Simple 2D graphics in C#

Indeed, it ins't straightforward at all. From what I read, I'd need to add a texture for every primitive I wanted. I'm looking for something that allows me to do something like:

Circle(new Vec(0,0), 5);
Polygon(new Vec(0,0), new Vec(2,2), new Vec(1,0));

Circle(new Vec(0,0), 5);
Polygon(new Vec(0,0), new Vec(2,2), new Vec(1,0));

(syntax is merely illustrative)

Rendering and updating a colormap

Unfortunately I have to go now. I'll try to integrate it at a later date (probably tomorrow). I'll let you know if I manage to do it (or if I have any more questions...). I can't thank you enough for your help!

So I would add this to MainWindow and invoke it from RenderFrame, am I right?

Alright, I'll make it readonly and deal with it. That can be a future me problem.

Then I'll try to get away with it being mutable, if I do get issues I'll change to immutable

Rendering and updating a colormap

Well, I don't think I'll really need it, so I'll take it out. As for making it readonly, would it still allow for something like some_color.r+=0.1f?

Rendering and updating a colormap

I've refactored it as such:

public struct Color
    {
        private float _r;
        private float _g;
        private float _b;

        public float r => _r;
        public float g => _g;
        public float b => _b;

        public float this[int index] {
            get => index switch {
                0 => _r,
                1 => _g,
                2 => _b,
                _ => throw new ArgumentOutOfRangeException(nameof(index))
            };
            set => {
                switch(value) {
                    case 0:
                        _r = value; break;
                    case 1:
                        _g = value; break;
                    case 2:
                        _b = value; break;
                    default:
                        throw new ArgumentOutOfRangeException(nameof(value));
                }           
            }
        }

        public Color(float r = 0, float g = 0, float b = 0) {
            this._r = r;
            this._g = g;
            this._b = b;
        }
    }

public struct Color
    {
        private float _r;
        private float _g;
        private float _b;

        public float r => _r;
        public float g => _g;
        public float b => _b;

        public float this[int index] {
            get => index switch {
                0 => _r,
                1 => _g,
                2 => _b,
                _ => throw new ArgumentOutOfRangeException(nameof(index))
            };
            set => {
                switch(value) {
                    case 0:
                        _r = value; break;
                    case 1:
                        _g = value; break;
                    case 2:
                        _b = value; break;
                    default:
                        throw new ArgumentOutOfRangeException(nameof(value));
                }           
            }
        }

        public Color(float r = 0, float g = 0, float b = 0) {
            this._r = r;
            this._g = g;
            this._b = b;
        }
    }

Is this fine? Or should I completely get rid of that indexer?

There's no harm in keeping the indexer, is there?

It's a colour - so I guess it is a single pixel.

I've of course looked at ColorScaleBitmapAdapter.Render, but I don't quite understand what's going on...

In this case, shouldn't it be

if (!Bitmap?.TryLock(new System.Windows.Duration(TimeSpan.FromMilliseconds(500))))

if (!Bitmap?.TryLock(new System.Windows.Duration(TimeSpan.FromMilliseconds(500))))

Using the null-forgiving member-access operator?

What is the !. operator in this line?
