Me and my friend are designing a birds-eye view pen and pencil RTS. Before using irrlicht I used my own written engine, there is nothing wrong with it but this time around I'm going to need a lot more features then I'm willing to write.
The main question I have for this, is what would be the best way to efficiently draw a flat terrian and a mass amount of units? The terrain isn't going to have a whole lot of depth, but it will be quite large. The user is told he is drawing on a sheet of paper, so the paper will have things like hills and rivers that are drawn on top. I'm unsure as to if the terrain needs to be a grid, but it would be the easiest way to implement it.
If this is the case, how would I go about loading my own custom generated mesh in irrlicht and use an octtree node to display it?
Thanks.
