示例1: intersect
Intersection Model::intersect(Ray r) {
Intersection xsect;
xsect.init();
Vector3 e = invMat.transform_point(r.e);
Vector3 d = normalize(invMat.transform_vector(r.d));
Mesh::MeshTriangleList m;
m = kdtree->Test(e, d);
real_t min_dis = 9999999.9;
// Convert each triangle into a "Triangle" Class object, and pass
// it to that class's intersection test. Yay DRY.
for (size_t i = 0; i < m.size(); i++) {
MeshTriangle tri = m[i];
Triangle t;
for (size_t j = 0; j < 3; j++) {
Triangle::Vertex& tv = t.vertices[j];
const MeshVertex& mv = mesh->vertices[tri.vertices[j]];
tv.position = mv.position;
tv.normal = mv.normal;
tv.tex_coord = mv.tex_coord;
tv.material = material;
}
t.position = position;
t.orientation = orientation;
