Here's a patch that shows a top and perspective view of a gridshape displayed in two separate jitter windows. You can click in the top view on the gridshape and move it around and it will correspondingly move in the perspective window. My question is: is there some way to display both render contexts in the same window, similar to Wes' patch in the thread below?

I've found a few posts regarding displaying one render context in two windows, but haven't found anything on the opposite. Any advice would be great. Thanks.

Not two contexts, but two viewports in one window, yes. You can use 

sketch and gluperspective, and glviewport to do this.

glmatrixmode projection, glloadidentity, gluperspective whatever 

whatever., glviewport whatver whatever, then render your shiz.

search the list , I think I posted a patch with it working.

however opengl does allow two contexts to share one drawable(ie. window) so...

i would also like to know if this is possible with jitter.

seems like the it's setup to be 1 context per window.

i think probably not.

maybe with the increasingly popular lua?


Just posted to the wrong thread by mistake - was at least able to erase the message below. Sorry. Here it is in the right place:

Ok, thanks Vade. I'm getting there with it. Sending the following to gl.sketch:

reset, glenable scissor_test, glmatrixmode modelview, glviewport 0 0 200 200, glscissor 0 0 200 200, glloadidentity, glscale 1. 0.5 1., glrotate 0. 0. 0. 0., moveto 0 0 -5, glclear GL_COLOR_BUFFER_BIT, drawobject object 0, glviewport 200 0 200 200, glscissor 200 0 200 200, glloadidentity, glscale 1. 0.5 1., moveto 0 0 -5, glrotate 0. 0. 0. 0., glclear GL_COLOR_BUFFER_BIT, drawobject object2 0, glflush

I still can't figure out how to change my camera location so that each viewport is looking at the object from a different angle. Any suggestions?

Here's the patch (modified from elsewhere):

reset, glenable scissor_test, glmatrixmode modelview, glviewport 0 0 200 200, glscissor 0 0 200 200, glloadidentity, glscale 1. 0.5 1., glrotate 0. 0. 0. 0., moveto 0 0 -5, glclear GL_COLOR_BUFFER_BIT, drawobject object 0, glviewport 200 0 200 200, glscissor 200 0 200 200, glloadidentity, glscale 1. 0.5 1., moveto 3 0 -3, glrotate 45. 0. 1. 0., glclear GL_COLOR_BUFFER_BIT, drawobject object 0, glflush

Yeah, I ended up doing something similar to that. Here it is, although if you compare it with the first patch I posted, you'll notice that the mouse control is not right yet. Haven't had time to fool around with it.

2 render contexts, 1 window?
