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......
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
