TextureExecutionContext() [2/2]

MayaFlux::Yantra::TextureExecutionContext::TextureExecutionContext ( GpuComputeConfig  config, const std::vector< GpuBufferBinding > &  bindings, OutputMode  mode = OutputMode::SCALAR  )

inline

Construct from an explicit, fully-specified binding list.

For dispatch shapes the positional constructor's image/aux split does not fit cleanly: any combination of input image, output image, and SSBOs declared directly as GpuBufferBinding entries. mode still governs collect_gpu_outputs / collect_result; the caller is responsible for the binding list matching that mode (e.g. an OUTPUT IMAGE_STORAGE entry present whenever mode != SCALAR).

Parameters

config	Shader path, workgroup size, push constant size.
bindings	Full binding list, image and buffer entries mixed freely.
mode	Controls what collect_gpu_outputs / collect_result return.
