![]() Again, your personal experience of the software will still be the final arbiter. *Before we dive in, just a quick note: the pros and cons detailed here are best taken with a grain of salt, of course. Now that we’re all acquainted with the 3D process, let the throwdown begin! This way, it’s faster and you can actually meet your deadlines. To cut this time down, many 3D rendering software lets your GPUs do the job instead of the CPU. It’s very taxing and therefore takes a lot of time. These calculations are handled primarily by your computer’s CPU. Your computer has to solve gajillions of mathematical calculations in order to tell each 2D pixel on your screen what part and with what property (color, light, shading, etc.) of the original 3D image to display. Technically speaking, this step is the actual rendering step. It’s now time to convert your 3D image into a format that can be displayed properly and consistently on the 2D screens of people’s laptops, mobiles, and tablets. Now, let’s say you are already happy with how your Iron Man looks. Different rendering software have different ways of calculating light which affect how your finished product looks. One of the most important aspects here is lighting. Now that you have a UV-mapped model, you can now situate it in an environment, paint it, give it metallic properties, and apply all sorts of effects. The shader is the 3D world’s term for describing what kind of surface your 3D model has for example: is it wooden? Metallic? Glass?) This “tagging” produces a map of your 3D model which is then plugged into a Material or Shader. Usually, you’ll need a separate texturing program for this. This is the part where the software sort of “tags” every part of the surface of our 3D-modelled Iron Man. To turn this sculpted clay into a photo-realistic Iron Man, you need to take a few more steps: Your 3D model of Iron Man may have all the plates and grooves and layers of his armor but it still just looks like gray clay. You start with a mound of clay (usually you start with a basic shape, like a sphere) which you then sculpt, trim, pull, twist, and manipulate in all sorts of ways inside the 3D modeling program to come up with, say, Iron Man. You see, 3D modeling is like working with clay. Now a lot goes into that one word, awesome. And why would you want that? Because in most cases, rendering using your GPU or (GPUs) is much faster.īut before we go any further, let’s first refresh our minds on what 3D rendering is, so that all these can make more sense.ģD rendering is the last step in the process of creating 3D graphics, where we take completed (but bland and raw) 3D models and make them look awesome. GPU 3D rendering simply means that the rendering process is performed by your computer’s graphics card as opposed to the CPU. This deserves a bit more explanation and some definition of terms. Under versatility falls the software’s ability to make use of your graphics processing unit (GPU for short, also commonly called graphics card) when doing your renders. For many 3D artists, the main factors are speed, look, and versatility. The whole point of that car metaphor was simply to show that there are many things to consider when deciding which 3D rendering software is best for you. ![]() ![]() An SUV gets you to your destination as well as a pickup but a pickup lets you bring oversize loads. A muscle car gets you to your destination as well as a subcompact but a subcompact is easier to park and guzzles less gas. All cars get you from point A to point B (or at least they should), but how the vehicle does so varies greatly, and what’s “best” is determined by what you’re looking for. In short, different strokes for different folks. There simply isn’t a one-software-fits-all solution, since there are a lot of different factors to consider, and they differ from one 3D artist to the next. The idea of “best” depends on your needs, your project, your process. Of course, the ultimate judge of what’s best will be you. Or isn’t there? That’s what we hope to help you find out. It may have got you thinking, “there can’t possibly be one objectively ‘best’ rendering engine out there, is there?” Okay, a confession: that title may have struck you as a little bit of a clickbait.
