Question 1

How does Zdog compare to Three.js for web 3D?

Accepted Answer

Zdog is lighter and simpler, ideal for basic pseudo-3D effects and quick prototyping, but Three.js is better for complex 3D graphics with WebGL, textures, and lighting. Zdog uses 2D APIs, while Three.js leverages GPU acceleration for more realistic scenes.

Question 2

How to add text in a Zdog scene?

Accepted Answer

Zdog doesn't have built-in text support, but you can use the Zfont plugin mentioned in the README or create text with SVG paths. This requires extra setup compared to native text rendering in other engines.

Question 3

Can I use Zdog with React or Vue?

Accepted Answer

Yes, but integration isn't seamless; there's a community vue-zdog wrapper for Vue, but for React, you'd need to manually manage the canvas or SVG element and handle lifecycle events, which adds complexity.

Question 4

What are the performance limits of Zdog with many shapes?

Accepted Answer

Since Zdog renders with 2D APIs, performance can degrade with hundreds of shapes, especially on mobile devices, due to CPU-based drawing. It's best optimized for simple scenes with a moderate number of elements.

Question 5

How to animate multiple shapes independently in Zdog?

Accepted Answer

You can animate shapes by updating their properties, like translation or rotation, in the animation loop as shown in the demo. Each shape instance can be controlled separately, but complex animations may require custom logic.

Question 6

Is Zdog suitable for 3D data visualizations?

Accepted Answer

Yes, for simple pseudo-3D charts or diagrams with interactive rotations, Zdog works well due to its lightweight nature. However, for large datasets or complex visualizations, dedicated libraries like D3.js might be more efficient.
