Use faster drawing for small tiles #4

Open msteiger opened 10 years ago

msteiger commented 10 years ago

Currently, drawImage() is used to draw individual tiles. Using drawLine(), fillRect() or maybe setting raster data directly should be a lot faster for tiles that are smaller than 2x2 pixels.

Or it may be that we should skip drawing tiles at 2x2 and 1x1 and go straight to the city-rendering-view

The cities renderer relies on two aspects: it uses the 2D (simplex noise) height map directly, which is a lot faster than creating actual chunks and extracting the height map from there.

Second, it uses an intermediate structure (the Brush) that just writes the block with the highest y value to a 2D array instead of creating chunks.

I think that both approaches are difficult to generalize and therefore won't work for other world generators. If that's ok, we can surely speed up the rendering a lot, but it will work for "Cities" worlds only. What do you think?

If you are willing to give it a try, that sounds good. Right now we don't have anything that works, right? So getting it to work with Cities worlds is a start.
