3d-molecule-ray-tracer-1（3d 分子射线示踪剂 1）

3D Molecule Ray Tracer

Advanced molecular visualization tool that generates professional-grade rendering scripts with cinematic effects for creating publication-quality and cover-worthy molecular images.

When to Use

• Use this skill when the task is to Generate photorealistic rendering scripts for PyMOL and UCSF ChimeraX.
• Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
• Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

Key Features

See ## Features above for related details.

• Scope-focused workflow aligned to: Generate photorealistic rendering scripts for PyMOL and UCSF ChimeraX.
• Packaged executable path(s): scripts/main.py.
• Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

Example Usage

See ## Usage above for related details.

cd "20260318/scientific-skills/Data Analytics/3d-molecule-ray-tracer"
python -m py_compile scripts/main.py
python scripts/main.py --help

Example run plan:

1. Confirm the user input, output path, and any required config values.
2. Edit the in-file CONFIG block or documented parameters if the script uses fixed settings.
3. Run python scripts/main.py with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

Implementation Details

See ## Workflow above for related details.

• Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
• Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
• Primary implementation surface: scripts/main.py.
• Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
• Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

python -m py_compile scripts/main.py

Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

python -m py_compile scripts/main.py
python scripts/main.py --help

Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

Evaluation Criteria

Success Metrics

• [ ] Successfully generates valid PyMOL/ChimeraX scripts
• [ ] Scripts execute without errors in target software
• [ ] Output images meet quality standards
• [ ] Handles edge cases gracefully

Test Cases

1. Basic Functionality: Generate script for PDB ID → Valid script created
2. File Input: Generate script from PDB file → Valid script created
3. Preset Override: Custom parameters override preset → Correct settings applied
4. Both Software: Generate for PyMOL and ChimeraX → Both scripts valid

Lifecycle Status

• Current Stage: Draft
• Next Review Date: 2026-03-15
• Known Issues: None
• Planned Improvements:

- Blender integration - AI-assisted composition suggestions - Real-time preview mode

• Colorblind-friendly palettes
• Journal submission guidelines

Limitations

• Static Images Only: Generates scripts for still images, not animations
• Software Dependency: Requires separately installed PyMOL or ChimeraX
• Rendering Time: High-quality renders can take 10-30 minutes per image
• Learning Curve: Advanced effects require understanding of photography concepts
• File Sizes: High-res images can be 10-50 MB each
• No Automatic Layout: Creates single images; figure assembly requires separate tools

💡 Tip: For creating multiple related figures, save your complete scene setup (lighting, camera, colors) as a PyMOL session file (.pse) or ChimeraX session (.cxs), then modify only the specific elements needed for each figure. This ensures consistency across figure panels.

Output Requirements

Every final response should make these items explicit when they are relevant:

• Objective or requested deliverable
• Inputs used and assumptions introduced
• Workflow or decision path
• Core result, recommendation, or artifact
• Constraints, risks, caveats, or validation needs
• Unresolved items and next-step checks

Error Handling

• If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
• If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
• If scripts/main.py fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
• Do not fabricate files, citations, data, search results, or execution outcomes.

Input Validation

This skill accepts requests that match the documented purpose of 3d-molecule-ray-tracer and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

3d-molecule-ray-tracer only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.
