For anyone who wants it, here's my cube, complete with UVs: (Using clockwise winding) If you're interested in using backface culling, these would be the settings: GL.Enable(EnableCap.CullFace); GL.CullFace(CullFaceMode.Back); GL.FrontFace(FrontFaceDirection.Cw); // - Cube code float size = 10F; // FRONT GL.Normal3(0, 0, 1); GL.TexCoord2(0, 0); GL.Vertex3(-size, +size, +size); GL.TexCoord2(1, 0); GL.Vertex3(+size, +size, +size); GL.TexCoord2(1, 1); GL.Vertex3(+size, -size, +size); GL.TexCoord2(0, 1); GL.Vertex3(-size, -size, +size); // LEFT GL.Normal3(-1, 0, 0); GL.TexCoord2(0, 0); GL.Vertex3(-size, +size, -size); GL.TexCoord2(1, 0); GL.Vertex3(-size, +size, +size); GL.TexCoord2(1, 1); GL.Vertex3(-size, -size, +size); GL.TexCoord2(0, 1); GL.Vertex3(-size, -size, -size); // BACK GL.Normal3(0, 0, -1); GL.TexCoord2(0, 0); GL.Vertex3(+size, +size, -size); GL.TexCoord2(1, 0); GL.Vertex3(-size, +size, -size); GL.TexCoord2(1, 1); GL.Vertex3(-size, -size, -size); GL.TexCoord2(0, 1); GL.Vertex3(+size, -size, -size); // RIGHT GL.Normal3(1, 0, 0); GL.TexCoord2(0, 0); GL.Vertex3(+size, +size, +size); GL.TexCoord2(1, 0); GL.Vertex3(+size, +size, -size); GL.TexCoord2(1, 1); GL.Vertex3(+size, -size, -size); GL.TexCoord2(0, 1); GL.Vertex3(+size, -size, +size); // TOP GL.Normal3(0, 1, 0); GL.TexCoord2(0, 0); GL.Vertex3(-size, +size, -size); GL.TexCoord2(1, 0); GL.Vertex3(+size, +size, -size); GL.TexCoord2(1, 1); GL.Vertex3(+size, +size, +size); GL.TexCoord2(0, 1); GL.Vertex3(-size, +size, +size); // BOTTOM GL.Normal3(0, -1, 0); GL.TexCoord2(0, 0); GL.Vertex3(-size, -size, +size); GL.TexCoord2(1, 0); GL.Vertex3(+size, -size, +size); GL.TexCoord2(1, 1); GL.Vertex3(+size, -size, -size); GL.TexCoord2(0, 1); GL.Vertex3(-size, -size, -size);

HAHAHA I CAN NOW PUT NACHO TEXTURES ON THE GROUND YEAH! thanks for this tutorial :)

[@aymericgoupil2138]

This is some fine tutorial, the explanations are clear. Thank you very much !

[@artistmeme8103]

If I save the image within the project, can I set the directory starting from the Project file, and not the drive?

[@thiagarajanv1143]

Thanks, nice explanation. Can you explain about zoom functions and Rotate function using mouse.. please.

[@nolanvannoyofficial]

can you link the code mine shows up as black and iv looked threw all your videos like 10 times

[@chris_burrows]

Nice man keep em coming!!

[@seamusforever7081]

What if i want multiple textures?, how'd i specify what texture i'm setting the vertex coordinates to?

[@seamusforever7081]

Btw, nice tutorial.

[@andreibalasa745]

Need help please ! Gl.teximage2d(...) raises accesviolationexception

[@_jeck_]

Doesn't work for me. I can get polygons to load just fine, but not textures.

I'm trying to recreate the torch by looking at the json { "ambientocclusion": false, "textures": { "particle": "#torch" }, "elements": [ { "from": [ 7, 0, 7 ], "to": [ 9, 10, 9 ], "shade": false, "faces": { "down": { "uv": [ 7, 13, 9, 15 ], "texture": "#torch" }, "up": { "uv": [ 7, 6, 9, 8 ], "texture": "#torch" } } }, { "from": [ 7, 0, 0 ], "to": [ 9, 16, 16 ], "shade": false, "faces": { "west": { "uv": [ 0, 0, 16, 16 ], "texture": "#torch" }, "east": { "uv": [ 0, 0, 16, 16 ], "texture": "#torch" } } }, { "from": [ 0, 0, 7 ], "to": [ 16, 16, 9 ], "shade": false, "faces": { "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#torch" }, "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#torch" } } } ] }

Great stuff, but if I drag the game window onto a second monitor it stops rendering. How can we fix this ?

[@samma-pixelstudio]

the second monitor is attached to you'r main GPU because if you are using another gpu and this gpu does not support openGl does not work the app

[@ricardomunhoz6706]

Very good , tks

[@eabarroso]

Dude, how are you? I don't know if you can help me, but I'll try anyway. I have a png file, like the minecraft torch, however, I can't render it correctly, that is, get all the faces of the cube correctly aligned, can you help me?

[@rafaeltab]

using System.Drawing.Imaging;

Noice video!
