Re: [Pharo-dev] [ANN] Pompeii Volcanic Graphics, a mesh based 2D graphics API

[Esteban Lorenzano]

Vectorial Graphics are CPU intensive, and is arguably if it is a good solution 
for rendering IDEs. 
Using OpenGL 2D allows us to have another possibility, that will perform better 
in some scenarios. 

thanks Ronie for such a great work!

 OSWindow is too important for us :) 
 Now we need to move everything to use it but our plates were rather full.

 willing to try adding the backend for Bloc.

Yes, I’m just not aware how Cairo and Moz2D are rendering the things the we ask 
them to. That’s why I wanted more info :)

Re: [Pharo-dev] [ANN] Pompeii Volcanic Graphics, a mesh based 2D graphics API

[Tudor Girba]

The cool thing is that the rendering can happen on the GPU (through OpenGL), 
which is the fastest you can get for rendering .

So, the current renderings are not the point. The point is the possibilities 
that are open once we have access to rendering 2D through OpenGL.

Cheers,
Doru

Re: [Pharo-dev] [ANN] Pompeii Volcanic Graphics, a mesh based 2D graphics API

[Yuriy Tymchuk]

Hey guys, can someone explain me why this is cool? :)
Because the examples just have basic shapes with gradients & similar and AFAIK 
you could do that for a long time with Pharo and other technologies. Does 
Pompei mean that we can render complex graphics super fast? Is there an example 
for that?

Esteban is preparing the release of Pharo 60 but I'm quite sure that he
will integrate your PR for SDL20 and OSWindow.
OSWindow is too important for us :)

Re: [Pharo-dev] [ANN] Pompeii Volcanic Graphics, a mesh based 2D graphics API

[Tudor Girba]

Hi Ronie,

This is fascinating work!

We will definitely look at this to see what it would take to have it as a Bloc 
backend.

And thanks a lot for tackling the SDL2/OSWindow issue. We will test that as 
well.

Cheers,
Doru
