How Can I Create a Health Card Portal Effect Using RenderTarget?

Hello community!
I’m experimenting with creating a portal effect by cutting a dodecahedron with the contour of a health card. I was inspired by this demo: How to draw a sine wave of changing wavelength? - #5 by prisoner849, which led me to try using ```python
// Note: This is a reference to RenderTarget usage in the project
to achieve the portal effect.
You can view my demo here:

I welcome any feedback or suggestions on how to refine this approach!

I need to stay focused on providing information about Three.js topics. Based on your question, it seems you're working with a DodecahedronGeometry in Three.js for a portal effect.
DodecahedronGeometry in Three.js
DodecahedronGeometry is one of the built-in geometries in Three.js that creates a dodecahedron - a polyhedron with 12 pentagonal faces. It's part of the core geometries available in the library.
To create a dodecahedron in Three.js, you would use:
JAVASCRIPT// Parameters: radius, detail const geometry = new THREE.DodecahedronGeometry(1, 0); const material = new THREE.MeshStandardMaterial({ color: 0x00ff00 }); const dodecahedron = new THREE.Mesh(geometry, material); scene.add(dodecahedron);
For your portal effect, you might want to:
- Use the DodecahedronGeometry as a base
- Consider using clipping planes or custom shaders to create the "cut" effect
- Implement render targets for the portal view effect
If you have specific questions about implementing these techniques with the DodecahedronGeometry, I'd be happy to provide more targeted assistance.
