I am trying to display texture on mesh correctly but texture looks like crushed. I added references. I have texture on polygon I think there is UV problem.

}

Is that about IndexBuffer. If that is how can I correclty set it ? I use Draw instead should I use DrawIndexed but if I do that I see nothing is rendered.

I'm no SharpDX guru, but I do see one immediate issue with this provided code. You loop through presumably all the subsets of your mesh, creating a textureview for each subset. You than proceed to assign this textureview object to the same shader slot for each iteration.

And though it may be a managed language you're in, but than you proceed to throw your handle to that heap memory off the stack as soon as you exit that for loop. Does your object have multiple subsets? Each with it's own unique texture? You seem to be loading the same one for each iteration. And it seems the only mesh in question here is a cube.

Normally what you would want to do is load your texture once. Than when it comes time to draw, assign it to a shaderslot. (Though that's not set in stone, I just find that to be easy to track).

Another thing would be to include the UVs, and indices you're using. Those UVs could be buried in one of those Vector4's but i'm not seeing it.

There I added only part of the code it is not full normally I will add it. Most probably problem is UV but I do not know how to add UV. After adding how can I get it work ? There is something called IndexBuffer is that about UV ?

Naw, index buffers hold indices that tell the IA stage how to piece together your vertice positions. For large meshes with potentially thousands of redundant vertices, the memory savings add up.

So looking over your UVs, you only have four. Normally you're gonna want a UV for each vertice position (Think about it from the VertexShader point of view, and I think you'll understand why).

So by judging on the front face of your cube, your front face UVs should read like this:


new Vector2(0f,1f),
new Vector2(0f,0f),
new Vector2(1f,0f),
new Vector2(0f,1f),
new Vector2(1f,0f),
new Vector2(1f,1f),

If this doesn't work for whatever reason, you get the idea, play around with the values until it does.

Now, these WILL work for the other faces, BUT they will "rotated" (Not the correct terminology) at a different angle. So I'll leave this reference image for you to figure out the other faces UV positions

Thank you I fixed it. I checked my TEXCOORD call and I saw something like :


 new InputElement("TEXCOORD", 0, Format.R32G32_Float, InputElement.AppendAligned, 0)

I changed InputElement.AppendAligned to 16 and it was fixed for my cube. I did not get what does it mean InputElement.AppendAligned. However, problem is fixed.
