void | addVertex (const Ogre::Vector3 &position) |
Add a vertex to the mesh (no normal defined). If using this function only (not using addTriangle()) it is assumed that triangles are added by specifying the 3 vertices in order (3 consecutive calls to this function). This means there must be 3*n calls to this function to add n triangles. If addTriangle() is used, indexing in the defined vertices is done. More... | |
void | addVertex (const Ogre::Vector3 &position, const Ogre::Vector3 &normal) |
Add a vertex to the mesh with a normal defined. If using this function only (not using addTriangle()) it is assumed that triangles are added by specifying the 3 vertices in order (3 consecutive calls to this function). This means there must be 3*n calls to this function to add n triangles.If addTriangle() is used, indexing in the defined vertices is done. More... | |

This class allows constructing Ogre shapes manually, from triangle lists.
For example: Assuming we have a set of mesh triangles represented like this:
struct Triangle { unsigned v1, v2, v3; // index for the 3 vertices that make up a triangle }; std::vector<Triangle> triangles; std::vector<Ogre::Vector3> vertices; std::vector<Ogre::Vector3> normals; // normal at every vertex
we can use this class to render the mesh as follows:
rviz::MeshShape *shape = new MeshShape(scene_manager); mesh->estimateVertexCount(vertices.size()); mesh->beginTriangles(); for (std::size_t i = 0 ; i < vertices.size() ; ++i) mesh->addVertex(vertices[i], normals[i]); for (std::size_t i = 0 ; i < triangles.size() ; ++i) mesh->addTriangle(triangles[i].v1, triangles[i].v2, triangles[i].v3); mesh->endTriangles();
