ao clj

(ao k falloff steps)

f - distance field p - current position n - normal k - scaling factor (0.01-1.0) falloff - 0.5-0.95 steps - how many steps (2-10)

camera clj

(camera ro ch rot)

create camera function.

• ro - ray origin
• ch - camera heading
• rot - camera rotation returns function which should be used to determine ray direction, based on pixel position

distance-fog clj

(distance-fog fcol factor)

interpolate-material clj

(interpolate-material m1 m2 amt)

(interpolate-material m1 m2 amt f)

light clj

(light L scene diff-color spec-color astr)

make-normal clj

(make-normal f eps)

material clj

(material conf)

Create material information:

• color - Vec3 with RGB: 0.0-1.0
• diffusion - diffusion ratio: 0.0 - 1.0
• specular - specular ratio: 0.0 - 1.0
• specularf0 - f0, intensity ratio: 0.0 - 1.0
• specularpow - strength of specular: 1.0 - 10k
• reflection - reflection ratio: 0.0 - 1.0

normal clj

(normal eps f p)

op-blend clj

(op-blend fs k)

(op-blend f1 f2 k)

op-displace clj

(op-displace f dispf scalein scaleout)

op-interpolate clj

(op-interpolate f1 f2)

(op-interpolate f1 f2 amount)

(op-interpolate f1 f2 amount lerp)

op-intersect clj

(op-intersect f1 f2)

op-repeat clj

(op-repeat f c)

op-rotate clj

(op-rotate f axis angle)

op-scale clj

(op-scale f s)

op-subtract clj

(op-subtract f1 f2)

op-transform clj

(op-transform f t)

op-union clj

(op-union fs)

(op-union f1 f2)

primitive clj multimethod

ray clj

(ray ro rd t)

ray-marching clj

(ray-marching scene background tmin tmax steps)

(ray-marching scene background tmin tmax steps stepf precision)

depth field ray marching tmin - starting distance > 0.005 tmax - final distance steps - how many steps stepf - step factor (0.1-1.0) precision - how close is enough (0.0001 - 0.01) background - background material returns vector, where index:

• 0 - HitData
• 1 - fake AO based on steps made

reflect clj

(reflect I N)

soft-shadow clj

(soft-shadow k steps max-depth)

vzero clj
