C++ (Cpp) TransformState::matrixFor Examples

Example #1

File: source.cpp Project: ariosx/mapbox-gl-native

void Source::updateMatrices(const mat4 &projMatrix, const TransformState &transform) {
    for (std::pair<const Tile::ID, std::unique_ptr<Tile>> &pair : tiles) {
        Tile &tile = *pair.second;
        transform.matrixFor(tile.matrix, tile.id);
        matrix::multiply(tile.matrix, projMatrix, tile.matrix);
    }
}

Example #2

File: geometry_tile.cpp Project: mapbox/mapbox-gl-native

    std::unordered_map<std::string, std::vector<Feature>>& result,
    const GeometryCoordinates& queryGeometry,
    const TransformState& transformState,
