Renders OpenStreetMap in ImGui window

ImOsmDemo

This is an application for demonstrate possibilities of ImOsmWidget. It is based on ImProject template.

ImOsmWidget is included as submodule in directory external/imosmwidget/.

In short I use ImGui with GLFW backend, ImPlot, CURL and STB libraries to display interactive map using tiles provided by OpenStreetMap.

Ubuntu dependencies

For ImGui with GLFW backend the following packages must be installed

libx11-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev freeglut3-dev

For ImOsmWidget libcurl needed

libcurl4-gnutls-dev

imosmdemo's Issues

MinGW64 and Windows

when compiling, the compiler will throw an error:
