3d simulation of a rolling ball

Click For Summary
SUMMARY

This discussion focuses on simulating a golf ball rolling on a green using 3D scanning technology. The user seeks advice on software tools to model the ball's path from various positions on the green, aiming for a path accuracy of 5-10%. Key considerations include the accurate mapping of the green using a 3D scanner and calculating the friction of the grass, although factors like wind speed are acknowledged as difficult to incorporate. The conversation emphasizes the importance of understanding golf mechanics to enhance the simulation's effectiveness.

PREREQUISITES
  • 3D scanning technology for accurate terrain mapping
  • Understanding of physics principles related to friction
  • Basic knowledge of golf mechanics and putting techniques
  • Familiarity with simulation software tools
NEXT STEPS
  • Research 3D modeling software such as Blender or Unity for simulation development
  • Explore methods for calculating grass friction coefficients
  • Learn about physics engines like PhysX or Bullet for realistic motion simulation
  • Investigate existing golf simulation tools for benchmarking
USEFUL FOR

This discussion is beneficial for software developers, engineers, and golf enthusiasts interested in creating realistic golf simulations and improving their understanding of the physics involved in putting.

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!

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
