− | == Sharpen ==
| |
| | | |
− | The sharpening tool carries out two actions: it smooths the planar parts of the surface and, at the same time, it sharpens the edges, using two parameters:
| + | == 高级平滑 == |
| | | |
− | # T [°] : this angle identifies what an edge is. All the parts of the surface that have an angle smaller than T° will be sharpened. When this value is at 0, all the surface will be smoothed
| + | '''高级平滑'''工具使得网格整个表面变得平滑,补偿其不规则性。 |
− | # Normal Iterations : how many times the software will pass over the surface to carry out the sharpening. The higher the value, the more the mesh will be smoothed and sharpened
| |
| | | |
− | '''The software applies this tool automatically, using specific parameters. The use of this tool with the wrong parameters may modify the shape and the dimension of the objects'''.
| + | [[File:Adv-smoothing.jpg]] |
| | | |
− | == Smooth ==
| + | 此工具应用一系列参数: |
| + | ; 迭代:工具被应用的次数。 |
| + | ; 强度:工具可以改变多少对象表面。值越高,网格越平滑和锐化越多。 |
| + | ; 灵敏度:表面的几个部分将被识别为“细节”(边缘)。细节部分将被削尖,但不光滑。 |
| + | ; 保护::多少'细节'部件不会磨尖。 价值越高,细节越细越小。 |
| + | ; 最大偏差:工具可以修改多少网格形状。这是每个点从原始网格到最终网格的最大距离。 |
| + | ; 翻转边缘:如果启用此选项,工具将重新排列网格结构,以更好地表现边缘。 |
| | | |
− | This tool is similar to the Mesh Sharpening but it applies a smoothing to the whole surface, without preserving the edges.
| + | '''软件使用特定的参数自动应用这个工具。在此工具上使用错误的参数可能会修改物体的形状和尺寸'''。 |
| | | |
− | '''The software applies this tool automatically, using specific parameters. The use of this tool with wrong parameters may modify the shape and the dimension of the objects'''.
| |
| | | |
− | == Adv Smoothing == | + | ==抽取== |
| | | |
− | The '''Advanced Smoothing''' tool is an improved version of the '''Smooth''' tool because it grants more control, more parameters and better results.
| + | 此工具可减少在一个网格的三角形的数量,以节省更多的空间,试图尽可能地多保留细节。 |
| | | |
− | {{Screenshot|Adv-smoothing.jpg}}
| + | [[File:Dental_2_5_decimate.jpg]] |
| | | |
− | The parameters are:
| + | 顶部说明了所选网格三角形的当前数目。 |
− | ; Iteration : Number of times the tool will be applied.
| |
− | ; Strenght : How much the tool can change the object surface. The higher the value the more the mesh is smoothed and sharpened.
| |
− | ; Sensitivity : How many parts of the surface will be identified as 'Details' (margins, edges). The details parts will be sharpened, but not smoothed.
| |
− | ; Protection: : How many 'Detail' parts will not be sharpened. The higher the value the less the small details are sharpened.
| |
− | ; Max Deviation : How much the tool can modify the shape of the mesh. This is the maximum distance every point of the final mesh can have from the original mesh.
| |
− | ; Flip Edges : If this option is enabled the tool will rearrange the mesh structure to better represent edges.
| |
| | | |
− | == Decimate ==
| + | 可以插入保留的三角形百分比(例如50%,網格的大小減半) |
| | | |
− | This tool reduces the number of triangles in a mesh, to save more space, trying to preserve as much detail as possible.
| + | 另外,也可以建立一个容差值。如果容差被启用,当修改大于容差值参数的网格时,该软件将停止抽取。 |

| | | |
− | This is an interactive tool that allows to fill the holes in the currently selected mesh.
| + | 在填补一个模式中,该软件将高亮显示鼠标指针附近的孔。鼠标左键点击高亮显示的孔,该孔将被填充。 |
| | | |
− | {{Screenshot|Dental 2 5 fillHoles.jpg}}
| + | ===填充所有=== |
| | | |
− | This tool can work in 2 different ways

− | === Fill One === | + | ===填充曲率=== |
| | | |
− | In the fill one mode, the software will highlight the hole near the mouse cursor. By clicking with the left mouse button on the highlighted hole it will be filed.

| | | |
− | === Fill All === | + | == 关闭义齿 == |
| | | |
− | In the fill all mode, the software will try to close all the holes. With the ''Filter By Size'' function, it is possible to select all the holes below one size and fill them. The selected holes will be highlighted in real time by the sofware.

− | === Curvature Filling ===
| + | 利用关闭义齿工具,网格将在少量的时间中被一个理想的平面关闭。 |
| | | |
− | There is an additional option: curvature filling. If this option is enabled, the software will try to close the hole following the curvature of the rest of the surface. If it's disabled, the software will ignore the rest of the surface and close the hole with a straight plane.

编辑网格
由扫描器获取的数据生成一个网格时,所述网格可能对于所设计的用途而言并不完美。
所生成的网格可能具有缺陷、噪点或需要被填补的孔。
OpticalRevEng Dental已对每个组件应用一个特定的网格生成策略。但是,有可能需要将网格导出到其他软件前进一步编辑它们。
在这个网页中介绍了网格编辑工具,也可以查看网格菜单或网格工具栏进行了解。
移除尖角
尖角定义为不属于扫描器采集的3D物体、在其表面上的一小部分。
通常,这些尖角由软件在生成网格中自动校正,但如果该网格从另一系统导入,则可能存在一些尖角。
此工具会自动删除所有的尖角同时修复网格。
高级平滑
高级平滑工具使得网格整个表面变得平滑,补偿其不规则性。
此工具应用一系列参数:
- 迭代:工具被应用的次数。
- 强度:工具可以改变多少对象表面。值越高,网格越平滑和锐化越多。
- 灵敏度:表面的几个部分将被识别为“细节”(边缘)。细节部分将被削尖,但不光滑。
- 保护::多少'细节'部件不会磨尖。 价值越高,细节越细越小。
- 最大偏差:工具可以修改多少网格形状。这是每个点从原始网格到最终网格的最大距离。
- 翻转边缘:如果启用此选项,工具将重新排列网格结构,以更好地表现边缘。
软件使用特定的参数自动应用这个工具。在此工具上使用错误的参数可能会修改物体的形状和尺寸。
抽取
此工具可减少在一个网格的三角形的数量,以节省更多的空间,试图尽可能地多保留细节。
顶部说明了所选网格三角形的当前数目。
可以插入保留的三角形百分比(例如50%,網格的大小減半)
另外,也可以建立一个容差值。如果容差被启用,当修改大于容差值参数的网格时,该软件将停止抽取。
只需单击“应用”以查看结果。

- 使用选择工具选择要除去所有“特征”的区域
- 应用删除网格特征
连接
这个工具只能用于自由模式。它提取所有选择的网格,并创建一个单一网格,将所有选定的网格合并在一起。
翻转法线
每个网格具有内侧和外侧。软件给他们两种不同的颜色。此工具翻转所选择网格的内侧和外侧。
填充所有孔
这是一个交互式的工具,可以用于填补当前所选网格的孔洞。
