FIN OS is an Open Source fin creation tool for Garry's Mod created by ravo Norway 28. March 2021 over three days.

FIN OS Tool (FIN OPEN SOURCE)

FIN OS Tool on Steam Workshop

You can find the stand alone tool under: Weapons => Tools => Fin OS Tool

Made from scratch, and based on the modern lift/drag equations: https://wright.nasa.gov/airplane/lifteq.html & ( https://www.grc.nasa.gov/www/k-12/airplane/sized.html, https://www.grc.nasa.gov/www/k-12/airplane/dragco.html, https://www.grc.nasa.gov/www/k-12/airplane/drageq.html, https://www.grc.nasa.gov/www/k-12/airplane/presar.html )

Quick start:

Left-Click to add two vector points for the forward direction vector. (this should normally be in the direction the creations forward reference is) After that, create the area of the fin. Done. You can also add a flap if you want with ( IN_USE + Left-Click ) on a fin and prop. Reload will remove fin and flap, or flap. Right-Click will track selected fin (real-time physics). ( IN_USE + Sroll Wheel ) will increase/decrease the scalar value of the fin you are looking at. The server admin can adjust server settings with the console variables underneath.

How to use:

• You can find the stand alone tool under: Weapons => Tools => Fin OS Tool
• Left-Click to apply 3 - 26 local origo originated vector points on prop, to get started. This will calculate the area using .5 the length of the cross product for all the triangles
• ( IN_USE + Left-Click ) to add a flap. Connect by clicking on the fin/flap and on the flap/fin
• Right-Click to add fin to tracked fin table
• Reload to remove fin/flap from prop
• ( IN_USE + SCROLL_WHEEL ) to increase the scalar value. Look at the fin you want to scale up/down
• ( IN_USE + MIDDLE_MOUSE ) to open the client settings panel

How it works:

• It uses real physics to calculate lift from the center of the prop, and real life formula for calculating lift: Force[LIFT] = .5 * rho[AIR] * Velocity[m/s]^2 * Area[m^2] * C[L - angle of attack] - also about uses the same logic for the drag

Features:

• Supports duplication
• Supports clean up
• Supports SBOX max
• Some ConVar settings
• Advanced validity checking of area ( when finos_disablestrictmode == 0 )
• Supports Wiremod input/output ( Physics => FIN OS Tool )

@todo

• Make a custom world model for the fin tool SWEP
• Fix bones, so it will the Players custom player model
• Small issue with props having different angles ( over 90 degrees ) - compensated for that [ DON'T THINK THIS IS AN ISSUE ANYMORE ]
• Make the strict mode better ( ? )
