In a Orthografic perspective:
How keep always visible a polygon face when the end of the face is out of Ortho viewing volume, and this face is perpendicular to the viewer.

I need Depht_test Enable to keep the depth of the face...

Sameone?

can you draw what you want ?
;-)

Sorry:
this face is parallel to the viewer.....
I gona try draw...

The Z-near is down to New-ZNear and with this new ortho view volume i can´t see the polygon face (the begin and the end of this face is now out off the ortho volume clipping planes)....

If your polygon is futher away than the far clipping plane, it won't be drawn. There's no getting around that. You'll need to move the far clipping plane further out to be able to see it.

Adding new polygon 1(base).... and moving the Z-Far .....
In this situation, i can´t see the original polygon face too... anything to resolve this?
