叉积(英语:Cross product)是一种在向量空间中向量的二元运算。与点积不同,它的运算结果是一个向量而不是一个标量。两个向量的叉积写作 ,也称作外积(英语:Outer product)或向量积(英语:Vector product)。叉积与原来的两个向量都垂直。 定义 两个向量 和 的叉积写作 (有时也被写成,避免和字母 x 混淆)。叉...

还有例如列向量:Vector3f,其本质也是Matrix类: typedefMatrix< float, 3, 1 >Vector3f; 行向量RowVector: typedefMatrixRowVector2i; 静态-动态-矩阵 静态矩阵:矩阵是静态的,即编译时候就知道运行结果,例如Matrix3d:表示元素类型为double大小为3*3的矩阵变量,其大小在编译时就知道。
为什么会抛出编译错误:没有匹配的函数来调用“cross(glm::vec4&,glm::vec4&)”glm::vec4 b; glm::vec4 c = glm::cross 浏览0提问于2012-05-26得票数 4 回答已采纳 2回答 仅用于特定类型的泛型类的方法 、 其中N是向量的大小(或维度)。向量有一个叉积方法,它计算叉积: cross(vector: Vector<N>...
