can someone help show me an example on how to use quaternion slerp to displace the position 64,0,0 in the Z direction by 167 and rotate 10 degrees? Ive seen many many papers that show: [cos(Θ/2),nsin(Θ/2)][0,0,0,0]∗[1,0,0,0][0,tx/2,ty/2,tz/2] and the formula to multiply these 2...

Wow, thats exactly what I needed. thank you! I appreciate the breakdown that really helps. very nice. thank you.

Yea I did the same search, just had a hard time following those examples. First one starts out with Pn which I wasn't really sure what that was I didn't see an n in the example.

Wow, thank you. Can you show me how you did it. I would like to learn. Thank you

Its a long story - its not related to carpentry or home work. Im trying to calculate the position 1/2" up perpendicular to an angled surface so I know where to locate a piece of equipment automatically. I know the coordinates of 2 points on that angled surface. Im affraid trying to adequately...

its a right triangle abc. point a coordinates = (1,7) point b coordinates = (2,3) length ab = 4.12 length bc = .5 angle b is 90° is it not possible to calculate the coordinates for point c from the given information?

I would be interested in learning how to calculate the 3rd missing set if coordinates of a right triangle using whichever example is best. The example I presented represents the triangle I need to calculate for but if there is a better way to learn I am very interested. Thank you

I probably need more than classroom help..... Yes .89 is way off It should have been 4.12 i apologize. Thanks for your time.

Correct.... I am an idiot. I did present a bad example. .89 is way off, not sure what I was thinking. It's been a long day. ab = 4.12 bc = .5 I appreciate all the help. What is the next step to find the x,y of c? Thanks again for your input.

so I came up with √(2-1)² + (3-7)² √(1)² + (-4)² √1 + 16 √17 4.12 does this look correct? thank you!

I wasnt really sure where to start. .89 may not be correct I just sketched my example on some graph paper and it looked to be a hair under .9 No I havnt learned about slopes. is that a good place to start? thank you for your help.

Im trying to find the 3rd set of coordinates when I know the other two coordinates and I know the lengths of 2 sides - example: If I had a right triangle "a,b,c" and I know angle b is 90°, I know the length of ab is .89, I know the length of bc is .5, I know the coordinates of a are (1,7)...

Thank you for the reply. What if the circle was a fixed diameter?

how do I calculate the origin of a circle along a horizontal plane where the circle contacts an arc.... see this picture - if I know the (x,y) of points 1, 2 & 3 and I know the (x,y) of any point along the arc and I know the diameter of the circle is it possible to calculate the (x,y) of the...
