a linearity of 1 makes all the outer bounds of the shape straight.a linearity of 0 creates a disc, no matter the number of blades or the concavity.a concavity greater than or equal to number of blades degenerates the shape into a “burst pattern”.a concavity greater than number of blades - 1 but lower than number of blades turns the shape into an asterisk, when decreasing linearity below 1.a concavity greater than 1 but lower than number of blades - 1 turns the shape into a star.a concavity of 1 ensures the diaphragm is a regular convex polygon (triangle, pentagon, heptagon, etc.).If you degenerate the diaphragm settings with the concavity to create a star or an asterisk, this control defines how many branches it has. In any case, real lenses have an odd number of blades and any number greater than 11 blades comes very close to producing a perfect disc. Older lenses used typically 5 or 7 blades, newer lenses typically use 9 or 11 blades. 🔗controls specific to lens blur diaphragm blades The number of blades that the diaphragm is composed of. blur type Choose between the different blur variants (above). 🔗module controls 🔗general blur radius The spreading size of the blur. The module will turn each luminous point from the scene into a blot shaped like the displayed blurring operator, with the size of the blot defined by the blur radius. gaussian blur: This is not really an optical blur but can be used for denoising or for creative effects using blend modesĪ diagram at the top of the module shows the shape of the blurring operator (known as the point spread function).motion blur: Simulates the effect of camera motion with a configurable path.lens blur: Simulates a lens diaphragm with a configurable number of blades and blade curvature to create synthetic bokeh.Simulate physically-accurate blurs in scene-referred RGB space.
