Edge loop is a very important concept in modeling, which determines the final shape of the model.
According to the principle mentioned above, the closer the line is, the harder the structure.
The diamond structure is a very important and practical technique in modeling.
The shield model and the top six lines finally converge on the bottom corner. Because the upper part of the shield is a relatively wide structure, we need more faces to form its structure. But the bottom corner is a very small structure, and we don't need so many faces. This wiring will make the bottom surface look very crowded, wasting a lot of surfaces, and it is also very inconvenient for subsequent modifications. So, how should we optimize the lines here? This requires the so-called diamond structure.
After the modification, the upper part of the model still has six faces, but at the bottom corners, there is only one face. Such lines are evenly distributed on the model. By using the diamond structure many times, the number of faces can be gradually reduced, and the wiring of the model can be more optimized.
At the same time, the diamond structure can not only play the role of lowering the surface, but also can play the role of raising the surface. If we look at the wiring in reverse, it actually starts from the bottom side and gradually increases the number of sides to the top six sides. We must flexibly use the positive and negative effects of the diamond structure according to the different situations of the model.
Sometimes the model may need to have some very regular structures. For example, this model has a semicircular structure on top and bottom. The best choice is to use some basic shapes to make it. The cylindrical shape is probably used the most.
First create a cylinder and adjust the size of the lower cylinder. The parameters here are set as integers as much as possible to facilitate the matching of the size of the lower cylinder. At the same time, it needs to reduce the number of segments of the cylinder, so there is no need for so many segments, leaving 12 segments.
Delete the unused half of the surface and extrude the structure below; create a new cylinder, reuse the shape again, adjust the parameters of the bottom cylinder, and pay attention to matching the size of the structure above.
Then we can select all the lines at the break and use the stitching tool to connect the two structures. The last is some follow-up work, cleaning up the number of faces and so on.
