struct FMipBiasFade
Remarks
Functionality for fading in/out texture mip-levels.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
float | BiasOffset | Difference between total texture mipcount and the starting mipcount for the fade. |
 |
float | MipCountDelta | Number of mip-levels to fade (negative if fading out / decreasing the mipcount). |
 |
float | MipCountFadingRate | Number of seconds to interpolate through all MipCountDelta (inverted). |
 |
float | StartTime | Timestamp when the fade was started. |
 |
float | TotalMipCount | Number of mip-levels in the texture. |
Constructors
| Type | Name | Description | |
|---|---|---|---|
 |
FMipBiasFade () |
Default constructor that sets all values to default (no mips). |
Functions
| Type | Name | Description | |
|---|---|---|---|
  |
float | CalcMipBias () |
Calculates the interpolated mip-bias based on the current time. |
  |
bool | IsFading () |
Checks whether the mip-bias is still interpolating. |
 |
void | SetNewMipCount
(
float ActualMipCount, |
Sets up a new interpolation target for the mip-bias. |
