virtual

Destructor.

Member Function Documentation

create()

static Texture2DCoreSP scg::Texture2DCore::create ( )

static

Create shared pointer.

render()

virtual void scg::Texture2DCore::render ( RenderState *  renderState )

virtual

Render core, i.e., bind texture and post-multiply current texture matrix by local texture matrix.

Reimplemented from scg::TextureCore.

Reimplemented in scg::BumpMapCore.

renderPost()

virtual void scg::Texture2DCore::renderPost ( RenderState *  renderState )

virtual

Render core after traversing sub-tree, i.e., restore previous texture matrix and bind previous texture.

Reimplemented from scg::TextureCore.

Reimplemented in scg::BumpMapCore.

rotate2D()

void scg::Texture2DCore::rotate2D

(

GLfloat

angleDeg

)

Rotate texture around (0,0,1) axis (post-multiply local texture matrix by transformation).

Parameters

angleDeg

rotation angle (degrees)

scale2D()

void scg::Texture2DCore::scale2D

(

glm::vec2

scaling

)

Scale texture in s and t direction (post-multiply local texture matrix by transformation).

Parameters

scaling

scaling factors in s and t direction

setTexture()

void scg::Texture2DCore::setTexture	(	GLsizei	width,
		GLsizei	height,
		const unsigned char *	rgbaData,
		GLenum	wrapModeS,
		GLenum	wrapModeT,
		GLenum	minFilter,
		GLenum	magFilter
	)

Create texture from RGBA image with given parameters. If minFilter is GL_*_MIPMAP_* (see below), a mipmap is created from the given image.

Parameters

width	texture width
height	texture height
rgbaData	array of RGBA values
wrapModeS	GL_CLAMP, GL_CLAMP_TO_BORDER, GL_CLAMP_TO_EDGE, GL_MIRRORED_REPEAT, or GL_REPEAT
wrapModeT	see wrapModeS
minFilter	GL_NEAREST, GL_LINEAR, GL_NEAREST_MIPMAP_NEAREST, GL_LINEAR_MIPMAP_NEAREST, GL_NEAREST_MIPMAP_LINEAR, or GL_LINEAR_MIPMAP_LINEAR
magFilter	GL_NEAREST or GL_LINEAR
