WebDec 3, 2024 · For satellite orbiting the Earth you don't need things like quarterions or euler angles. Just glm::rotate () to rotate the satellite each frame by a given angle - and glm::translate () to move it right away from the Earth exactly like you figured it out yourself. WebJul 18, 2012 · All code here uses the GLM math library. 1) Simple extraction If you can assume there is no scaling in the matrix, you can simply: vec3 ExtractCameraPos_NoScale (const mat4 & a_modelView) { mat3 rotMat (a_modelView); vec3 d (a_modelView [3]); vec3 retVec = -d * rotMat; return retVec; } 2) Inverse Matrix Extraction ffe in lancaster

WebOpenGL Mathematics (GLM) is a C++ mathematics library for graphics software based on the OpenGL Shading Language (GLSL) specification. GLM provides classes and functions designed and implemented with the same naming conventions and functionalities than GLSL so that when a programmer knows GLSL, he knows GLM as well which makes it really … WebI've just switched from deprecated opengl functions to using shaders and GLM math library and i'm having a few problems setting up my camera rotations (first person camera). I'll show what i've got setup so far. I'm setting up my ViewMatrix using the glm::lookAt function which takes an eye position, target and up vector ...
