This post will be about work because my current task is really interesting

In details, the task is to optimize drawing in geo-coordinates. Now the geo-coordinates are converted into screen coordinates, and this is not very interesting.

I’m making special interfaces so that it is possible to draw using geo-coordinates: that is, it was necessary to decide what to draw, and then the screen coordinates when changing the projection will be recounted on the GPU.

This is already partially implemented for the synchronous version of openGL. And I'm working on implementing it in the asynchronous openGL version(it is necessary that you can change the drawing in the side thread, regardless of drawing) and the synchronous version for AGG(the graphics library for drawing on the processor when there is no GPU or openGL). Alongside, I translate several layers in our application on these interfaces.

I like this task because I have to think a lot, understand a lot of new things for me and read a lot of interesting (although sometimes bad) code.
