List of all members.

Detailed Description

This is the texture base-class, which defines functions that are common to all different sorts of textures.

Public Member Functions

IMuli3DBaseTexture (class CMuli3DDevice *i_pParent)

virtual result SampleTexture (vector4 &o_vColor, float32 i_fU, float32 i_fV, float32 i_fW, const vector4 *i_pXGradient, const vector4 *i_pYGradient, const uint32 *i_pSamplerStates)=0

Protected Attributes

Constructor & Destructor Documentation

IMuli3DBaseTexture::~IMuli3DBaseTexture ( ) [protected, virtual]

Accessible by IBase. The destructor is called when the reference count reaches zero.

IMuli3DBaseTexture::IMuli3DBaseTexture ( class CMuli3DDevice * i_pParent ) [protected]

Texture constructor.
Parameters:

[in] i_pParent a pointer to the parent CMuli3DDevice-object.

Member Function Documentation

virtual m3dtexsampleinput IMuli3DBaseTexture::eGetTexSampleInput ( ) [protected, pure virtual]

Returns a member of enum m3dtexsampleinput, which determines the type of input vector SampleTexture() will receive when sampling the texture.

Implemented in CMuli3DCubeTexture, CMuli3DTexture, and CMuli3DVolumeTexture.

CMuli3DDevice * IMuli3DBaseTexture::pGetDevice ( )

Returns a pointer to the associated device. Calling this function will increase the internal reference count of the device. Failure to call Release() when finished using the pointer will result in a memory leak.

virtual result IMuli3DBaseTexture::SampleTexture ( vector4 & o_vColor,

float32 i_fU,

float32 i_fV,

float32 i_fW,

const vector4 * i_pXGradient,

const vector4 * i_pYGradient,

const uint32 * i_pSamplerStates

) [protected, pure virtual]

Samples the texture and returns the looked-up color.
Parameters:

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

[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. If 0 the base mip-level will be chosen and the minification filter will be used for texture sampling.

[in] i_pYGradient partial derivatives of the texture coordinates with respect to the screen-space y coordinate. If 0 the base mip-level will be chosen and the minification filter will be used for texture sampling.

[in] i_pSamplerStates texture sampler states.

Returns:
s_ok if the function succeeds.

Implemented in CMuli3DCubeTexture, CMuli3DTexture, and CMuli3DVolumeTexture.
