Member Function Documentation

◆ _setDepthBufferDefaults()

void Ogre::NULLTextureGpuRenderTarget::_setDepthBufferDefaults ( uint16  depthBufferPoolId,
bool  preferDepthTexture,
PixelFormatGpu  desiredDepthBufferFormat 

These 3 values are used as defaults for the compositor to use, but they may be explicitly overriden by a RenderPassDescriptor.

Particularly required when passing the textures between nodes as input and output (since only the TextureGpu pointer is passed, and thus this information is lost)

Changing these settings won't take immediate effect because they're only used when creating the compositor.
depthBufferPoolIdSets the pool ID this RenderTarget should query from. Default value is POOL_DEFAULT. Set to POOL_NO_DEPTH to avoid using a DepthBuffer (or manually controlling it)
preferDepthTextureWhether this RT should be attached to a depth texture, or a regular depth buffer. On older GPUs, preferring depth textures may result in certain depth precisions to not be available (or use integer precision instead of floating point, etc). True to use depth textures. False otherwise (default).
desiredDepthBufferFormatOgre will try to honour this request, but if it's not supported, you may get lower precision. All formats will try to fallback to PF_D24_UNORM_S8_UINT if not supported. Must be one of the following: PFG_D24_UNORM_S8_UINT PFG_D16_UNORM PFG_D32_FLOAT PFG_D32_FLOAT_X24_S8_UINT
