Re: AOI - colored objects? Ok, I'll give here more details about the answer I posted yesterday at https://sourceforge.net/forum/message.php?msg_id=4562508 I you want to add colors to your OBJ models, you should open an OBJ file you generated in a text editor and study the tokens "g" and "usemtl" of the OBJ format described at http://download.java.net/media/java3d/javadoc...bjectfile/ObjectFile.html . The token "g" followed by a text, describes the name of a part of the object. For example in the railing.obj file you created, there is a line "g Cube_1". To specify the color of a part, add a new line under a line starting by "g", and type in that line "usemtl" followed by a space and the name of one of the colors described in OBJ format. Here is the list of supported colors : amber amber_trans aqua aqua_filter archwhite archwhite2 bflesh black blondhair blue_pure bluegrey bluetint blugrn blutan bluteal bone bone1 bone2 brass brnhair bronze brown brownlips brownskn brzskin chappie charcoal deepgreen default dkblue dkblue_pure dkbrown dkdkgrey dkgreen dkgrey dkorange dkpurple dkred dkteal emerald fgreen flaqua flblack flblonde flblue_pure flbrown fldkblue_pure fldkdkgrey fldkgreen fldkgreen2 fldkgrey fldkolivegreen fldkpurple fldkred flesh fleshtransparent flgrey fllime flltbrown flltgrey flltolivegreen flmintgreen flmustard florange flpinegreen flpurple flred fltan flwhite flwhite1 flyellow glass glassblutint glasstransparent gold green greenskn grey hair iris jetflame lavendar lcdgreen lighttan lighttan2 lighttan3 lighttannew lightyellow lime lips ltbrown ltgrey meh metal mintgrn muscle navy_blue offwhite.cool offwhite.warm olivegreen orange pale_green pale_pink pale_yellow peach periwinkle pink pinktan plasma purple red redbrick redbrown redorange redwood rubber ruby sand_stone sapphire shadow ship2 silver skin sky_blue smoked_glass tan taupe teeth violet white yellow yellow_green yellowbrt yelloworng For example in the railing.obj file you created, if you want the color of the part "Cube_1" be grey, you should add the line : usemtl grey As long as you don't add any other line starting by "usemtl" token, all the other following parts will be colored with the previously specified color. Thus, if you want to change the colors of the other parts, you should add other lines starting by "usemtl". Once, you have finished with these "usemtl" lines, save your file and try it in Sweet Home 3D Import furniture wizard. To help you choose a color, please download the image http://sweethome3d.sourceforge.net/Java3DCubeColorsWithTransparency.png : it shows all the colors listed above. You'll see that among these colors, some are transparent. You may use these colors for window panes. You can also name a part with a name starting by "sweethome3d_window_pane" to make that part transparent, as in the example http://sweethome3d.cvs.sourceforge.net/sweeth...content-type=text%2Fplain , that matches the "Double window" of Sweet Home 3D. Finally, don't hesitate to open the Sweet Home 3D OBJ files available at http://sweethome3d.cvs.sourceforge.net/sweeth...sweethome3d/io/resources/ , and the ones available at http://sweethome3d.sourceforge.net/importModels.html to view some real examples. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |
