Constructor & Destructor Documentation

BumpMapCore()

scg::BumpMapCore::BumpMapCore

(

)

Contructor.

~BumpMapCore()

virtual scg::BumpMapCore::~BumpMapCore ( )

virtual

Destructor.

Member Function Documentation

create()

static BumpMapCoreSP scg::BumpMapCore::create ( )

static

Create shared pointer.

render()

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

virtual

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

Reimplemented from scg::Texture2DCore.

renderPost()

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

virtual

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

Reimplemented from scg::Texture2DCore.

setNormalMap()

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

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

Parameters

width	normal map width
height	normal map 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
