Optimalization for Payload
Posted: Sun Dec 07, 2025 1:56 am
Optimizations to store angles in a single byte (with small loss +-1.4 degree precision)
Can reduce network payload, as 3 angles xyz fits in 3 bytes instead of 12 byte (floats).
Can reduce network payload, as 3 angles xyz fits in 3 bytes instead of 12 byte (floats).
Code: Select all
;Wraps around angles to keep low range (0-360) Works with integers only
;Angle 370 will be 10, angle -10 will be 350
Procedure.i wrapangle(iangle.i)
ProcedureReturn ((iangle%360)+360)%360
EndProcedure
;Converts a float angle into a single byte to reduce network payload
;this will be 4 times smaller. x,y,z angles will be 3 bytes instead of 12
Procedure.a AngleToByte(angle.f)
Protected iangle.i , aangle.a
iangle.i = Round(angle.f,#PB_Round_Nearest)
iangle.i = wrapangle(iangle.i)
aangle = Round(((iangle/360)*255),#PB_Round_Nearest)
ProcedureReturn aangle
EndProcedure
;converts byte angle back to float. +- 1.4 degree loss predicted, but can save a lot of bandwidth.
Procedure.f ByteToAngle(angle.a)
Protected fangle.f
fangle.f = ((angle/255)*360)
ProcedureReturn fangle
EndProcedure
