Detailed Description

Wraps an OpenGL texture object representing and managing all the supported texture types.

Remarks:

Many of the parameters used to create a Textures are the same used by glTexImage1D/2D/3D etc. See the following for more information:

• http://www.opengl.org/sdk/docs/man/xhtml/glTexImage1D.xml
• http://www.opengl.org/sdk/docs/man/xhtml/glTexImage2D.xml
• http://www.opengl.org/sdk/docs/man/xhtml/glTexImage3D.xml

Note:

A TexParameter defines a set of variables associated to a Texture while TexGen and TexEnv define a set of variables associated to a TextureSampler.

• getTexParameter() and TexParameter
• createTexture()
• setMipLevel()

bool Texture::setMipLevel	(	int	mip_level,
		const Image *	img,
		bool	gen_mipmaps

Copies the texture image to the specified mip-maping level.

This function can be useful to specify one by one the mipmapping images or to create texture animation effects.

Parameters:

mip_level	The mip-mapping level to be modified.
img	The Image containing the pixels to be copied into the specified mip-mapping level.
gen_mipmaps	If true automatically generates the mip-mapping images for the levels below mip_level.

Remarks:

Before calling this function one of the two createTexture() methods must have been called.

Note:

The mip-map level is updated immediately therefore an OpenGL context must be active when calling this function.
