Rotating and object from left/right and up/down movements
I'm writing a game which involves cubes. The user can rotate individual cubes, from his perspective, 90deg left, right, up or down.
Naturally as the shape is rotated, the positions of its axes change, so the next rotation might be about a different…

Rotation and Translation on Object coordinate
I'm programming a simple application in OpenGL. I have a model that I want to rotate around its center (local coordinate), then translate it along with its local coordinate, too. I've done two scenarios,
rotate then translate, and vice versa. In…

coordinate values after rotation in opengl
Say I have a cube. Say the coordinate values are like this. (1 unit an arm)
GLfloat vertA[3] = { 0.5, 0.5, 0.5};
GLfloat vertB[3] = {-0.5, 0.5, 0.5};
GLfloat vertC[3] = {-0.5,-0.5, 0.5};
GLfloat vertD[3] = { 0.5,-0.5, 0.5};

OpenGl rotate custom implementation
I'm trying to code my custom implementation of Opengl glRotatef(angle,x,y,z) function.
I wrote the rotation matrix, but when I try to use it, the effect is not the same as the original function. Here is my code;
void mglRotate(float angle, float x,…
