hello list,
with GEM, is there an equivalent to Jitter's jit.lcd object?
jit.lcd lets you draw lines which stay permanently on the screen in 2d space, rather than as OpenGL objects, or what have you - it's more like moving a pen across a surface, you just draw a line and then forget about it.
thanks d
Single buffered GL contexts will do this. Send a buffer 1 to the gemwin before creating the window. Then bang the gemhead each frame (metro works well for this). Sending a bang to the gemwin will clear the window contents.

Is there also something in between? Like, IIRC, jit.lcd can optionally clear "objects" a certain time after they have been created. "bang" to gemwin always clears the whole screen.

Not really, but you can lay a rectangle over the whole scene and give it a tiny bit of opacity which will overwrite the contents of the buffer eventually. This is the way to fake motion blur using single buffering.

I think a negative render order number may be what you are after
[-1( | {gemhead] |
it puts the object in front of the 3D space, related to the gem-
window not the other objects and 'unaffected by viewpoint changes'
according to the gemhead helpfile

sorry that should be:
[set -1( | [gemhead] |

sorry that should be:
[set -1( | [gemhead] |
or simply [gemhead -1]
and be aware, that this does not work in single-buffered mode (where you have to trigger the [gemhead]s manually)
