-Migrating Sol's Tutorial of SDL to SDL_Perl +Perl+SDL 3D Rendering

If I have seen further it is only by standing on the shoulders of giants. --Newton



Sol's Tutorials


When I was struggling with SDL C a while ago, someone recommended Sol's Tutorial to me. It had not only help me understand video in SDL, but I believe my code has improved using Sol's code style. I would like to pass these along to fellow SDL_Perl users too. So here is the Ch 02 code of Sol's Tutorial in SDL_Perl. It will be getting more and more Perly as our team hacks on it. There is more to come!


To use this code you need the new Redesigned SDL_Perl Library


Getting SDL Dependencies


Only If you are on Linux (debian/ubuntu) you need the following dependencies:

$ sudo apt-get install libsdl-net1.2-dev libsdl-mixer1.2-dev libsmpeg-dev libsdl1.2-dev libsdl-image1.2-dev libsdl-ttf2.0-dev

On Windows we recommend using Strawberry Perl. It comes with SDL-1.2.13 header files and libs included.

Both Windows and Linux needs to install Alien::SDL

$ cpan Alien::SDL
** Add sudo to this for Linux

Getting Bleeding SDL


The bleeding SDL is on github. Click download on this site .

Extract it and cd into the folder run 
$ cpan .
** The dot is needed
** in Linux you may need to do sudo

Then you can run this script by doing

$ perl examples/sols/ch02.pl
\ No newline at end of file +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.
