[NTG-context] MetaPost Question

2015-12-06 Thread Context NTG 
I am trying to graph a cylinder. Is there a way to draw a more elliptic
top/bottom. This one seems some flattened at the top and bottom. I would
like to hatch the mid elliptic that is collored grey now. Is there a way to
do this.

Thanks
Jeroen

Confirmed, it appears to work if you revert to the old loader in
font-lib.mkvi.

Please change your mailing name and address.


In order to draw 3D perspective diagrams in MetaPost,
you will need to transform 3D paths to a 2D projection.
There are many methods to accomplish this, and there are several MP
modules that have been written to address this issue.

One fairly simple and elegant approach is available from Urs Oswald:

The problem persisted with Courier New, not only Source Sans Pro (SSP).

The font file for Source Sans Pro came directly from the Google's font service.

The SSP (on my machine) works fine in Inkscape.

The exact same font was also working before the ConTeXt upgrade.


Confirmed, it appears to work if you revert to the old loader in
font-lib.mkvi.


i need a better example of what fails then as it works here
