Whenever I appear to create a rotation matrix or attempt to zoom, the meshes that I draw to the display screen get stretched and distorted.

I’ve tried to make a easy rotation matrix like this:

Matrix remodel = Matrix.CreateRotationZ(MathHelper.ToRadians(ang))

And then I do that once I make the vertices:

verts[i].Position = Vector3.Transform(verts[i].Position, remodel);

And it does rotate it, nevertheless it additionally will get stretched on the identical time.

Similarly, I made a easy Camera class:

utilizing Microsoft.Xna.Framework;
utilizing Microsoft.Xna.Framework.Graphics;
utilizing Microsoft.Xna.Framework.Input;
utilizing System;
utilizing System.Collections.Generic;

namespace _04_texturedquad
{
    public class Camera
    {
        public Vector2 place {get; personal set;}

        public Matrix ortho;

        float zoom;

        public float rotation;

        Viewport viewport;

        public Camera(Viewport v)
        {
            this.viewport = v;

            ortho = Matrix.CreateOrthographicOffCenter(
            0, 
            viewport.Width, 
            0, 
            viewport.Height, 
            0, 1);
        }

        public void Move(Vector2 vec)
        {
            this.place += vec;
            Update();
        }

        public void Zoom(float quantity)
        {
            zoom += quantity;
            Update();
        }

        public void SetPosition(Vector2 vec)
        {
            this.place = vec;
        }

        public void Update()
        {
            ortho = Matrix.CreateOrthographicOffCenter(
            0               + place.X - zoom, 
            viewport.Width  + place.X + zoom, 
            0               + place.Y - zoom, 
            viewport.Height + place.Y + zoom, 
            0, 1);
        }
    }
}

And shifting round works, however once I zoom, it does zoom, nevertheless it additionally will get stretched vertically once I accomplish that.

Here’s what I’m doing when I’m sending the buffers to the GPU:

public void Draw()
    {

        RasterizerState rs = new RasterizerState();
        recreation.GraphicsSystem.RasterizerState = rs;

        impact.Projection = c.ortho;

        foreach (EffectPass cross in impact.CurrentTechnique.Passes)
        {   
            cross.Apply();
            recreation.GraphicsSystem.DrawUserIndexedPrimitives(PrimitiveType.TriangleList, _vertices, 0, _vertices.Length, _indices, 0, _indices.Length / 3, VertexPositionShade.VertexDeclaration);
        }
    }

I’ve additionally tried setting impact.View = Matrix.Identity, however that hasn’t labored both.

Why does every part get distorted once I zoom/rotate? I do not assume this can be a drawback with how I’m making the meshes, as a result of they appear superb in any other case.
