Detailed Description

Constructor & Destructor Documentation

chai3d::cTexture2d::cTexture2d ( )

Constructor of cTexture2d.

chai3d::cTexture2d::~cTexture2d ( )

virtual

Destructor of cTexture2d.

Member Function Documentation

static cTexture2dPtr chai3d::cTexture2d::create ( )

inlinestatic

cTexture2dPtr chai3d::cTexture2d::copy ( )

This method creates a copy of itself.

Returns: Pointer to new object.

void chai3d::cTexture2d::renderInitialize ( cRenderOptions & a_options )

virtual

This method enables texturing and set this texture as the current texture.

Parameters

a_options Rendering options.

Reimplemented from chai3d::cTexture1d.

Reimplemented in chai3d::cTextureVideo, and chai3d::cTexture3d.

void chai3d::cTexture2d::renderFinalize ( cRenderOptions & a_options )

virtual

This method disable texture rendering once triangles have been rendered.

Parameters

a_options Rendering options.

Reimplemented from chai3d::cTexture1d.

Reimplemented in chai3d::cTexture3d.

void chai3d::cTexture2d::setWrapModeT ( const GLint & a_wrapModeT )

virtual

This method Ssts the wrap parameter for texture coordinate t to either GL_CLAMP or GL_REPEAT.

GL_CLAMP causes t coordinates to be clamped to the range [0,1] and is useful for preventing wrapping artifacts when mapping a single image onto an object.

GL_REPEAT causes the integer part of the t coordinate to be ignored; OpenGL uses only the fractional part, thereby creating a repeating pattern. Border texture elements are accessed only if wrapping is set to GL_CLAMP.

Parameters

a_wrapModeT value shall be either GL_REPEAT or GL_CLAMP.

GLint chai3d::cTexture2d::getWrapModeT ( ) const

void chai3d::cTexture2d::update ( cRenderOptions & a_options )

protectedvirtual

This method updates the texture from memory data to GPU.

Parameters

a_options Rendering options.

Reimplemented from chai3d::cTexture1d.

Reimplemented in chai3d::cTexture3d.
