so all i do to add nodes to the minimap is:
MiniMapState state = app.getStateManager().getState(MiniMapState.class);
This is at the right bottom of the game screen. It shows my terrain and the “representers” of my little city.
what it looks like:
Yes i know, u will say, “Oh those boxes look ugly ^^” …
I used to render the original scene to the viewport and got a horrable decrease(But nice look ;)), so in this version the fps decrease is about(~1-2fps or a more comparable info 2million verts <-> 20k).
The 4 different squares are 4 terrainquads, which come from the TerrainGrid. They are genearted via a fractale terrain loader and a mix of different materials(Snow/Sand/Rocks,…). So what u see is the worlds terrain and in the right lower square a terrain where a city is showed.
To clarify this situation i add a screenshot of the full screen.
You normally see the transition between the quads as water, but the scale is removing my water ;).
Here is a similar scene with my old minimap way(Difference of having minimap off and on is 30fps and 790000vert<-> 3,2mio verts): Scene
