# Editor UI Improvements - Update Summary
|
||||
|
||||
## Overview
|
||||
|
||||
The Preset Editor has been significantly enhanced with live canvas preview, node selection, and real-time rendering capabilities.
|
||||
|
||||
## New Features
|
||||
|
||||
### 1. Live Canvas Preview
|
||||
|
||||
A real-time canvas preview has been added directly to the Editor view:
|
||||
|
||||
- **Location**: Center panel, above the layer list
|
||||
- **Display**: Shows live animation rendering at the configured FPS
|
||||
- **Updates**: Automatically refreshes when layers are added, modified, or removed
|
||||
- **FPS Counter**: Displays actual rendering frame rate
|
||||
- **Size Display**: Shows current matrix dimensions (e.g., "16×16")
|
||||
|
||||
**Implementation:**
|
||||
- `canvas-renderer.js` - Client-side renderer that executes building blocks
|
||||
- Simplified versions of shapes, colors, and animations for browser rendering
|
||||
- Efficient pixel-by-pixel drawing with proper serpentine wiring support
|
||||
|
||||
### 2. Node Selector Dropdown
|
||||
|
||||
A dropdown has been added to the editor header for target selection:
|
||||
|
||||
- **Options**:
|
||||
- "Canvas Preview Only" (default) - Only renders to canvas
|
||||
- List of discovered nodes with IP addresses
|
||||
- **Auto-Discovery**: Automatically populates with available nodes
|
||||
- **Dynamic Updates**: Updates when nodes are discovered or lost
|
||||
- **Persistent Selection**: Maintains selection when nodes list refreshes
|
||||
|
||||
### 3. Dual-Mode Preview
|
||||
|
||||
The preview system now supports two modes:
|
||||
|
||||
**Canvas-Only Mode** (No node selected):
|
||||
- Renders animation to canvas preview only
|
||||
- No network traffic
|
||||
- Perfect for designing and testing
|
||||
- Uses client-side rendering engine
|
||||
|
||||
**Canvas + Node Mode** (Node selected):
|
||||
- Renders to both canvas AND transmits to selected node
|
||||
- Canvas preview for visual feedback
|
||||
- Node receives frames via server streaming
|
||||
- Synchronized rendering
|
||||
|
||||
### 4. Preview Controls
|
||||
|
||||
Enhanced preview control panel:
|
||||
|
||||
- **Start/Stop Button**: Toggles preview on/off
|
||||
- "▶️ Start Preview" when stopped
|
||||
- "⏸️ Stop Preview" when running
|
||||
- **Status Indicator**: Shows current mode
|
||||
- "Stopped" (gray) - Preview is off
|
||||
- "Canvas Preview" (green) - Rendering to canvas only
|
||||
- "Streaming to [IP]" (blue) - Rendering to canvas + node
|
||||
|
||||
### 5. Auto-Refresh on Changes
|
||||
|
||||
The preview automatically restarts when configuration changes:
|
||||
|
||||
- Adding a new layer
|
||||
- Deleting a layer
|
||||
- Loading a preset
|
||||
- Importing JSON
|
||||
- Animation states are reset for clean restart
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Canvas Renderer (`canvas-renderer.js`)
|
||||
|
||||
A browser-based implementation of the building blocks system:
|
||||
|
||||
**Features:**
|
||||
- Renders shapes: circle, rectangle, blob, point
|
||||
- Color generators: solid, gradient, rainbow
|
||||
- Animations: move, rotate, pulse, oscillate, fade
|
||||
- Pattern support: radial, spiral
|
||||
- Proper RGB color blending
|
||||
- FPS tracking and display
|
||||
|
||||
**Architecture:**
|
||||
```javascript
|
||||
class CanvasRenderer {
|
||||
- setSize(width, height) // Update matrix dimensions
|
||||
- renderConfiguration(config) // Render preset configuration
|
||||
- drawFrame(frame) // Draw frame to canvas
|
||||
- clear() // Clear canvas
|
||||
- reset() // Reset animation states
|
||||
}
|
||||
```
|
||||
|
||||
### Preview System Flow
|
||||
|
||||
```
|
||||
User clicks "Start Preview"
|
||||
↓
|
||||
1. Initialize canvas renderer
|
||||
2. Reset animation states
|
||||
3. Start render loop (20 FPS default)
|
||||
↓
|
||||
Every frame:
|
||||
- Execute building blocks
|
||||
- Render to canvas
|
||||
- Update FPS counter
|
||||
↓
|
||||
If node selected:
|
||||
- Also send config to server
|
||||
- Server streams to node
|
||||
```
|
||||
|
||||
### Node Discovery Integration
|
||||
|
||||
The editor subscribes to the main app's event bus:
|
||||
|
||||
```javascript
|
||||
eventBus.subscribe('nodeDiscovered', () => updateDropdown())
|
||||
eventBus.subscribe('nodeLost', () => updateDropdown())
|
||||
```
|
||||
|
||||
This ensures the node list stays synchronized with the Stream view.
|
||||
|
||||
## UI Layout Changes
|
||||
|
||||
### Before
|
||||
```
|
||||
[Editor Header]
|
||||
[Sidebar] [Layers] [Details]
|
||||
```
|
||||
|
||||
### After
|
||||
```
|
||||
[Editor Header with Preview Controls]
|
||||
[Sidebar] [Canvas Preview + Layers] [Details]
|
||||
```
|
||||
|
||||
The center panel now features the canvas preview prominently at the top, with the layer list below it.
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Example 1: Design Without Hardware
|
||||
|
||||
1. Create preset in editor
|
||||
2. Leave node selector at "Canvas Preview Only"
|
||||
3. Click "Start Preview"
|
||||
4. Watch animation in canvas
|
||||
5. Modify layers and see changes instantly
|
||||
6. No SPORE node required!
|
||||
|
||||
### Example 2: Test on Real Hardware
|
||||
|
||||
1. Create preset in editor
|
||||
2. Select target node from dropdown
|
||||
3. Click "Start Preview"
|
||||
4. Animation appears on both canvas and physical LED matrix
|
||||
5. Modify and see changes on both displays
|
||||
|
||||
### Example 3: Quick Iteration
|
||||
|
||||
1. Import an example preset
|
||||
2. Start canvas preview
|
||||
3. Modify parameters in layer details
|
||||
4. Changes automatically refresh
|
||||
5. When satisfied, select node and stream
|
||||
|
||||
## Performance
|
||||
|
||||
- **Canvas Rendering**: ~60 FPS capable, default 20 FPS
|
||||
- **Network Efficiency**: Only streams when node is selected
|
||||
- **CPU Usage**: Minimal, uses requestAnimationFrame equivalent (setInterval)
|
||||
- **Memory**: Efficient frame buffer management
|
||||

## Preset Editor
|
||||
|
||||
The **🎨 Editor** view allows you to create custom animations by combining reusable building blocks without writing code.
|
||||
|
||||
### Building Blocks
|
||||
|
||||
#### Shapes
|
||||
- **Circle**: Round shape with adjustable radius
|
||||
- **Rectangle**: Four-sided shape with width and height
|
||||
- **Triangle**: Three-sided shape
|
||||
- **Blob**: Soft circle with energy field falloff
|
||||
- **Point**: Single pixel
|
||||
- **Line**: Line between two points
|
||||
|
||||
#### Patterns
|
||||
- **Trail**: Fade effect on previous frames
|
||||
- **Radial**: Gradient radiating from center
|
||||
- **Spiral**: Rotating spiral arms
|
||||
|
||||
#### Colors
|
||||
- **Solid**: Single color
|
||||
- **Gradient**: Linear blend between two colors
|
||||
- **Palette**: Multi-stop gradient with custom colors
|
||||
- **Rainbow**: Color wheel effect
|
||||
|
||||
#### Animations
|
||||
- **Move**: Linear movement from point A to B
|
||||
- **Rotate**: Rotation around center
|
||||
- **Pulse**: Scale oscillation (breathing effect)
|
||||
- **Oscillate X/Y**: Sine wave movement on X or Y axis
|
||||
- **Fade**: Fade in or out
|
||||
|
||||
### Creating a Custom Preset
|
||||
|
||||
1. Navigate to the **🎨 Editor** view
|
||||
2. Enter a name and description
|
||||
3. Add layers (shapes or patterns):
|
||||
- Select type and configure properties
|
||||
- Set position, size, and color
|
||||
- Add optional animation
|
||||
- Click **➕ Add Layer**
|
||||
4. Edit layers with ✏️, reorder with ▲/▼, or delete with ✕
|
||||
5. Preview with **▶️ Preview** (requires a selected node from Stream view)
|
||||
6. **💾 Save** to browser localStorage or **📤 Export JSON** to file
|
||||
|
||||
### Example Presets
|
||||
|
||||
Import example JSON files from `presets/examples/` to learn:
|
||||
|
||||
- **Pulsing Circle**: Rainbow circle with pulse animation
|
||||
- **Bouncing Squares**: Multiple colored squares oscillating
|
||||
- **Spiral Rainbow**: Rotating spiral with rainbow gradient
|
||||
- **Moving Triangle**: Triangle with linear movement
|
||||
|
||||
Use **📥 Import JSON** to load examples and customize them.
|
||||
|
||||
### JSON Format
|
||||
|
||||
Presets are stored as JSON:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "My Preset",
|
||||
"description": "Custom animation",
|

|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Building Blocks Reference
|
||||
|
||||
### Shape Types
|
||||
- **circle**: Round shape with radius
|
||||
- **rectangle**: Four-sided shape with width and height
|
||||
- **triangle**: Three-sided shape with radius (determines size)
|
||||
- **blob**: Soft circle with energy field falloff
|
||||
- **point**: Single pixel
|
||||
- **line**: Line between two points
|
||||
|
||||
### Pattern Types
|
||||
- **trail**: Fade effect on previous frames
|
||||
- **radial**: Gradient radiating from center
|
||||
- **spiral**: Rotating spiral arms
|
||||
|
||||
### Color Types
|
||||
- **solid**: Single color
|
||||
- **gradient**: Linear blend between two colors
|
||||
- **palette**: Multi-stop gradient
|
||||
- **rainbow**: Color wheel effect
|
||||
- **radial**: Gradient from center outward
|
||||
|
||||
### Animation Types
|
||||
- **move**: Linear movement from point A to B
|
||||
- **rotate**: Rotation around center
|
||||
- **pulse**: Scale oscillation
|
||||
- **oscillateX/Y**: Sine wave movement on X or Y axis
|
||||
- **fade**: Fade in or out
|
||||
|
||||
## Tips
|
||||
|
||||
1. **Layer Order Matters**: Layers are rendered in order, so later layers appear on top
|
||||
2. **Combine Multiple Shapes**: Create complex effects by layering shapes with different animations
|
||||
3. **Use Phase Offsets**: For oscillating animations, use different phase values to desynchronize motion
|
||||
4. **Experiment with Colors**: Try different color combinations and gradients
|
||||
5. **Start Simple**: Begin with one layer and gradually add complexity
|
||||
6. **Test Early**: Preview frequently to see how your changes look in real-time
|
||||
|
||||
## Advanced Techniques
|
||||
|
||||
### Creating Trails
|
||||
Add a trail pattern layer with high decay factor combined with moving shapes:
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "pattern",
|
||||
"pattern": "trail",
|
||||
"params": {
|
||||
"decayFactor": 0.85
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Synchronized Motion
|
||||
Use the same frequency and phase for oscillating animations to create synchronized movement.
|
||||
|
||||
### Color Cycling
|
||||
Use the rainbow color type with pulse or rotate animations for dynamic color effects.
|
||||
|
||||
