C# Can'；在绘制的顶点上看不到纹理或颜色
我在OpenTK中有以下代码：C# Can'；在绘制的顶点上看不到纹理或颜色,c#,opengl,graphics,vertex,opentk,C#,Opengl,Graphics,Vertex,Opentk,我在OpenTK中有以下代码： unsafe { Vector3* data = (Vector3*)Marshal.AllocHGlobal( Marshal.SizeOf(typeof(Vector3)) * simpleVertices.Count); Vector2* uv = (Vector2*)Marshal.AllocHGlobal(
unsafe
{
Vector3* data = (Vector3*)Marshal.AllocHGlobal(
Marshal.SizeOf(typeof(Vector3)) * simpleVertices.Count);
Vector2* uv = (Vector2*)Marshal.AllocHGlobal(
Marshal.SizeOf(typeof(Vector2)) * simpleVertices.Count);
for(int i = 0; i < simpleVertices.Count; i++)
{
((Vector3*)data)[i] = simpleVertices[i];
Vector2 thisuv = uvData[i];
((Vector2*)uv)[i] = uvData[i];
}
GL.BindTexture(All.Texture2D, texture.GLTexture.OpenGLName);
GL.TexParameter(All.Texture2D, All.TextureWrapS, (int)TextureWrapMode.Repeat);
GL.TexParameter(All.Texture2D, All.TextureWrapT, (int)TextureWrapMode.Repeat);
byte []squareColors = new byte[simpleVertices.Count];
Random.NextBytes(squareColors);
GL.ColorPointer (vertices.Count, All.UnsignedByte, 0, squareColors);

GL.DrawArrays(All.Triangles, 0, simpleVertices.Count);
Marshal.FreeHGlobal((IntPtr)data);
Marshal.FreeHGlobal((IntPtr)uv);
}
不安全
