render_mix · Render mix
Two-input GPU mix (factor interpolation) on the render path.
Node-Guide
render_pass · Render pass
The single-pass offscreen building block: one script, one fullscreen-triangle draw.
render_passthrough · Passthrough
Identity render: in comes out unchanged — the control node for the GPU upload/download path.
render_pipeline · Multi-pass render pipeline
Task-level pass orchestration: a passes count plus flat pass{i}_* parameter keys express the whole filter chain.
render_scharr · Render Scharr
Render-path Scharr derivative (smoothing kernel calibrated as [3,10,3]).
render_sobel · Render Sobel
Render-path Sobel (ksize 1-7); kernel coefficients computed on the CPU and sent as uniforms.
render_subtract · Saturated subtract
Saturating in - in2: the building block for morphological gradients and diff mattes.
render_threshold · Render threshold
Luminance threshold binarization on the GPU render path.
render_unsharp · USM sharpen
Unsharp mask: in = original, in2 = blurred; amount controls strength.
opencv_add_weighted · Weighted blend
Linear blend of two inputs by alpha/beta/gamma — stacking, crossfades, watermarks.
