5038ed8270basic_intersect for DiskShape computed the plane hit with interval arithmetic where pbrt uses a scalar (shapes.h: Float tShapeHit = (height - Float(oi.z)) / Float(di.z)). It produced NaN, and since every NaN comparison is false neither the t range test nor the subsequent dist2 > radius^2 test could reject it. The disk reported a hit on every ray tested against it, and the NaN reached dpdu/ dpdv, the shading normal, and the area-light MIS pdf.

a14960562cThis commit is way too large. So, added Upload trait back again, but only for Textures, which are the most complex types. Fixing Medium and PixelSensor creation on host side. Can´t really find a satisfying way of keeping construction and creation separate, so for now, regrettably, putting them in the same place. Added some types to parameter parsing.

731a37abaeMore fixes to allow for spirv compilation. Namely, issues with array initialization with functions ([object::default()]), initializing arrays from a function (implemented a simple gpu version using manual MaybeUninit pointers), changing enums with distinct types to structs or changing the selection logic, changing pointer subtraction in light samplers to a scan (this will come back to bite me in the ass), and ignoring the data module, since SPIR-V cant use pointers in statics.Wito Wiala2026-02-20 21:10:36 +0000
