render_box_dir · Directional box blur
Parameterized directional box blur (horizontal/vertical pass).
Node-Guide
render_dilate_dir · Directional dilate
GPU separable morphological dilation (max); iterations repeat passes.
render_erode_dir · Directional erode
GPU separable morphological erosion (min).
render_gauss_dir · Directional Gaussian
Parameterized directional Gaussian: ksize ≤ 99, sigma = 0 auto-derives per the OpenCV formula.
render_gauss_h · Horizontal Gaussian (5-tap)
Built-in 5-tap [1,4,6,4,1]/16 separable Gaussian, horizontal pass.
render_gauss_v · Vertical Gaussian (5-tap)
Built-in 5-tap [1,4,6,4,1]/16 separable Gaussian, vertical pass.
render_gradient · Gradient
Generates a linear gradient with no input: tests, backgrounds, compositing plates.
render_laplacian · Render Laplacian
Render-path Laplacian (ksize 1-7).
render_lut · GPU LUT apply
Two-input LUT apply: in = image, in2 = LUT image; HALD and stripe layouts auto-detected.
render_lut_cube · .cube to LUT image
Reads a .cube 3D LUT and converts it on the CPU into a HALD LUT image (feeds render_lut’s in2).
