Apply a texture from a HBITMAP to a wall in the sample DirectX11 room
Hi,
is it possible using the code from the sample OculusTinyRoom(DX11) to apply a texture to a solid from a HBITMAP?
The sample code is
TriangleSet walls;
walls.AddSolidColorBox(-10.1f, 0.0f, -20.0f, -10.0f, 4.0f, 20.0f, 0xff808080); // Left Wall
Add(new Model(&walls, Vector3f(0, 0, 0), new Material(new Texture(false, Sizei(256, 256), Texture::AUTO_WALL))));
Let's say that I want apply a HBITMAP texture on this wall, how can I do it in a simple way?
Thanks

- There is no such thing as a HBITMAP texture, why not simply make a texture out of it?
- What? I want to know how to make a texture using a HBITMAP but mostly I want to know how to integrate it with the already existing code of the sample. can you help me?
- I found a sample for OpenGL

but i guess you can also use the buffer for something like thisID3D11Texture2D *tex;D3D11_TEXTURE2D_DESC tdesc;D3D11_SUBRESOURCE_DATA tbsd;tbsd.pSysMem = (void *)bits;tbsd.SysMemPitch = w * 4;tbsd.SysMemSlicePitch = w*h * 4; // Not needed since this is a 2d texturetdesc.Width = w;tdesc.Height = h;tdesc.MipLevels = 1;tdesc.ArraySize = 1;tdesc.SampleDesc.Count = 1;tdesc.SampleDesc.Quality = 0;tdesc.Usage = D3D11_USAGE_DEFAULT;tdesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM_SRGB;tdesc.BindFlags = D3D11_BIND_SHADER_RESOURCE;tdesc.CPUAccessFlags = 0;tdesc.MiscFlags = 0;if (FAILED(myDevice->CreateTexture2D(&tdesc, &tbsd, &tex))) {delete[] buf;return(0);} - But I see no DX11 in your sample, seems to be wrapped in classes somehow
- Hi,
Sorry but I don't see any HBITMAP in your code in the DirectX part, this just looks like the sample code from Oculus Tiny Room Directx11. How do I create a texture from a HBITMAP? - you need to access the bits of the bitmap and squirt them into a directx texture as thewhiteambit explained above.
Getting the bits from an HBITMAP is a pain as it's a legacy GDI function. You'd be better off avoiding all that stuff.
If you really must do it that way, this explains how to access the bitmap data from the handle.
