scene(resolution = (1000, 1000))

draw(ob; resolution = (1000, 1000), kwargs...)

Draw an object in a new scene. kwargs depends on the object type.

draw the ClusterWithProperties at coordinates specified by latticecoordinateoffset

draw!([scene = currentscene], ob; kwargs...)

save(path::String)

drawtracerays(system::Q; raygenerator::S = Source(transform = Transform.translation(0.0,0.0,10.0), origins = Origins.RectGrid(10.0,10.0,25,25),directions = Constant(0.0,0.0,-1.0)), test::Bool = false, trackallrays::Bool = false, colorbysourcenum::Bool = false, colorbynhits::Bool = false, rayfilter::Union{Nothing,Function} = onlydetectorrays, kwargs...)

Displays a model of the optical system. raygenerator is an iterator that generates rays. If trackallrays is true then ray paths from the emitter will be displayed otherwise just the final rays that intersect the image detector will be shown, not the entire ray path. colorbysourcenum and colorbynhits will color rays accordingly, otherwise rays will be colored according to their wavelength.

By default only ray paths that eventually intersect the detector surface are displayed. If you want to display all ray paths set rayfilter = nothing.

Also drawtracerays! to add to an existing scene, with drawsys and drawgen to specify whether system and raygenerator should be drawn respectively.

drawtraceimage(system::Q; raygenerator::S = Source(transform = translation(0.0,0.0,10.0), origins = Origins.RectGrid(10.0,10.0,25,25),directions = Constant(0.0,0.0,-1.0)), test::Bool = false)

Traces rays from raygenerator through system and shows and returns the detector image. verbose will print progress updates.

spotdiag(sys::CSGOpticalSystem{T}, raygenerator::OpticalRayGenerator{T}; size = (500, 500), kwargs...)

Plot a spot diagram for an arbitrary CSGOpticalSystem and OpticalRayGenerator. All rays from raygenerator will be traced through sys and their intersection location on the detector plotted.

Also spotdiag! of the same arguments to add to an existing plot.

surfacesag(object::Union{CSGTree{T},Surface{T}}, resolution::Tuple{Int,Int}, halfsizes::Tuple{T,T}; offset::T = T(10), position::SVector{3,T} = SVector{3,T}(0.0, 0.0, 10.0), direction::SVector{3,T} = SVector{3,T}(0.0, 0.0, -1.0), rotationvec::SVector{3,T} = SVector{3,T}(0.0, 1.0, 0.0))

Calculates and displays the surface sag of an arbitrary Surface or CSGTree.

Rays are shot in a grid of size defined by resolution across a arectangular area defined by halfsizes. This rectangle is centred at postion with normal along direction and rotation defined by rotationvec. offset is subtracted from the sag measurements to provide values relative to the appropriate zero level.

eyebox_eval_eye(assembly::LensAssembly{T}, raygen::OpticalRayGenerator{T}, eye_rotation_x::T, eye_rotation_y::T, sample_points_x::Int, sample_points_y::Int; pupil_radius::T = T(2.0), resolution::Int = 512, eye_transform::Transform{T} = identitytransform(T))

Visualise the images formed when tracing assembly with a human eye for an evenly sampled sample_points_x × sample_points_y grid in the angular range of eyeball rotations -eye_rotation_x:eye_rotation_x and -eye_rotation_y:eye_rotation_y in each dimension respectively. resolution is the size of the detector image (necessarily square).

The eye must be positioned appropriately relative to the system using eye_transform, this should transform the eye to the correct position and orientation when at 0 rotation in both dimensions. By default the eye is directed along the positive z-axis with the vertex of the cornea at the origin.

The result is displayed as a 4D image - the image seen by the eye is shown in 2D as normal with sliders to vary eye rotation in x and y. The idea being that the whole image should be visible for all rotations in the range.

eyebox_eval_planar(assembly::LensAssembly{T}, raygen::OpticalRayGenerator{T}, eyebox::Rectangle{T}, sample_points_x::Int, sample_points_y::Int, vsize::T; pupil_radius::T = T(2.0), resolution::Int = 512)

Visualise the images formed when tracing assembly for multiple pupil positions within a planar eyebox. Any angles which are present in a circle radius pupil_radius around each sampling point on an even sample_points_x × sample_points_y grid on the eyebox are added to the sub-image at that grid point.

A paraxial lens focal length 1mm is placed at the eyebox and a detector of size vsize × vsizemm placed 1mm behind it. The normal of the detector rectangle should point towards the system (and away from the fake detector). Any rays which miss the detector are ignored.

The pupil is always fully contained in the eyebox, i.e., the extreme sample position in u would be eyebox.halfsizeu - pupil_radius, for example.

The result is displayed as a 4D image - each sub-image is shown as normal with sliders to vary eye rotation in x and y. The idea being that the whole FoV should be visible for all rotations in the range.

draw!([scene = currentscene], ob; kwargs...)
