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"

How can I copy a pixel and display it in the world at an extruded location


I wish to recreate a sci-fi holographic PC monitor (kind of like Minority Report).
My theory is like this. - I get the pixel colour. - If pixel colour matches then I get the world position. - I then draw a copy of the pixel X units along the pixel's normal direction. Projecting it into the world if you will.

Im not sure if I need two materials to do this with the original feeding pixel data into the second one or not. In fact I have no clue what I am doing. This isn't my area at all.

Is this possible and if so, how would I manage it.

Passing data from one material onto another is not possible (unless you are rendering first material into a render target and using this render target in the second material).

However none of the effects, seen in in Minority Report, would require to you perform such action, so you should re-think your approach.
