I'm implementing a camera which responds to change of mouse position. It's a more question of maths than of coding but I'd like to know how to use it as well.
I have a Camera object which rotates along the Y-axis when the mouse changes its X-position. This works as intended and I can rotate around the cube I'm drawing just fine. Now I would like to implement looking up and down triggered by mouse change vertically but the X and Z-axis are relative to the camera object so I can't just rotate along the X-axis but have to combine the X and Z-axis to do this in a fluid motion.
public class Camera {
public float moveSpeed = 0.05f;
private Vector3f position, rotation;
private float oldMouseX, oldMouseY, newMouseX, newMouseY, mouseSensitivity;
public Camera () {
position = new Vector3f(0f, 0f, 0f);
rotation = new Vector3f(0f, 0f, 0f);
mouseSensitivity = 0.1f;
oldMouseX = 0.0f;
oldMouseY = 0.0f;
newMouseX = 0.0f;
newMouseY = 0.0f;
}
public Camera (Vector3f pos, Vector3f rot) {
this.position = pos;
this.rotation = rot;
mouseSensitivity = 0.1f;
oldMouseX = 0.0f;
oldMouseY = 0.0f;
newMouseX = 0.0f;
newMouseY = 0.0f;
}
public void setCursor (int x, int y) {
oldMouseX = x;
oldMouseY = y;
newMouseX = x;
newMouseY = y;
}
public Matrix4f getViewMatrix () {
Matrix4f rotateX = new Matrix4f().rotate(rotation.x * (float)Math.PI / 180f, new Vector3f(1f, 0f, 0f));
Matrix4f rotateY = new Matrix4f().rotate(rotation.y * (float)Math.PI / 180f, new Vector3f(0f, 1f, 0f));
Matrix4f rotateZ = new Matrix4f().rotate(rotation.z * (float)Math.PI / 180f, new Vector3f(0f, 0f, 1f));
Matrix4f rotation = MatrixMath.mul(rotateX, MatrixMath.mul(rotateZ, rotateY));
Vector3f negPosition = new Vector3f(-position.x, -position.y, -position.z);
Matrix4f translation = new Matrix4f().translate(negPosition);
return MatrixMath.mul(translation, rotation);
}
public Vector3f getPosition() {
return position;
}
public Vector3f getRotation() {
return rotation;
}
public void update (Window window) {
if (window.isKeyDown(GLFW.GLFW_KEY_W)) {
position.x += Math.sin(Math.PI * rotation.y / 180) * -moveSpeed;
position.z += Math.cos(Math.PI * rotation.y / 180) * moveSpeed;
}
if (window.isKeyDown(GLFW.GLFW_KEY_S)) {
position.x -= Math.sin(Math.PI * rotation.y / 180) * -moveSpeed;
position.z -= Math.cos(Math.PI * rotation.y / 180) * moveSpeed;
}
if (window.isKeyDown(GLFW.GLFW_KEY_D)) {
position.x += Math.sin(Math.PI * (rotation.y - 90) / 180) * -moveSpeed;
position.z += Math.cos(Math.PI * (rotation.y - 90) / 180) * moveSpeed;
}
if (window.isKeyDown(GLFW.GLFW_KEY_A)) {
position.x -= Math.sin(Math.PI * (rotation.y - 90) / 180) * -moveSpeed;
position.z -= Math.cos(Math.PI * (rotation.y - 90) / 180) * moveSpeed;
}
if (window.isKeyDown(GLFW.GLFW_KEY_SPACE)) {
addPosition(0f, moveSpeed, 0f);
}
if (window.isKeyDown(GLFW.GLFW_KEY_LEFT_SHIFT)) {
addPosition(0f, -moveSpeed, 0f);
}
newMouseX = (float)window.getMouseX();
newMouseY = (float)window.getMouseY();
float dx = newMouseX - oldMouseX;
float dy = newMouseY - oldMouseY;
if (window.isMouseButtonDown(GLFW.GLFW_MOUSE_BUTTON_LEFT)) {
rotation.y += dx * mouseSensitivity;
}
//unPos = unPos.rotateAxis(dy * mouseSensitivity, (float)Math.cos(Math.PI * rotation.y / 180), 0f, (float)Math.sin(Math.PI * rotation.y / 180));
// rotation.x += (float)Math.cos(rotation.y * Math.PI / 180) * (dy * mouseSensitivity);
// rotation.z += (float)Math.sin(rotation.y * Math.PI / 180) * (dy * mouseSensitivity);
oldMouseX = newMouseX;
oldMouseY = newMouseY;
}
}
I don't think it's necessary to show you my Window class as the functions are quite self-explanitory. As you can see the part at the bottom that I commented out was my approach to solving the problem and at first it seemed to work but the rotating was slightly off.
I expect fluid up and down motion(that is, relative to the camera) but receive a weird rolling motion.
Any help is greatly appreciated!

Your problem is probably based aroundthe X and Z-axis are relative to the camera object. If you fixed the X, Y and Z axis in space, you could just track how far the mouse has moved from 0, 0 and apply the transformation from a static point.

rotate around x first and then y
– Alex
Jan 3 at 12:45
@alex I've tried that but the rotation still goes around the absolute X-axis and not the relative one. The Y-axis works great though
– J. Lengel
Jan 3 at 14:07
@Jason I also have absolute X, Y and Z-axes in model but I don't know how to transfer the relative rotation of the camera onto the absolute X, and Z-axes

I fixed my problem. It's strange but I have to multiply the Y-rotation matrix by the X-rotation matrix. That doesn't make sense to me but it works. Thanks for your help!

You should use a look at camera instead it's much easier and much more useful.

I fixed my problem. It's strange but I have to multiply the Y-rotation matrix by the X-rotation matrix. That doesn't make sense to me but it works. Thanks for your help!

You should use a look at camera instead it's much easier and much more useful.

Your problem is probably based around
the X and Z-axis are relative to the camera object. If you fixed the X, Y and Z axis in space, you could just track how far the mouse has moved from 0, 0 and apply the transformation from a static point.– Jason

rotate around x first and then y

@alex I've tried that but the rotation still goes around the absolute X-axis and not the relative one. The Y-axis works great though

@Jason I also have absolute X, Y and Z-axes in model but I don't know how to transfer the relative rotation of the camera onto the absolute X, and Z-axes
