YCB Model Characteristics

The YCB set includes 77 objects, ranging from rigid items like tools to deformable objects like cloths. Relevant to casinos, the “credit card” model mimics the shape and texture of playing cards, while cylindrical objects like the “tuna can” serve as proxies for chips. Each model comes with high-resolution RGB-D scans, textured meshes, and physical properties (e.g., weight, friction), enabling realistic rendering and physics simulation. Available in formats like STL and OBJ, these models are compatible with game engines and 3D modeling software like Blender.

Open-Access Availability

Hosted on the YCB website, the models are freely accessible under a Creative Commons license, making them a cost-effective alternative to proprietary assets. The dataset includes metadata, such as center of mass and material properties, which enhance simulation accuracy in virtual environments. Community contributions ensure ongoing updates, with protocols for proposing new objects, allowing developers to suggest casino-specific items like dice or roulette wheels.

Benchmarking Protocols

While YCB is primarily known for robotics benchmarking (e.g., pick-and-place tasks), its models are equally valuable for virtual simulations. The dataset’s protocols provide guidelines for object interaction, such as grasping or stacking, which can be adapted to simulate player actions like dealing cards or stacking chips in a virtual casino.

Leveraging YCB Models for Virtual Casinos

YCB 3D models can be integrated into virtual casino development to create realistic and interactive environments. Their versatility supports various aspects of casino design, from game mechanics to aesthetic details.

Modeling Casino Objects

The YCB “credit card” model, with its thin, rectangular shape, is a direct stand-in for playing cards. Developers can apply custom textures (e.g., ace of spades) to create a full 52-card deck, ensuring visual authenticity. For chips, cylindrical YCB objects like the “tuna can” or “coffee mug” can be rescaled and textured to resemble poker chips, with weights (11–14 g) approximated using YCB’s physical data for accurate physics. Other objects, like the “dice” or “wood block,” can simulate dice or game tokens.

Using Blender or Maya, developers can modify YCB meshes to match casino aesthetics, such as adding metallic finishes to chips or embossed designs to cards. These customized models are then imported into Unity or Unreal Engine, where physics engines like PhysX simulate realistic interactions, such as cards sliding across a table or chips stacking.

Creating Interactive Game Mechanics

YCB models support dynamic interactions critical to casino gameplay. In Unity, developers can use YCB’s physical properties to define collision behaviors, ensuring cards flip naturally or chips stack without clipping. For example, a virtual blackjack table can use the “credit card” model for dealing, with scripts controlling shuffle animations based on YCB’s pick-and-place protocols. VR controllers, like those for Oculus Rift, allow players to grab and place chips, leveraging YCB’s grasp metrics to ensure intuitive handling.

Multiplayer features, powered by Photon or Mirror networking, enable real-time interactions, such as players betting chips or dealers distributing cards. YCB’s standardized models ensure consistent rendering across devices, reducing latency and enhancing cross-platform compatibility.

Designing Immersive Environments

Beyond game objects, YCB models contribute to the broader casino environment. Items like the “wine glass” or “pitcher” can decorate virtual bars, while “books” or “boxes” furnish VIP lounges. These assets, combined with custom 3D models for slot machines or chandeliers, create a cohesive aesthetic inspired by real-world casinos like The Venetian in Macau. Unreal Engine’s Nanite technology enhances rendering of high-polygon YCB models, delivering photorealistic visuals even in large-scale environments.

Lighting plays a crucial role in immersion. Developers can use YCB’s texture data to apply reflective materials to chips or cards, ensuring they catch dynamic lighting from virtual chandeliers or neon signs. Ray-tracing in Unreal Engine amplifies these effects, creating a glamorous atmosphere.
