  1. I did not know that, thanks for the clarification. I will read more in this post to see if solves the issue I'm describing.
  2. Hello I have created a topic: Stud.io, exporting POV-ray files, some is covered here. The new topic focus on editing .pov files exported from Stud.io and then rendered from a mac OS terminal. Right now I'm learning to edit .pov files. I'm trying to adapt the lines of code from CRPOwen' guide to the .pov file exported from Stud.io. But I had some trouble, because the .pov file, already has a macro for lights: WriteLight(0, 0, 1, 0, 200, 5) . If I remove that macro (see line below), somehow the rendering fails. I'm trying to understand more of the POV-ray language to find whats happening. Any help will be greatly appreciated. Solution Update: .pov files exported from Stud.io give me some trouble, so instead, from stud.io I export a .ldr file, which then I open in LDView, and from there I exported the .pov file. This also allow me to select the perspective of the model, and automatically translated to the .pov file (Which I could not do it in Stud.io). At first time the .pov file exported from LDView has mismatch colors, that was fixed updating the file /Applications/LDView.app/Contents/Resources/LGEO.xml. NOTE: I will eliminate the topic I created, or maybe change to focusing on mac OS related issues of POV-Ray Rendering.
  3. Yes, very useful that guide, thanks. I'm trying to adapt the lines of code mentioned there (like the one you mention, 7.6 Radiosity) to the .pov file exported from Stud.io. But I had some trouble, because the .pov file, already has a macro for lights: WriteLight(0, 0, 1, 0, 200, 5) . If I remove that macro (see line below), somehow the rendering fails. I'm trying to understand more of the POV-ray language to find whats happening. I will post this question in the guide you provide me. #macro WriteLight(Lat, Lon, LightPower, Shadowless, AreaLightWidth, AreaLightColumns) #local latRad = radians(Lat); #local lonRad = radians(-Lon)-CameraTheta; #local sinLat = sin(latRad); #local cosLat = cos(latRad); #local sinLon = sin(lonRad); #local cosLon = cos(lonRad); #local lightVectorSize = 4.0*LDXRadius; light_source { <lightVectorSize*((-sinLon)*cosLat),lightVectorSize*(-sinLat),lightVectorSize*(-cosLon)*cosLat> + LDXCenter color rgb <1,1,1>*LightPower #if (Shadowless = 0) #if (AreaLightWidth > 0) area_light AreaLightWidth, AreaLightWidth, AreaLightColumns, AreaLightColumns adaptive 1 jitter circular orient #end #else shadowless #end } #end // Lights // camera fai = 0 // camera theta = 0 WriteLight(0, 0, 1, 0, 200, 5)
  4. Hello all, I'm a beginner in rendering LEGO models in a mac OS system. I discovered that Stud.io makes its renderings using POV-ray (a software for rendering) and that you can export .pov files for render externally in the POV-ray software itself. The POV-ray 3.7 has not graphical user interface (GUI) for mac OS X, and can only be executed in the command line. The render is controlled in a text file with the .pov extension. I installed POV-ray 3.7 with the sotware mac ports: [ The command is: sudo port install povray @3.7.0.0_2 ] Then I modified the file /opt/local/etc/povray/3.7/povray.ini adding the path to the LGEO libraries, which were already installed by Stud.io. Library_Path="/Applications/Stud.io/povray/LGEO" Library_Path="/Applications/Stud.io/povray/LGEO/lg" Library_Path="/Applications/Stud.io/povray/LGEO/ar" Also modifying the Width and Height parameters. Then in the mac terminal I ran: povray Nova_AlexandriaFrontal_10.pov The result is similar to what I have obtained in Stud.io renderings. Now I want to improve the renderings learning to use POV-ray. First step learning about lights. Which I will update in this post. Any advice will be greatly appreciated, which will be included here. Solution Update: .pov files exported from Stud.io give me some trouble, so instead, from stud.io I export a .ldr file, which then I open in LDView, and from there I exported the .pov file. This also allow me to select the perspective of the model, and automatically translated to the .pov file (Which I could not do it in Stud.io). At first time the .pov file exported from LDView has mismatch colors, that was fixed updating the file /Applications/LDView.app/Contents/Resources/LGEO.xml. NOTE: I will eliminate this topic to create a new one with the focus on mac OS related issues of POV-Ray Rendering.
