PureBasic Forums - English

Here are a new challenge for PB:
OpenGL vs PureBasic

Comparing:
FPS and CPU consumption

The test it like this one (but without random stuffs):
http://www.purebasic.fr/english/viewtopic.php?t=21474


Rules:
Source:
blimp4.bmp
Events:
LMB: + 50 sprites
RMB: - 50 sprites

All sprites have to be shown on the screen.
All sprites have another size: Orginal size / 100 * n (n is counting 1...50)
All sprites are rotating
All sprites are moving: but only on the screen (not out of screen)

@pjay is informed and will put his adapt OpenGL version here.
(But I have seen this version and I can tell you: I LIKE PB)


Here the PureBasic version:
OpenGLvsPB.zip

I got 800 on screen in 65 frames a sec
before it started to drop on a radeon 9800 pro.

very good

Regards
Kevin

How was the CPU consumption?

I have an xp 1800

it seems to be on 2% with 800 sprites, strange i guess the gfx card is doing all the work.

I double checked it and it remains the same at 2%

Sorry, but you can't compare PureBasic with OpenGL, as PureBasic is a Engine and OpenGL is a renderer. And since PB 4 you have the OpenGL subsystem which doesn't work very well.

For comparison, here's the OpenGL version.

File:1->PBlimp3b.rar


Press 'B' whilst running to change from edited sprite to original & bi-linear original.

Crashes Are you sure you know how to use OpenGL?

I made this fault in my early years, too, until I got a computer with a low gfx card and I can work now for lower end systems, not only the higher ones. The higher ones don't crash anymore and are more error-tollerant. That's why everyone should work on lower ends.

Copy the OpenGL version into the folder of the PB version.
The RAR file has not the blimp4.bmp in it

Now it runs, but doesn't show anything, just a blue screen. No FPS and nothing.

Yes you are right. (He was on a hurry)

Sorry, but yes I can!
And no I did not using the PB 4.0 OpenGL subsystem.

Can someone explain me more exactly what "Comparison between PureBasic and OpenGL" means? I don't understand it ... PureBasic has nothing to do with OpenGL, you can just control it in PureBasic.

I see you are a german man.

Here we comparing:

1) OpenGL nativ function called with PB 3.94
2) PB4.0 Sprite3D functions

Is it this what you want to read?
