Class MipsUploadAdmission

Namespace

LansMap.Core.TileCache

Caps mip-chain tile uploads per frame at the slower flat-path rate (FlatSubmitMsPerTile) because mips-on GPU-decode submission is cheaper on the stopwatch and would otherwise admit more tiles. The pipeline uses this; most apps never call it.

public static class MipsUploadAdmission

Inheritance

object

MipsUploadAdmission

Fields

FlatSubmitMsPerTile

Flat-path (no mips) GPU-decode submission cost in milliseconds per 512 px tile. The mips-on cap is derived from this number.

public const double FlatSubmitMsPerTile = 0.0638

Field Value

double

Methods

MaxUploadsPerFrame(double)

Largest number of mips-on uploads one frame may admit at uploadBudgetMs.

public static int MaxUploadsPerFrame(double uploadBudgetMs)

Parameters

uploadBudgetMs double

Main-thread upload budget in milliseconds.

Returns

int

Floor of budget divided by FlatSubmitMsPerTile, at least 1 for any positive budget, and 0 for a non-positive budget.
