WebHoudini VEX, Normal Vector Rotation WebSo yes, it's the "shortest" rotation, because it doesn't perform Euler rotations, it directly figures out the axis and angle to align the vectors so to speak. Edit: to clarify, there literally only is one way to align a vector to another, as a single vector only has one direction, theres no variable to spin it around itself, that makes no sense ...

WebTransfer point normals of geo to the points. If you add point normals to the target mesh the copies will automatically inherit the normal. Take a gander at the Copy to Points entry I made when you get some time: In general, the z+ direction of the object that you're copying will face in the direction of the normal. Web-- This tells the Copy to Points node to rotate the copied geometry to face the target point normals. NOTE: If a normal is facing upwards in the y-direction, then the geometry will …
