opentk

问题 i'm trying to use an index buffer but have no idea how i really am stuck in a waall as to what i'm supposed to even try so. none of the tutorials really show anything similar to my code which is mostly why i'm having problems. i might have to rewrite cube vertex array creator. (on a different note maybe i shouldn't have just shoved opengl into some ready code)right now i've only enabled the top face as to see what's going on. /// <summary> /// Draws the specified Cube Onsccreen. /// </summary

问题 I just installed MonoGame and OpenTK 1.0 and in Visual Studio 2012 I made a new project of type 'Windows OpenGL Game`...but when I run the project I get the following error: The type initializer for 'OpenTK.Graphics.GraphicsMode' threw an exception. The error is right on this line (the consturctor, on the base()) public Game1() : base() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } My laptop has intel oboard graphics 3000 and I think it supports OpenGL..

问题 I'm trying to print the bitmap data to the screen with opentk. GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, data.Width, data.Height, 0, OpenTK.Graphics.OpenGL.PixelFormat.Bgra, PixelType.UnsignedByte, data.Scan0); I get an error on the part. My guess is I'm writing the formats wrong. With Format8bppIndexed, I can view properly in picturebox. My incoming image is black and white. incoming data; BitmapSingleImage = new Bitmap(rsSplitWidth, rsSplitHeight, rsSplitWidth,

问题 I'm currently trying to get into GLSL using the OpenGL superbible and http://www.learnopengl.com/. My desired environment is OpenTK. I tried to convert the "Hello Triangle" entry level tutorial from learnopengl.com into OpenTK, it is meant to draw a triangle using very simple shaders, without using any perspective/world/model transformations. My result is just the colorbuffer, but else an empty window and i simply do not understand where i have made a mistake so any help in finding and more

问题 I am drawing multiple images over earh map, I am using perspective correct texturing link on each image. I want to store rendered image in to file (sorce file is 1280x760, the rendered images is around 160x90 in most cases rotated). Currently I am doing this with GL.ReadPixels int width = 1920; int height = 1080; using (Bitmap bitmap = new Bitmap(width, height)) { System.Drawing.Imaging.BitmapData bits = bitmap.LockBits(new Rectangle(0, 0, width, height), System.Drawing.Imaging.ImageLockMode
