picogl.backend.gl.driver.raster

GLRaster Driver

Cached write-only raster state. Imperative setters implement gl calls; apply(RasterState) diffs frozen snapshots and is the preferred API.

Classes

GLRasterDriver

Fixed-function raster state with write-only gl and cached current values.

Functions

resolve_polygon_mode_args(→ tuple[Any, Any])	Normalize set_polygon_mode overloads to (face, mode).
_gl_set_polygon_mode(→ None)	Issue a raw glPolygonMode call without touching driver cache.
shared_raster_driver(→ GLRasterDriver | None)	Backward-compatible alias for GLRasterDriver.shared().

Module Contents

picogl.backend.gl.driver.raster.resolve_polygon_mode_args(*args: Any) → tuple[Any, Any]

Normalize set_polygon_mode overloads to (face, mode).

picogl.backend.gl.driver.raster._gl_set_polygon_mode(face_val: int, mode_val: int) → None

Issue a raw glPolygonMode call without touching driver cache.
