Inside the renderer
Technical documents for the native modes: follow the estimator, the measurement pipeline and the limits of the implementation.
Photon transport
From analytical supports to mesh sheets and surface receivers.
Hourglass + disk through glass
A bounded native comparison on the same light–glass–single-scatter paths: rotational hourglass, refracted meridian disk and their balance mixture.
Read the technical document →Two charts, one refracted chain
What the disk actually sweeps, why a plane need not add a bounce, and how the two charts meet on a common path measure.
Read the technical document →The rendering frontier, inside RadianceLab
Restricted native rotational and three-scatter sheet estimators, plus an isolated visibility-cache experiment.
Read the technical document →Experimental receivers: from support to image
Sampling stripes, coherent fringes and sharp boundaries: connect a geometric construction to an actual receiver image.
Read the technical document →Two spheres, one scattering connection
A residual circle becomes a single-scattering radiance estimator, checked against independent camera-ray quadrature.
Read the technical document →Sharp support, signed receiver curves
Move a collimated source and integrate its zero-width boundary derivative over finite film pixels. Compare against displaced images.
Read the technical document →Surface receiver curves
Angular photon sheets meet actual scene surfaces. Inspect the measure, supported path class and stochastic versus quadrature routes.
Read the technical document →Cone + plane: what the pair buys
Equal marginal path densities, different within-sheet correlations: understand the balance weights before comparing native results.
Read the technical document →Caustics from dielectric meshes
Numerical sheets through real glass meshes, including the geometry and topology cuts behind the result.
Read the technical document →A fast caustic viewfinder
A deliberate approximation for revealing caustic structure quickly; compare it with the numerical sheet route.
Read the technical document →Surfaces, time slices & derivatives
Native receiver curves, residual intersection dimensions, finite temporal kernels and translated-light differences.
Read the technical document →From supports to coherent fields
Controlled surface-footprint derivatives and scalar FFT wave propagation, with their assumptions kept visible.
Read the technical document →Collision, track length & ratio tracking
Three estimators of related medium integrals: what is sampled and which exponential factors cancel.
Read the technical document →Custom primitive combinations
Common-measure MIS within the kernel-free group and an explicit blend for finite-radius curves.
Read the technical document →Emitter size and angular profile
Compare complementary strategies on controlled source sizes and emission distributions.
Read the technical document →Cameras & measurement
Acquire a signal, reconstruct depth, or turn a viewfinder into a photograph.
Coherent waves on curved receivers
Compare coherent, incoherent and signed cross-term images from actual scalar fields sampled on a floor and spheres.
Read the technical document →Start a depth acquisition
One-button native acquisitions, interactive refresh and a readable breakdown of reconstruction.
Read the technical document →Projectors, phase & depth
Four-shot CW, multiple frequencies and off-axis carrier demodulation, including ambiguity resolution.
Read the technical document →A holographic photograph in the scene
What the captured view and the separate coherent replay actually reconstruct.
Read the technical document →Take a photograph
High-quality stills, camera-motion exposure, linear film export and the implemented tilt/shift lens geometry.
Read the technical document →Rendering in practice
Paired scenes, approximation choices and evidence for what each backend supports.
Record a frontier experiment
Open the native lab, choose a favorable or difficult scene, and preserve the method, settings and raw film alongside a recording.
Read the technical document →Implemented renderers and open experiments
A concrete implementation ledger: scene modes, controlled numerical experiments and the extensions that remain open.
Read the technical document →Scenes that expose a technique
Paired cameras, materials, medium and renderer settings make each technique immediately inspectable.
Read the technical document →Textured material studies
Native textured floors, material detail and scene-linear captures from the rendering workflow.
Read the technical document →The enhanced raster viewfinder
Surface guidance, medium strategies and fast caustic sheets, with approximation boundaries spelled out.
Read the technical document →Estimator support & limitations
A branch-level account of supported materials, emitters, media, path classes and known correctness gaps.
Read the technical document →CPU, GPU & temporal coverage
Why the current implementations run where they do, and what a real migration or transient extension requires.
Read the technical document →Research extensions and scope
Separate working paths, controlled research experiments and directions that still need an estimator.
