3d overlap

i've noticed that 3d shapes that come too close to the viewer (i.e. are translated too far forward) begin to 'overlap' in space - the shapes are drawn flipped around both the x and y axes and move back away from the viewer.
seems like there may be some minimum value for translate, beyond which values move from positive to negative and are then redrawn flipped. does that make sense?

yep, this is a known issue. it actually happens when objects move behind where the camera point is. in terms of the geometry of the "problem", you can understand it by drawing an imaginary line from any point in front of the camera straight through the camera point, and out through the back. the straight line will show you where these "reflected" objects will show up.
also, i believe there might be some kind of auto-clipping planned for the future...

yep, clipping is coming for 57 or 58. carlos is currently holed up at ivrea and banging out code to fix this issue.
