normalWS() vec3
Returns the shading normal for the current surface point in world space.
posOS() vec3
Returns the current surface point in object space coordinates.
minCosTheta() real
Returns the minimum of the cosines of the zenith angles of the incident and exitant vectors of a ray scattering off a surface.
maxCosTheta() real
Returns the maximum of the cosines of the zenith angles of the incident and exitant vectors of a ray scattering off a surface.
intrinsicCoords() vec2
Returns the intrinsic coordinates for the intersected triangle.
objectId() int
Returns a unique integer identifier for the currently hit object.
meanCurvature() real
Return the mean curvature at the current point.
Curvature shader controlling the material colour. Red = negative mean curvature, green/blue = positive mean curvature.
