Hi folks,

today i've created my first dlang library ^_^ a binding to the OpenVG library standard. The referenced implementation is ShivaVG which allows to draw vector graphics within an OpenGL context (similar to cairo).
A small demo application is included, using derelict gl3 and glfw3

Could you please add an example using Devisualization.Window?
That way its one less external to D library that is a dependency.

Thx. I'll give it a try because it matches something i've started last week. I could use Cairo but a few years ago i've already gave up something similar because of the bad performances (Cairo is made and dedicated to inkscape, isn't it ?). Are OpenVG perfs better?
This lib is quite unknown btw.

I tried and failed so far, pls have a look here:

I think the reason for this is that vector graphics are mainly used for drawing userinterfaces and illustrations like pdf file, svg file, etc. Here performance isn't much of a problem so there isn't any need for change. Cairo is imho a quasi standard and didn't change much since long time.
Since I use OpenGL I recently looked into OpenVG and it has a really clean and easy to understand renderpipeline and api. Khronos created a specification for OpenVG, but there aren't many (open) implementations yet. Some mobilephone manufacturers have implementations for their devices, like nokia.

Since you are interested in performance i think going with any hardware accelerated vector graphics library should work out for you. ShivaVG or cairo with a opengl backend (there are lots of different backends)
