I don’t quite know the term of this technique, but I’ll try to make it as understandable as possible.
In some games (esp strategy games). Lets say you set the target for your ion cannon or place a building on the terrain. The targetting retina(an alpha texture) will appear on the terrain following your mouse cursor, i noticed some games (like WoW) the ‘targetting’ texture wraps on the terrain texture itself (if the terrain polygon is bumpy the targetting texture will skew accordingly).
What is this method called? And how is this achieved?
Let me know for more clarifications if its still confusing.
