[Plugin] SU2POV for GSU6

Hi John,

I had assumed that was when the model was Set to Use Sun for Shading, but this happens as well when it is not set for Use Sun for Shading and also when the rendering setting of Lights is set for lights only. Is this what you intended?
I never noticed any difference with that checkbox ticked or not. Here is what the SU help says: "Click on the Use Sun for shading checkbox to shade the faces of your model based on the position of the sun. SketchUp uses standard shading that follows the camera when Use Sun for Shading is not enabled."
Not correct, at least by me: no standard shading that follows the camera. It makes no difference, that's why the script doesn't take care of it...@unknownuser said:
Is it a prescribed amount of minutes before the sunset time listed in the Shadows Dialog?
Almost. The script calculates the "slope" of the sun rays and when it is less or equal than 0 radians it considers that it is night time (sun rays slope is negative during the night because the sun is "behind" the ground). Between 0 and 0.2 radians the color of the sun light is slightly modified (at sunset or sunrise).
@unknownuser said:
In your documentation you show the Sun actually being rendered in the sky. How is this done, is it automatically placed (per SU's sun position) once the script is run the first time for a model?
This is done this way: the script evaluates the angle between camera direction and sun rays vector, and calculates wether the sun is in the field of view or not. When it is, the component "su2pov_sun" is inserted at the right place, then removed after the export is finished. The component uses a png image that goes from white to transparent to mix the sun with the sky color.

Thanks, Didier, for the feedback.
"..When it is, the component "su2pov_sun" is inserted at the right place, then removed after the export is finished. .."
Very clever programming.

+1!

Great plugin. Question. How does the plug in know what surface is glass for glass finish?
-
Hi,
If opacity is less than 100% the scripts considers this is a transparent material and applies a glass finish, if it is set in the rendering options.PS: i'll publish a 3.2. release soon with a basic material editor.

Hi Didier!
I have unzipped su2pov3 and installed su2pov_24_setup.exe. I've also been able to export to POV-Ray and I'm a happy user of that part already now. But installing the 2.4 version gave me the su2pov buttons also. My problem is that I get an error message using the buttons. The program can't find the components (su2pov_spotlights.skp, su2pov_tree.skp etc.) and I can't find them in the installation or in any zip file. Where do I find them? Or should they be in the 3.2 package but happen to be missing?
Another question: Is there a function for making a component a "piece of glass", i.e. give all its faces an interior definition with a IOR? Right now I'm doing it the hard way, pasting a "stolen" interior definition and references into the pov file, but there must be a simpler way...
Thanks for a great job!

Hi,
Release 3.2 and relase 2.4 are different, you guess. DON'T install 2.4 AFTER 3.2 !!! -
Hi again,
Yep, I do understand basic version numbers... But installing just the 3.2 version did NOT give me the buttons and component folders, so I tried installing the 2.4 anyway (even if it is an older version). So my question is: Is something missing in the 3.2 installer when I can't find the button toolbars and components? Or is the file su2pov_materials.exe supposed to install them? The problem is I get the following error message trying to run it:
Line -1:
Error: Array variable has incorrect number of subscripts or subscript dimension range exceeded.

Rickard

There are no toolbars and no icons in 3.2. Maybe in 3.3
su2pov_materials.exe is an executable that runs from within SU when you edit pov-ray material properties.

OK, that explains why...
Is it possible to get the 2.4 versions lights, 3D trees etc. somewhere? Or is a 3.3 version coming soon?

dear Didier . thanx for your nice jib on improving SU2POV.. and waiting to have v3.2beta ( material editor problem resolved )
. v3.2 was a great improve !!! 
yours kindly -
Dear Didier, Found this tread and after moving a copy of the su2pov folder into the components folder I am now able to use "lights" with the "esc" key.
I am still unable to "edit pov-ray" finishes. When ever I try to "apply" a change, a ASCII file titled "Program" is created in the root directory. The contents of this file include the selected changes. Apparently the file is not being saved in the proper location. (I discovered this file when I booted the computer and the boot process reported the file, requireing that it be renamed) When I again attempt to access the "edit pov-ray" menu, the menu would not open until I clear the file "Program" from the root directory. The title of the "edit pov-ray" menu is "Files/Google/Google". Is that right? I currently have su2pov.rb and the su2pov folder in the "plugins" folder. In addition, the su2pov folder is installed in the "components" folder.

Hi,
Thanks for the bug report. I also had a file on c:\ named "program" and never though it was my own script that did it ! Seems you've tracked the bug I'm on for a long time ! -
Didier, Glad to be of help, and Mahalo (thanks) for the script. I am looking forward to the patch.

I'm trying to build a demo of a Christmas Light display for a friend, but get some strange things with POV-Ray. This is a screen shot of the model and the POV Render Settings dialog.
The render is putting what appears to be a light at the origin as well as the light I placed. This is the render:
And the model:
Any idea what is going on?
-
Didn't find a problem with your file. Added SU color, spotlight, sky, ground and rendered.

For those who have problems with materials and lights in Su2Pov, the following:
-
As previously documented regarding placing the lights: First be sure that a copy of the Su2Pov folder is in the Su components folder. Use the <esc> key after selecting a Su2Pov light fixture to produce a cursor that will locate the light.
-
The "edit Pov-Ray Finish" menu is available if you start Su by selecting a project.skp with your mouse. If you start the program before opening a file, the menu may not appear. Once the program is started in this way, the menu is available, until you shut down. The dos screen flashes from time to time when the feature can not be accessed. Make sure that you edit component or group for access to a material.
Aside from always starting the program in this way is to make a shortcut of a untitled.skp, rename it SketchUp, and change the folder icon to the Su icon, place the shortcut where ever you start your program from. The drawback to this is that you can not start Su by dragging a file into the shortcut.
If anyone finds exception to this, let me know and I will edit this post.
