public static void TexCoord3(float x, float y, float z)

Parameters

x

float

y

float

z

float

Remarks

In OpenGL this matches 
glMultiTexCoord
for all texture units or 
glTexCoord
when no multi-texturing is available. On other graphics APIs the same functionality is emulated.
The Z component is used only when:
1. You access a cubemap (which you access with a vector coordinate, hence x,y & z).
2. You do "projective texturing", where the X & Y coordinates are divided by Z to get the final coordinate. This would be mostly useful for water reflections and similar things.
This function can only be called between GL.Begin and GL.End functions.

Examples

using UnityEngine;public class Example : MonoBehaviour{    // Draws a Quad in the middle of the screen and    // Adds the material's Texture to it.    Material mat;    void OnPostRender()    {        if (!mat)        {            Debug.LogError("Please Assign a material on the inspector");            return;        }        GL.PushMatrix();        mat.SetPass(1);        GL.LoadOrtho();        GL.Begin(GL.QUADS);        GL.TexCoord3(0, 0, 0);        GL.Vertex3(0.25f, 0.25f, 0);        GL.TexCoord3(0, 1, 0);        GL.Vertex3(0.25f, 0.75f, 0);        GL.TexCoord3(1, 1, 0);        GL.Vertex3(0.75f, 0.75f, 0);        GL.TexCoord3(1, 0, 0);        GL.Vertex3(0.75f, 0.25f, 0);        GL.End();        GL.PopMatrix();    }}
