首先,让我们来看看cross函数的基本语法: real cross(vector A, vector B); 这个函数需要两个向量作为输入。向量A和向量B都必须是三维的。输出将是一个实数标量。下面是cross函数的更详细描述: 1.这个函数将向量A和向量B构建为一个三维向量,其中向量A的xyz分量分别是A.x、A.y和A.z,并且向量B的xyz分量分别是...

cross=abs(dx1\*dy2-dx2\*dy1)heuristic+=cross\*0.001 这段代码计算初始-目标向量(start to goal vector)和当前-目标向量(current point to goal vector)的向量叉积(vector cross-product)。When these vectors don't line up, the cross product will be larger.结果是,这段代码选择的路径稍微倾向于从初始...

The Roads layer is not a raster layer; it's a vector layer that represents features as lines. (Other types of vector layers can contain points or polygons.) Each line represents a road, ranging from small roads to major highways, although you will not distinguish between these different typ...
