Detailed Description

Texture2D is our RGBA image texture class. It features several methods for loading the texel data, like direct file access, or creating a blank texture on construction.

Constructor & Destructor Documentation

Texture2D::Texture2D	(	const char *	path,
		GLenum	wrapS = GL_REPEAT,
		GLenum	wrapT = GL_REPEAT,
		GLenum	magFilter = GL_LINEAR,
		GLenum	minFilter = GL_LINEAR_MIPMAP_LINEAR
	)

Loads a texture from a file. The loader will check the file-extension, to find out the format of the image. At the moment, only OpenEXR ist supported.

Texture2D::Texture2D	(	V2i	size,
		Color4f	color = Color4f(0.0),
		GLenum	wrapS = GL_REPEAT,
		GLenum	wrapT = GL_REPEAT,
		GLenum	magFilter = GL_LINEAR,
		GLenum	minFilter = GL_LINEAR_MIPMAP_LINEAR
	)

Creates a blank texture. This can be useful for procedural textures e.g. for effects or for the preparation of a renderbuffer.

Texture2D::Texture2D	(	V2i	size,
		Color4f *	pixels,
		GLenum	wrapS = GL_REPEAT,
		GLenum	wrapT = GL_REPEAT,
		GLenum	magFilter = GL_LINEAR,
		GLenum	minFilter = GL_LINEAR_MIPMAP_LINEAR
	)

Creates a texture, by making a copy of the supplied surface.

Member Function Documentation

void Texture2D::build_mipmaps

(

)

Rebuild the mipmap-Levels of the texture.

GLuint Texture2D::get_texture_name

(

)

[inline]

Returns the openGL texture name of this texture.

void Texture2D::send_to_GPU

(

)

Load the pixel data as texture. You only have to use this, when the pixel-data has changed. This will be done automatically, a Texture-contruction.
