      Do you have any examples that will help me understand what distance based falloff is?

        Something about the fog settings certainly make it difficult for me to use. I'll grant that. But what could be done? Usually get what I need eventually.

        I would like to see what you mean visually if possible.

          I don't use fog much but I've thought it would be interesting to be able to define where the fall-off occurs using a graphical slider right on the ground plane. Probably not possible but it would be cool.

            It may be possible, since there appears to be some RenderingOptions methods in the API for this matter.

            I have never experimented with these, but one can extract this information:
            (I persume on can also set these attributes.)

            FogColor
            FogDensity
            FogEnd
            FogStart
            FogType
            FogUseBkColor
            ForegroundColor

            So using a graphical slider right on the ground plane like Dave R demonstrates could be a good solution. One could use GL rendered objects for that.
            There already are some fance gadgets in this fashion made. Look at some of Fredos Tools and Aerilius GL sliders and gadgets.

            It's an interesting project, but I don't have any time left over for this kind of thing. Maybe Renderiza ? πŸ˜„

              Hi,

              I will be happy to give it a try! πŸ’š

              The example that Dave R posted is very helpful to understand the end goal but if anyone have a particular idea please share it so we can make the best plugin possible.

              Thanks,
              Renderiza

                I did some looking around an found this post in which thomthom makes a list of what seems all the rendering_options... http://sketchucation.com/forums/viewtopic.php?f=323&p=271960

                For Example:

                Sketchup.active_model.rendering_options["DisplayFog"] = true

                Sketchup.active_model.rendering_options["FogStartDist"] = 1.0

                Sketchup.active_model.rendering_options["FogEndDist"] = 15000.0

                Note: Just in case you are lost in how to use the lines of code you see above, here is a list of some of the best Ruby Consoles for SketchUp... http://renderizastudio.blogspot.com/2013/06/top-ruby-consoles-for-sketchup.html

                  Here are some interesting finds...

                  Fog Distance -what does it refer to? by thomthom - http://sketchucation.com/forums/viewtopic.php?f=180&p=219538

                  The above is a discussion that have me worried the plugin we wanted to create is not possible. This distance value of the fog is always tied to the camera position so it is not a fixed value that can be easily attach to a marker on the floor like we want it to.

                  Maybe it could be done but I just don't know how at the moment. 😒


                  The following Rendering Options methods are a mystery to me!

                  • DisplayFogEdges

                  • FogDensity

                  • FogType

                  Maybe the SketchUp team was on to something they never finished. πŸ˜•


                  Anyways I will keep the search, wish me luck! πŸ‘

                    A Fog plugin would be very cool. I've tried fog a few times and never could get it to go where I wanted to. Best of luck Renderiza.

                      so i hope lives thats good. πŸ˜„

                        Ah bummer. Not as straightforward to do then..
                        Looks like there have been some pre attempts at making a plugin like this.

                        I have never dealt with fog so aint got a clue how it works.

                        Looks like there are some hints from TIG dealing with raytests and camera positions, etc in the links. Thomthom where on to something there as well.
                        Maybe that could help. Hope you manage to find something, Renderiza.

                          The camera position in relation to the markers on floor is something to be explored indeed but its going to be a mess trying to have formula that can give you the right value for fog. πŸ˜•


                          Depth of Field
                          with SkethcUP and Photoshop

                          Here is little experiment using Fog and the style options for making an alpha type image that I could use in Photoshop to make depth of field.

                          Alpha 1 (from SketchUp)

                          http://s21.postimg.org/h2d1wndtz/image.jpg

                          This is an exported image from SketchUp which was made to look like that using Styles options to modify fog color and few other parameters. This output image will then serve me as alpha channel to apply lens blur in Photoshop.

                          Original (from SketchUp)

                          http://s16.postimg.org/50848wuj9/image.jpg

                          Result (from Photoshop)

                          http://s3.postimg.org/bwdsy5xib/image.jpg

                          This is how it will look with depth of field applied, please keep in mind that you have full control of the amount and you can even invert it so that the blur area is the front. Apart from the blur effect I also did an inner shadow type of effect just in case anyone wanted to know.

                          Maybe I will make a tutorial so that it becomes more clear how to do this.

                          Thanks,
                          Renderiza
