I use DX9 development game, a 2 d pixels with Sprite - & gt; The Draw texturing, if cooperate ps2.0, Draw a picture is normal, but if change to 3.0, painted a piece of pure color, after try a variety of experiments, the accurate conclusion: incoming texture coordinates always (0.0 f to 0.0 f), the following is a code

 
Sampler2D s2D; 

Float4 Common (float2 Coord: TEXCOORD, float4 Color: Color) : Color 
{
Return tex2D (s2D, Coord) * Color; 
} 

The above code, when choosing compiler for ps2.0 Coord is normal, but if the compiled into 3.0, Coord always is zero, a great god knows what reason be?

CodePudding user response:

There is no set the texture coordinates in creating model,

DX9 above win10 all debugging
