示例1: computeNormals
void TriMesh::computeNormals() {
// skip
// Calculate triangle normals
for(int i = 0; i < m_triangles.size(); i++){
glm::vec3 v1; glm::vec3 v2; glm::vec3 v3;
HalfEdge* tempLeader = m_triangles[i]->getLeadingHalfEdge();
v1 = tempLeader->getSourceNode()->m_pos_;
tempLeader = tempLeader->getNext();
v2 = tempLeader->getSourceNode()->m_pos_;
tempLeader = tempLeader->getNext();
v3 = tempLeader->getSourceNode()->m_pos_;
m_triangles[i]->m_N_ = calculateNormal(v1,v2,v3);
}
// Calculate vertex normals by averaging triange normals
for(int i = 0; i < m_nodes.size(); i++){
Node n = m_nodes[i];
HalfEdge* startEdge = n.getLeadingHalfEdge();
Triangle* startTriangle = startEdge->getTriangle();
glm::vec3 accNormal = startTriangle->m_N_;
int triangleCount = 1;
for(HalfEdge* tempEdge = startEdge->getVtxRingNext(); tempEdge != startEdge; tempEdge = tempEdge->getVtxRingNext()){
if (tempEdge == NULL)
break;
accNormal += tempEdge->getTriangle()->m_N_;
triangleCount++;
}
glm::vec3 count = glm::vec3(triangleCount);
m_nodes[i].m_N_ = accNormal/count;
}
// unskip
}示例2: getNode
/** Return node no ix from triangle.
* \param ix is either 0, 1 or 2.
*/
Node* getNode(size_t ix) {
HalfEdge *he = m_he_;
for(size_t i=0; i<ix; i++) {
he = he->getNext();
}
return he->getSourceNode();
}示例3: edge
TEST(HalfEdgeTest, TestGetNext)
{
using T = float;
const HalfEdge<T> edge(nullptr, nullptr);
EXPECT_EQ(nullptr, edge.getNext());
