I’m trying to modify the mouse-modes demo so that the mouse rotates the box in a more intuitive manner.
Currently, moving the mouse rotates the box along it’s own heading and pitch, however I would like the mouse to rotate things along a global heading and pitch. Pretty much, moving the mouse up will always rotate the box upwards relative to the camera. Illustrative picture attached.
I mainly need help figuring out how to turn a delta in screen X and Y to the modified HPR values. The original code is :
self.rotateX += dx * 10 * self.mouseMagnitude self.rotateY += dy * 10 * self.mouseMagnitude self.model.setH(self.rotateX) self.model.setP(self.rotateY)
Which I know I have to modify something to adjust for all three rotation angles. I’ve taken out a global rotation like this, but have no idea how to get the desired result:
hpr = self.model.getHpr() self.model.setHpr(hpr + dx*10*self.mouseMagnitude, hpr + dy*10*self.mouseMagnitude, 0)
Any help with either translating to a correct dh,dp,dr, or using a panda API function would be great
