Thanks, looks good!

Java / SFMLNativeDrawer.MAX_VERTICES
« on: October 14, 2013, 09:48:46 pm »
I was playing around with JSFML (nice work btw), and was trying to draw a grid of quads (in a vertex array) to the screen.  The idea was to be a virtual terminal, where each quad's texture coordinates would index into the a font's texture using glyph texture-bounds.

Unfortunately, I can't draw very many quads due (from what I can tell) to the SFMLNativeDrawer.MAX_VERTICES limit of 1024.  I get an IndexOutOfBoundsException and the stack trace leads me there.

For example, about 12600 quads of 17x17 (size determined by font measurement) fit a 1280*720 display.  That's about 50k vertices.

That seems like a lot I guess; maybe there's a better way to do this.  I haven't tried RectangleShapes, but I imagine 12k draw calls is a rather bad idea.  Maybe I can use jogl/lwjgl?  I'm new to Java so I don't know the lay of the land yet.


Woops.  The example was off.  For 17x17, that's 3150 quads resulting in 12600 verts.  Still over the limit.  :P

Graphics / Glyph background colors

I'm writing a roguelike with a pseudo-terminal appearance (in SFML.net).  I'm drawing Glyphs in a grid layout, but the only obvious way I noticed to apply a per-Glyph background color was to draw a RectangleShape behind it.

Is this sub-optimal and if so, is there a better way?
