I don't think this has been reported. If you pass the commands:'reset,

glmatrixmode modelview, glpushmatrix, drawmatrix myMatrix points,

to jit.gl.sketch the scene is rendered. However, if glloadidentity is added

to the command list the scene is not rendered, or at least is not visible:

'reset, glmatrixmode modelview, glpushmatrix, glloadidentity, drawmatrix

I don't think this has been reported.  If you pass the commands:'reset,
glmatrixmode modelview, glpushmatrix, drawmatrix myMatrix points,
glpopmatrix'
to jit.gl.sketch the scene is rendered. However, if glloadidentity is added
to the command list the scene is not rendered, or at least is not visible:
'reset, glmatrixmode modelview, glpushmatrix, glloadidentity, drawmatrix
myMatrix points, glpopmatrix'

I think in this case you're going to need to post a patch. I'm not

too surprised that you don't see anything with glloadidentity as I

don't see you modifying the modelview matrix after calling it.

I think in this case you're going to need to post a patch.  I'm not

In your patch you were rendering the cubes exactly at z=0 i.e. at the

location with the camera. This is what happens when you cal

glLoadIdentity() without offsetting in the Z direction.

Ooops! Of course. And I was neglecting that the camera position is also

part of the modelview matrix. Sorry Wes. I guess I need to get back to the

Fwd: bug with jit.gl.sketch and glloadidentity
