Its the approach thats lacking - hence this thread.Ĭan you provide a solution to the lofting challenge? The other way around is more challenging. Furthermore if you are very experienced in Direct Modelling, it is easy to switch to parametric. You should ask yourself what are planning to do. It seems like you are unclear about what you aim is. They also provide tools to create visual appealing surfaces, but you have no chance to create the same quality with those tools. are parametric modellers which allows you to do more technical parts, parts where the visual quality is secondary. Alias offers associative modelling same as Rhino, which gives you some sort parametric behaviour but without the typical treeview.įusion, Solidworks etc. Class A modelling is primarily done in Alias or Icem Surf (both direct modellers). Its a generalist software, and so its not perfect for specialised purposes. Rhino is a Direct Modelling software with a broad spectrum of features. is something you can’t und want to do parametric or generative. don’t learn in some days even weeks and B. Freeform quality surfacing is a process you A. Its a different concept for different purposes. Again “Direct” Modelling vs “Parametric” Modelling does not say the one can do more. Well I don’t know what you understand under “Surfacing”. So do baby steps in Rhino and see what should and what can be automated. It can be used as a tradeoff for surface pattern creation, but it is no replacement or improvement of surface modeling. It is the absolute wrong tool for surfacing. Grasshopper: To say it with HAL’s voice: Don‘t do this Dave. On a car this would look like a fender bender. The problem with twists is, that they change the reflection of your surface, making it very small at one end and very big on another and may also create local flatness or infliction, but even worse: If you match a surface to a twisted one, you also get a twisted one, but now you‘ve got a sine profile which is extremely bad. Of course you sometimes need to create twisted surfaces but this should be rare. You also want your edges to be of similar character which means they only diverge minimal. You want it proportional and as homogenous as possible. Twisted Surfaces: One criteria of a good model is to have very controlled curvature. If you want to judge a moving light, its a better to use some sort of directed point light, similar to a flashlight. Furthermore static highlights better reflect the lighting situation in a real world szenario. Its rather about seeing the reflections, its flow and its proportions. Zebras are misused as a continuity analysis, especially in Rhino. Static Highlights: It has already been answered.
