Top 9 Free And Best 3D Modelling Websites in 2023

Today, Fox Renderfarm, the industry's leading cloud rendering service provider and render farm, will bring you a 3D tutorial that explains how to make a handheld fan. Let's get started right now.First import the image, use the straight line tool to draw the length of the handle, then use the rotational molding tool to create the handle and add a cover.Generate a rectangle using the center point, adjust it to the appropriate size, and then generate a circular runway. At this point, use the fitting tool to get the appropriate shape.Select the circular runway that was just generated, hold down Shift to extrude the faces on both sides and add a cover, then use the shell tool to shell both sides.Copy the inner edge line of the shell, extrude the face and add the cover, pull off the inner face to keep only the outer side, and then chamfer to generate the outer layer of the shell that needs to be hollowed out.Use curves to draw the edge shape of the connecting axis, then use rotational molding to generate the surface, and then add the cover to generate the solid.Connect the rectangle diagonal, use the diagonal to generate a round tube, and adjust the angle and thickness of the tube so that the angle and thickness of the tube match the reference picture.Draw a diagonal line again and use the Line Array tool to array along this line, where the number of arrays is 18.Use the object intersection line function to select the round tube and the shell to be hollowed out, determine whether the position matches by the object intersection line, adjust the position and then cut to get the hollowed out object.Use the Rectangle tool to generate a runway circle, adjust it to the right size, then cut and combine it with the hollow object and offset it inward to get the solid. The same can be done for the outer runway circle, here you need to make a copy of the hollow object for backup.Use the mirror tool to mirror the hollowed-out model made in the previous step to the back, then use the method in the fourth step to get an unhollowed-out shell, generate a rounded rectangle and cut it according to the second reference picture, then use the combination tool to combine, and finally offset the surface to get the solid.Use a rectangle to frame the size of the button, then use a straight line to connect the midpoint of the rectangle, next use the center point tool to generate a circle, and squeeze the circle to the right size and adjust the height of the button.Split the button and the handle for spare, and then chamfer the top of the handle for the next step.For the base, again using the rotational molding tool. First draw the edge shape using curves, then rotate the shape and cap it to create a solid.Now perform the Boolean split between the handle and the base, then detach the surface. Next, copy the edge line, move the inner circle downwards, use the double rail sweep to generate the surface and combine it to obtain the base shape.Use the center point circle and rectangle tools to generate the button and indicator light shapes on the handle, extrude the solid and then perform a boolean split with the handle to get the handle shape and the indicator light.Use the Rectangle to create the runway circle and rotate it 45° to get the "x" below, then use the Trim tool to trim off the excess lines and combine them. After extruding the surface, use the Boolean split tool to split it to get the "x" icon.Now create the circular texture on the button. First abstract the structure line to get a button-sized circle, then generate a circle solid at the circle node, and use the Array Along Curve tool to make an array. Arrange the five columns in sequence according to the image and mirror them to get the desired texture. Finally, we use Boolean split to get the button shape.Chamfer the intersection of the button and the handle, and chamfer the intersection of the handle and the base.Use the curve to draw the fan shape, then use the XN tool to generate the surface, and array along the center point. The number of arrays here is 5. Adjust the fan blade position and extrude the fan blade solid.Check the model and chamfer it to complete the model.The next step is to render the product. First, divide the product into four layers, one for the orange object, one for the flesh-colored object, one for the metal connection, and one for the self-illumination. Then start rendering.First adjust the model position by aligning the model to the ground in the Advanced Options.Set the model materials to the model in turn. Note that you need to turn down the metallic shine of the metal joints in order to get a frosted look.Adjust the self-luminous material on the handle to the right intensity in accordance with the light, and choose white as the color.Set the setting options in the image to Press Exposure, High Contrast, and Photography.Change the background color in the environment settings. Use the straw tool to absorb the image color, turn down the brightness of one light in the HDR editor, hit the light on the hollow surface, adjust the shape of the light to rectangle, and then hit a main light on the left side of the product to make a shadow appear on the right side.Adjust the object position in the camera, lock the camera, and finish the rendering.Source: YBW

As the last procedure to complete the CG work, 3D rendering is time-consuming and patience-consuming, but very important. Many newcomers to the 3D industry may not understand why 3D scenes take so long to render, and what factors are related to the speed of 3D rendering. In this article, Fox Renderfarm, the leading cloud rendering service provider and render farm in the CG industry, will discuss with you how to improve the speed of 3D rendering.3D rendering is slow because it involves various aspects working together, such as your software, renderer, graphics card, RAM, etc., so it takes a lot of calculations to form the final render. So the rendering speed is actually mainly related to your computer configuration, the software used and the scene or model, which are several factors.How to Improve 3D Rendering Speed?1. Upgrade Your MachinesRendering relies heavily on the CPU performance and RAM of your computer. Low computer specs will result in long rendering times. If you want to render faster, you need a more powerful processor, as well as upgrading your RAM.2. Upgrade Your SoftwareVarious 3D software and their renderers basically receive an update at regular intervals, and each update results in a faster and better rendering experience. So if you have the idea to speed up rendering, it is better to update all your software to the latest version. Of course, it is worth noting that in addition to the optimization of rendering features, other functions or stability of the new version should also be taken into consideration.3. Optimize Your Scenes and ModelsRemove or hide models, objects, and faces that are not visible to the camera.Adjust mapping, reduce the use of shadow mapping, remove displacement mapping, and use geometric and bump mapping whenever possible.Reduce lighting and optimize lighting parameters.4. Use Cloud Rendering to Speed Up RenderingThe magic of cloud rendering lies in the ability to use multiple machines at the same time to help you render your scene, and it in the end compresses hours of rendering time into minutes.If you have to maintain high quality rendering and it causes long rendering time, it is also recommended to use cloud rendering farms to help you out with batch rendering and extremely fast rendering in the cloud.

Pre-Rendering vs Real-time Rendering"Avatar" directed by James Cameron spent four years and nearly 500 million US dollars to open a new world of science fiction for everyone. The CGI characters, Names, in the film look exactly the same as the people in the real world. And the realistic sci-fi scenes are shocking. However, these wonderful images are inseparable from the CG artists and pre-rendering technology.In order to solve the rendering tasks of "Avatar", the Weta Digital supercomputer processes up to 1.4 million tasks per day to render movies, running 24 hours a day with 40,000 CPUs, 104TB memory and 10G network bandwidth. It took 1 month in total. Each frame of "Avatar" needs to be rendered for several hours, 24 frames per second. Hence, the powerful rendering cluster capability is really important to the CG studio.What is pre-rendering?Pre-rendering is used to create realistic images and movies, where each frame can take hours or days to complete, or for debugging of complex graphics code by programmers. Pre-rendering starts with modelling, using points, lines, surfaces, textures, materials, light and shadow, visual effects and other elements to build realistic objects and scenes. Then, computing resources are used to calculate the visual image of the model under the action of factors, such as viewpoint, light, and motion trajectory according to the predefined scene settings. The process is called pre-rendering. After the rendering is completed, the frames are played continuously to achieve the final effect.It is mainly used in the fields of architecture archive, film and television, animation, commercials, etc., with the focus on art and visual effects. In order to obtain ideal visual effects, modelers need to sculpt various model details during the production process; animators need to give the characters a clever charm; lighting artists need to create various artistic atmospheres; visual effects artists need to make visual effects realistic.Commonly used pre-rendering software including 3ds Max, Maya, Blender, Cinema 4D, etc., which are characterized by the need to arrange the scene in advance, set the relevant rendering parameters, such as shadow, particle, anti-aliasing, etc.), and then use a PC or render farm to render with unsupervised calculation.BTW, you can use a local machine or a cloud render farm for rendering. Fox Renderfarm can provide rendering technical support for the software mentioned above.Each frame in the pre-rendered scene is present. Once the rendering is started, each frame takes several seconds, minutes or even hours to render. A large amount of memory, CPU/GPU, and storage resources are consumed during the rendering process, which is a computing resource-intensive application. Especially in film and television projects, there are usually scheduled requirements so that rendering tasks need to be completed within a specified time. Currently, tasks are basically submitted to cloud rendering farms for rendering. Cloud rendering farms, such as Fox Renderfarm, are professional service companies that can provide massively parallel computing clusters.After pre-rendering, the task is basically the finished work that has been rendered. If you want to calculate and see the scene in real time on an operable online service or online game, we have to talk about real-time rendering.What is real-time rendering?In August 2020, a live demonstration of the action role-playing game "Black Myth: Wukong" produced by Game Science Corporation from China became popular in Chinese social networks. The top-notch pictures, rich details, immersive combat experience, and sufficient plot interpretation in the demonstration restore an oriental magical world. Every beautiful scene in the game is rendered in real time.Real-time rendering is used to interactively render a scene, like in 3D computer games, and generally each frame must be rendered in a few milliseconds. It means that the computer outputs and displays the screen while calculating the screen. Typical representatives are Unreal and Unity. Games like Game Science are built using Unreal Engine 4. The characteristic of real-time rendering is that it can be controlled in real time and is very convenient for interaction. However, the disadvantage is that it is limited by the load capacity of the system. And if necessary, it will sacrifice the final effect, including model, light, shadow and texture, to meet the requirements of the real-time system. Real-time rendering can currently be applied to 3D games, 3D simulations, and 3D product configurators and others.Real-time rendering focuses on interactivity and real-time. Generally, scenes need to be optimized to increase the speed of screen calculation and reduce latency. For the user, every operation, such as a finger touch or click the screen, will make the screen to be recalculated. And the feedback needs to be obtained in real time. Thus, real-time rendering is very important. In simulation applications, the data shows that only if the latency is controlled within 100ms, people will not obviously perceive the inconsistency of video and audio.In recent years, with the improvement of GPU performance, the speed of real-time calculation is getting faster; and the accuracy of the calculation images is getting higher. Especially with the application of Ray-tracing and other technologies, the effect of real-time rendering becomes more realistic. These top technologies are also obvious trends in future production.
