Download: [...] 
the demonstration have I on wish prepares.
The application benötig of OpenGL The permit on the VSync the Bildschirmes Waiting To can.
is these option not Anwendungsgesteuert set then becomes a Error Message outputted.
The code is messy and only fix gepinselt - it went only therefore To show the on able Systemen loosly 60fps possible are.

Abbing | | Hm, but is it with this method possible, each Hintergrundsbilder To manipulating? One circa with this Bespiel To stay: the itself z.B. the head the cat turn can? |

|
| | to that a is a Echtzeitmanipulation of Textures self-evident dank OpenGL possible, to that second is z.B. turn circa 3 Achsen at all no trouble - too a Abfolge of Textures (animated) is simply To release as well as the barge of Textures ineinander. |

The code is messy and only fix gepinselt - it went only therefore To show the on able Systemen loosly 60fps possible are.
The code is without The Inc not run and shows therefore too nothing. |

|
| Yes, unfortunately, but lauffähige Codes are well not my thing.
thatswhy stayed I rather with the lauffähigen Exe - rockt More. (and goes too without inc?)
The abgebildete code is it which in the Exe agiert, therefore have I the code posted - which itself you simply not show wants. 
think you whom code simply lane. |

Abbing | The engineering with the transformed TGA-Images is eh not really efficient. once the Blendung yet on another place needed becomes, fail these method.
its too no pure XProfan-Solution, How angekündigt, separate almost only API. Sogesehen are too XPIA-Codes pure XProfan-Solutions, because LONG even one XProfan-commands is.
VSync-availability only abzufragen is ditto not optimal. rather is it, it zuzuschalten. if not yet happen. |

your assumption is wrong, I use no TGA. the stature is 4 byte per Pixel without Header. from the Filesize yields the dissolution.
The Blendung is additionally too individually gestaltbar.
its too no pure XProfan-Solution, How angekündigt, separate almost only API. Sogesehen are too XPIA-Codes pure XProfan-Solutions, because LONG even one XProfan-commands is.
its a pure XProfan-Solution.
VSync-availability only abzufragen is ditto not optimal. rather is it, it zuzuschalten. if not yet happen.
too wrong, the code setting VSync and gives whom success back. |

Yes, You uses one own - unkomprimiertes stature: RGBA. an Solution for people, The The TGA-method not utilize would. These engineering becomes with NeHe declared (Lesson 32 faith I). |

| One code for the Reading TGA as OGL-Texture have I here already posted. ;)
I use the stature purposely z.B. to that testing. |

Abbing | | is too no code engineering. I yourself likes TGA neither. and PNG with mask is unfortunately not so simply To manage. |
|

|
|
| The oglhelper.inc has pieces The yet in the building are, therefore have I tappt im dunkeln not angehangen.
The here required functions herausfitzeln held I do not for meaningfully.
If the oglhelper in all sharing useable is it can eachone use. |
