It looks like glm 0.9.6 supports matrix decomposition http://glm.g-truc.net/0.9.6/api/a00204.html #include <glm/gtx/matrix_decompose.hpp> glm::mat4 transformation; // your transformation matrix. glm::vec3 scale; glm::quat rotation; glm::vec3 translation; glm::vec3 skew; glm::vec4 perspective; glm::decompose(transformation, scale, rotation, translation, skew, perspective);
Having the same ValueError, this is just the result of some testing and little research on my own, without the claim to be complete or professional about it. Please comment or answer whoever finds something wrong. Of course, your data should be in the right order of the index values, which you would assure with … Read more
Although the question is old, the other questions/answers don’t seem to provide a very clear step-by-step general answer on determining and decomposing relations to BCNF. 1. Determine BCNF: For relation R to be in BCNF, all the functional dependencies (FDs) that hold in R need to satisfy property that the determinants X are all superkeys … Read more
It’s called Partitions. [Also see Wikipedia: Partition (number theory).] The number of partitions p(n) grows exponentially, so anything you do to generate all partitions will necessarily have to take exponential time. That said, you can do better than what your code does. See this, or its updated version in Python Algorithms and Data Structures by … Read more
