WebFPS camera handling is based on two angles a horizontal and a vertical one. You add your mouse x and y deltas to the angles, then each frame you just need to make a rotation matrix around X using the vertical angle, and a rotation matrix around Y using the horizontal angle and multiply them together. In OpenGL matrix stack notation: Webvoid Render() { radians = float(PI*(angle-90.0f)/180.0f); // calculate the camera's position cameraX = lookX + sin(radians)*mouseY; // multiplying by mouseY makes the cameraZ = …
