LÖVE

Hi, does somebody understand what the layers parameter for function newVolumeImage is? And if this can be constructed from a single image exported as slices from MagicaVoxel?

Löve can only load from PNG or JPG, and both of these are 2D image formats. In order to have the pixels defined for all 3 dimensions, you need one 2D image per every Z coordinate. These images are the layers, and you pass them as a table of images. The docs are not clear on the mapping, but most likely Z=0 corresponds to the image at index 1 and so on (so, Z = index - 1).

Not only. LÖVE supports many formats. See Image_Formats and PixelFormat.

Oh right, thanks for the correction. I don't know where I got that from. The point still stands, though, that none of the file types is 3D and the layers are the different 2D images used for different Z coordinates.

Hmm, correct me if i am understanding this wrong. But the volume image is a voxel like 3D texture accelerated by GPU?

A VolumeImage is a 3D texture. All that means is that the texture not only has width and height, but also depth - basically a stack of 2D images. It doesn't by itself provide 3D/voxel rendering, it's merely a data structure.
