hlslf - Translation profile to DirectX 9's High Level Shader Language for pixel shaders. hlslf This Direct3D profile translates Cg into DirectX 9's High Level Shader Language (HLSL) for pixel shaders. The compiler output for this profile conforms to the textual high-level language defined by DirectX 9's High Level Shading Language. See: http://msdn.microsoft.com/en-us/library/bb509561.aspx The limitations of the hlslf profile depend on what HLSL profile to which the translated HLSL code is compiled. Requires Direct3D 9 support. None. In general, the Cg data types translate to the HLSL data types with the same name. NVIDIA GPUs may use half-precision floating-point when the Partial Precision instruction modifier is specified. Half-precision floating-point is encoded with a sign bit, 10 mantissa bits, and 5 exponent bits (biased by 16), sometimes called s10e5. The float data type corresponds to a floating-point representation with at least 24 bits. NVIDIA GPUs supporting hlslf use standard IEEE 754 single-precision floating-point encoding with a sign bit, 23 mantissa bits, and 8 exponent bits (biased by 128), sometimes called s10e5. Older ATI GPUs use 24-bit floating-point. The fixed data type is treated like half.
