A reference for Orkid's DrawingInterface, a graphics API for drawing lines and 2D or 3D rectangles and images. It covers screen-space rendering helpers and Python bindings.

Use it to draw lines, screen-space quads, fullscreen quads, tiled quads, and other 2D graphics.

It helps developers use the project's existing drawing functions for overlays, user interfaces, post-processing, and visual debugging.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.01183
Opus 5.5	$0.00027	$0.00473
Sonnet 5.5	$0.00014	$0.00237
Haiku 4.5	$0.00007	$0.00118

Security

Grade A, and why

orklev2-dwi scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Orkid DrawingInterface (DWI) Reference

When answering questions about 2D drawing, screen-space quads, or line rendering in orkid, consult the files below. All under ork.lev2/.

Key Files

Component	File
DWI Interface	`inc/ork/lev2/gfx/dwi.h` (lines 9–56)
Vulkan DWI	`src/gfx/vulkan/headers/vulkan_ctx.h` (lines 139–142)
Python Bindings	`pyext/src/pyext_gfx.cpp` (lines 298–322)

DWI Interface (dwi.h:9–56)

The DrawingInterface provides methods for rendering 2D/3D quads and lines, primarily used for post-processing, UI overlays, and debug visualization.

Line Drawing

line2DEML(v0, v1, vertex_color, depth) — 2D line with fvec2 endpoints and fvec4 color

2D Quad Drawing (Screen-Space)

Method	Description
`quad2DEML(quadrect, uvA, uvB, depth)`	Basic screen quad with dual UV sets
`quad2DEML2(quadrect, uvA, uvB, depth)`	Variant 2
`quad2DEMLCCL(quadrect, uvA, uvB, depth)`	CCL winding variant
`quad2D(quadrect, uvA, uvB, depth)`	Auto-winding (uses RenderingConventions)
`fullscreenQuad(uvA, uvB, depth)`	Fills entire viewport

Parameters:

quadrect — fvec4(x, y, w, h) in screen space
uvA, uvB — fvec4(u0, v0, u1, v1) UV rectangles for two texture channels
depth — Z depth value (default 0.0)

3D Quad Drawing

quad3DEML(V0, V1, V2, V3, Uv0, Uv1, Uv2, Uv3, color) — 4 fvec3 vertices with per-vertex UV and uint32 color

Advanced 2D Quad (Per-Vertex UVs)

quad2DEML(v0..v3, uvA0..uvA3, uvB0..uvB3, color, depth) — 4 fvec2 vertices, 4+4 fvec2 UVs per channel, fvec4 color

Tiled Quad Drawing

quad2DEMLTiled(quadrect, uvA, uvB, numtiles) — subdivided quad (legacy)
quadTiled2D(quadrect, uvA, uvB, numtiles) — auto-winding tiled quad

Notes

EML suffix = "Eulerian-like Materials" — direct draw, bypasses material pass management
Auto-winding methods (quad2D, fullscreenQuad, quadTiled2D) adjust vertex order based on Context::renderingConventions() to handle Y-flip differences between backends
All quad methods use the SVtxV12C4T16 vertex format internally (position + color + 2 UV sets)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

orklev2-dwi is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 2mo ago), licensed MIT. It adds 68 tokens to every session and 1,183 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
