Magnifying Glass Scene
Posted: Sat Jul 10, 2010 12:39 am
Here's a scene for you to download and try... a magnifying glass.
It uses 96 segments in the arc, so that it is smooth glass.
It uses the flint glass template in "Templates>Realistic Glass>Flint"
Render "Scene 5"
The magnifying glass was positioned and focused only by positioning it first parallel to the ground plane and hovering it very closely above the subject, then rendering with the "Easy 01 Prelim" setting,
Then it was moved up and over and slightly away from the subject toward the camera. Then a prelim rendered once again.
Then it was moved only a little bit more to "fine tune" the focus with perhaps 3-4 prelim renderings to check the position.
It was rendered with Easy 09 Interior progressive render setting to 100 passes and then stopped. But it looked fine after only 10 passes.
It also looks good with Easy High+ but actually takes longer to render on that setting than with Easy 09, due to all the fuzzy tracing of specular reflections on most materials and the light emitting surfaces used for the studio lighting.
Please try it for yourself.
The model is a rough estimation of a magnifying glass, not an actual true mathematical model.It uses 96 segments in the arc, so that it is smooth glass.
