Hello,

The question essentially is whether SFML will be hardware accellerated when compiled with SFML ES flag and using the 2D draw fuctons, scale, move, draw, animate sprites ...

Meaning I don't need to work with an OpenGLES context, indeed to work with SFML core functions (and not run through OpenGL emulation since the HW supports only GLES 1/2).

But I'll experiment with this as well though if someone already know clearly about that it'd help.

Thank you,

Jean-François

Hi,

Great news, it's a Beagleboard black with AM335x ti ARM based (v7) and SGX 530 graphic card which supports OpenGL ES 1 and 2.

Would SFML be accelerated ? At the moment it uses GL and the software emulation somehow, which works but it very slow (CPU emulation).

Thanks & regards,

Jean-François

Hi,
I was working on a beagle board project where some animations are done with SFML and it seems though working it was not performing fast. After discuss we understood that's probably due to the fact SFML uses OpenGL which is not accelerated and uses software emulation on this particular hardware.

Is there a way to build SFML differently so it uses other means to render than OpenGL ?
There is OpenGLES and otherwise Linux graphic libraries available.

Regards

Thanks I'll try it.

I remember from last time I tested this solution it was indeed kind of working.

Hello,

At the moment, I have an application that can launch sub-systems.

I sometimes need to instanciate a window have it invisible as its initial state.
At the moment I instanciate and immediatly set it invisible:

void setVisible (bool visible)

This makes it flash thus I'd prefer start it invisible.

Window / Opening windows hidden

« on: December 25, 2020, 01:23:15 pm »

Good day,

I'd like to open a render window in hidden mode, though I found out this is not currently implemented and requires dealing with openGl directly.

Am I right, is there a way I didn't see ?

Thank you,

Jean-François
