How can i change the center point of the mesh? (SOLVED)

[Emre]

Hi,
In the “custom geometry tutorial” or the “projected grid” project I’m working on, the center point of the object is always the corner of the object.

How can I center it? There is an option called “Center Geometry” in the model import window. Is there a way to do this for a realtime generated mesh/model with code?

Thanks in advance.

Okay, in the custom geometry tutorial the problem is solved with vertex shifting. I solved the problem by making the vertex positions -50, 50 instead of 0, 100. But I don’t know how to do this in projected grid.

Can someone tell me how to shift vertexes in these codes?

public Mesh CreateQuad(int numVertsX, int numVertsY)
{
	Vector3[] vertices = new Vector3[numVertsX * numVertsY];
	Vector2[] texcoords = new Vector2[numVertsX * numVertsY];
	int[] indices = new int[numVertsX * numVertsY * 6];

	for (int x = 0; x < numVertsX; x++)
	{
		for (int y = 0; y < numVertsY; y++)
		{
			Vector2 uv = new Vector3(x / (numVertsX - 1.0f), y / (numVertsY - 1.0f));

			texcoords[x + y * numVertsX] = uv;
			vertices[x + y * numVertsX] = new Vector3(uv.x, uv.y, 0.0f);
		}
	}

	int num = 0;
	for (int x = 0; x < numVertsX - 1; x++)
	{
		for (int y = 0; y < numVertsY - 1; y++)
		{
			indices[num++] = x + y * numVertsX;
			indices[num++] = x + (y + 1) * numVertsX;
			indices[num++] = (x + 1) + y * numVertsX;
			
			indices[num++] = x + (y + 1) * numVertsX;
			indices[num++] = (x + 1) + (y + 1) * numVertsX;
			indices[num++] = (x + 1) + y * numVertsX;
		}
	}
	//mesh.UpdateMesh here 
}

EDIT: Here is the solution:

vertices[x + y * numVertsX].X -= 0.5f;
vertices[x + y * numVertsX].Y -= 0.5f;
