AccuRender nXt

advanced rendering for AutoCAD

Working on a close relative of sub-surface scattering.  Looks like someone burnt dinner, but it's kind of interesting.

Perfect! 254 pliiiiiiiiiiz!!!
If this was allowed to run an extended period of time would the sunlight beams through the window resolve better to predominate better or would the fog/smoke effect be adherent with using this engine?
Sun streaks?
Very low density interior fog.
Can you adjust the size of the particles as well as the density?
I agree

They aren't discrete particles-- (or a true density for that matter. )  What appears to be particlulate is actually just remaining noise in the path tracer.  This one ran for a half hour-- it will get smoother (slowly).

 

What you're actually specifying with the algorithm I'm playing with is a probability per unit distance that a ray entering the medium will scatter, absorb, or pass through (neither scatter nor absorb.)

Backlit scene.  Coming along.
Same scene-- thicker fog.
Colored fog:
if it was possible to adjust the properties of the fog in the nXtImage editor, that would be marvellous - is it possible, Roy?
Nope.

"Great image as always. I would just blur the tree shadow on the lawn to match soft shadows on the building. Nice blending of cut-out greenery. Excellent job."

Railroad kitchen

"Very nice rendering Chris! The only thing that distracts me is the fruit bowl. It's too evidently pasted in PS.  Another thing (nothing to do with rendering) is the microwave above the stove. I would rather expect a cooker hood there."

trim and extension command

On AutoCad 2021.The trim and extension command works funny. I initiate the command then click the cutting edge (press entre) then click the lines I need to trim or extend.Now I initiate the command and as soon as I click the object selected trims or extend.  How can I correct this, it is really affecting my work?See More
