c# - Is there any open source wrapper around UnityEngine.GL namespace that would provide System.Drawing.Graphics alike intereface? -

-

i love see system.drawing.graphics methods drawpath(pen, path), translatetransform(dx, dy, order), scaletransform(sx, sy, order) wrapped around unityengine.gl (or @ least other opengl library create own port). there such wrapper/library?

assuming want draw on texture use in unity, here simpliest example using cairo build bitmap directely usable texturing opengl. wrapper mono.cairo

using system; using cairo;  namespace cairotests {     class program     {         static void main(string[] args)         {                         int height = 512;             int width = 512;             int stride = 4 * width;               int bmpsize = stride * height;             byte[] bmp = new byte[bmpsize];              using (imagesurface surf =                 new imagesurface(bmp, format.argb32, width, height, stride))             {                 using (context ctx = new context(surf))                 {                     ctx.setsourcergb(1, 0, 0);                     ctx.rectangle(10, 10, 100, 100);                     ctx.fill();                 }                 surf.flush();                 //surf.writetopng(@"c:/test.png");             }             //now have bmp filled, , may pass game engine texture                      }     } }

next step create egl context , try keep work on gpu, passing final texture bind existing one.
