How is the 3d wall object (baserail specifically) constructed? I am exploring possible enhancements to the wall object, specifically the addition of a profile path to the baseboard with the intention of duplicating its functionality as a cornice. Straight walls are no problem as we are just bulding boxes and the functionality of a cornice isn't really required as I can just add them as furniture and stretch to fit. Curved walls are where the fun is. As baseboards start out life as a box I can see two ways that they would be constructed; 1) Calculate the curve and extrude vertically, or 2) Take the vertical profile and extrude along the curve. 1 would not adapt easily to a variable profile but 2 would be doable. I'm trying to make sense of the wall3D class and from having a look it seems that the three visible points of a baseboard are propagated along the curve. This implies that it might be possible to increase the number of visible points to produce a profile that is not square. Am I reading it right? Jay |

Re: How is the 3d wall object (baserail specifically) constructed? If you look at Wall3D class, you'll see that the method createWallGeometries is used to create the main parts of a wall and also to create baseboards as if they were some small walls. Maybe you could inspire yourself of the same system for a cornice, except that you will have to manage a profile in createVerticalPartGeometry method instead of a simple vertical plan which makes it more difficult. Round walls are actually a serial of small vertical parts and you should create a getWallCornicePoints that will return the global shape of the cornice along the wall like getWallBaseboardPoints does. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |
