Additional 2d Drawing Commands

[Einlander]

I would like something like Context::DrawPoly( {table of Vec2()} )

 

While doing the 2d drawing, I found that using a scanline fill will IMMENSELY cripple the engine. if you scan-line draw (line by line) 3 squares on screen, you can see an fps drop from 200fps down to 40. and about 7fps if you use debug.

 

This would help reduce the amount of code needed for gui libraries, and help raise the fps count.

Not sure if I follow... Are taking about filled rectangles? Its already possible with Context::DrawRect(int x, int y, int width, int height, int style=0). 1 should draw a filled rect.

[Einlander]

I want a filled polygon. I want to feed it the points of a shape like a star, and have it fill it.

Polygon fill would be great it means I could port my gui to be rendered in 3d space easily!

This find and conversion from Einlander seems to work just fine in Leadwerks: http://www.leadwerks.com/werkspace/topic/11746-2d-polygon-fill/

 

 

Edit - I see what Einlander is referring to - as you draw multiples it will drop the framerate significantly, but maybe not surprising as there are multiple loops occuring for each 'polyfillcontex' command. Granted if i wanted a star to be rendered i would just have an image drawn to a quad as it would be extremely cheap compared to any other method.
