Crate render

Original immediate/retained renderer and platform ABI. Game code, input, geometry and scheduling live in Rust; hosts only bind OS events and GPU submission.

Modules

canvas

Aspect-preserving 2D canvas with one coordinate transform for drawing and input.

demo

Shared native smoke-run support for small interactive examples. Each game supplies its own autoplay inputs and uses the same simulation as a human.

input

Input arrives in logical display pixels on every host.

mesh

Reusable geometry with face normals for lit 3D scenes.

native

Original native platform bridge. Linux uses the system X11/GLX/OpenGL APIs directly. Vertices are homogeneous clip-space XYZW followed by straight RGBA; each batch is triangles. A single streamed GPU vertex buffer and shader program persist for the window lifetime. No third-party Rust crate or windowing implementation is used here.

prelude

retained

Retained low-poly geometry and ordered instanced draw recording.

shaders

Original built-in vertex lighting and distance fog.

telemetry

Opt-in local performance recordings. Durations are CPU wall time, never inferred GPU time.

ui

Quiet, readable overlay helpers shared by the examples.

visibility

Conservative transformed-bound visibility and per-object hysteretic LOD.

Macros

Batch

Camera2D

Camera3D

Color

Unpremultiplied RGBA floating-point channels. No implicit gamma conversion.

Conf

Font

Mat4

Column-major 4x4 matrix acting on column vectors: translation * rotation * scale.

Mesh

Quat

Quaternion stored as vector part (x,y,z) followed by scalar part w.

Rect

Axis-aligned 2D rectangle. Width and height should be nonnegative.

Submit an immutable mesh snapshot. Compatible adjacent draws share one instanced call. Returns false when culled, for invalid transforms or a full frame instance budget.
