I am able to render a curve by bevelling it.

However, for a scientific visualisation that I am working on, this doesn't render the way I wish it to. I would like the curve to render as a fixed width line irrespective of the distance from the camera.

Currently, I have to adjust the bevelling amount based on camera distance, and also play with rendering samples to get a smooth looking line.

Is there a cleaner approach that I am missing?

I am currently using the "cycles" renderer, but I am open to suggestions for any other renderer. Thanks!

Clarification: This is an animated visualisation. Hence, the distance from camera varies continuously. Here's an example video of what I am trying to do. The comet orbit is the curve I am worried about.


Question: .htaccess remove index.php sort of works, but not the first time after browser cache is cleared
Answer: On further investigation, it appears that this redirect is coming from inside that template. 

See the attached image



All of your header assets are being loaded just fine until something else triggers the redirect, in this example it happened after the server already responded to 15 gets from the generated page. What kind of addons does this template use? Try investigating that.

EDIT: To be clear, anchor tags are never even sent to the server. If it is the .htaccess setup, there is no way it's rewriting anything based on anchors.
