Example #1

File: cubic_semi_lagrangian3.cpp Project: doyubkim/fluid-engine-dev

std::function<double(const Vector3D&)>
CubicSemiLagrangian3::getScalarSamplerFunc(const ScalarGrid3& source) const {
    auto sourceSampler = CubicArraySampler3<double, double>(
        source.constDataAccessor(),
        source.gridSpacing(),
        source.dataOrigin());
    return sourceSampler.functor();
}

Example #2

File: main.cpp Project: doyubkim/fluid-engine-dev

void triangulateAndSave(const ScalarGrid3& sdf,
                        const std::string& objFilename) {
    TriangleMesh3 mesh;
    marchingCubes(sdf.constDataAccessor(), sdf.gridSpacing(), sdf.dataOrigin(),
                  &mesh, 0.0, kDirectionAll);

    std::ofstream file(objFilename.c_str());
    if (file) {
        printf("Writing %s...\n", objFilename.c_str());
        mesh.writeObj(&file);
        file.close();
    } else {

        exit(EXIT_FAILURE);
    }
