cscの作法 その579

概要

cscの作法、調べてみた。
OpenRCF v2.8、見つけたので、windows11で、MSbuildしてみた。
練習問題やってみた。

プリミティブを作れ。

サンプルコード

using System;
using System.Windows;
using OpenRCF;
using Vector = OpenRCF.Vector;
using OpenTK;
using OpenTK.Graphics;
using OpenTK.Graphics.OpenGL;

    class Traiangle {
		private float radius = 0.2f;
		public Vector Position = new Vector(3);
		public RotationMatrix Rotate = new RotationMatrix();
		public Color Color = new Color();
		public float SizeX = 0.5f,
			SizeY = 0.5f;
		public float Radius {
			get {
				return radius;
			}
			set {
				radius = value;
			}
		}
		public Traiangle(float sizeX = 0.5f, float sizeY = 0.5f) {
			SizeX = sizeX;
			SizeY = sizeY;
			Radius = sizeX;
		}
		private float[][] Vertex = new float[3][];
		private static class BaseVertex {
			public static float[][] Vertex = new float[3][];
			static BaseVertex() {
				Vertex[0] = new float[3] { -0.5f,  0.3f, 0 };
				Vertex[1] = new float[3] { -0.5f, -0.5f, 0 };
				Vertex[2] = new float[3] {  0.3f, -0.5f, 0 };
			}
		}
		public void Draw() {
			VertexUpdate();
			Color.EnableBodyColor();
			DrawVertex(PrimitiveType.Polygon);
		}
		private void DrawVertex(PrimitiveType primitiveType) {
			GL.Begin(primitiveType);
			GL.Normal3(Rotate[0, 2], Rotate[1, 2], Rotate[2, 2]);
			for (int i = 0; i < Vertex.GetLength(0); i++)
			{
				GL.Vertex3(Vertex[i]);
			}
			GL.End();
		}
		private void VertexUpdate() {
			float[] vector = new float[3];
			for (int i = 0; i < Vertex.GetLength(0); i++)
			{
				vector[0] = SizeX * BaseVertex.Vertex[i][0];
				vector[1] = SizeY * BaseVertex.Vertex[i][1];
				vector[2] = 0;
				Vertex[i] = Position.Plus(Rotate * vector);
			}
		}
	}

以上。
