Then using the push/pull tool extrude the polygon to the desired height and delete the faces at both ends of your pole, we don’t need them as they wont be seen. Before clicking, type the number of sides your polygon should have (six here) and press ↵ Enter. Let's start by making a pole for our umbrella.
Sketchup make faces how to#
Here is an example on how to make a low poly umbrella. But you can still reduce the number of faces in models.
Sketchup make faces software#
The main cause of such high number of faces in some models when using SketchUp and its simplified interface is the fact that this software was not produced with making low poly models for 3D games in mind. Heres how they all look in Flightgear from ground level.Īs you can see, you can achieve good result using only 15% of triangles to model umbrella (middle one), or even 9% by sacrificing some details (left one) and 29% in case of recliner.ĭecreasing the amount of faces (in SketchUp) The one on the left has 68 faces the one on the right 20! and in my opinion the one on the right looks better. Or, if you really want to make your scenery to take as low resources as possible you can build it using only 12 triangles. Taking into consideration those facts I think, we can still model this umbrella with quite nice level of detail using only 20 triangles (left image). Yes sure, most players will go to explore this beautiful scenery with helicopters, cars or UFO, but after a while most of them will perform “only” takeoffs and landings. That’s quite a lot for an object that is 2 meters high and the average pilot will fly over at between 80 - 140 knots at over 100ft. This tells us that there are 136 faces in the image. Have a look at the number underlined in red in the image above. Here you can see them without a texture or paint applied I’m sure you will agree that they look to all intents and purpose as they are designed to look you can see just from the picture the face count is bound to be different, but lets look a bit closer at them. Each of these is different in face count numbers, the one on the right having the most and the one to the far left the least. 2 Decreasing the amount of faces (in SketchUp)īelow you can see three beach umbrellas.On modern hardware you don't see much difference in frame rates in an aircraft with 150K polygons than one with 10K if they are otherwise very similar feature wise. Fact is that the scenery with clouds and other features will tend to have way MORE polygons than any reasonable aircraft model and modern graphics cards can handle millions of polygons at any given time so the aircraft model's complexity, if with in reason, is only a minor part of what the graphics card has to handle. My new 3D model has significantly more (perhaps 4 to 5 times as many) polygons than the one I am replacing and I am seeing, at most, a 1 FPS difference in frame rate that I can attribute to the new 3D model. For this demonstration we will use some simple models, used in the Princess Juliana International Airport scenery. It stands to reason that the less faces we use within a model the better it will integrate with FlightGear when you eventually place it in the Objects Database. The more memory that your computer uses to load a model, the less it has to keep the simulation at a good frame rate. Whenever you place your model in FlightGear the more faces a model has, the more bytes of memory that model will use up of your computer. Every time you connect 3 or more lines together you get a what is known as a face.
Lets start with telling you why the face count is important. This short article is designed to show you, the prospective modeller some very good tips when creating models for use within FlightGear or any other situation which is dependant on face count.
