Hi,<br> I've got it,<br> [GEMglDrawBuffer] defined with [GLdefine GL_FRONT] and connected to [GEMglClear] does single buffering.<br> <br> http://www.talisman.org/opengl-1.1/Reference/glDrawBuffer.html<br> <br> If you don't find it I will send an attached patch...<br><br> patco<br> <br><b><i>josephgray@grauwald.com</i></b> a écrit :<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> tried this also, didn't work in my patch.<br><br>Interestingly enough the patch in<br>GEM examples (PixDataSimple.pd) does leave<br>pixels behind that have not been drawn over<br><br>sending gemwin the "buffer 2" message does indeed<br>clear the old pixels though<br><br><br><br>><br>> if send buffer 1 to gemwin don´t draw anything.<br>> I want that when render a frame the previous frame<br>> don´t clear...still drawed on back of screen,and this<br>> way successively...<br>><br>> in openGL without the
command glClear this works.<br>> but in GEM i don´t know how desactivate glCLear...<br>> that is my question.<br>><br>> thank you.<br>><br>> --- chris clepper <cgc @humboldtblvd.com=""> escribió:<br>><br>>> You want single buffer rendering?
