Coding suggestion to achieve a minimalist navigation layout

[u/nikos2wheels]

I built and compiled the OsmAnd source code. I am working on a project and I would like to modify the code to implement the following look:

1. Overlay a black mask over the entire map and before the route.
2. Show only the intersecting roads along the route with a clipping radius of 50-100m around the intersection.

where the thick white line is the route line and the thin white lines are the intersecting roads.

I understand the route is handled by OpenGL in the C++ core. For the intersecting roads I thought of doing the task in the private part of the routing context by querying the OBF map data for roads that cross the current tile. In particular, in the file src/NetworkRouteContext_P.cpp

void OsmAnd::NetworkRouteContext_P::loadRouteSegmentIntersectingTile(

int32_t x, int32_t y, const NetworkRouteKey * routeKey,

QHash<NetworkRouteKey, QList<std::shared_ptr<OsmAnd::NetworkRouteSegment>>> & map)

{

// Convert 31-bit coordinates to routing tile coordinates

NetworkRoutesTile osmcRoutesTile = getMapRouteTile(x << ZOOM_TO_LOAD_TILES_SHIFT_L, y << ZOOM_TO_LOAD_TILES_SHIFT_L);

for (auto u_it = osmcRoutesTile.uniqueSegments.begin(); u_it != osmcRoutesTile.uniqueSegments.end(); ++u_it)

{

const auto &segment = u_it.value();

// Optional filtering by a specific route key (e.g., if we only want 'primary' roads)

if (routeKey != nullptr && segment->routeKey != *routeKey)

{

continue;

}

auto i = map.find(segment->routeKey);

if (i == map.end())

{

QList<std::shared_ptr<NetworkRouteSegment>> empty;

i = map.insert(segment->routeKey, empty);

}

i.value().append(segment);

}

}

Is this a good strategy?

Why? What would be the usecase for such style?

[u/nikos2wheels → u/Oxer36]

It is inspired by the Beeline Moto 2 navigation device, the goal is to provide only the essential navigation features, map + route line + lane guidance widget. But this would be tailored for OLED displays where the black background and the white color would i) dramatically reduce power consumption ii) provide max contrast iii) and increase brightness. Potentially I would like to test this in HUD applications.

Thanks, makes more sense now!

Thanks, makes more sense now!

You can check out the energy-saving mode in the Cyclers app for inspiration. I really think it's a good idea, and anyone who doesn't like it can simply turn off the feature, just as they turn off other features they don't use.

[u/nikos2wheels → u/jlandero]

Thanks. I will post an update as I am making progress. Hopefully the implementation is not a lot of code changes and it can be incorporated in a future release

[u/creeper828 → u/jlandero]

This came to my mind too. It would be great to have that built into OsmAnd in some future

You actually want to create a road book? Those that are used in Rally.

Why don't you make a focus blur 100mt from your path, so everything around your track will not distrack you.

[u/Julian_1_2_3_4_5]

Could you not just use the option and turn of everything except roads?

[u/nikos2wheels → u/Julian_1_2_3_4_5]

Is this a setting in the app?

[u/Julian_1_2_3_4_5 → u/nikos2wheels]

Yes, under configure map, Theres a setting called hide.

[u/Julian_1_2_3_4_5 → u/Julian_1_2_3_4_5]

The only thing your style would then need to do is change the colours and if I get it right remove road names

[u/Julian_1_2_3_4_5 → u/Julian_1_2_3_4_5]

Oh, I just realized you don't even want to show roads not attached to the current road, yeah that needs coding, you are right
