Asm/HLSL sample inside

Just a quad drawn with constant color. Demonstrates how to do write hlsl and asm shader into string ie. memory then compile/assemble the shader and draw the object. Notice, the only difference between the two is in Assemble() and Compile() calls everything else is the same. Data is passed into shaders thru constants, in hlsl using ''uniform'' keyword and '':'' constant syntax. Make a win32 project and paste in the text. Uses dx9 libs so make sure you have them listed in project settings ie. for debug

dxguid.lib, d3dx9d.lib, d3d9.lib) for release it''s d3dx9.lib and others stay the same. Have fun

I''m fine with c++/mfc/win32/dx9 for now, they haven''t limited me yet. Someone posted c# code hlsl example on this board, take a look around if you need it.

Duh, no doubt you''ve seen the c# code already as I checked it was posted in your thread topic. Sorry about beeing little slow today

Can''t you just take my c++ dx9 setup/hlsl calls and try to match them to c#/dx9 calls? Give it a try I don''t think the concepts are that radical between c++ and c#, or are they?

Ok, the string hlsl code is same as in c# and c++. What''s c# equivalent for D3DXCompileShader(), CreateVertexBuffer(), VertexBuffer->Lock/Unlock(), CreateVertexDeclaration(), SetVertexDeclaration(), SetStreamSource(), D3DXMatrixPerspectiveFovLH(), D3DXMatrixMultiply(), D3DXMatrixTranspose(), SetVertexShaderConstantF(), CreateVertexShader(), SetVertexShader(), DrawPrimitive(), Begin/End Scene(), Present().

Find c# objects that have these methods. Isn''t there a win32 eqivalent wizard in c# like win forms or something like that that would give you the windowing boilerplate?

Then just follow the order of calls, you don''t have to specifically since dx9 is state machine but it''ll be easier I think. That''s what I would do if I were you instead of waiting for someone to give me what I want. If I did that I would never have hlsl example working, I had to study CG manual and compare stuff to dx9 hlsl to figure stuff out. Don''t be lazy

Didn''t meant to offend you just give you some motivation and a start.

Ok, out of curiosity I looked at MS dx9 c# docs and I found everything that I would need to convert the above c++ example into c# code. Start with these two namespaces and their classes:

Microsoft.DirectX
- Structures
- Matrix, Vector3, etc.

Microsoft.DirectX.Direct3D
-ShaderLoader.CompileShader
-GraphicsStream
-Device
-VertexShader
-VertexDeclaration
-VertexElement

Read over their documentation then match their methods to my c++ code and proceed from there. There are also tutorials on how to setup windowing environment and direct3d so read them too. Each method spec shows examples how to use it. I know the docs are not the best but you really do have everything you need plus that bit of code someone posted in your original thread. Good luck!
