Function Documentation

ConvolveMatrixNativeShader()

const CompiledShaderView & donner::gpu::shader::programs::ConvolveMatrixNativeShader

(

)

Returns only the platform's native MSL or SPIR-V projection and the reflected interface.

Returns

Stable view into a process-lifetime artifact.

ConvolveMatrixShader()

const CompiledShaderView & donner::gpu::shader::programs::ConvolveMatrixShader

(

)

Returns the WGSL projection and reflected interface for matrix convolution.

The host admits positive kernel orders whose product fits the coefficient array, targets inside the kernel, and finite coefficients, bias and nonzero divisor. The shader rotates the row-major kernel by 180 degrees, supports duplicate/wrap/transparent edges and optionally preserves alpha.

Returns

Stable view into a process-lifetime artifact.
