Thats a good example how subdivision helps to get smooth surfaces with less effort.basic shape - looks smooth in sketchup - but the render shows the real surface30-09-_2020_10-13-3931142238 417 KBSame shape - subd 3 iterations added - looks much smoother in render.30-09-_2020_10-14-4030882140 752 KBAnd, you can switch on/off subd in sketchup for work with the mesh with lower amount of edges and faces.CheersTorsten (maybe a subd addict)
Subdivide And Smooth Plugin Sketchup 35
Once I had a series of lines ready to loft, I started the Curviloft plugin. The process is really straight forward. (4) I choose the first spline curve, (5) then I choose the second spline curve, (6) and then hit the check mark twice to complete the process. The plugin creates a smooth surface between the two spline curves, allowing you to choose how many times to subdivide the surface among other options. The best part is that the plugin is really stable and can be used inside of groups.
Displacement: Select the image that will be used as a displacement map.Subdivision: Defines the times the actual mesh will be subdivided. Large values will create a more detail surface.Height (cm): Defines the height of the displaced surface in cm. The maximum value will be used for the white areas of the displacement map.Center: Areas with black mean no displacement and white 100% displacement (corresponding to the height you have ginen). This is true when center is set to 0, but if you change to 0,5 then 50% gray color of the displacement map will represent no displacement and when set to 1 then 100% white will represent no displacement (in other words it will displace the opposite way). This inverted displacement is sometimes useful, like for the ground plane displacement where you want to avoid intersecting with objects that are on the ground, as for example a car wheel that is on a displaced ground, so in this case you would set the center to 1.Normal Smoothing: This option should be enabled for surfaces with smooth edges. For models with sharp edges (box, plane, etc) it should be disabled.Tight Bounds: Helps to render faster but initialization will last longer. This is more preferred to have it enabled.
In this model, the microscopic structure of the surface is assumed to be perfectlysmooth, resulting in a degenerate BSDF described by a Dirac delta distribution.This means that for any given incoming ray of light, the model always scatters intoa discrete set of directions, as opposed to a continuum. For a similar model thatinstead describes a rough surface microstructure, take a look at theroughdielectric plugin.
This plugin is essentially the roughened equivalent of the (smooth) pluginconductor. For very low values of \(\alpha\), the two willbe identical, though scenes using this plugin will take longer to renderdue to the additional computational burden of tracking surface roughness. 2ff7e9595c
