WebGL Features and Limits

When developing generative artwork for Layer, it's important to understand the WebGL capabilities available on target devices and any hardware-specific limitations.

Device Compatibility

Your artwork will run on devices with varying WebGL capabilities. Screenshots and final artwork are captured on devices with the Snapdragon 8 Gen 2 chipset, which represents the target platform for Layer artwork.

When optimizing your artwork, consider testing on or emulating devices with this chipset to ensure consistent visual output and performance. The WebGL capabilities of this device define the baseline for feature support.

Key Considerations

WebGL 2.0 support

Verify that your WebGL code is compatible with WebGL 2.0

Texture limits

Be aware of maximum texture sizes and count on target devices

Shader complexity

Keep shader code optimized for mobile GPUs

Memory constraints

Monitor VRAM usage, especially with high-resolution textures

Precision

Use appropriate precision qualifiers in shaders for mobile devices

Testing Recommendations

To ensure your artwork renders correctly on target devices:

Test on a Snapdragon 8 Gen 2 device or equivalent

Monitor GPU usage and thermal performance

Verify WebGL capabilities using gl.getParameter()

Test with various parameter combinations

Validate rendering consistency across multiple runs
