**: |
| Pull the lever to begin the descent of the Diving Bell.\n\n**Harpoon Gun**: Load |
| bolts, pull back the tension, aim and hit the button to let loose a harpoon! |
| Wind the cranks to retrieve cargo salvaged from the ocean.\n\n**Spyglass**: Extend |
| the spyglass and hold it to an eye to magnify your view and look through fog.\n\n**Object |
| Manipulation**: Pick up and interact naturally with a number of objects found |
| aboard the *Polaris*, and take your turn navigating at the helm!\n\n\n## Narrative |
| & NPCs\n\nEngage in an exciting adventure inspired by the age of exploration! |
| Join the dynamic crew of the *Polaris* as it sets sail to find a mythical and |
| mysterious treasure in the depths of the ocean known as Ocean Deep. Fully animated |
| and voiced NPCs guide you through your adventure, utilizing lipsync technology |
| when addressing you, the new deckhand.\n\n\n## Free Sailing\n\nJump into free |
| sailing mode to put everything you\u2019ve learned along your journey to the |
| test! Freely manipulate the sails to catch the wind and feel the ocean rock you |
| under your feet.\n\n\n# Source Voiceovers\n\nTo protect the voiceover talent |
| employed for this project, the original source VO files that are utilized in |
| the store release of North Star are not present in this public project repository. |
| Instead all original source VO files have been replaced with rudimentary placeholder |
| generated VO.\n\nAll original VO talent was sourced from the <a href=\"https://bigmouthvoices.com/\">Big |
| Mouth Voices online agency</a>.\n\n\n# Documentation\n\nMore information is available |
