| | | | | Normally when writing OpenGL code, it can get very cumbersome/error-prone when defining how to pass vertex data to the GPU. As a given example, heres a toy vertex structure we want to tell OpenGL how to handle when it gets passed in as an array of data. struct Vertex3f2f { Vec3f pos; Vec2f uv; } With this, the following needs to be done to upload the data to the GPU with OpenGL (and it needs to change if the vertex structure changes, where making these changes by hand every time can easily lead to myster... | |

| | | | | Someone on the cpplang Slack asks: How can I view a std::pair<T, T> as if it were a range of two Ts? That is, fill in the blank in this sample program: template<std::ranges::range R> void increment_all(R&& rg) { for (auto&& elt : rg) { elt = elt + 1; } } template<class T> auto F(std::pair<T, T>& kv) { ~~~~ } int main() { std::pair<int, int> kv = {1, 2}; increment_all(F(kv)); assert(kv.first == 2 && kv.second == 3); std::ranges::fill(F(kv), 4); assert(kv.first == 4 && kv.second == 4); } | |
