      Edit: 58 downloads and zero bugs? Hard to believe.

      Mac folks: any problems?

        This looks really great!

        Works fine on my Mac so far.
        Can you tell me about imputing the aspect ratio? i use sketchup to design tv sets so 16:9.
        Also does the statistics window always disappear behind the main skp window? so we have to re-size our windows when its opened?

        Is it possible with this plugin to show a true camera zoom from a certain location? so i place my camera i can show what it looks like from this position and and THEN from that position what a zoom looks like?

          Sorry to be so long. Somehow I missed your post.

          On my PC, my stats window pops up in front of SketchUp. Stays in front until I click the SketchUp window.

          For zoom, use two scenes. Use the Cam Stats plugin to set both scenes' cameras to identical eye, target and up values, but different field of view values. The SketchUp animation should give you a proper zoom.

If you could show things that were arbitrarily near or arbitrarily far, the math would require too many decimal places (or bits in the CPU).

              Need to open it modal on the Mac to make it stay on top. There is not a true modal WebDialog on a Mac as there is on Windows.

                I changed it to "show_modal" but it turned the friendly little guy into a huge pain. Almost useless. Certainly no fun.

                Mac users: edit the code. It's ...Plugins/camera_stats/camera_stats.rb. Change the line at the bottom that now reads "wd.show()" to "wd.show_modal()". Is that better?

                    very good idea about the camera 'zoom'. I'll test your code for the mac users when i have the chance.... Work!!!

                      Thanks, Martin. Another in a long line of very handy plugins! 😄

                      Just a couple of bugs to report, and one feature request:

                      First, I'm running XP SP3, SU 7.1.6860 (free version), and my IE is version 8.0.6001.18702. It seems to have problems when I use it, (which is rarely 😛 ) so it could be IE's fault, not yours... Anyway, I get the JavaScript error dialog shown in the attached image when I start the plugin (that is, when I open the window, not when SU starts).

                      Also, the "close" button on the Camera Stats window doesn't do anything (possibly related to the JavaScript error?).

                      Finally, the feature request:

                      It would be very handy if I could "pan" the camera left and right, relative to the viewport, by a specified value. For example, if I panned it right by about 2.5", it would be like I closed my left eye and opened my right (do you see where I'm going with this? 😉 ). I know (for me, anyway) the math would be pretty rough, but if you have the time, (you obviously have the grey-matter 😉 ) I would use this feature ALL OF THE TIME! 😄

                      Anyway, thanks again for the cool plugin!

                      EDIT: I just had another look at the Camera object API, and I think I know how to do this... Take the cross product of Camera#up and Camera#direction, use the resulting vector (or its negative) to transform Camera#target and Camera#eye, and use Camera#set to put it all back together. Am I close?

                      EDIT 2: ☀ Success! After just a bit of tinkering, I got it working! 😮 😲 😄

                      It's pretty much as I said above, but I had to experiment to find out how the API wants things done (plus I was a bit rusty at Ruby 😳)

                      I'm going to clean this up and make a new thread for it, just in case someone can use it, but here it is if you, Martin, want to incorporate it (not that you need my amateurish code 😉 ) or if someone wants to see what I'm blathering about 😉.

                            Looks like target = make_arr( val )wd.show should be
                            target = make_arr( val ) wd.show

                              There's a whole chunk of code lines between the two...
                              Did you do the edit in a plain-text editor like Notepad.exe ? [or MAC equivalent - perhaps BBedit??]
                              If you used a wordprocessor then it's added formating and messed up.
                              Start again with a new file download... 😕

                                what do the three values of the "up" field represent?

                                    This is a good plugin but it appears to work in inches only.
                                    I've positioning a cámera at 2.00 meters height and Camera_Stats reports 78.74 units to Z eye and target coordinates.
                                    It's possible ad all of the other units options (feet, milimeters, centimeters and meters) to plugin?
                                    I don't know how to do due to my poor knowledge to ruby.
                                    Thanks in advance.

                                      Eye and Target are Point3d x/y/z values in base-units [inches], Up and Direction are Vector3d x/y/z values.
                                      To make them into say 'mm' edit the main .rb file in the subfolder using Notepad.exe or a similar plain-text editor...
                                      Find the line that includes the text:
                                      ... $cam.eye().x() ...
                                      there are x/y/z versions for each of the 4 'types' of $cam methods... between lines #29 and #44 - 12 in all to change...
                                      Add to each as follows:
                                      ... $cam.eye().x()**.to_m** ...
                                      etc
                                      The additional ' .to_m' converts the passed value from inches into 'm'
                                      There are other converters too - ' .to_mm', ' .to_cm', ' .to_ft' etc ...
                                      So now at least you can convert your report to your desired units...

                                          Thanks very much for the great plugin. I'm hoping to use it to show different variations of a product all next to each other within the same model. I'm trying to set a camera position in scene 1 to show product alt 1, slide the camera position along the x-axis for scene 2 to show the same view of alt 2, slide again for scene 3, etc.

                                          After making the changes in the script suggested to luismoreno the camera position is shown in millimeters, but when I enter a new x value, the camera position moves much more than I specified and all the values change not just the x value. I know nothing about writing script so I'm sure there's something I'm doing wrong ^^.

                                          Thanks in advance for any suggestions!

                                            Should have included this in my original question....After checking some more, it looks like the plugin is giving the camera location information in millimeters after changing the ruby script as TIG suggested. However, if you try to input new coordinates based on millimeters, the plugin calculates them as if they are inches. That would explain why entering an x value of 5000 and pressing Send Data gives a camera position with an x value of 127000. 5000 inches = 127000 mm. When I changed the models units to work in inches the plugin was great.

                                            Unfortunately anything beyond "find x and change it to y" gets out of my ruby script writing ability. This is a really valuable plugin and any suggestions on making it possible for those of us working in the metric system to use it would be much appreciated.

                                            Again, thanks very much in advance.
