Detailed Description

One UBO sourced from an upstream Buffer port (uniform_input).

Bound via QRhiShaderResourceBinding::uniformBuffer (std140) rather than the SSBO bufferLoad/bufferStore used for storage_input.

Public Attributes
std::string	name
QRhiBuffer *	buffer {}
bool	owned {false}
	Always false for now: borrowed from upstream.
bool	adopted {false}
	Holds a RenderList::adoptBuffer reference on buffer
bool	from_port {false}
	buffer was borrowed through the Buffer input port
int	binding {-1}
QRhiShaderResourceBinding::StageFlags	stages {}
int	input_port_index {-1}
int64_t	offset {0}
int64_t	size {0}
QString	refused
	See GraphicsSSBO::refused.
int64_t	declared_size {}
int64_t	min_size {}
	The smallest buffer that can back it: minimumUniformBlockSize (U42).

Member Data Documentation

declared_size

int64_t score::gfx::GraphicsUBO::declared_size {}

std140 size of the block the shader declares, from the LAYOUT alone. Independent of any upstream buffer, so the placeholder allocated for a never-connected input still covers everything the shader reads.

offset

int64_t score::gfx::GraphicsUBO::offset {0}

The published range of a borrowed buffer (shader board U42); size 0 means to its end.
