05 - Object Types
A Voxel - short for volumetric pixel - is basically a single colored cube.
A Matrix is a 3-dimensional grid of voxels. Matrices have a maximum size of 1024x512x1024. Try to keep your matrices as small as possible. Using large matrices over 128³ will decrease Qubicle's performance. Instead use several small matrices to build a bigger model.
A Model is always the root object of your file. It does not have a size or transform, it just exists as is. You can place as many objects in a model as you like.
Compounds enable you to organize your model. You can pack any amount of Matrices and other Compounds into a Compound and thus establish object hierarchies. Compounds will also speed up render performance and are useful for mesh export and modeling workarounds. If you are a Photoshop user then think of Compounds as Smart Objects. Compounds are distinguished from Matrices by a dashed bounding box.
