How does a triangle mesh store its triangles?
While a natural representation would be to have a Triangle shape implementation where each triangle stored the positions of its three vertices, a more memory-efficient representation is to separately store entire triangle meshes with an array of vertex positions where each individual triangle just stores three offsets …
How many triangles should a game character have?
In general terms, if you are not really sure, anything between 10.000 and 30.000 triangles should be safe, for PC.
What is a mesh in 3D Modelling?
3D models are modelled out of polygons that are connected at their edges and vertices to define the shape of an object in 3D – such a collection of polygons is called a mesh, and a 3D model is a collection of one or more 3D meshes.
What do you need to make a mesh in Unity?
To create a larger shape many small triangles are tiled together. To generate any kind of mesh we need 3 different components: vertices, triangles, and a material (we already set the material we will be using above, so only 2 things left to do).
How to create a mesh in Visual Studio?
Double-click the file to open it in Visual Studio (or whatever environment you have set for editing your scripts. You can set this under Preferences, External Tools). The heart of any terrain is the Mesh object.
How are the vertices and vertices of a triangle related?
In a typical triangle mesh that is supposed to represent the boundary surface of some physical object, there will be a direct relationship between the numbers of vertices and triangles.
How are the vertices of a triangle described in Unity?
A triangle has vertices to position it in space. Unity expects vertices, or any point really to be described in terms of 3D euclidian coordinates: X, Y, and Z. To simplify we are going to deal with 2D space for now, so X and Y only. For our triangle this would mean (going from the bottom left in clockwise rotation):
