Syntax
struct FVirtualTextureFeedbackBufferDesc
Remarks
Description of how to interpret an RHIBuffer that is being fed to the virtual texture feedback system. For example a buffer may be a simple flat buffer, or a 2D screen-space buffer with rectangles representing multiple player viewports. In the future we may also want to support append style buffers containing buffer size etc.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FIntPoint | BufferSize | Size of buffer. 1D buffers have Y=1. |
 |
int32 | NumRects | The number of rectangles to read from the buffer. |
 |
FIntRect[MaxRectPerTransfer] | Rects | Rectangles to read from the buffer. |
 |
int32 | TotalReadSize | Number of buffer elements to actually read (calculated from the Rects). |
