Computer rendering 3D renderings is particularly slow. Is it because the pulled model has not been remapped? Or something else? Ask for an answer! !

1. Modeling consumes a graphics card, but it also needs memory, but in these two cases, we need a graphics card more, because the memory of desktop or all-in-one machine and notebook is 2G or 4G, which is enough for us. If it is not a very large scene, there is no requirement for memory. Why is the graphics card important? Let me give you an example. A good graphics card can play games with high quality and special effects. Low graphics cards can only play games with low special effects and low image quality, so can the same games and models. In the same way, a good graphics card can model a big scene, and it will not become more and more stuck with the increase of the model. When we look at the graphics card, we should not only look at the model of the graphics card, but also look at several data of the graphics card. First of all, it depends on the number of stream processors and the type of video memory bandwidth, which is very helpful for our large-scale scene modeling. Of course, the bigger the data, the better; In fact, it is the connection rate between the graphics card and the memory. A good graphics card is useless if it has low memory, and vice versa. Therefore, a good graphics card naturally needs to be equipped with high memory, so that the graphics processing ability of the graphics card can be improved.

2.3D modeling: We need N card instead of A card. Everyone has questions, why not cards, but cards are suitable for painting. Yes, A card is suitable for drawing, but not for 3D, because Autodesk only supports N card, because 3D201220132014 released several years ago all support GPU rendering, that is, graphics card rendering, and supports N card. Although the graphics card rendering is not perfect at present, it will become the mainstream in the next few years. Graphics card rendering can greatly reduce rendering time, which is a great benefit for high-precision drawings, so we need N card. However, there are two kinds of N cards. The first choice is the Q series graphics card in the N card, which is a professional graphics card, followed by the game graphics card. Buy Q series graphics cards if you have the ability, and buy game graphics cards if you don't have the ability. The game map is right.

3. Many people don't know the choice of graphics cards for big scenes. If high-end graphics cards are a waste, then buying low-end graphics cards is also a waste. I don't know if I can buy a mid-range graphics card. Then I'll tell you, in fact, the requirements of 3D for graphics cards are not lower than those of 3D large-scale stand-alone games. What we need is a graphics card above the mid-range, which can run large scenes smoothly. There is no need to buy a high-end graphics card. We only need the GT650D5 on the market for the mid-range graphics card. No matter playing games or drawing, there is no pressure, and it can support large scenes around 250M, and 300M can also be used, but it may be a little small.

4. Rendering requires CPU, which has nothing to do with the graphics card. Now many people are confused about the choice of CPU. A good CPU can greatly reduce the time when rendering images, and there are also various CPUs on the market. Which CPU is suitable for VR rendering? It is best to render CPU with I7. After all, quad-core is good, I5 has no quad-core. Don't listen to the bluff of the merchants. First of all, we must see the model of CPU clearly. Let me give you an example. I7-3XXXU, I7 represents which generation of CPU3XXX of I7 represents, XXX represents the performance of CPU, and the larger the number, the better the performance; What kind of CPU does u stand for? There are several kinds of CPU on the market now, XM, MQ, HQ, K, U and XM are the best CPU, and six cores are the most suitable for shading, followed by MQ quad-core ordinary version, followed by HQ immovable CPU (non-removable), followed by M version, that is, ordinary version I7, only I5 and I3, and then K overclocking version, I7 does not.

5. Finally, the version before 20 10 does not support stand-alone display. Even if you buy a mid-range graphics card, it is useless to model a big scene with 2009. I suggest you use 3D after 20 12. They support discrete graphics cards.
