Lately we have been working on cleaning up the XS name spaces of SDL perl. After some bumps and falls we came up with a separated Rect module. Rect is one of the most simple C struct as shown below.



Using the awesome perlobject.map as a reference I was able to create a blessed perl object in XS. So now SDL::Rect->new(...) gave us a blessed reference ready to go. And as an icing it would destroy itself properly no matter where it was used. But once I brought it into our existing code base, garu pointed out the extending it was a little bit of a mess. So far to extend Rect we have to something like below. Any comment or advice would be much appreciated.





Have at it I am a big boy. You can grab the code like this.
Only If you don't already have a local git repo:

mkdir SDL
cd SDL
git init .

Then do this or skip to this if you already have a local git repo
git pull git://github.com/kthakore/SDL_perl.git experimental

+Perl+SDL 3D Rendering +

+
+Recently we have done a lot of work on the next release of SDL Perl. But it all pays off when I see users do cool things as one of the users has done below. Talon^++! This project is a great example for people wanting to learn 3D from scratch.

This was a project to test how well Perl+SDL performs and does not use OpenGL at all. This is all perl and SDL, with the help of libsdl_gfx for SDL::GFX::Primitives. Texture mapping doesn't use SDL::GFX::Primitives because textured_polygon just takes a surface, tiles it, and clips out the polygon, which doesn't look 3D at all.
+
+Below are some screen shots of this little toy in action. If you'd like to try it yourself, you can download the entire project here. You can rotate the objects with the mouse, or keyboard arrows. Also press shift to toggle shading and space to switch objects.
+
+NOTE: the project is compressed in the .tgz format, if you are a windows user, you may need a tool like 7zip to extract the contents.
