 hi Chris,
 
 i was looking at elmex's construder code recently, and noticed that the 
 passing of an SDL surface to OpenGL was done by dumping the SDL surface to a 
 BMP temp file (via File::Temp), then loading the BMP with OpenGL.
 
 obviously this solution is a little slower than others, but... it should 
 'just work' without much effort
 
 we could always use this lazy technique for initial testing, until a more 
 'correct' solution is sorted with SDL_Texture :)

 I'm glad to see the interest but most of the base work
 is still needing to be done as far as the OpenGL stuff.
 We need modern OpenGL support in POGL before a lot of
 the specific development can occur.
 
 However, one important piece that could be investigated
 is how we could make conversion between SDL2 objects
 and PDL objects work.  Ideally we could have a fast
 conversion to take a piddle and use it for an SDL2 surface
 or texture or whatever and similarly for the other direction.
 
 Currently, the approach used for SDL is to create the PDL
 object with the right sized data segment and then pass that
 to SDL to make a surface from that.  I'm not sure what would
 work for SDL2 stuff.

automated building/testing for SDL_Perl?

2013-08-11 Thread Mason James
hi All

I've recently learnt how to use the Travis [1] automated build system with 
github repos

its a pretty handy tool that detects errors in commits; and also builds/tests 
your codebase after any commit series is pushed, on multiple versions of perl 
even (currently 5.10 - 5.18) 


with some pretty small changes, I've managed to get both the SDL and Alien-SDL 
repos building/testing successfully with Travis [2][3]
(i plan on sorting the SDL2 and Alien-SDL2 repos soon)

so… is this something people are keen on using for SDL_Perl project?

adding texture scaling functionally to SDL2_perl

2013-08-09 Thread Mason James
hi sdl-devel

i am planning/researching about adding a small amount of SDL2_Perl code into my 
existing SDL_Perl app, for a framerate increase
i have one long-standingly slow bit of code in my app, that i would like to 
replace with SDL2 code

my slow code is a SDL::GFX::Rotozoom::surface() call. but SDL2 has 'hardware 
accelerated' stretching/scaling/zooming [1], yay!


i checked the SDL2 version of ./SDL2_rotozoom.c, and it is still using the 
current slow software method (no changes) 
but the good news is… there seems to be a preferred method to achieve this fast 
hardware scaling in SDL2

SDL2's SDL_RenderCopyEx() function [2] will scale a texture using a fast HW 
method, (but...i have not benchmarked my theory yet)


my plan is to attempt to add some missing SDL2 functionality to SDL2_Perl.
then swap my slow SDL::GFX::Rotozoom::surface() call, with the faster SDL2 
equivalent

so basically, i need to implement the 'test/testrendercopyex.c' demo [3], in 
SDL2_Perl, 
and add access to these missing SDL2 functions in SDL2_Perl...

SDL_LoadBMP(),
SDL_CreateTextureFromSurface(),
SDL_FreeSurface() 
SDL_RenderGetViewport()
SDL_CreateTexture()
SDL_SetRenderTarget()
SDL_RenderCopy()
SDL_RenderCopyEx(),
SDL_QueryTexture()



fyi: the testrendercopyex.c demo is nice and simple, it...

- loads a .bmp file to a surface
- converts the surface to a HW texture
- then randomly moves, rotates and scales that texture around the window, in a 
loop

i believe this demo is using the new hardware-accelerated scaling on a 
'texture' in SDL2
