Web4 de dez. de 2024 · If it is true, every movement of the mouse is translated to a rotation inside the OpenGL app. For that to happen, we first have to get the current mouse position and then we use the previously stored coordinates to determine how far the mouse cursor moved between the last and the current frame. Next, both rotations get calculated … Web31 de jan. de 2024 · In order to rotate around itself, mathematically what you do is first apply a translation transformation to the cube and move its center to [0,0,0] then rotate it around y as normal then apply a second translation to move it back to [0,0,-5]. – PentaKon Feb 4, 2024 at 14:24 Add a comment You must log in to answer this question.

Web9 de jul. de 2024 · Solution 1. You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix). Note that to convert from degrees to radians, use glm::radians (degrees) That takes the Model matrix and applies rotation on top of all the operations that are already in there. Web16 de dez. de 2024 · Each time your object moves or rotates, you do: matrix = glm::translate (glm::mat4 (1), glm::vec3 (x,y,z)) * glm::rotate (glm::mat4 (1), glm::radians (ROTATION_ANGLE), glm::vec3 (choose the axis of rotation)); which is essentially TRANSFORMATION_MATRIX = TRANSLATION_MATRIX * ROTATION_MATRIX; or M …
