- vec3: length divides by the largest component before squaring, so a camera 1e200 away keeps a finite near plane; unit_cross normalizes each edge first, so edges of very different sizes keep their normal. - render: MAX_RENDER_WORK (2^31) caps the pixel centres one render tests, charged per triangle's clipped bounding box before scanning; past it, RenderError::TooMuchWork. - Bounds::centre halves each end before adding, finite for any finite box. Bounds::of and fit_meshes use only corners of triangles render draws. Camera::frame builds its basis from the direction, not from points near the model, so a small model far from the origin fits. Each new test fails with its fix reverted. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SqmHYx8FiWM5PcsoiErgp9

//! Headless CPU rendering of PRC 3D models (ISO 14739-1) to an RGBA image.
|
|
//!
|
|
//! Layer L3: depends only on `pdfcraft-prc`. [`assemble`] turns a parsed [`pdfcraft_prc::PrcFile`]
|
|
//! into world-space meshes; [`render`] draws them from a [`Camera`] with one depth-tested sample per
|
|
//! pixel centre and a light at the camera. Single-threaded and GUI-free, so it runs unchanged on wasm32.
|
|
//! The image size is capped by [`MAX_RENDER_PIXELS`], the drawing work by [`MAX_RENDER_WORK`] and the
|
|
//! assembled model by [`MAX_ASSEMBLED_TRIANGLES`] and [`MAX_ASSEMBLED_VERTICES`]; bad input is an
|
|
//! error, never a panic.
