Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Procederal Buildings?

I'm guessing the best place for this is c++ programming but I apologize if not. I'm curious if anyone has done procedural 3D buildings over time based on known models (as in an NPC carries a stone and drops it in a location, animation of mortar being applied, then the stone becomes a part of the mesh.)

If not, any thoughts on how to accomplish this? Thus far I'm thinking it might take separate stages or layers to do things like build a pyramid (i.e. NPCs lay down a layer of stone and mortar sliced from a base model at the stone thickness, then when the layer is complete it becomes a single mesh with a material over it and the next layer starts - ultimately for details like angled stones or stairs they would go in as a separate model at the same location as the first one before following a similar process.) An example of the layering process I have in mind would be like the image below, where layers would be drawn in the order red-green-blue one at a time with each one starting at the bottom and ending at the top to allow for different types of stone/mortar to fill each layer.
