Introduction

RXMeshStatic is the main class for representing and processing static triangle meshes with fixed connectivity—meshes that do not change topology at runtime. This class constructs a compact, patch-based internal representation of the input mesh and exposes interfaces for managing mesh attributes, launching element-wise operations, and querying connectivity.

The input to RXMeshStatic is typically a .obj file containing a triangle mesh. During construction, RXMesh parses the mesh and builds a data structure optimized for GPU execution. RXMesh uses handles to represent mesh elements, which can be converted to continuous indices when needed. For details, see Indexing.

Users interact with RXMeshStatic by defining attributes associated with vertices, edges, or faces. Each attribute is defined by its element type, value type, and dimensionality. Attributes can be allocated on either the host, device, or both and transferred explicitly between them. See Attribute Management for more.

Mesh operations are expressed either through parallel iteration over individual elements (e.g., for_each_vertex) or via query kernels (e.g., run_query_kernel<Op::FV>) that provide access to local neighborhoods. These kernels execute entirely on the GPU and support computations that depend on adjacent elements. See Operations for more information.
