描述

hom_mat2d_identityhom_mat2d_identityHomMat2dIdentityHomMat2dIdentityHomMat2dIdentityhom_mat2d_identity generates the homogeneous transformation matrix HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentityhom_mat_2didentity describing the identical 2D transformation:

注意

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is not stored because it is identical for all homogeneous matrices that describe an affine transformation. Thus, HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentityhom_mat_2didentity is stored as the tuple [1,0,0,0,1,0].

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
