Hi,

Is there an easy way to know the ratio of screen pixels and unit length based on the current projection and modelview matrices (i.e. how many pixels in a unit lenght, say .01)? Thanks for your help.

Well it depends on what you call easy

I’m sorry. Then can you give me a clue about how to get the ratio? Thanks.
