   How to find out a point properties according to a quad.
  I have big quad which has positions information, but no property values.I have a small quad which has position information and properties.I am trying to calculate big quad's properties, I tried to use barycentric coordinate to calculate but the result was not correct and it seems that I need to calculate according all the small quad's position information.Anyone can help?   
  What do you mean by "properties"? What kind of properties?Also, what is the relationship between the small quad and the big one?   ;Quote:Original post by Gage64What do you mean by "properties"? What kind of properties?Also, what is the relationship between the small quad and the big one?Thank you for reply.Big quad and small quad have position using same coordinate system, they are 2D quad. Property could be diffuse color or something else which could be interpolated for each pixels inside the quad.
