Hi,

In SM4 or above, we have


Texture Object (DirectX HLSL). Here is the syntax for creating all texture objects (except multisampled objects).
Object1 [<Type>] Name;

Suppose I want to write a function that takes a Texture2D parameter. What should the syntax look like?

Depends on the surface format, Texture2D could have many declarations like

Texture2D<int>

Texture2D<int2>

Texture2D<float>

Texture2D<float4> etc.

It is unrealistic to write functions for all possible combinations, say


MyFunc(Texture2D<int> tex2d)
MyFunc(Texture2D<int2> tex2d)
MyFunc(Texture2D<float> tex2d)
MyFunc(Texture2D<float4> tex2d)

ideally, I want something like
template<type>

MyFunc(Texture2D<type> tex2d){}

but it gives me errror message like
error X3000: syntax error: unexpected token 'template'

any idea? thank you very much for your help.

Will you ever need to call your function on ALL possible texture types? I don't believe. So every-time a need for a new type arises, add a new overload. That's about the best you can do, if you don't want a MACRO-hell. You'll have to hard-code them all.

hi pcmaster,

you raised a good point. and, I am writing a library for others to use. thus, I guess i have to handle all possiblities.

thank you,
