Image Deformation in SFML

[Laurent]

It's an old code based on the SFML 1.6 renderer. The implementation would be totally different with SFML 2.

Oh, I can't read it for a few more days so I didn't know.
It's mindblowing to achieve this without vertices from 2.0

[Spidyy]

Someone really wanted to use the Stroke class, so I'm working on it to port it to SFML 2.0 and give it a few enhancements.

And regarding this, what would be the faster way to display dynamic mesh? Directly calling glVertex3, like the old renderer.AddVertex(), or using a vertex array we clear and rebuild each frame?

The 'clean' way would probably be to use a sf::VertexArray or use your own arrays of sf::Vertex, SFML will then pass that on to OpenGL, but if you really want to watch out for 'fast' as in performance, then the direct OpenGL calls might be faster.

[Laurent]

OpenGL (if used optimally) will always be faster than something which is a layer on top of OpenGL

... but SFML vertex arrays should be more than enough for that

If someone can't wait to get a 'working' copy of the class, I've rewritten the rendering part, but since I don't quite know on how to handle the class to get nice effects, I can't really test everything, anyways here you go.
You could for instance use to get to know the class a bit better and then once Spidyy will have finished the remake (with different function names and improvements ) you should definitely use his version.

I wasn't really that eager for it, but it is very well appreciated, I'll be able to give it a lot of use. Thanks.

I'll most likely will. I at least now have a bit more of understanding towards vertexes (openGL forces you to) so I'll be able to take far more from the code now than I would have before getting into it.
