This currently uses the software renderer and I'm still planning to change that.

Please consider using the Blackflux forum if you want to give feedback. I will probably not be able to check this thread regularly in the future.

Looks cool. I think the software renderer is actually a good solution for this...less hassle, works everywhere, no hardware dependencies and no fighting between OpenGL and the GUI over world domination.

Edit: And if it's too slow, there always the option to enable multi-threading for it: http://www.jpct.net/wiki/index.php/Multithreading#The_software_renderer_on_multiple_cores

aZen:
Thank you for the reply!

The software renderer is already multi-threaded. The problem is that the refresh rate goes down significantly when one expands the viewport (e.g. 2560x1440). I think the drawing onto the canvas is just taking too long.

Is there a way to improve that?

EgonOlsen:
How are you doing that drawing into the canvas?

aZen:
In reality it's more complicated, but the basic idea is:


--- Code: ---World world = ...;
FrameBuffer buffer = ...;

buffer.clear(BGCOLOR);
world.renderScene(buffer);
world.draw(buffer);
buffer.update();

Graphics2D igr = (Graphics2D) buffer.getGraphics();
[...] (draw on the igr)

Graphics2D gr = (Graphics2D) BufferedImage.getGraphics();
buffer.display(gr);

--- End code ---

I already did some profiling and most time is spend on draw(...) and update(), but not sure what exactly happens when the canvas enlarges, so I'll need to test that again.
