3d simulation of a rolling ball

AI Thread Summary
The discussion focuses on simulating a golf ball rolling on a green using data from a 3D scanner. The goal is to model the putting path and determine optimal aiming points, with an accuracy target of 5-10%. While factors like wind speed may be disregarded, grass friction will be a key variable to calculate for realistic results. Participants suggest that practical golf experience could enhance the simulation's effectiveness. The conversation emphasizes the importance of understanding both the technical and experiential aspects of golf for accurate modeling.

Hi,

I'm looking for advice on how to simulate a golf ball rolling on a green. The green will have been scanned using a 3d scanner by an Engineering Surveyor. I'm trying to model putting a golf ball from any position on the green, looking for a path line to the hole, and where to aim.
For example, aim 3 ft to the left and 2 ft short (assuming there is a slope left-to-right and slightly downhill).

Any advice on the type of software and how to do it, would be appreciated.

Welcome to the PF. :smile:

How much golf have you played? How can you incorporate what you know from your time on the courses into this type of simulation? How accurate do you want this to be, and what variables do you think you should consider to try to achieve that level of accuracy?
 
using a 3d scanner, the green can be mapped pretty accurately, within a few mm. I want the putt path to be fairly accurate within 5 or 10%. It's more of a guide than an exact. Things like wind speed probably can't be taken into consideration, but friction of the grass can be calculated, so the accuracy won't be fullproof. but hopefully pretty close
 
Okay, so you've never actually played golf or putted greens. That's okay, but it will limit your thinking on this a bit. Maybe it's time to head to the local par-3 course for some research... :wink:

How are you going to calculate the "friction" of the grass on the greens?
 
Not sure yet. looking for recommendations

Sorry, yes I'm played golf for years. and wasted many putts in the process!

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
