Member Function Documentation

float32 IMuli3DBaseShader::fGetFloat ( uint32 i_iIndex )

Returns the value of a single float-constant.
Parameters:

[in] i_iIndex index of the constant.

const matrix44 & IMuli3DBaseShader::matGetMatrix ( uint32 i_iIndex )

Returns the value of a matrix-constant.
Parameters:

[in] i_iIndex index of the constant.

result IMuli3DBaseShader::SampleTexture ( vector4 & o_vColor,

uint32 i_iSamplerNumber,

float32 i_fU,

float32 i_fV,

float32 i_fW = 0.0f,

const vector4 * i_pXGradient = 0,

const vector4 * i_pYGradient = 0

) [protected]

Samples the texture and returns the looked-up color. This simply functions simply forwards the sampling-call to the device.
Parameters:

[out] o_vColor receives the color of the pixel to be looked up.

[in] i_iSamplerNumber number of the sampler.

[in] i_fU u-component of the lookup-vector.

[in] i_fV v-component of the lookup-vector.

[in] i_fW w-component of the lookup-vector.

[in] i_pXGradient partial derivatives of the texture coordinates with respect to the screen-space x coordinate (optional, base for mip-level calculations).

[in] i_pYGradient partial derivatives of the texture coordinates with respect to the screen-space y coordinate (optional, base for mip-level calculations).

Returns:
s_ok if the function succeeds.
e_invalidparameters if one or more parameters were invalid.

void IMuli3DBaseShader::SetDevice ( class CMuli3DDevice * i_pDevice ) [protected]

Accessible by CMuli3D - Sets the rendering-device.
Parameters:

[in] i_pDevice the device.

void IMuli3DBaseShader::SetFloat ( uint32 i_iIndex,

float32 i_fValue

)

Sets a single float-constant.
Parameters:

void IMuli3DBaseShader::SetVector ( uint32 i_iIndex,

const vector4 & i_vVector

)

Sets a vector4-constant.
Parameters:
