How do you make a voxel model explode?

Voxel models are made up of lots of blocks. So it seems logical that there are scenarios where you'd want them to come apart, shatter, EXPLODE!

I thought there would be something inbuilt. or discussion on how to do this, but I can't find anything. (well maybe a few things, but long before Craft existed).

So is there an easy way to blow up your model?!

    @RaggedTooth - since you are posting a variety of Voxel queries could you put them all in one thread, otherwise we’ll rapidly fill the page with Voxel queries.

    One of the mods can possibly move your existing queries into one.

  • Apologies, I didn't appreciate the forum etiquette.

    That's about it on voxels for now...

    The only way I know of to blow up a Voxel is to create the Voxel in various stages of explosion. Then you would have to display each one in sequence to simulate it blowing up. As far as I know, there’s no easy way to do it.

    @RaggedTooth Using the Voxel editor, I was able to create a simple Voxel and then I created 2 more in increasing stages of explosion. It was just a square made of 4 cubes and the other voxels were the 4 cubes moving farther away from the center. I used the Voxel active command to make each successive Voxel active and the previous one inactive. It was only 3 different voxels, but it showed that it could be done. To make a better explosion will take a lot more editing and voxels.

    @RaggedTooth - building an explosive Voxel could be quite expensive if you have a large number of fractions you need to make. The 36 vertices in a cube would increase to 288 in the 8 smaller cubes, if you broke each face into 4. A simpler, less expensive method ( if you built the model ) is to just use the triangles (faces) that constitute the model and add/multiply each vertex by the same factor so the faces effectively move away from each other. I think there is a very impressive example of a model explosion in the forum, I think from a sphere and , if I am not mistaken, made by @LoopSpace.

    @RaggedTooth I think we're talking about 2 different things. In the Voxel editor, a model is created using cubes. In the Froggy example, the cars are made up a bunch of different colored cubes. So to make the car explode, you would just take the different cubes that make up the car and draw another car where the cubes are farther apart. You would continue that moving the cubes farther apart in different images. You’re not exploding the cubes, just moving each of them apart.
