Package viewer :: Module sim_viewer

Module sim_viewer

A viewer for the MoSP simulator.

It uses a socket to receive geometric objects from the simulation and draws these onto a layer of OpenStreetMap-map-tiles.

To Do:

draw triangles!!!
Zoom fit to BBox (Hmm...maybe trial and error is possible...might be tricky...)
Zoom to double click position (double clicks should be easy, accurate centering on coordinates is not supportet right now...could be hard)

TILE_SIZE

The size of one OSM-tile in pixels. This is constant as long as OSM does not change.

Value:

MESSAGE_TYPES

Supported message types for lookup after receiving an identifier.

Value:

{'\x00': 'coords', '\x01': 'point', '\x02': 'rectangle', '\x03': 'circ
le', '\x04': 'triangle', '\x05': 'text', '\x06': 'heatmap', '\x07': 'd
irect-text', '\xFD': 'delete', '\xFE': 'draw', '\xFF': 'simulation_end
ed',}

MESSAGE_SIZE

The precalculated size of commonly used structs.

Value:

{'\x00': struct.calcsize('!dd'), '\x01': struct.calcsize('!iddi4dd'), 
'\x02': struct.calcsize('!i4di?4dd'), '\x03': struct.calcsize('!iddi?4
dd'), '\x04': struct.calcsize('!i2d2d2d?4dd'), '\x05': struct.calcsize
('!iddiii4did'), '\x06': struct.calcsize('!ddi4d'), '\x07': struct.cal
csize('!iiii4did'), '\xFD': struct.calcsize('!i'),}

ID_TYPE_PREFIX

These values will be added to the IDs of the respecting object. This is necessary to be able to differentiate between them after they are mixed together for faster calculations.

Value:

{'\x00': 0, '\x01': 0, '\x02': 100000, '\x03': 200000, '\x04': 300000,
 '\x05': 0,}
