UmbraMesh struct

3D triangle mesh

The mesh consists of a set of vertices with optional attributes, and a set of triangles refering to the vertices. For some configurations, meshes should be one sided with consistent triangle winding (see Parameters). Mesh topology is generally irrelevant to the results of Umbra.

Public variables

const UmbraFloat3* vertices
Vertex positions.
const UmbraFloat3* normals
Vertex normals (optional), either null or the same size as vertices.
const UmbraFloat3* tangents
Vertex tangents (optional), either null or the same size as vertices.
const UmbraFloat2* texCoords
Vertex texture coordinates, required when used with texturing but otherwise optional.
const UmbraFloat4* colors
Vertex colors as RGBA values (optional), either null or the same size as vertices.
const UmbraInt3* triangles
Triangle list, triplets of indices to vertex arrays.
const UmbraTriangleFlags* triangleFlags
Per-triangle optional flags.
uint32_t vertexCount
Size of vertices array.
uint32_t triangleCount
Size of triangles array.

Variable details

const UmbraFloat2* UmbraMesh::texCoords

Vertex texture coordinates, required when used with texturing but otherwise optional.

Either null or the same size as vertices.
