本文详细介绍了OpenGL中的glLoadMatrix函数，该函数用于用任意矩阵替换当前矩阵。当前矩阵可以是投影矩阵、模型视图矩阵或纹理矩阵。文章还解释了如何以列主序存储的16个连续值形式指定4x4矩阵。
glLoadMatrix
NAME
glLoadMatrix, glLoadMatrixf -- replace the current matrix with an arbitrary matrix
C SPECIFICATION
void glLoadMatrixd(GLdouble *m) void glLoadMatrixf(GLfloat *m)
PARAMETERS
m
Specifies a pointer to a 4x4 matrix stored in column-major order as sixteen consecutive values.
DESCRIPTION
glLoadMatrix replaces the current matrix with the one specified in m. The current matrix is the projection matrix, modelview matrix, or texture matrix, determined by the current matrix mode (see https://blog.youkuaiyun.com/jiangdf/article/details/8460012).
m points to a 4x4 matrix of single- or double-precision floating-point values stored in column-major order. That is, the matrix is stored as follows:
