Syntax
class IStereoRenderTargetManager
Remarks
The IStereoRenderTargetManager can be returned from IStereoRendering::GetRenderTargetManager() implementations. Implement this interface if a stereo rendering device requires all output to be rendered into separate render targets and/or to customize how separate render targets are allocated.
Functions
| Type | Name | Description | |
|---|---|---|---|
  |
int32 | Acquires the next available color texture. | |
  |
bool | AllocateDepthTexture
(
uint32 Index, |
Allocates a depth texture. |
  |
bool | AllocateRenderTargetTextures
(
uint32 SizeX, |
Allocates the render target textures, which includes the color textures and optionally other textures like depth. |
  |
bool | AllocateShadingRateTexture
(
uint32 Index, |
Allocates a shading rate texture. |
 |
void | CalculateRenderTargetSize
(
const FViewport& Viewport, |
Calculates dimensions of the render target texture for direct rendering of distortion. |
   |
EPixelFormat | Returns pixel format that the device created its swapchain with (which can be different than what was requested in AllocateRenderTargetTexture) | |
  |
EPixelFormat | ||
  |
bool | HDRGetMetaDataForStereo
(
EDisplayOutputFormat& OutDisplayOutputFormat, |
Retrieves HDR information about the stereo device, if any is available. |
  |
bool | NeedReAllocateShadingRateTexture
(
const TRefCountPtr< struct IPooledRenderTarget >& ShadingRateTarget |
Returns true, if shading rate texture must be re-calculated. |
 |
bool | NeedReAllocateViewportRenderTarget
(
const FViewport& Viewport |
Returns true, if render target texture must be re-calculated. |
  |
bool | ReconfigureForShaderPlatform
(
EShaderPlatform NewShaderPlatform |
In the editor, we may switch between preview shader platforms, which support various single-pass rendering methods (e.g. InstancedStereo or MobileMultiView). |
  |
bool | Whether a separate render target should be used or not. | |
 |
void | UpdateViewport
(
bool bUseSeparateRenderTarget, |
Updates viewport for direct rendering of distortion. Should be called on a game thread. |
Deprecated Functions
| Type | Name | Description | |
|---|---|---|---|
  |
bool | AllocateRenderTargetTexture
(
uint32 Index, |
Implement AllocateRenderTargetTextures to allocate all textures at once |
   |
uint32 | Inferred from the array size returned in AllocateRenderTargetTextures | |
  |
bool | NeedReAllocateDepthTexture
(
const TRefCountPtr< struct IPooledRenderTarget >& DepthTarget |
Return true in NeedReAllocateViewportRenderTarget instead |
