This function adds a new triangle to a surface.

Syntax

• int AddVertex(float x, float y, float z, float nx=0.0, float ny=0.0, float nz=0.0, float u0=0.0, float v0=0.0, float u1=0.0, float v1=0.0, float r=1.0, float g=1.0, float b=1.0, float a=1.0)

Parameters

• x: the X component of the vertex position.
• y: the Y component of the vertex position.
• z: the Z component of the vertex position.
• nx: the X component of the vertex position.
• ny: the X component of the vertex position.
• nz: the X component of the vertex position.
• u0: the first vertex indice to add.
• v0: the second vertex indice to add.
• u1: the third vertex indice to add.
• v1: the first vertex indice to add.
• r: the red component of the vertex color.
• g: the green component of the vertex color.
• b: the blue component of the vertex color.
• a: the alpha component of the vertex color.
• position: the vertex position.
• normal: the vertex normal.
• texcoords0: the first vertex texcoord set.
• texcoords1: the second vertex texcoord set.
• color: the vertex color.

Returns

Returns the index of the new vertex, equal to the number of vertices minus one.
