[Interest] GL_QUADS and Android

[Nuno Santos]

Hi,

I had the following error when compiling a working project on Android:

error: 'GL_QUADS' was not declared in this scope
_geometry.setDrawingMode(GL_QUADS);

Do I need any special include for this?

Regards,

Nuno

Hello,

Quads are not supported in OpenGL ES. Hence the lack of the symbol. Draw triangles (or triangle strips) instead.

Cheers,
Laszlo

QG_QUADS don't exist on embedded OpenGL: the top 3 Google hits about "OpenGL ES and GL_QUADS" tell you all you need to know:
