这部分代码如下: // 开始递归迭代while(true){if(Consts.InnerGraphByAngle(Vector2.zero,SimplexList.ToArray()))returntrue;// 通过距离原点最近的单纯形边,找到新的单纯形顶点Vector2edge=GetCloestEdgeToOrigin(SimplexList,outvarindex1,outvarindex2);Vector2newNode=GetSimplexNode(GetPerpendicularLineToOrigi...

将这些点全部包围起来,如果这个新生成的图形包含原点,则意味着两个图形发生了重叠,从而判断两个图形发生了碰撞。我们把计算后的点称为闵可夫斯基差(Minkowski Difference),将生成的三角形/线形称为单纯形(Simplex)。 将两个图形包围的点相减,不仅是手算费劲,使用计算机算也相当耗时。或许,我们可以根据多边形的特点,只...
on two dimensional (2D) simplex. We provide some examples of d.s.q.o. which have infinitely many fixed points. We prove that the trajectory of extreme d.s.q.o., starting at some interior point of the simplex is convergent. Finally, we classify the dynamics of all extreme points of d...
分别对应线性插值和光滑插值,又称缓和曲线(Ease Curve)。对于顶点的梯度向量,有的约束其长度为1,此处采用单位圆约束,即一个顶点的梯度向量应当位于所在网格的单位圆内。部分柏林噪声的实现为增强随机性还需指标随机化取模查哈希表,还有改进版Simplex噪声和分形柏林噪声等,此处不考虑。
我直接使用了Unity wiki上的代码,它使用4D的Simplex噪声来产生无缝的2D噪声纹理,没采用Perlin噪声的原因是Simplex在高纬度上的计算复杂度要小的多,具体可参见【图形学】谈谈噪声。 这样,我们就得到了4张噪声纹理以及它们按权重相加得到的分形噪声: 在运行时刻,我们只需要按不同的速度来移动这些噪声,这些速度只要不会...

Simplex noise looks better, but different, and is thus visually incompatible with classic Perlin noise. The difference in feature size and range of values can easily be compensated for by a few simple scaling multiplications, but the different visual character might change the visual result of shad...
