Mesh Box Reference Image<\/strong><\/p>\n

If you want to build a simple mesh box with scripts in Unity, this kind of image helped me to understand how it works..<\/p>\n

Also have a look of the ChunkRender example,
\nhow it builds the mesh by adding 4 vertices on each box face: ChunkRenderer<\/a><\/p>\n

Main image ^<\/strong>
\n– Vertice locations \/ coordinates are shown: Vector3(x<\/span><\/strong>,y<\/span><\/strong>,z<\/span><\/strong>)<\/p>\n

Part#2 :\u00a0Lets build a simple mesh<\/h3>\n

What are we doing:
\n– Initialize vertex points array (it is a list of points in 3D space)
\n– Initialize triangle index array (this list tells Unity how to connect the points, to build a polygon face = triangle)
\n– Add 1st point to the vertex array (0,0,0)
\n– Add 2nd point to the vertex array (0,1,0)
\n– Add 3rd point to the vertex array (1,1,0)
\n– Now we have 3 points in 3D space..(but we cannot see anything, since we just have points..)
\n– Assign triangle list [0,1,2] (“connect the points”, we start from (0,0,0), then go to (0,1,0), then (1,1,0))
\n– Last step: Assign the points and triangle list to our Unity mesh (and then we have a visible mesh)<\/p>\n

Image#2:<\/strong>
\n– In the image we have 3 points (vertices), marked with white “x”
\n– Dotted lines are showing how we connect the points (clockwise), to build a polygon face<\/span> <\/strong>(triangle<\/span>)<\/strong>

Our mesh box is actually build from bunch of triangles:
