Re: [udig-devel] Question #5 - The purpose of the RenderManager

Another question to be added to the FAQ as suggested in

----------
Just because I saw it in the uDig-Sources: There's a TODO in the
net.refractions.udig.project.internal.render.RenderManager that fits
right into this FAQ: What's the purpose of the RenderManager? Is it
the one that chooses which Renderer to use?
There are several requests for a better documentation around in the
RenderManager and the concerning classes...
Think I just managed to answer that in the other thread:
RendererManager processes an extension point where different sorts of
rendering "workflows" are described... it chooses the best one (by
looking at some metrics) and then uses it to draw onto a raster. As the
different renderers draw, it smushes all the rasters together onto the
screen.

PS.: Just getting an idea of how huge this project is, omg, respect...
The great part is that it works, and it lets us add new kinds of
services easily, and it lets us provided fast optimizations of things
like shapefiles, all without a) getting *really* complicated b) leaking
out into the "layer" api where it would get in the way of people writing
plug-ins to manipulate data.
I have a picture somewhere (part of the documentation done for OWS-3)
that I can share...
