其次,边界轮廓环的三角网格化:层间三角面片填充和端面三角划分。
Secondly, the triangle meshing of contour loops that includes triangle plane filling between layers and section triangle plotting was accomplished.
观察上面这个形状相同的网格体:156个三角形面片(右)和726个三角形面片(左)。 726个面片可能听起来不会是很多的多边形,但如果这是在关卡中变成40倍,你会真正开始看到优化后节省下来的面片。
Observe the same shape mesh : 156 triangles (right) vs 726 (left). 726 may not sound like a great deal of polygons, but if this is used 40 times in a level, you will really start to see the savings.
运用计算机绘制虚拟模型的方式有网格、面片以及NURBS等多种;
There are many methods to protract virtual model by computer, for example grid, patch and NURBS and so on;
提出了一种仅根据三角网格模型的三角面片集合计算模型体积的方法。
In this paper, a new volume calculation method for arbitrary triangular mesh is presented based on the triangles set of the mesh only.
并对其生成的表面几何模型所包含三角面片数量巨大的问题,提出一种快速有效的三角形边收缩算法进行网格简化,提高了表面模型的绘制速度。
Because 3D surface model contains huge number of triangles, a mesh simplification algorithm based on triangle edges shrinkages is presented in this paper to speed up the rendering in real time.
细分曲面存在的一个问题是随着细分次数的增多,网格的面片数迅速增长,巨大的数据量使得细分后的模难以进行其它处理。
One problem in subdivision surfaces is the number of facets grows exponentially with the level of subdivision. Subdivision schemes are cost intensive at higher levels of subdivision.
