Methods
AddQuad(int, int, int, int, bool)
Adds a quad to the geometry (by adding two triangles) List the four vertices in clockwise order as seen from the outside The diagonal will be created between the first and third vertex The indices must exist in the geometry, i.e. they first need to be added using AddVertex()
Declaration
public void AddQuad(int v0, int v1, int v2, int v3, bool flipNormals = false)Parameters
| Type | Name | Description |
|---|---|---|
| int | v0 | Index of vertex 1 |
| int | v1 | Index of vertex 2 |
| int | v2 | Index of vertex 3 |
| int | v3 | Index of vertex 4 |
| bool | flipNormals | If set to true, the quad will face the other way |
AddTriangle(int, int, int, bool)
Adds a triangle to the geometry List the three vertices in clockwise order as seen from the outside The indices must exist in the geometry, i.e. they first need to be added using AddVertex()
