Alexei.....

....I take Graphics Rendering to mean the process by which the Object is
generated either by means of hardware, software or both,... ....that is the
extent of my knowledge about it...

here is the message that Yves Klet sent me.....

Subject: Re: Speed of VectorPlot3D... What is Rendering?

I asked a question several weeks ago about speeding up 3D Graphics using
VectorPlot3D and Mouse Rotation....I never got a direct answer, however,
several persons (Yves and Alexei) posted answers for another question that
helped to solve mine......for my case and computer ..........

I set MaxRecursion->3 and in the Options Inspector under Graphics Options
I changed Graphics Rendering to HardwareDepthBuffer......

The increase in speed of rendering really surprized me....and the Graphics
object rotated almost instantly........MaxRecursion especially made a
difference....if I set it to ten it took forever....at 3 worked like a
charm....


thanks to Yves and Alexei......

Dear Community,

I wonder, what is Rendering?

First, how should this word be translated in the Mathematica context. I am
not English native speaker, and looked into a dictionary. A good one. It
returned me about 300 meanings of the word none of which I could really
correlate with the graphics operations.

I looked into help and find this:

"Rendering opens a submenu to control rendering operations."
and details do not help to understand what does it do.

It is like in one of Lem's stories: "Sepulkys are necessary to make
sepulation". "Sepulation is the process using sepulkys" (not sure that my
translation is equal to the original one, but the sense is there.

So, what the Rendering mean and what does it do?

Best regards, Alexei
