depthtoworld cg shader kinect jit.openni

hi all,
I work ona depth to world coordinates (from kinect and jit.openni object) cg shader, to do a very efficient real-time mapping.
I have an issue with cg shader, max tells me
"(33) : error C3004: function "texRECT" not supported in this profile
"
I'm asking for help :)

here's my jxs, vp and fp files. thx
you

Ad

jxs :

map depth kinect to world coordinate.

vp:

uniform samplerRECT depthMap : TEXUNIT0;
uniform float4x4 mvp : state.matrix.mvp;

float rawDepthToMeters(float depthValue) {
if (depthValue < 1f) {
return (float)(1.0 / (depthValue * -0.0030711016 * 2047 + 3.3309495161));
}
return 0.0f;
}

float3 depthToWorld(float x, float y, float depthValue) {

float fx_d = 1.0 / 5.9421434211923247e+02;
float fy_d = 1.0 / 5.9104053696870778e+02;
float cx_d = 3.3930780975300314e+02;
float cy_d = 2.4273913761751615e+02;

float3 result = float3(0,0,0);
float depth = rawDepthToMeters(depthValue);
result.x = (x - cx_d) * depth * fx_d;
result.y = (y - cy_d) * depth * fy_d;
result.z = depth * 200;
return result;
}

void main(
in float4 iVertex : POSITION,
in float2 iTexCoord : TEXCOORD0,
out float4 oVertex : POSITION,
out float2 oTexCoord : TEXCOORD0
){
float4 vertex = iVertex;
float depth = texRECT(depthMap, iTexCoord).r;
vertex.xyz += depthToWorld(iVertex.x,iVertex.y,depth);
oVertex = mul(mvp,vertex);

oTexCoord = iTexCoord;
}

fp:

uniform samplerRECT colorMap : TEXUNIT1;

void main(
    in float2 iTexCoord : TEXCOORD0,
    out float4 oColor : COLOR
){
    oColor = texRECT(colorMap,iTexCoord);
}
