A command-line interface and web-based UI for generating VTK visualization code
using Large Language Models (Anthropic Claude, OpenAI GPT, NVIDIA NIM, and local
models).

![Screenshot from 2025-06-11 19-02-00](https://github.com/user-attachments/assets/2e1e85c3-4efd-43e4-810c-185b851d609d)

## Features

- Multiple LLM providers: Anthropic Claude, OpenAI GPT, NVIDIA NIM, and local
  models
- Interactive web UI with live VTK rendering
- Context-enhanced generation via [vtk-mcp](https://github.com/Kitware/vtk-mcp): semantic search over VTK examples and docs, class API lookup, and full code validation
- Real-time visualization of generated code
- Token usage tracking and cost monitoring
- CLI and Python API for integration

## Installation

### From PyPI (Stable)

```bash
# pip
pip install vtk-prompt

# uv (recommended)
uv pip install vtk-prompt
```

### From TestPyPI (Latest Development)

```bash
pip install -i https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ vtk-prompt
```

### From Source

```bash
git clone https://github.com/vicentebolea/vtk-prompt.git
cd vtk-prompt

# pip
pip install -e .

# uv
uv pip install -e .
```

## Quick Start

### 1. Set up API keys

```bash
export ANTHROPIC_API_KEY="your-anthropic-key"
export OPENAI_API_KEY="your-openai-key"  # Optional
```

### 2. Launch Web UI (Recommended)

```bash
vtk-prompt-ui
```

Access the UI at `http://localhost:8080`

### 3. Or use CLI

```bash
# Generate VTK code
vtk-prompt "Create a red sphere" -t $ANTHROPIC_API_KEY

# With vtk-mcp for context-enhanced generation
vtk-prompt "Create a sphere with custom resolution" --mcp-url http://localhost:8000 -t $API_KEY

# Different providers
vtk-prompt "Create a blue cube" --provider openai -t $OPENAI_API_KEY
vtk-prompt "Create a cone" --provider nim --token YOUR_NIM_TOKEN
```

## Usage

### Web UI Features

The web interface provides:

- Model selection: Choose between Claude models (Haiku, Sonnet 4) and other
  providers
- Token control: Adjust maximum tokens for responses
- Usage tracking: Real-time display of input/output tokens and costs
- vtk-mcp integration: Enter a vtk-mcp server URL to enable context retrieval and code validation
- Live preview: See VTK visualizations rendered in real-time
- Code export: View, edit, and copy generated VTK code
- Local & cloud support: Both cloud APIs and local model endpoints

### Command Line Interface

```bash
# Basic usage
vtk-prompt "Create a red sphere" -t $API_KEY

# Advanced options
vtk-prompt "Create a textured cone with 32 resolution" \
  --provider anthropic \
  --model claude-opus-5 \
  --max-tokens 4000 \
  --mcp-url http://localhost:8000 \
  --verbose \
  -t $API_KEY

# Using different providers
vtk-prompt "Create a blue cube" --provider openai --model gpt-4.1 -t $OPENAI_API_KEY
vtk-prompt "Create a cylinder" --provider nim --model meta/llama-3.3-70b-instruct -t $NIM_KEY
```

### vtk-mcp Integration

Context-enhanced generation is powered by [vtk-mcp](https://github.com/Kitware/vtk-mcp), a local
MCP server that exposes VTK knowledge tools to the LLM.

1. **Start vtk-mcp** (see its README for setup):

```bash
docker compose up   # or: uvicorn vtk_mcp.transport.http:app --port 8000
```

2. **Use with vtk-prompt**:

```bash
vtk-prompt "Create a vtkSphereSource with texture mapping" --mcp-url http://localhost:8000 -t $API_KEY
```

When `--mcp-url` is set the LLM has access to all vtk-mcp tools during generation
(class lookup, method signatures, import validation, semantic search) and the generated code
is validated against the VTK API with `validate_vtk_code` before being returned.

### Python API

```python
from vtk_prompt import VTKPromptClient

client = VTKPromptClient()
code = client.generate_code("Create a red sphere")
print(code)
```

## Model Configuration

**Model configuration with YAML prompt files:**

```yaml
# Model and parameter configuration
model: anthropic/claude-opus-5
modelParameters:
  temperature: 0.2
  max_tokens: 6000
```

**Using custom prompt files:**

```bash
# CLI: Use your custom prompt file
vtk-prompt "Create a sphere" --prompt-file custom_vtk_prompt.yml

# CLI: Or with additional CLI overrides
vtk-prompt "Create a complex scene" --prompt-file custom_vtk_prompt.yml --retry-attempts 3

# UI: Use your custom prompt file
vtk-prompt-ui --server --prompt-file custom_vtk_prompt.yml
```

### Model Parameters Guide

**Temperature Settings:**

- `0.1-0.3`: More focused, deterministic code generation
- `0.4-0.7`: Balanced creativity and consistency (recommended)
- `0.8-1.0`: More creative but potentially less reliable

**Token Limits:** Token usage can vary significantly between models and
providers. These are general guidelines:

- `1000-2000`: Simple visualizations and basic VTK objects
- `3000-4000`: Complex scenes with multiple objects
- `5000+`: Detailed implementations with extensive documentation

_Note: Different models have different token limits and costs. Check your
provider's documentation for specific model capabilities._

## Testing

```bash
# Run all tests with tox
tox -e test

# Or directly with pytest (pip or uv)
pip install -e ".[test]" && pytest
uv pip install -e ".[test]" && pytest
```

## Configuration

### Environment Variables

- `ANTHROPIC_API_KEY` - Anthropic Claude API key
