cee::geo::DataIndexedTriangles

class DataIndexedTriangles : public Data 

Data structure representing indexed triangles data for a geometry part

Each triangle is defined by three connectivity indices into the vertices array. The created data will have indices.size()/3 triangles.

Public Functions

DataIndexedTriangles(): Constructs an empty data object.

DataIndexedTriangles(const std::vector<Vec3d> &vertices, const std::vector<unsigned int> &indices)

Constructs triangle data defined by an array of vertices and an array of connectivity indices.

Each triangle is defined by three indices. The created data will have indices.size()/3 triangles.

// Triangle vertices and indices
std::vector<cee::Vec3d> triangleVertices;
triangleVertices.push_back(cee::Vec3d(0.0, 0.0, 2.0));
triangleVertices.push_back(cee::Vec3d(2.0, 0.0, 2.0));
triangleVertices.push_back(cee::Vec3d(1.0, 0.0, 3.0));
std::vector<unsigned int> triangleIndices = { 0, 1, 2 };

// Create a triangle data part using the vertices and connectivities
cee::PtrRef<cee::geo::DataIndexedTriangles> triangleDataPart = new cee::geo::DataIndexedTriangles(triangleVertices, triangleIndices);

virtual Type type() const: Returns Data::INDEXED_TRIANGLES.

virtual BoundingBox boundingBox() const: Returns the bounding box of the part data.

std::vector<Vec3d> vertices() const

Returns array of vertices used to define the triangles.

std::vector<unsigned int> indices() const

Returns the array of connectivity indices used to tell which coordinates to build up the each triangle.

Each triangle is defined by three indices. The data will have indices.size()/3 triangles.

setIndices

void setIndices(const std::vector<unsigned int> &indices)

Sets connectivity indices used to tell which coordinates to build up each triangle.

The array must contain 3 indices per triangle.
