WebFor example glm::mat3_to_mat4 (m) will convert the 3x3 matrix m to a 4x4 matrix by appending one column on the right and one row on the left. Those now row and columns are filled with 0 except for the diagonal element which is set to 1. Using one of the convert, try_convert, or convert_unchecked functions. WebJul 9, 2024 · Multiplying a matrix and a vector in GLM (OpenGL) 45,376 Solution 1 glm::vec4 is represented as a column vector. Therefore, the proper form is: glm::vec4 result = m * v; (note the order of the operands) Solution 2 Since GLM is designed to mimic GLSL and is designed to work with OpenGL, its matrices are column-major.
