Objects appearing in the wrong places

Dear list,

I’m doing some stuff in mxj with jitter, basically I have a load of gridshapes each textured with different jpgs and I’m trying to draw lines between them. I draw the gridshapes by setting their automatic attribute to 0 and using the drawobject command with jit.gl.sketch. After I’ve drawn all the gridshapes I try and draw lines using linesegment, the problem is the lines and gridshapes don’t match up, I think somewhere along the way the geometry is getting messed up, I’ve tried putting a pushmatrix and popmatrix between each set of commands I send to jit.gl.sketch but no luck. Any ideas what could be screwing with my geometry? Right now the only solution I can think of is not use drawobject at all but try and do the whole thing with gl commands to sketch directly, but this is likely to fry my brain.

I have re written the mxj to draw textured quads using jit.gl.sketch, I’m drawing frames around each quad and lines linking each quad to each other, i specify the glcolor before drawing the frames and the lines but these colors aren’t used, colors from the textures are. how do I get gl to do what i want?

glpushattrib and glpopattrib have solved my problem, i hope this helps someone else someday
