What is 3d-graphics-and-rendering?

A guide for designing and reviewing the rendering system of a real-time 3D game. Rendering is the process that turns models, materials, lights, and effects into each displayed frame.

Use it to choose lighting and material methods, plan shadows and global illumination, set culling and level-of-detail budgets, and order post-processing effects.

Rendering choices affect visual style, image quality, frame rate, and memory or graphics-processing limits. Making these decisions deliberately helps avoid performance and consistency problems.

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	$0.00306	$0.01370
Opus 5.5	$0.00122	$0.00548
Sonnet 5.5	$0.00061	$0.00274
Haiku 4.5	$0.00031	$0.00137

Security

Grade A, and why

3d-graphics-and-rendering 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.

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

3D Graphics & Rendering

How a real-time engine turns geometry, materials, and lights into a frame — and which of those choices a generator can safely vary versus which must be frozen. Rendering is a pipeline of fixed stages with hard limits and hard budgets; getting the architecture and the imaging contract right up front is what keeps a 3D game both performant and visually coherent.

Tier: technical craft (→ gamestack-core). Engine-agnostic rendering principles every real-time 3D (or 2D with lighting) game obeys.

When to use this

Choosing the lighting architecture (forward / deferred / forward+/clustered) and living with its constraints
Picking a PBR workflow (metallic/roughness vs specular/glossiness) or deliberately departing into stylized/NPR
Selecting a GI approach (baked lightmaps · light probes · voxel/SDF GI · ray-traced) by scene dynamism and budget
Tuning shadows (slope-scaled bias, cascaded shadow maps) out of the acne↔peter-panning band
Setting performance budgets: culling, LOD, batching/instancing, overdraw — after diagnosing CPU- vs GPU-bound
Ordering the post chain (HDR effects → tonemap → LDR grade) and freezing the exposure/tonemap/AO/AA contract
Deciding which rendering parameters a generator may vary vs which are a fixed pipeline contract

Scope

This skill owns the pipeline, lighting, performance, and imaging layer — how the frame is assembled, not what's painted into it. Adjacent concerns live in sibling skills:

Material & VFX authoring: the shader model, node-graph/procedural materials, particles, decals, screen-space effects, stylization mechanics → shaders-and-vfx (this skill picks deferred-vs-forward and the overdraw budget; that skill authors the materials and effects living inside it)
Visual readability, silhouette, signal color, readability-over-fidelity → art-direction-and-readability
Generated meshes, terrain, noise, marching cubes, mesh topology correctness, scatter placement → procedural-geometry (this skill renders what that skill generates; the mesh-validity contract is shared)
Animation/skinning/blend systems → animation-systems

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.
