Camera non uniform bokeh support

[Dade]

The v2.5 branch has now the support for camera non uniform bokeh (from issue https://github.com/LuxCoreRender/LuxCore/issues/409).

It can be enabled with the following camera properties:

Code: Select all

# Number of camera blades (must be > 3 to enable bokeh)
scene.camera.bokeh.blades = 6
# NONE, UNIFORM, EXPONENTIAL, INVERSEEXPONENTIAL, GAUSSIAN, INVERSEGAUSSIAN or TRIANGULAR
scene.camera.bokeh.distribution.type = EXPONENTIAL
# Distribution power, 0 or more, affects only EXPONENTIAL and INVERSEEEXPONENTIAL distributions
scene.camera.bokeh.power = 0
# For anamorphic bokeh, the scale vector is normalized (so the length doesn't matter)
scene.camera.bokeh.scale.x = 1
scene.camera.bokeh.scale.y = 1

They affects only perspective cameras.

It can produce many types of bokeh effects:

Old LuxRender wiki has a quite comprensive explanation of bokeh: https://web.archive.org/web/20161014045 ... ld_of_View

Is it possible to create an oval aperture for anamorphic bokeh?

Is it possible to create an oval aperture for anamorphic bokeh?

I can add an option for anisotropic bokeh

Awesome ! 2.5 will be famous

Nice feature, thanks Dade! On the subject, some renderers can make use of an "aperture map", an image texture providing the bokeh shape, for example to produce "heart bokeh", or simlate imperfections. Not sure how useful it is, but being able to provide a map is user friendly.

Done:

Code: Select all

scene.camera.bokeh.blades = 64
scene.camera.bokeh.distribution.type = UNIFORM
scene.camera.bokeh.scale.x = 1
scene.camera.bokeh.scale.y = 3

It is possible but not trivial, we can add it if there is enough demand in the future.

Thank you!

This is great, thanks a lot for your work <3 Can't wait B.Y.O.B. to enable this feature in BlendLuxCore in some "pre-alpha 2.5" build
