C to Pascal

[vhelp]

i was googling around for any info i could find on "true" sepia equations that i hoping to resuse in one of my filters when i came across this c/c++ code snipplet. i think they refer to this as short-curcuiting though the page use the term, 'vectorized' as an alternate method than the longer 7 or so coded lines.

float3 FindMedian(float3 RGB, float3 RGB2, float3 RGB3)
{ 
    return (RGB < RGB2) ? ((RGB2 < RGB3) ? RGB2 : max(RGB,RGB3) ) : ((RGB < RGB3) ? RGB : max(RGB2,RGB3));
} 

note, the code does not relate to sepia but was on the same page, found here:
http://wiki.gamedev.net/index.php/D3DBook:Useful_Effect_Snippets

so my question, is there something similar in pascal (delphi) or is this unique to c/c++ ?

i'm using version 6, i suppose borland made changes in later versions, but i don't know since i don't use it, yet, thank you.

edit: i don't know what the garbage in the findMedian() filter, so i appologies. even the wepage (see link) has it, so i'm not sure what's suppose to go in there.

float3/4 data types are vector data types (as opposed to scalar types) and are usually used within the context of an open cl or cuda program as a way of using the gpu's simd array. considering you found this code snippet in a site that deals with d3d programming, it looks like they are showing you how to rearrange code meant to run on a cpu so that it runs on a gpu using the dx9 api, specifically d3d surfaces.

i believe that it is possible to use the dx9 api from within pascal/delphi, i'm failry certain some libraries have been ported to allow this functionality, but it's going to be a major pain in the ass.

you may just have to stick with pure cpu executed code if you wish to use pascal.
