Minimap generation enhancement

[jimmsta]

Currently, minimaps are generated via a point-cloud of an ADT. The resulting image is very odd looking, and not quite blizz-like. I know that that the application is already able to render appropriate overhead views, so generation of a more proper-looking minimap should be possible.

Take the baked textures function and use it to 'bake' a set of minimap textures instead of using the point map. The downside is the lack of models/wmo's, which I assume will one day be a part of the 3d view functionality.

WMO/M2s on the minimaps are definitely planned and is already a WIP.

It would be useful to somehow find out how Blizzard generates these. I'm currently doing exactly the same texture baking for minimaps that I do for the baked texture exports for ADTs but they just look really crap at lower res. My current guess is that they take a somewhat higher res capture of the area and then downsample it somehow. I think there have been applications in the past that rendered minimaps (notable noggit and cromon's tool) and I'm not sure how they did it exactly. Might be worth asking around.

I'll see if I can take another look at this hopefully before BfA drops.

I suspect that they apply some sort of anisotrophic filter to the textures prior to down-scaling. For instance, when using your 3d tile viewer, the textures look very pixelated from far away. I think if you applied some sort of filter to the textures, it would be closer to blizz-like. I'll have to take a look at how noggit does it, as it seems most correct. Cromon's tool had the shadows going the wrong direction, and no source was provided for the tool.
