Getting an orthoscopic view. #155

Hi,

First! Amazing job, thank you very much for getting us past the issues with unresponsive Java applets. I am wondering if it's possible to have an orthoscopic view option to remove the effects of perspective. This is very useful in viewing symmetrical objects around a helical axis, such as a fiber-model double strand of DNA or RNA.

Excellent job, and thanks!

Hi,

I'm glad you enjoy it!

Unfortunately, there is no support for orthographic projections in PV. The assumption that the scene is rendered using a perspective projection is spread all over the place, so it's not going to be a small change. I'll put it on my todo list :).

Best, Marco
