new to GLSL coming from Processing v1.5.1 to 2.0b8...

in General Discussion • Other • 5 months ago

Hi,
I upgraded Processing from v1.5.1 to v2.0b8.
My application was not able to run now.
I give error in Processing windows giving me only this informations:
"processing cannot run because glsl shaders are not available"
I searched by Google but my experience on Processig was very poor for now.
How can I correct the throuble?
Many thanks to all.

In Processing 2.0, a new version of the OpenGL library replaces the one found in 1.x releases:

It requires a more recent version of OpenGL, which may cause problems on older hardware and/or out-of-date drivers

it is now part of the core (no need to use Import Library → OpenGL). This simplifies things (enormously), and brings better parity with other platforms like Android. This makes exported applications larger, but the benefits are worth it.

The new library is based on Andres Colubri's Android work (and his experiences developing the GLGraphics library). All the great things from Android have now been back-ported to the desktop version of Processing, so we have a super fast OpenGL library.

of course it's possible to adapt from 1.5 to 2.*
if it's just about shaders, shouldn't be so hard to do. post your code if you want specify help.
